This invention relates to odor neutralizers comprising esters of the formula (I) wherein R.sup.1 is an alkyl radical with 1 to 4 carbon atoms which can optionally contain a double bond; R.sup.2 is a hydrogen or an alkyl radical with 1 to 3 carbon atoms which can optionally contain a double bond; R.sup.3 is a hydrogen or a methyl radical substituted by the alkyl radicals R.sup.9 and R.sup.10; R.sup.4 is a hydrogen, a methyl radical or an acyloxy radical of the general formula O--CO--R.sup.1 wherein R.sup.1 has the abovementioned meaning; R.sup.5, R.sup.6, R.sup.7, R.sup.8 and R.sup.10 are identical or different and is hydrogen or methyl; R.sup.9 is a hydrogen and R.sup.4 and R.sup.9 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 R.sup.1=methyl, R.sup.2=isopropyl, R.sup.5=methyl and R.sup.6=hydrogen, the substituents R.sup.2 and R.sup.5 are arranged in a cis relationship to each other; ii) in the case of cyclohexyl esters in which R.sup.2=isopropenyl, R.sup.5=methyl and R.sup.6=hydrogen, the substituent R.sup.1 is an alkyl group with at least two C atoms; iii) in the case of acyclic monofunctional esters, the substituent R.sup.1 is an alkyl group with at least two C atoms; and iv) in the case of cyclohexyl esters in which R.sup.2, R.sup.7, R.sup.8=hydrogen and R.sup.5, R.sup.6, R.sup.10=methyl, the substituent R.sup.1 is methyl, ethyl, propyl or 1-propen-1-yl.
