Claim:
A perfume composition comprising over 60% by weight of perfume ingredients that are characterized by (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 expressed as a log to the base 10 (log P) of at least 1.5; (iii) a saturated vapour pressure (SVP) of at least 3 micron Hg at 25° C.; and (iv) membership of one of the following groups: 1. ethers of general formula R 1 OR 2 ; 2. aldehydes or nitriles of general formula R 1 X, wherein X is CHO (formyl group) or ON (cyano group); 3. esters of general formula R 1 CO 2 R 2 ; 4. alcohols or phenols of general formula R 1 OH; or 5. ketones of general formula R 1 COR 2 wherein R 1 and R 2 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; provided that (a) the perfume ingredients do not include essential oils or components thereof; (b) where a perfume ingredient could be assigned to more than one of the above groups, said ingredient is allocated to the group having the lower or lowest number; (c) any components used as non-odorous or very low odour diluents, solvents or vehicles of the perfume composition are not included in the calculation of the percentage composition; and (d) at least three of the groups (1) to (5) must each comprise perfume ingredients amounting to at least 5% by weight of the perfume composition.
