Claim:
A fragrance precursor compound comprising one or more of the compounds derived from the reaction of X—OH and an aldehyde or ketone, said fragrance precursor compounds being of the formula X—O—C(R)(R*)(R**) wherein R is a C 6-24 alkyl group, a C 6-24 aralkyl group or a C 6-24 alkaryl group; R* is H or a C 6-24 alkyl group, a C 6-24 aralkyl group or a C 6-24 alkaryl group; R** is O—H or O—X; O—X representing a moiety derived from X—OH, and wherein X—OH is a material containing at least one hydroxyl group chosen from surfactants containing at least one hydroxyl group, fabric softener materials containing at least one hydroxyl group, softener precursor ester amines containing at least one hydroxyl group, softener precursor amido amines containing at least one hydroxyl group, hair conditioners containing at least one hydroxyl group, skin conditioners containing at least one hydroxyl group, saccharides, and polymers containing at least one hydroxyl group; wherein X—OH is of the following structure: wherein R 1 and R 2 are each independently, H or: (a) C 1 -C 22 alkylenecarboxy moiety having the formula: —(CH 2 ) e R 3 wherein R 3 is —NHCOR 4 ; or —OCOR 4 ; or —NR 5 COR 4 ; and wherein R 4 and R 5 are each independently C 1 -C 22 akyl or alkenyl; and e is an integer from 1 to 22; or (b) C 1 -C 22 linear or branched alkyl; or (c) C 1 -C 22 linear or branched alkenyl; or (d) C 2 -C 22 substituted or unsubstituted alkylenoxy; or (e) C 3 -C 22 substituted or unsubstituted alkylenoxy alkyl; or (f) C 6 -C 22 substituted or unsubstituted aryloxy; or (g) C 7 -C 22 substituted or unsubstituted alkylenearyl; or (h) C 7 -C 22 substituted or unsubstituted alkyleneoxyaryl; or (i) C 7 -C 22 oxyalkylenearyl; or (j) a unit having the formula: —(CH 2 ) y R 6 wherein R 6 is —SO 3 M, —OSO 3 M, —PO 3 M, —OPO 3 M, Cl or combinations thereof, wherein M is hydrogen, or one or more salt forming cations sufficient to satisfy charge balance, or combinations thereof; y is an integer from 1 to about 22; and (k) a combination comprising at least two of (a) through (j); and q is an integer from 0 to about 22; m is an integer from 0 to about 22; Q is (CH 2 ) or (CH 2 CHR 7 O); R 7 is independently hydrogen, methyl, ethyl, propyl or benzyl; and combinations thereof; B is OH; Y is N; R 8 is H or C 1 -C 4 alkyl; Z − is a counter anion.
