About
A branched aliphatic alcohol used as a fragrance ingredient or solvent, contributing fatty, green, and slightly floral notes to cosmetic formulations. The branched structure reduces skin penetration compared to linear analogs.
3-Methylpentan-1-ol is a branched-chain aliphatic alcohol (C6) with the methyl substituent at position 3. The branching pattern creates a tertiary carbon at C3 and primary alcohol at C1, influencing both odor properties and skin interaction. It is not listed in EU Annex II (banned substances) or Annex III (restricted substances) of the Cosmetics Regulation. The branched aliphatic structure typically presents lower skin penetration than linear chains, and the short chain length (C6) limits lipophilicity and potential for accumulation.
