DIHYDROLANOSTEROL

Safety grade: A

Dihydrolanosterol is a waxy, fat-like substance derived from lanolin (a natural oil found in sheep's wool) that helps keep cosmetic products from separating. It works similarly to how oil and vinegar need an emulsifier to stay mixed together in salad dressing.

This ingredient helps bind oil and water together in cosmetic formulations, stabilizes emulsions to prevent separation, and conditions the skin by forming a protective moisturizing layer.
