Undecyl Alcohol
What Undecyl Alcohol is & what it does
Undecyl Alcohol is a fatty alcohol with an eleven-carbon chain, used in cosmetics chiefly as an emollient, fragrance component, and viscosity or texture modifier. Unlike volatile drying alcohols, fatty alcohols of this type help give products a smooth, conditioned skin feel and can support emulsion stability. It is typically used at low levels within a broader formula. It is not a UV filter and contributes no sun protection.
