What it is
Terpineol refers to a group of closely related monoterpene alcohol isomers, with alpha-terpineol being the most common, valued for its pleasant floral, lilac-like scent. In cosmetics it is used to impart or round out fragrance and can also serve as a solvent. It occurs naturally in many essential oils, including pine and certain citrus and tea tree oils.
Safety & warnings
Terpineol is a fragrance material and can be a source of sensitization or irritation in fragrance-sensitive individuals, particularly if oxidized. Like many terpenes it can degrade on exposure to air and light, and oxidation products may increase irritation potential. Those avoiding fragrance ingredients may wish to note its presence.
Origin & sourcing
Found naturally in numerous essential oils such as pine and cajuput; it is also produced synthetically, often from turpentine-derived pinene, for consistent fragrance-grade material.
