Washing or cleaning agents are described which contain reaction products of odorants with metal oxides, such as for example ZnO, ZrO, FeO, FeO, AlO, TiO, CeOand/or SnO. The reaction products are preferably produced separately and subsequently added to the washing or cleaning agent matrix. These washing or cleaning agents bring about advantages when fragrancing objects, such as for example textiles. In particular, they make it possible to achieve targeted scent release by remoistening the treated object.

Detergents or cleaning agents containing reaction products of odorants with metal oxides

Unsaturated ketones of general formula (I) where the groups R1, R2, R3, R4 and R5 independently=H or 1-6 C alkyl groups, which can be saturated or unsaturated, straight-chained, branched or cyclic are characterised by an interesting and original odour characteristic with good emanation and are suitable for use as perfumes, for example in cosmetic preparations, technical products or alcoholic perfumery.

Use of unsaturated ketones as a perfume

The invention relates to hexenal derivatives of general structure (I), in which one of the bonds represented by dashes is a C&#x2014;C single bond and the other is a C&#x2550;C double bond, with the proviso that the C&#x2550;C double bond can have a Z or E configuration, provided that it is in the C&#xbe; position. Said derivatives are characterised by an interesting and original perfume that pervades a wide area and are suitable for use as perfumes, for example in cosmetic preparations, technical products or the alcohol-based perfume industry.
