CONSUMER PRODUCTS CONTAINING PRO-FRAGRANCES

摘要

The invention relates to novel liquid compositions, comprising: a) a liquid base intended for the treatment of surfaces, in particular fabrics or hard surfaces; b) at least one sulfur-containing compound of formula wherein R1 and R2 represent, separately and independently of each other, a hydrogen atom, a halogen atom, preferably chlorine, a C1-C4 linear or branched alkyl group, an amino group or a benzylamino group; or, alternatively, R1 and R2 are taken together to represent a phenyl or pyridine ring, possibly substituted with one to four C1-C4 linear or branched alkyl or alkenyl groups and/or one to two halogen atoms, preferably chlorine atoms; and R3 represents a hydrogen atom, an alkali metal atom, in particular Na or k, a phenyl or benzyl group possibly substituted with one or two halogen atoms and/or one or two methyl, trifluoromethyl, methoxy or amino groups, an amine group, or a C1-C8 unsaturated, linear, branched or cyclic hydrocarbon group possibly substituted with one or two nitrogen, oxygen or halogen atoms; c) at least one sulfur-containing pro-fragrance compound; and d) one or more perfuming co-ingredients; and wherein the composition has a pH comprised between 1 and 8. The compositions can be advantageously used in methods of treatment of fabric and household surfaces, to impart thereto a fresh, odor stable and long-lasting fragrance. They also show a stable out of the bottle odor, without any off-odor notes, independently of the duration of storage of the bottled liquid products.
