A detergent, cleaning, fabric softener or cosmetic composition comprising a compound based on 1-Aza-3,7-dioxabicyclo[3.3.0]octane (bicyclic oxazolidine derivative) substituted with 3,7-dimethyl-1,6-nonyldien represented by formula (I) is disclosed.

Composition comprising precursor for volatiles

Stable formulations and perfume compositions include amino alcohol(s) as well as &#x3e;10 wt % fragrances.

Stabilized perfume oils

The invention relates to a composition of (a) a selected amino alcohol compound of general formula (I), (b) a scent aldehyde and/or scent ketone, and (c) a selected silicic acid ester, to the use of same as a pro-scent, as well as to washing and cleaning agents, fabric softeners and cosmetics which contain these. The invention also relates to a method for prolonging the perception of scent in such agents, and to a method for removing malodors by applying said composition. 

Combination of an amino alcohol, a fragrance and a silicic acid ester, and the use of same as a pro-fragrance

The invention relates to combinations of 1-aza-3,7-dioxabicyclo[3.3.0]octane compounds with silicic acid esters, methods for producing same, the use of same as pro-fragrances, as well as washing and cleaning agents, fabric softeners and cosmetics that contain same. The invention also relates to a method for prolonging the perception of fragrance in such agents.

Combinations of 1-aza-3,7-dioxabicyclo[3.3.0]octane compounds and silicic acid esters and the use of same as pro-fragrances

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.
