Titanium Dioxide (9%) - goodie
What-it-does: sunscreen, colorant
Titanium Dioxide is one of the two members of the elite sunscreen group called physical sunscreens (or inorganic sunscreens if you’re a science geek and want to be precise).
Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of theskin. While this categorization is easy and logicalit turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum).
Anyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable. Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less goodat 350-400 nm (UVA I) range. Regular sized Titanium Dioxide also has a great safetyprofile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters).
The disadvantage of Titanium Dioxide is that it's not cosmetically elegant, meaning it's a white, "unspreadable" mess. Sunscreens containingTitanium Dioxideare often hard to spread on the skin and they leave a disturbing whitishtint. The cosmetic industry is, of course, really trying to solve this problemand the best solution so far is using nanoparticles. The itsy-bitsy Nano-sized particles improveboth spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns.
The main concernwith nanoparticles is that they are so tiny that they are absorbedinto the skin more than we want them (ideally sunscreen should remain on the surface of the skin). Once absorbed they might form unwanted complexes with proteins and they might promote the formation of evil free radicals. But do not panic, these are concerns under investigation. A 2009 review article about the safety of nanoparticles summarizes this, "to date, in-vivo and in-vitro studies have not demonstrated percutaneous penetration of nanosized particles in titanium dioxide and zinc oxide sunscreens". The English translation is, so far it looks like sunscreenswith nanoparticlesdo stay on the surface of the skin where they should be.
All in all,Titanium Dioxide is a famous sunscreen agent and for good reason, it gives broad spectrum UV protection (best at UVB and UVA II), it's highly stable, and it has a good safety profile. It's definitely one of the best UV-filter agents we have today, especially in the US where new-generation Tinosorb filters are not (yet) approved.
Zinc Oxide (7%) - goodie
What-it-does: sunscreen | Irritancy: 0 | Comedogenicity: 1
When it comes to sunscreen agents, Zinc Oxide ispretty much in aleague of its own. It's a physical (or inorganic) sunscreenthat has a lot in common with fellow inorganic sunscreen Titanium Dioxide(TiO2) but a couple of things make it superior even toTiO2.
If physical sunscreensdon't tell you anything, go ahead and read about the basics here. Most of what we wrote about Titanium Dioxideis also true for Zinc Oxide so we will focus here on the differences.
The first main difference is that while TiO2 gives a nice broad spectrum protection, Zinc Oxide has an even nicerand even broader spectrum protection. It protects against UVB, UVA II, and UVA I almost uniformly, and is considered to be the broadestrange sunscreen available today.
It'salso highly stableand non-irritating. So much sothat Zinc Oxide also counts as a skin protectant and anti-irritant. It's also often used to treat skin irritationssuch as diaper rash.
As for the disadvantages, Zinc Oxide is also not cosmetically elegant. Itleaves a disturbing whitish tint on the skin, although, according toa2000research paper by Dr. Pinnell, it's slightlyless white than TiO2. Still, it's white and disturbing enough to use Zinc Oxide nanoparticles more and more often.
We wrote more about nanoparticles and the concerns around them here, but the gist is that if nanoparticles were absorbed into the skin that would be a reason for legitimate health concerns. But luckily, so far research shows thatsunscreen nanoparticles are not absorbedbut remain on the surface of the skin or in the uppermost (dead) layer of the skin. This seems to be true even if the skin is damaged, for example, sunburnt.
All in all, if you've found a Zinc Oxide sunscreen that you are happy to use every single day, that's fantastic and we suggest you stick with it. It's definitely one of the best, or probably even the best option out there for sun protection available worldwide.
Water
Also-called: Aqua | What-it-does: solvent
Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product.
It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water.
Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.
One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time.
Glycerin - superstar
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
- A natural moisturizer that’s also in our skin
- A super common, safe, effective and cheap molecule used for more than 50 years
- Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
- Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40%
- High-glycerin moisturizers are awesome for treating severely dry skin

C12-15 Alkyl Benzoate
What-it-does: emollient, antimicrobial/antibacterial
An often used emollient with a light and silky feel. It's very mild to both skin and eyes and spreads nicely and easily. It's often used in sunscreens as it's also an excellent solvent for sunscreen agents.
