What-it-does: emulsifying
Irritancy: 1
Comedogenicity: 2


A waxy solid material that helps oil and water to mix together, aka emulsifier. It is derived from the fatty alcohol called stearyl alcohol by ethoxylating it and thus making the molecule more water-soluble.

The end result is a mostly water-loving emulsifier, also called solubilizer that can help to dissolve small amounts of oil-loving ingredients into water-based products. Or it can be combined with more oil-loving emulsifiers (such as its sister, Steareth-2) to create stable emulsions.
