Abstract:
A laundry detergent composition having increased fragrance retention and fragrance longevity on fabric, comprising:A) at least 0.01% by weight, of a fragrance delivery system comprising:i) one or more orthocarbonate pro-fragrances having the formula: ##STR27##wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently C.sub.1 -C.sub.20 linear, branched, or substituted alkyl; C.sub.2 -C.sub.20 linear, branched, or substituted alkenyl; C.sub.5 -C.sub.20 substituted or unsubstituted cyclic alkyl; C.sub.6 -C.sub.20 substituted or unsubstituted aryl, C.sub.2 -C.sub.40 substituted or unsubstituted alkyleneoxy; C.sub.3 -C.sub.40 substituted or unsubstituted alkyleneoxyalkyl; C.sub.6 -C.sub.40 substituted or unsubstituted alkylenearyl; C.sub.6 -C.sub.40 substituted or unsubstituted aryloxy; C.sub.6 -C.sub.40 substituted or unsubstituted alkyleneoxyaryl; or two R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are taken together to form a ring having from 5 to 7 atoms wherein said ring is substituted or unsubstituted; provided:a) one R.sup.1, R.sup.2, R.sup.3, or R.sup.4 comprises a fragrance raw material having a molecular weight greater than or equal to 100 g/mol;b) said orthocarbonate pro-fragrance has a molecular weight greater than or equal to 300 g/mol;ii) optionally one or more pro-fragrance materials selected from the group consisting of acetals, ketals, orthoesters, orthophosphates, orthosilicates, and mixtures thereof;iii) optionally one or more fragrance raw materials;B) at least 0.01% by weight, of a detersive surfactant selected from the group consisting of anionic, cationic, nonionic, zwitterionic, ampholytic surfactants, and mixtures thereof; andC) the balance carriers and adjunct ingredients.
