About
An unsaturated fatty acetate (C6) with a green, fruity aroma used in cosmetics — the double bond requires antioxidant preservation to prevent oxidative degradation.
Hexenyl Acetate (cis-3-hexenyl acetate, C6 unsaturated) is a green-note unsaturated fatty acetate with a fresh cut-grass and apple aroma. It occurs naturally in green leaves and fruits. The double bond at position 3 means the compound can oxidise over time, forming potential sensitisers (similar to linalool). IFRA guidelines recommend antioxidant preservation for this class of compound. When properly preserved, the sensitisation risk is well-controlled. Listed in CosIng without specific restrictions.
