Decyl Glucoside

Decyl glucoside — from coconut-derived C10 alcohol and glucose — is one of the gentlest widely used surfactants, forming the backbone of "no-tears" baby washes and sensitive-skin cleansers. It foams modestly, cleanses effectively at pH ~5.5–7, and has an exemplary irritation record even at high concentration. At 8–30% it suits daily facial cleansing including around the eyes. Its only weaknesses: modest foam density and slight stickiness of raw material — irrelevant in finished products. When a cleanser claims "gentle" and lists decyl glucoside early, the claim is credible. Combine with coco-glucoside and glutamates for complete mild systems.
