Chemistry, Properties & Perfumer Guide
The Chemistry
Alcohols, C11-14-iso-, C13-rich is a synthetic mixture of branched-chain fatty alcohols with a predominance of C13 isomers. These alcohols are produced through hydroformylation of olefins followed by hydrogenation, creating a distribution of iso-alcohols. The branched structure provides different physical properties compared to their straight-chain counterparts, including altered solubility and boiling characteristics. The ‘C13-rich’ designation indicates the mixture is enriched with 13-carbon chain length alcohols, though it contains a distribution of chain lengths from C11 to C14.
