About

Methyl Linalool is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Methyl linalool is a naturally occurring and synthetically produced monoterpene alcohol used extensively in fragrance compositions across cosmetic categories. While not subject to EU Annex III restrictions, IFRA imposes concentration limits due to its potential for skin sensitisation. Linalool rapidly oxidises on air exposure, forming hydroperoxides that are the primary sensitisers, and EU cosmetic regulations require declaration of oxidation products.

Known concerns

  • Skin sensitiser (IFRA restricted)
