Know Your Ingredients: Decyl Glucoside

by Gio


What it is
Decyl Glucoside is derived by reacting decyl alcohol with a form of glucose.

What it does
Decyl Glucoside is a gentle surfactant: it helps dirt and oil to be mixed with water so that they can be rinsed off. Because it has an alkaline ph (7 to 9.5), it needs to be used together with an acidic ingredient, such as citric acid, that will bring it down to the ph of the skin.

Side effects
Decyl Glucoside is generally considered to be safe.

Oh wow there’s so much to consider when mixing ingredients. Chemists have to develop a forumla that is stable, doesn’t irritate skin, smells pleasant, all with an appealing consistency! I always think of sulfates when it thinking of ingredients that help water and oil mix.
