About A-TERPINYL ACETATE
A naturally occurring monoterpene ester found in lavender and other essential oils, used as a fragrance material with mild sensitization potential.
Detailed Analysis
alpha-Terpinyl acetate is a monoterpene ester constituent of many essential oils including lavender (Lavandula angustifolia), tea tree, and cardamom. It is widely used as a fragrance material in perfumes, cosmetics, and household products. The compound is classified under IFRA standards as having mild sensitization potential at high purity levels. Under EU Regulation 1223/2009 Annex III, certain fragrance allergens must be labeled; terpinyl acetate itself is not a declared allergen at typical usage levels, but linalool and other oxidation products of terpene materials may trigger labeling requirements. The compound has a long history of safe use in the fragrance industry with a PubChem safety score of 80.
