Abstract:
A fragrance precursor composition, comprising an organoleptically effective amount of at least one compound of the formula ##STR6##whereinX is O or S;m is 0, 1 or 2, and n is 1-20;R.sup.1 is the radical of an alcohol R.sup.1 OH or a mercaptan R.sup.1 SH having more than five carbon atoms;R.sup.2 is the radical of an alcohol R.sup.2 OH or a mercaptan R.sup.2 SH having more than five carbon atoms; orif R.sup.2 is a substituted or unsubstituted C.sub.6-40 -alkyl or C.sub.6-40 -alkenyl radical, a carbocyclic radical or an aromatic radical, then R.sup.2 may in addition contain one or more hetero atoms, --COOR.sup.5 and groups ##STR7##which groups may further be substituted by --COOR.sup.5, wherein R.sup.5 is the radical of an alcohol R.sup.5 OH or a mercaptan R.sup.5 SH having more than five carbon atoms, orR.sup.2 is a polyalcohol radical or a sugar radical, of which one or more of the hydroxyl functions may be substituted as carbonates containing R.sup.1 and/or R.sup.2 ;wherein at least one of R.sup.1 OH, R.sup.1 SH, R.sup.2 OH, R.sup.2 SH, R.sup.5 OH and R.sup.5 SH has fragrance properties;R.sup.3 and R.sup.4 are H or C.sub.1-6 alkyl orR.sup.3 and R.sup.4 form a carbocyclic or heterocyclic ring,with the exception of carbonic acid 4-allyl-2-methoxy-phenyl ester benzyl ester, in a cosmetically acceptable carrier, wherein the, precursor is odorless.
