1. A malodor neutralizing composition, comprising: (1) a cyclohexanone substituted with C1-C5 branched or unbranched alkyl or an unsaturated alicyclic ketone of the formula wherein the ring contains 1 double bond at position 1, position 2 (endocyclic) or position 2 (exocyclic) or contains 2 conjugat
1. A malodor neutralizing composition, comprising: (1) a cyclohexanone substituted with C1-C5 branched or unbranched alkyl or an unsaturated alicyclic ketone of the formula wherein the ring contains 1 double bond at position 1, position 2 (endocyclic) or position 2 (exocyclic) or contains 2 conjugated double bonds at positions 1 and 3,R1 is a branched or unbranched C3-C5 alkyl containing a carbonyl or a branched or unbranched C3-C5 alkenyl containing a carbonyl, andR2 is hydrogen or methyl; and(2) citric acid or undecylenic acid; wherein the composition is free of a nitrile and the amount of ingredient (2) is 10-50% by weight of the total amount of ingredients (1) and (2). 2. The composition of claim 1, wherein ingredient (1) is an unsaturated alicyclic ketone of structure (I). 3. The composition of claim 2, wherein R1 is alkyl or alkylene having 4 or 5 carbon atoms and the carbonyl group is in the 1′ position or 3′ position relative to the ring. 4. The composition of claim 3, wherein R1 is alkylene having 5 carbon atoms. 5. The composition of claim 2, wherein the unsaturated alicyclic ketone has the structure in which, in R1, the carbonyl group is in the 3′ position relative to the ring. 6. The composition of claim 5, wherein the unsaturated alicyclic ketone is 7. The composition of claim 2, wherein the unsaturated alicyclic ketone has the structure in which, in R1, the carbonyl group is in the 3′ position relative to the ring. 8. The composition of claim 7, wherein the unsaturated alicyclic ketone is 9. The composition of claim 2, wherein the unsaturated alicyclic ketone has the structure in which, in R1, the carbonyl group is in the 1′ position relative to the ring. 10. The composition of claim 9, wherein the unsaturated alicyclic ketone is 11. The composition of claim 2, wherein the unsaturated alicyclic ketone has the structure in which, in R1, the carbonyl group is in the 1′ position relative to the ring. 12. The composition of claim 11, wherein the unsaturated alicyclic ketone is 13. The composition of claim 1, wherein the ingredient (1) is a cyclohexanone substituted with C1-05 branched or unbranched alkyl. 14. The composition of claim 13, wherein the cyclohexanone is 15. The composition of claim 1, wherein ingredient (2) is citric acid. 16. The composition of claim 1, wherein ingredient (2) is undecylenic acid. 17. A product, comprising: the malodor neutralizing composition of claim 1;wherein the product is a perfumed product, a household product, or a personal care product. 18. A method for reducing malodor, comprising: contacting a source of the malodor with an effective amount of the composition of claim 1. 19. A method for reducing malodors emanating from a household or personal care product, comprising: admixing to the product the malodor neutralizing composition of claim 1.
