  • Applications

    gamma-OCTADECALACTONE is used primarily as an aroma compound in perfumery (fruit-like notes) and as a flavor ingredient in foods, and also as a fragrance component in cosmetics and personal care; in household products such as cleaners and air fresheners, it acts as an odorant and aroma contributor; in polymer systems and coatings it is used as a fragrance additive for plastics and coatings; it may also serve as an industrial intermediate or building block for the synthesis of other aroma compounds in manufacturing. Subject to local regulations and formulation limits.
