About
A secondary alcohol with mild solvent properties used as a fragrance ingredient and processing aid in cosmetic formulations.
2-Pentanol (sec-amyl alcohol) is a secondary alcohol functioning as a fragrance ingredient and solvent in cosmetic formulations. It is not listed in EU Annexes II or III and presents low acute toxicity. Simple alcohols like 2-pentanol are metabolized through pathways similar to ethanol and are rapidly eliminated from the body, reducing systemic toxicity concerns. It may contribute to the overall fragrance profile of a product at low concentrations and functions as a processing solvent for certain cosmetic ingredients.
