摘要:
This invention relates to odor neutralizers comprising esters of the formula (I) wherein R1 is an alkyl radical with 1 to 4 carbon atoms which can optionally contain a double bond; R2 is a hydrogen or an alkyl radical with 1 to 3 carbon atoms which can optionally contain a double bond; R3 is a hydrogen or a methyl radical substituted by the alkyl radicals R9 and R10; R4 is a hydrogen, a methyl radical or an acyloxy radical of the general formula O—CO—R1 wherein R1 has the abovementioned meaning; R5, R6, R7, R8 and R10 are identical or different and is hydrogen or methyl; R9 is a hydrogen and R4 and R9 can 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 R1=methyl, R2=isopropyl, R5=methyl and R6=hydrogen, the substituents R2 and R5 are arranged in a cis relationship to each other; ii) in the case of cyclohexyl esters in which R2=isopropenyl, R5=methyl and R6=hydrogen, the substituent R1 is an alkyl group with at least two C atoms; iii) in the case of acyclic monofunctional esters, the substituent R1 is an alkyl group with at least two C atoms; and iv) in the case of cyclohexyl esters in which R2, R7, R8=hydrogen and R5, R6, R10=methyl, the substituent R1 is methyl, ethyl, propyl or 1-propen-1-yl.

摘要:
The use of 4,8-dimethyl-7-nonen-2-one and 4,8-dimethylnonan-2-one as fragrances with a rose odour is described. Corresponding perfume compositions, perfumed products and processes for producing or strengthening a rose odour are also described.
摘要:
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.
摘要:
The present invention primarily concerns teeth cleaning compounds containing menthol for use with a toothbrush, preferably tooth pastes, tooth crèmes, tooth cleaning gels or tooth powders. Such a tooth cleaning compound according to the invention contains menthol and a quantity, for masking the bitterness of the menthol, of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) of the following formula (Ia), in particular of the following formula (Ib), i.e. L-menthane carboxylic acid-N-(4-methoxyphenyl)-amide. The present invention also concerns the use of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) of the formulas (Ia) or (preferably) (Ib) to mask the bitter taste of menthol in a teeth cleaning compound.The present invention also concerns a method for dissolving menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) in a teeth cleaning compound and a method for masking the bitterness of menthol in a teeth cleaning compound.
摘要:
Compounds of formula (A) are described wherein, independently of one another, the following applies to groups R and R1: R is methyl or ethyl, and R1 is hydrogen or methyl, wherein the meandering line shows that for R1=methyl, the associated double bind is (E)- or (Z)-configured. Furthermore, methods for producing compounds of formula (A) and the use of corresponding compounds as fragrance and/or flavouring substances are described.
