Abstract
The present disclosure relates to the field of malodour counteraction. More particularly, it concerns compositions that limit, decrease or eliminate the perception of malodours associated with soaps or soap bases. Such compositions include (i) a malodour antagonist system associated with perfuming ingredients performing as malodour counteractant, and (ii) at least one malodour neutralizing system, in a combination that significantly reduces the perception of malodours associated with soaps or soap bases. Such compositions, their use in combination with delivery systems and their applications in consumer products are objects of the present disclosure.
Claims2
A method of reducing a perception of raw material malodor in a soap base, the method comprising adding to the soap base a malodor counteracting composition,
- wherein the malodor counteracting composition comprises (i) a malodor antagonist composition, which comprises at least one compound that inhibits the activity of at least one olfactory receptor selected from the group consisting of:
- a DMTS olfactory receptor, an indole/skatole olfactory receptor, a butyric acid olfactory receptor, and a p-cresol olfactory receptor, and (ii) a malodor neutralizing composition,
- wherein the malodor counteracting composition is added to the soap base at a concentration ranging from 0.005 to 0.1 wt %, relative to the weight of soap base, and
- wherein the malodor neutralizing composition comprises:
- (a) at least one ingredient selected from the group consisting of:
- (i) at least one aldehyde of formula R1CHO, wherein R1 is an aliphatic linear or branched, saturated or unsaturated carbon chain containing from 1 to 12 carbon atoms;
- (ii) at least one ketone of formula R2COR3, wherein R2 is an ethyl or methyl group and R3 is an aliphatic linear or branched, saturated or unsaturated carbon chain containing from 1 to 12 carbon atoms;
- and (iii) at least one primary alcohol of formula R4CH2OH, wherein R4 is an aliphatic linear or branched, saturated or unsaturated carbon chain containing 1 to 12 carbon atoms, optionally substituted with an aromatic moiety;
- (b) at least one ingredient selected from the group consisting of α-damascone, β-damascone, γ-damascone, δ-damascone, α-neobutenone, (+)-methyl-2,2-dimethyl-6-methylene-1-cyclohexanecarboxylate, α- or β-(E)-4-(2,6,6-trimethyl-2-cyclohexen-1-yl}-3-buten-2-one (α- or β-ionone), α-methyl-ionone, β-methyl-ionone, γ-methyl-ionone, 1-(2,6,6-trimethyl-1 (2)-cyclohexen-1-yl)-1,6-heptadien-3-one and 1-(4,6,6-trimethyl-1,3-cyclohexadien-1-yl}-2-buten-1-one;
- and
- (c) at least one nitrile ingredient selected from the group consisting of 3-phenyl-2-propenenitrile, citronitrile, citronellyl nitrile, 2-propyl-1-heptanenitrile, dodecanenitrile, and the mixture of 3-(2,3-dimethyl-2 (3)-cyclopenten-1-yl) butanenitrile and 3-(2-methyl-3-methylene-1-cyclopentyl) butanenitrile;
- wherein the malodor antagonist composition is present in the malodor counteracting composition in an amount from 30 to 50 wt %, relative to the malodor counteracting composition, and wherein the malodor neutralizing composition is present in the malodor counteracting composition in an amount from 5 to 20 wt %, relative to the malodor counteracting composition.
