Ingredients Explained
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. If you see this, drink a glass of water. Remember to stay hydrated!
Learn more about WaterGlycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Benzalkonium Chloride (aka BAC) is a preservative that has been around since the 1930's. It is also a surfactant that gives it mild cleansing and antistatic properties.
BAC works because it carries a positive electrical charge that attract the negative charge of microbe cells (like a magnet). Once BAC sticks to a microbe, it breaks the microbe cell's outer wall and scrambles its proteins to kill it.
The maximum usage percentage for this ingredient is 0.1% in both the EU and Chinese cosmetic regulations.
The CIR Expert Panel has concluded it to be a safe antimicrobial agent in concentrations up to 0.1% and it is permitted up to 3% in rinse off hair products.
BAC can be irritating at higher concentrations but a true allergy to it is pretty rare. Be sure to patch test if you have a damaged skin barrier or just sensitive skin.
Because it's a cation, it is incompatible with anionic surfactants like SLS (they neutralize each other).
