    • The invention relates to fragrance precursors, In particular, the invention relates to the use of several classes of compounds which may act as fragrance precursors, e,g., in cosmetic products such as deodorants and antiperspirants and in laundry products such as detergents and fabric softners. These compounds are odorless, but upon contacting the skin as example, in skin care compositions or in personal care compositions, produce fragrances. The compounds also produce fragrances when used in the presence of lipases, e.g. as used in (laundry) detergents, thus providing a prolongation of the fabric scenting effect. The compounds under consideration are compounds of the formula I: The substituents are defined in the specification.
    • 本发明涉及香料前体。特别地,本发明涉及可用作香料前体的几类化合物的用途,例如在化妆品中,例如除臭剂和止汗剂,以及洗涤产品如洗涤剂和织物 软体 这些化合物是无味的,但是例如在皮肤接触皮肤护理组合物或个人护理组合物中时,产生香料。 当在脂肪酶存在下使用时,这些化合物也产生香料。 如(洗衣)洗涤剂中使用的那样,从而延长了织物的香味效果。 所考虑的化合物是式I的化合物:取代基在说明书中定义。