Dimethicone
What-it-does: emollient | Irritancy: 0 | Comedogenicity: 1
Probably themost common silicone of all. It is a polymer (created from repeating subunits) molecule and has different molecular weight and thus different viscosity versions from water-light to thickliquid.
As for skincare, it makes the skin silky smooth, creates a subtle gloss and forms a protective barrier (aka occlusive). Also, works well to fill in fine lines and wrinkles and give skin a plump look (of course that is only temporary, but still, it'snice). There are also scar treatment gels out there using dimethicone as their base ingredient. It helps to soften scars and increase their elasticity.
As for hair care, it is a non-volatile silicone meaning that it stays on the hair rather than evaporates from it andsmoothes the hairlike no other thing. Depending on your hair type, it can bea bit difficult to wash out and might cause some build-up (btw, this is not true to all silicones, only the non-volatile types).
Isododecane
What-it-does: emollient, solvent
Aclear, colorless and odorless, highly volatile (meaning it does not absorb into the skin but evaporates from it) liquid that's used as an emollient. It gives a nicenon-oily light skin feeland it can improvethe slip of the formula without leaving a tacky residue behind.
It's also popular in make-up products as its volatility makes mascarasand foundations last longer. If that would not be enough, it's also an excellent solvent, and it's a regular not only on the ingredients lists of make-ups but also on makeup removers.
Styrene/Acrylates Copolymer
A film-forming polymer (big molecule from repeated subunits) to create water-resistant sunscreen formulas. It also improves the SPF value of sunscreen formulas (approx. 11-18% boost in SPF per 1%Styrene/Acrylates Copolymer).
Glyceryl Stearate
What-it-does: emollient, emulsifying | Irritancy: 0 | Comedogenicity: 1
A super common, waxy, white, solid stuff that helps water and oil to mix together, gives body to creams and leaves the skin feeling soft and smooth.
Chemically speaking, it is the attachment of a glycerin molecule to the fatty acid calledstearic acid. It can be produced from most vegetable oils (in oils three fattyacidmolecules are attached to glycerin instead of just one like here) in a pretty simple, "green" process that is similar to soap making. It's readily biodegradable.
It also occurs naturally in our body and is used as a food additive. As cosmetic chemistColins writes it, "its safety really is beyond any doubt".
Butyloctyl Salicylate
What-it-does: solvent
A nice, multi-functional helper ingredient that's especially useful in sunscreens. It cansolubilize somecommonly used UV-filterslike Oxybenzone or Avobenzone and it can also help to increase the SPF rating of sunscreens. It's also cosmetically elegant, has excellent spreadability and apleasant, moisturizing skin feel. Oh, and according to Wikipedia, it even helps to stabilize famously unstable UVA-filter, Avobenzone.
Dicaprylyl Carbonate
What-it-does: emollient
A clear, colorless, almost odorless oil that spreads nicely and easily and givesa velvet dry skin feel. It is good friends with sunscreen agents and helps to solubilize them. Also, it makes sunscreens feel lighter and spread easier.
Propanediol
Also-called: Zemea | What-it-does: solvent, moisturizer/humectant
Propanediol is a natural alternative for the often usedand often bad-mouthed propylene glycol. It's produced sustainably from corn sugar and it's Ecocert approved.
It's quite a multi-tasker: can be used to improve skin moisturization, as a solvent, to boost preservative efficacyor to influence the sensory properties of the end formula.
Stearic Acid
What-it-does: emollient, viscosity controlling | Irritancy: 0 | Comedogenicity: 2-3
A common multi-tasker fatty acid. It makes your skin feel nice and smooth (emollient), gives body to cream type products and helps to stabilize water and oilmixes (aka emulsions).
