About

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.
