About

A secondary alcohol with a mild, earthy, mushroom-like odor used as a fragrance ingredient and solvent in cosmetic formulations.

2-Octanol (capryl alcohol, sec-caprylic alcohol) is a secondary alcohol functioning as a fragrance ingredient and solvent. It is not listed in EU Annexes II or III and has low acute oral and dermal toxicity. The compound occurs naturally in some essential oils and has been assessed by IFRA as safe in fragrance compositions. It has a characteristic odor described as earthy, mossy, or mushroom-like at low concentrations. Like other fatty alcohols, it is metabolized and eliminated without significant bioaccumulation, presenting minimal systemic toxicity concern.
