About
A branched-chain fatty alcohol with a mild, waxy, citrus-like odor used as a fragrance ingredient and emollient in cosmetic products.
2-Methylundecanol is a branched-chain primary fatty alcohol functioning as a fragrance ingredient and emollient. The methyl branch at the 2-position provides increased oxidative stability compared to linear fatty alcohols. It is not listed in EU Annexes II or III. Fatty alcohols are generally recognized as safe in cosmetics, with low irritation potential and favorable environmental profile. The branched structure differentiates it from more common fatty alcohols like cetearyl or stearyl alcohol, adding unique odor characteristics while maintaining the favorable safety profile typical of the fatty alcohol class.
