The deliberate release of odorants or aroma substances is desirable in many fields of application, and in particular in the field of washing and cleaning agents. Said deliberate release is achieved by using an odorant composition that comprises an odorant precursor, which is an allyl ether of the formula (I), R

mutually independently denote H or a hydrocarbon residue that can be acyclic or cyclic, substituted or unsubstituted, branched or unbranched, as well as saturated or unsaturated. Thus, in particular odorants in the form of an alkene having an allylic hydrogen atom, such as α-pinene, can be released in a deliberate manner.
有意识地释放气味物质或香气物质在许多应用领域中是可取的,特别是在洗涤和清洁剂领域中。通过使用包含气味前体的气味组成物,实现了上述有意识的释放,其中所述气味前体是公式(I)的丙烯醚,R1R2C═CR3—CR4R5—O—CHR6R7,其中残基R1,R2,R3,R4,R5,R6和R7相互独立地表示H或可以是无支链或支链的饱和或不饱和的脂肪烃残基,以及替代或未替代的环烷基。因此,特别是可以有意识地释放具有烯丙基氢原子的烯烃形式的气味物质,例如α-蒎烯。