Aluminum Hydroxide
What-it-does: emollient, moisturizer/humectant, viscosity controlling
Officially, CosIng (the official EU ingredient database) lists Aluminum Hydroxide 's functions as opacifying(making the product white and non-transparent), as well as emollient and skin protectant.
However, with a little bit of digging, it turns out Aluminum Hyroxide often moonlights as a protective coating for UV filter superstar Titanium Dioxide. Specifically, it protects our skin from the harmful effects of nasty Reactive Oxygen Species (free radicals derived from oxygen such as Superoxide and Hydrogen Peroxide)generated when Titanium Dioxide is exposed to UV light. Btw, chlorine inswimming pool waterdepletes this protective coating, so one more reason to reapply your sunscreen after a dip in the pool on holiday.
Other than that,Aluminum Hydroxide also often shows up in composite pigment technologies where it is used the other way around (as the base material and not as the coating material) and helps to achieve higher color coverage with less pigment.
PEG-100 Stearate
What-it-does: surfactant/cleansing, emulsifying | Irritancy: 0 | Comedogenicity: 0
A very common water-loving surfactant and emulsifier that helps to keep water and oil mixed nicelytogether.
It's often paired with glyceryl stearate- the twotogether forma super effective emulsifier duo that's salt and acid tolerant and works over a wide pH range. It also gives a "pleasing product aesthetics", so no wonder it's popular.
Sorbitan Stearate
What-it-does: emulsifying | Irritancy: 1 | Comedogenicity: 0
A popular, vegetable-derived oil-loving emulsifier that helps water to mix with oil. In itself, it is suitable for water-in-oil emulsions (where water droplets are dispersed in oil), but it is more often used as a co-emulsifier next to other,water-loving emulsifiers.
Chemically speaking, it comes from the attachment of sorbitan (a dehydrated sorbitol (sugar) molecule) with the fatty acid Stearic Acid, that creates a partly water (the sorbitan part) and partly oil soluble (stearic part) molecule.
PEG-8 Laurate
What-it-does: emulsifying, surfactant/cleansing
We don't have description for this ingredient yet.
Ceramide NP - goodie
Also-called: Ceramide 3 | What-it-does: skin-identical ingredient
One of the many types of ceramides that can be found naturally in the upper layer of the skin. Ceramides make upabout 50% of the goopy stuff that's between our skin cells and play a super important role in having a healthy skin barrier and keeping the skin hydrated. It works even better when combined with its pal, Ceramide1.
We wrote way more about ceramides at ceramide 1, so click here to know more.
Ceramide AP - goodie
Also-called: Ceramide 6 II | What-it-does: skin-identical ingredient
A typeof ceramidethat can be found naturally in the upper layer of the skin. Ceramides make up 50% of the goopy stuff that's between our skin cells and play a super important role in having a healthy skin barrier and keeping the skin hydrated.
We have written way more about ceramides at ceramide 1, so click here to know more.
Ceramide EOP - goodie
Also-called: Ceramide 1 | What-it-does: skin-identical ingredient
Ceramides get quite a lot of hype recently and good news: there is a reason for that. But before we go into the details, let's just quickly define what the heck ceramides are:
They are waxy lipids that can be found naturally in the outer layer of the skin (called stratum corneum - SC). And they are there in big amounts! The goopy stuff between our skin cells is called extracellular matrix that consists mainly of lipids. And ceramides are about 50% of those lipids (the other important ones are cholesterol with 25% and fatty acids with 15%).
Ok, so now we know what ceramides are, let's see what they do in our skin: research shows clearly that they play a super important role in keeping the skin barrier healthy and the skin hydrated. If ceramides in the skin are decreased, more water can evaporate from the skin and there is less water remaining in the skin. So ceramides form kind of a "water-proof" protecting layerand make sure that our skin remains nice and hydrated.
Now the question is only this: If we put ceramides all over our face do theywork as well as ceramides already naturally in our skin? Well, the answer is probably a no, but they do work to some extent. The BeautyBrains blog made a fantastic article about ceramides and they have listed a couple of examples about studies showing that ceramides - especially when used in certain ratios with cholesterol and fatty acids - do hydrate the skin and can help to repair the skin barrier.
