PERFUME COMPOSITIONS

摘要

Perfume compositions comprise at least 50% by weight of ingredients characterized by (i) having a molecular formula possessing from 8 to 13 carbon atoms, none of which form part of phenyl moieties, substituted or unsubstituted; (ii) an octanol/water partition coefficient (logP) of at least 2; (iii) a saturated vapour pressure (SVP) of at least 5 micron Hg at 25°C; and (iv) belonging to one of the following groups: 1) ethers of general formula R₁OR₂; 2) aldehydes or nitriles R₁X, wherein X is a formyl group or a cyano group; 3) esters R₁CO₂R₂; 4) alcohols R₁OH; 5) ketones R₁COR₂; wherein R₁ and R₂ are hydrocarbyl residues, straight chain or branched, and optionally substituted, and may be linked as part of a ring structure. The compositions find particular application in the form of encapsulates for use in consumer products.
