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.