So far we were writing about ceramides in plural. It's because there are lots of different ceramides, a 2014article writes that currently 12 base classes of ceramides are known with over 340 specific species.Chemically speaking, ceramides are the connection of a fatty acid and a sphingoid base and both parts can have different variations that result in the different types of ceramides.
Our current one, Ceramide 1, or morerecently called CeramideEOP, was the first one that was identified in 1982 and it's a special snowflake. It contains the essential fatty acid, linoleic acid and has a unique structure. It's believed that ceramide 1 plays a "binding role" in the lipid layers of the extracellular matrix. Along with ceramides 4 and 7, they also play a vital role in epidermal integrity and serve as the main storage areas for linoleic acid (a fatty acid that's alsovery important for barrier repair).
Oh, and one more thing: alkaline pH inhibits enzymes that help ceramide synthesis in our skin. So if you use a soap and you notice your skin is becoming dry, now you know why.
Sorbitan Isostearate
What-it-does: emulsifying | Irritancy: 0 | Comedogenicity: 1-2
A handy helper ingredient that helps water and oil to mix nicely together, aka emulsifier. It is especially recommended for protective, baby care and general purpose emollient creams.
It also helps to disperse insoluble particles (think color pigments or zinc/titanium dioxide sunscreen) nice and even in cosmetic formulas.
Carbomer
What-it-does: viscosity controlling, emulsion stabilising | Irritancy: 0 | Comedogenicity: 1
A big molecule created from repeated subunits (a polymer of acrylic acid) that magically converts a liquidinto a nice gel formula. It usually has to be neutralized with a base (such as sodium hydroxide) for the thickening to occur and it creates viscous, clear gels that also feel nice and non-tacky on the skin. No wonder, it is a very popular and common ingredient. Typically used at 1% or less in most formulations.
Cetearyl Alcohol
What-it-does: emollient, viscosity controlling, emulsifying, emulsion stabilising, surfactant/cleansing | Irritancy: 1 | Comedogenicity: 2
An extremely common multitasker ingredient that gives your skin a nice soft feel (emollient) and gives body to creams and lotions. It also helps to stabilize oil-water mixes (emulsions), though it does not function as an emulsifier in itself. Its typical use level in most cream type formulas is 2-3%.
It’s a so-called fatty alcohol, a mix of cetyl and stearyl alcohol, other two emollient fatty alcohols. Though chemically speaking, it is alcohol (as in, it has an -OH group in its molecule), its properties are totally different from the properties of low molecular weight or drying alcohols such as denat. alcohol. Fatty alcohols have a long oil-soluble (and thus emollient) tailpart that makes them absolutelynon-drying and non-irritating and are totally ok for the skin.
Ceteareth-20
What-it-does: emulsifying, surfactant/cleansing | Irritancy: 3 | Comedogenicity: 2
A common functional ingredient that helps to keep the oil-loving and water-loving ingredients together (emulsifier), stabilizes and thickens the products.
Chemically speaking, it is ethoxylated Cetearyl alcohol, meaning that some ethylene oxide is added to the fatty alcohol to increase the water-soluble part in the molecule. The result is thatthe mainly oil soluble, emollient fatty alcohol is converted to an emulsifier molecule that keeps oil and water mixedin creams. The numberin the name ofCeteareth emulsifiers refersto the average number of ethylene oxide molecules added and 20 makes a good emulsifier.
Triethoxycaprylylsilane
A clear, light yellow liquid that is used to coat pigments (such as inorganic sunscreen agents or colorants) in cosmetic products. The coating helps to stabilize pigments in the formulas and also helps them to spread easily and evenly on the skin.
Dimethiconol
What-it-does: emollient, moisturizer/humectant
A thick, high molecular weight silicone that is usually diluted in another, lighter silicone fluid (like dimethicone or cyclopentasiloxane). Thedimethiconol containing silicone blends leave a silky smooth, non-greasy film on the skin.
