Compounds of the formula ##STR1## wherein R.sup.1 is C.sub.1-5 alkyl, R.sup.2 is selected from hydrogen and C.sub.1-5 alkyl, X is selected from hydrogen and --COR.sup.3 wherein R.sup.3 is selected from hydrogen and C.sub.1-6 alkyl are useful in room freshners and other compositions for counteracting malodors in air, wherein the malodors are caused by one or more compounds selected from lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines and arsines. The defined compounds impart little or no fragrance to such compositions but the compositions may include additional fragrances. Particularly valuable and novel compounds are those wherein R.sup.1 is methyl, R.sup.2 is selected from hydrogen and methyl and X is --COR.sup.3 wherein R.sup.3 is C.sub.2-6 alkyl.
A method of counteracting a malodor in the air caused by a compound selected from the group consisting of lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines and arsines which comprises introducing into the air an effective malodor counteracting amount of cyclohexyl- 1-ethyl-n-butyrate whereby the perceived total odour intensity in the air is reduced and the perceived malodor intensity in the air is substantially eliminated.
A method of counteracting a malodor in the air caused by a compound selected from the group consisting of lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines and arsines which comprises introducing into the air an effective malodor counteracting amount of cyclohexyl-1-ethyl acetate whereby the received total odour intensity in the air is reduced and the perceived malodor intensity in the air is substantially eliminated.
A method of counteracting a malodor in the air caused by a compound selected from the group consisting of lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines and arsines which comprises;
A method according to claim 8 in which R.sup.3 is selected from the group consisting of hydrogen and C.sub.1-3 alkyl, R.sup.1 is methyl and R.sup.2 is selected from the group consisting of hydrogen and methyl.
