Science & Benefits
A fatty alcohol that stabilizes emulsions. Similar to Cetyl Alcohol, it is safe but can be occlusive in high concentrations. Its primary risk is synergistic; when combined with certain emulsifiers (like Ceteareth-20), its comedogenic potential increases significantly. In an acne-safe database, it's best suited for dry-acne types or in rinse-off products.