Sodium Citrate
What-it-does: chelating, buffering
A little helper ingredient that is used to adjustthe pH of the product. It also helps to keep products stay nice longer by neutralizingthe metal ionsin the formula (they usually come from water).
Sodium Lauroyl Lactylate
What-it-does: emulsifying
A helper ingredient that's used as a co-emulsifier (meaning next to other emulsifiers in the formula it helps water and oil to mix) and as a stabilization agent for foams. Also, has some antimicrobial activity so it can help to boost the effectiveness of the preservative system.
Sodium Dodecylbenzenesulfonate
What-it-does: surfactant/cleansing, emulsifying
We don't have description for this ingredient yet.
Myristic Acid
What-it-does: surfactant/cleansing, emulsifying, perfuming | Irritancy: 0 | Comedogenicity: 3
A 14 carbon length fatty acid that can be naturally found innutmeg,palm kernel oil, coconut oil and butter fat. It's used as a foam building cleansing agent. Paula Begoun writes that it can be a bit drying to the skin.
Sodium Hyaluronate - goodie
What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
It’s the - sodium form - cousin of the famous NMF,hyaluronic acid(HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here. The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water.
As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephenwrites on reddit "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution".
In spite of this, if you search for "hyaluronic acid vs sodium hyaluronate" you will find on multiple places that sodium hyaluronate is smaller and can penetrate the skin better. Chemically, this is definitely not true, as the two forms are almost the same, both are polymers and the subunits can be repeated in both forms as much as you like. (We also checkedProspector for sodium hyaluronate versions actually used in cosmetic products and found that the most common molecular weight was 1.5-1.8 million Da that absolutely counts as high molecular weight).
What seems to be a true difference, though, is that the salt form is more stable, easier to formulate andcheaper so it pops up more often on the ingredient lists.
If you wanna become a real HA-and-the-skin expert you can read way more about the topic at hyaluronic acid(including penetration-questions, differences between high and low molecular weight versions and a bunch of references to scientific literature).
Cholesterol - goodie
What-it-does: skin-identical ingredient, emollient | Irritancy: 0 | Comedogenicity: 0
It's one of the important lipids that can be found naturally in the outer layer of the skin. About 25% of the goopy stuff between our skin cells consists of cholesterol. Together with ceramides and fatty acids, they play a vital role in having a healthy skin barrier and keeping the skin hydrated.
Apart from being an important skin-identical ingredient, it's also an emollient and stabilizer.
Palmitic Acid
What-it-does: skin-identical ingredient, emollient, emulsifying | Irritancy: 0 | Comedogenicity: 2
A fatty acid that can be found naturally in the skin. In fact, it's the most common saturated fatty acidfound in animals and plants.
As for skincare, it can make the skin feel nice and smooth in moisturizers (emollient) or it can act as a foam building cleansing agent in cleansers. It's also a very popular ingredient in shaving foams.
Phenoxyethanol
What-it-does: preservative
It’s pretty much the current IT-preservative. It’s safe and gentle, but even more importantly, it’s not a feared-by-everyone-mostly-without-scientific-reason paraben.
It’s not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic.
Other than having a good safety profile and being quite gentle to the skin it has some other advantages too. It can be used in many types of formulations as it has great thermal stability (can be heated up to 85°C) and works on a wide range of pH levels (ph 3-10).
It’s often used together with ethylhexylglycerin as it nicely improves the preservative activity of phenoxyethanol.
Chlorphenesin
What-it-does: preservative, antimicrobial/antibacterial
A little helper ingredient that works as a preservative. It works againstbacteria and some species of fungi and yeast. It's often combined with IT-preservative, phenoxyethanol.
