Abstract

Compositions comprising hydrophobically modified malodor control polymers and methods thereof are provided. In some embodiments, the composition comprises a malodor control polymer, a malodor counteractant comprising a perfume, an aqueous carrier, and a ph of about 6 to about 8. Such compositions may be used to reduce or neutralize malodors on surfaces or in the air.

First claim

What is claimed is:

1. A composition for reducing malodor comprising:
(a) about 0.01% to about 0.8%, by weight of said composition, of a water soluble malodor control polymer having 1% water solubility and having the structure (I):
P(R) x   (I)

 wherein:
P is a 95% hydrolyzed PVam;
x is degree of substitution of the amine sites on the polymer and is less than 100%; and
R is a C2 to C6 alkyl or alkenyl;

(b) a malodor counteractant comprising a perfume material, said perfume material comprises at least one aliphatic aldehyde present in the amount of about 0.001% to about 5%, by weight of said composition;
(c) an aqueous carrier; and

wherein said composition comprises a pH of about 6 to about 8.

2. The composition of claim 1 wherein R is a C4-C6 alkyl or alkenyl.

3. The composition of claim 1 wherein R is a C6 alkyl or alkenyl.

4. The composition of claim 1 wherein said at least one aliphatic aldehyde is present in the amount of about 0.001% to about 1% by total weight of said composition.

5. The composition of claim 1 wherein said at least one aliphatic aldehyde is selected from the group consisting of bourgeonal, citral, citronellyl oxyacetaldehyde, cymal, decyl aldehyde, helional, hexyl cinnamic aldehyde, lauric aldehyde, ligustral, lyral, melonal, methyl dihydro jasmonate, methyl nonyl acetaldehyde, methyl phenyl carbinyl acetate, nonyl aldehyde, 2′ 6-nonadien-1-al, octyl aldehyde, oxane, P.T. bucinal, polysantol, rhubafuran, tripal, and mixtures thereof.

6. The composition of claim 1 wherein said composition further comprises a buffering agent selected from the group consisting of carboxylic acid, dicarboxylic acid, N-(2-Acetamido)-2-aminoethanesulfonic acid, and mixtures thereof.

7. The composition of claim 1 wherein said composition comprises a pH of about 7.

8. The composition of claim 1 wherein said composition is free of anionic surfactants.

9. The composition of claim 1 wherein said composition is free of an ingredient that soils or stains a fabric surface.

10. The composition of claim 1 wherein said composition further comprises no more than 3% surfactant by weight of said composition.

11. The composition of claim 1 wherein said composition further comprises no more than 1% surfactant by weight of said composition.

12. The composition of claim 1 wherein said aqueous carrier is present in an amount of 50% to about 99.5%.

13. A method of reducing malodor comprising the steps of:
a. providing the composition of claim 1 ;
b. dispersing an effective amount of said composition on an inanimate surface or in the air.
