1
What it does: Skin Conditioning, Solvent
Community Rating: Loved

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

2
What it does: Absorbent, Emulsion Stabilising
Community Rating: Liked

Bentonite is an aluminium phyllosilicate clay with great absorbent properties. The name 'bentonite' comes from the area where the largest source is found: Fort Benton, Wyoming.

As a clay, bentonite is often used to absorb excess oil and provide exfoliation. It has also been shown to have some antibacterial and anti-inflammatory properties. Studies show bentonite was effective at calming dermatitis from poison ivy and in diaper dermatitis of infants. Bentonite has also been shown to act as a barrier against toxic compounds on your skin.

Sunscreens containing bentonite display higher water resistance and stay on the skin for much longer. The sunscreens containing bentonite also show higher potency and UV light absorbtion.

Bentonite is naturally created from volcanic ash and several natural weathering/hydrothermal processes.

A common usage of bentonite is removing excess protein from white wines. Bentonite contains a property of being able to absorb large amounts of protein from aqueous solutions.

Phyllosilicate clay has a structure formed by sheets.

3
What it does: Emulsifying
Community Rating: Very Disliked

Polysorbate 20 is made by combining ethoxylation of sorbitan, ethylene oxide, and lauric acid. It is a mild cleansing agent, surfactant, and emulsifier.

As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.

Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.

The lauric acid used to create Polysorbate 20 is often derived from coconuts.

Polysorbate 20 may not be fungal acne safe.

Very effective at spot treating, if left overnight. Very irritating, however, if left on a large area on the face. Use for direct pimples only.
