A microcapsule system having an outer microcapsule with an outer capsule shell is disclosed. The outer microcapsule comprises at least one inner microcapsule with an inner capsule shell and a first fragrance composition. The inner microcapsule comprises a second fragrance composition that differs from the first fragrance composition. Methods for the production of such micr, products that contain said microcapsules, methods for producing polysensory olfactory impressions and to the corresponding use of the microcapsule system.

Microcapsule system for polysensory olfactory effects I

A compound based on 1-Aza-3,7-dioxabicyclo[3.3.0]octane (bicyclic oxazolidine derivative) substituted with 3-(4-isobutyl-2-methylphenyl)propyl represented by formula (I) is disclosed.

Pro-fragrances and method of preparation thereof

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

Bad odors on textile materials are often caused by body odor. The invention relates to a textile material treatment method for inhibiting body odor on textile materials, by which means the treated textiles, after having been worn, even after sweat-inducing sports activities, have a significantly reduced bad odor or even no odor. The invention also relates to a perfume composition and to a textile material treatment agent, respectively comprising urea derivatives and/or phenacylthiazolium salts, that counteract the formation of body odor.
