The present invention relates to depot preparations for the targeted release of an aldehyde together with two carboxylic acids, where the released aldehydes are organoleptic substances, specifically fragrances or flavorings, and these depot preparations are prepared by reacting aldehydes with carboxylic anhydrides.

Depot preparations

The present invention relates to novel mixtures of macrocyclic musk fragrances, the use of these mixtures in fragrance compositions and perfumed products containing these mixtures.

Mixtures for use as musk fragrance

This invention relates to odor neutralizers comprising esters of the formula (I) wherein Ris an alkyl radical with 1 to 4 carbon atoms which can optionally contain a double bond; Ris a hydrogen or an alkyl radical with 1 to 3 carbon atoms which can optionally contain a double bond; Ris a hydrogen or a methyl radical substituted by the alkyl radicals Rand R; Ris a hydrogen, a methyl radical or an acyloxy radical of the general formula O&#x2014;CO&#x2014;Rwherein Rhas the abovementioned meaning; R, R, R, Rand Rare identical or different and is hydrogen or methyl; Ris a hydrogen and Rand Rcan together represent a single carbon bond or a methylene or an ethylene bridge,with the proviso that i) in the case of cyclohexyl esters in which R=methyl, R=isopropyl, R=methyl and R=hydrogen, the substituents Rand Rare arranged in a cis relationship to each other; ii) in the case of cyclohexyl esters in which R=isopropenyl, R=methyl and R=hydrogen, the substituent Ris an alkyl group with at least two C atoms; iii) in the case of acyclic monofunctional esters, the substituent Ris an alkyl group with at least two C atoms; and iv) in the case of cyclohexyl esters in which R, R, R=hydrogen and R, R, R=methyl, the substituent Ris methyl, ethyl, propyl or 1-propen-1-yl.

Odor neutralizers

The compound (Z)-7-cyclohexadecen-1-one is described as a musk odorant. Also described are odorant or aroma mixtures comprising (Z)-7-cyclohexadecen-1-one and one or more other odorants or aromas.

(Z)-7-cyclohexadecen-1-one as an odorant

Matrix particles having a perfume component and washing-active surfactant component can be used in body-cleansing compositions and housecleaning products.

Care gents

A mathematical determination model is used to select odorants for products to be perfumed and for the preparation.

Selection method for odorants

Multiphase soaps in which the individual phases are highly visible when viewed from above and from the side have high stability. Their use permits various scent experiences to be achieved during the washing operation.

Care agents based on matrix particles having a perfume component and washing-active surfactant components can be used in body-cleansing compositions and household cleaners.

Care agents

Certain 2-carbonylbenzofurans and 2-carbonyl-2,3-dihydrobenzofurans are excellent odoriferous substances.

Use of substituted 2-acetylbenzofurans as odoriferous substances

Ethylvanillin isobutyrate is a valuable new fragrance and flavor substance which, because of its extraordinary organoleptic profile and its favorable technical properties, permits hitherto unknown effects in perfumery and flavoring.