Tocopherol - goodie
Also-called: Vitamin E | What-it-does: antioxidant | Irritancy: 0-3 | Comedogenicity: 0-3
- Primary fat-soluble antioxidant in our skin
- Significant photoprotection against UVB rays
- Vit C + Vit E work in synergy and provide great photoprotection
- Has emollient properties
- Easy to formulate, stable and relatively inexpensive
Read all the geeky details about Tocopherol here >>
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer
Also-called: Sepinov EMT 10 | What-it-does: viscosity controlling, emulsion stabilising
This long-named, polymer molecule (big molecule from repeated subunits) is a helper ingredient that's good at emulsifying andstabilizing oils into water-based formulas. Italso acts as a thickening and gelling agent thatcreates nice, non-sticky and supple textures.It works over a very wide pH range (3-12)and can be used to thicken up low-ph formulas, such as exfoliants. Its recommended used range is 0.3-3%.
Caprylyl Glycol
What-it-does: moisturizer/humectant, emollient, deodorant
It’s a handy multi-tasking ingredient that gives the skin a nice, soft feel. At the same time, it also boosts the effectiveness of other preservatives, such as the nowadays super commonly used phenoxyethanol.
The blend of these two (caprylyl glycol + phenoxyethanol) is called Optiphen, which not only helps to keep your cosmetics free from nasty things for a long time but also gives a good feel to the finished product. It's a popular duo.
Citric Acid
What-it-does: buffering
Citric acid comes from citrus fruits and is an AHA. If these magic three letters don’t tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA.
So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh.
There is also some research showing that citric acid with regular use (think three monthsand 20% concentration) can help sun-damaged skin, increase skin thickness and some nice hydrating things called glycosaminoglycans in the skin.
But according to a comparative study done in 1995, citric acid has less skin improving magic properties than glycolic or lactic acid. Probably that’s why citric acid is usually not used as an exfoliant but more as a helper ingredient in small amounts to adjust the pH of a formulation.
Xanthan Gum
What-it-does: viscosity controlling, emulsion stabilising
It's one of the most commonly used thickeners and emulsion stabilizers. If the product is too runny, a little xanthan gum will make it more gel-like.Used alone, it can make the formula sticky and it is a good team player so it is usually combined with other thickeners and so-calledrheology modifiers (helper ingredients that adjust the flow and thus the feel of the formula). The typical use level of Xantha Gum is below 1%, it is usually in the 0.1-0.5% range.
Btw, Xanthan gum is all natural, a chain of sugar molecules (polysaccharide) produced from individual sugar molecules (glucose and sucrose) via fermentation. It’s approved by Ecocert and also used in the food industry(E415).
Phytosphingosine - goodie
What-it-does: skin-identical ingredient, cell-communicating ingredient, anti-acne, antimicrobial/antibacterial
It's a type of lipid, a so-calledsphingoid base that can be found naturally in the upper layer of the skin. It's found both in "free-form" and as part of famous skin lipids, ceramides.
There is emerging research about Phytosphingosine that shows that it has antimicrobial and cell-communicating properties and is considered part of the skin's natural defense system.
A 2007 study showed thatPhytosphingosine even works againstevil acne-causing bacteria,Propionibacterium acnes and shows promise as a complementing active ingredient in treating acne-prone skin thanks to its anti-inflammatory and antimicrobial activities.
A nice one to spot in the ingredient list. :)
Polyhydroxystearic Acid
What-it-does: emulsifying
A so-called dispersant or dispersing agent that's used in inorganic (titanium dioxide/zinc oxidebased) sunscreens or in make-up products to help to distribute the pigments nicely and evenly on the skin. It's also claimed to increase the UV absorption of the sunscreen formula as well as to reduce the annoying white cast left behind by inorganic sunscreens.
Polysorbate 60
What-it-does: emulsifying, surfactant/cleansing
A common little helper ingredient thathelps water and oil to mixtogether, aka emulsifier.
Ethylhexylglycerin
What-it-does: preservative, deodorant
If you have spottedethylhexylglycerinon the ingredient list, most probably you will see there also the current IT-preservative,phenoxyethanol. They are good friends becauseethylhexylglycerincan boost the effectiveness of phenoxyethanol (and other preservatives) and as an added bonus it feels nice on the skin too.
Also,it's an effective deodorant and a medium spreadingemollient.
