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.
Decyl Glucoside is generally considered to be safe.
