Abstract

Washing or cleaning agents are described which contain reaction products of odorants with metal oxides, such as for example ZnO, ZrO2, Fe2O3, Fe3O4, Al2O3, TiO2, CeO2 and/or SnO2. 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.
