About

A floral-spicy fragrance ingredient related to linalool, carrying the same potential for skin sensitization as other linalool derivatives.

Isobutyl linalool is a tertiary alcohol related to linalool, used as a fragrance ingredient providing floral, lavender-like notes. It is listed in EU CosIng. Like linalool, it may undergo autoxidation forming oxidation products that are known contact allergens. The EU requires allergen declaration for linalool and related compounds. IFRA standards restrict its use to reduce sensitization risk from oxidation products.
