    • 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 R 1 and R 2 represent, separately and independently of each other, a hydrogen atom, a halogen atom, preferably chlorine, a C 1 -C 4 linear or branched alkyl group, an amino group or a benzylamino group; or, alternatively, R 1 and R 2 are taken together to represent a phenyl or pyridine ring, possibly substituted with one to four C 1 -C 4 linear or branched alkyl or alkenyl groups and/or one to two halogen atoms, preferably chlorine atoms; and R 3 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 C 1 -C 8 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.
    • 本发明涉及新的液体组合物,其包括:a)用于处理表面,特别是织物或硬表面的液体基料; b)至少一种下式的含硫化合物,其中R 1和R 2彼此独立地且独立地表示氢原子,卤素原子,优选氯,C 1 -C 4直链或支链烷基,氨基或 苄基氨基; 或者可选地,R 1和R 2一起表示苯基或吡啶环,其可以被一至四个C 1 -C 4直链或支链烷基或烯基和/或一至两个卤素原子,优选氯原子取代; R 3表示氢原子,碱金属原子,特别是Na或k,可被一个或两个卤素原子和/或一个或两个甲基,三氟甲基,甲氧基或氨基取代的苯基或苄基,胺基, 或可被一个或两个氮,氧或卤原子取代的C1-C8不饱和的,直链的,支链的或环状的烃基; c)至少一种含硫的前香料化合物; 和d)一种或多种加香配料; 并且其中所述组合物具有1至8的pH。所述组合物可有利地用于处理织物和家庭表面的方法,赋予其新鲜,气味稳定和持久的香味。 它们还显示出瓶子气味中的稳定性,而没有任何异味的音符,与瓶装液体产品的储存持续时间无关。
