What is 2-Octanol?

2-Octanol (CAS 6169-06-8) is a secondary aliphatic alcohol used as a solvent and carrier in pharmaceutical and personal care manufacturing.

Where is 2-Octanol used?

  • Pharmaceutical manufacturing: process solvent for active ingredient extraction and purification
  • Personal care: carrier solvent in fragrance systems and emollients
  • Skin-conditioning preparations: improves ingredient dispersion and skin feel
  • Synthesis of esters and other specialty chemicals for cosmetic supply chains
  • In topical formulation development its slower evaporation rate compared to short-chain alcohols supports controlled delivery.

Good to know: Preferred where primary alcohols are too aggressive or volatile. Buyers should confirm optical purity requirements when sourcing.
