Gamma-Decalactone
What is Gamma-Decalactone?
Gamma-Decalactone, also called 5-hexyloxolan-2-one, is a synthetic gamma-lactone, a type of cyclic ester with a molecular formula C10H18O2. It occurs naturally in some fruits but is produced commercially for its sweet, fruity scent evoking peaches, apricots, and coconut cream. In cosmetics, it functions exclusively as a fragrance ingredient, imparting characteristic aroma notes that define a product's sensory identity. It blends seamlessly into formulations like lotions, creams, shampoos, and perfumes, typically at trace levels to enhance appeal and cover base odors from active components. Regulatory bodies affirm its use within defined limits, with evaluations confirming low skin penetration and minimal reactivity. Its colorless, oily liquid form ensures stability in emulsions and anhydrous products, supporting diverse application formats without altering texture.
