Perfume compositions comprise over 50% by weight of perfume ingredients characterized by possessing (i) a molecular formula possessing from 8 to 13 carbon atoms, including at least one phenyl moiety, substituted or unsubstituted; (ii) an octanol/water partition coefficient (log P) of at least 1.5; (iii) a saturated vapour pressure (SVP) of at least 3 micron Hg at 25 C; and (iv) belonging to one of the following groups (i) ethers of general formula R1OR2; (ii) aldehydes or nitriles of general formula RIX, wherein X is CHO (formyl group) or CN (cyano group); (iii) esters of general formula R1CO2R2; (iv) alcohols or phenols of general formula R1OH; or (v) ketones of general formula R1COR2; wherein R1 and R2 are alkyl, aryl, aralkyl or alkaryl residues, optionally substituted, whose alkyl moieties may be straight-chained or branched, and which may be linked as part of a ring structure. The compositions find particular application in the form of encapsulates for use in consumer products. |
