Abstract

A malodor counteractant composition comprising beads of a water absorbent polymer and an aromachemical comprising at least two aldehydes. Optional ingredients include a solvent for the aromachemical and one or more surfactants.

Claims (17)

1. An aqueous composition comprising:

(1) a water absorbent co-polymer in the form of beads and comprising units of sodium acrylate,

(2) an aromachemical comprising

(a) one or more compounds selected from the group consisting of: decanal; undecanal; dodecanal; undecene-10-al; 2-methyl-undecanal; 2,3,5,5-tetramethylhexanal; 1-formyl-2,4-dimethyl-2-cyclohexene; 1-formyl-3,5-dimethyl-4-cyclohexene; 1-formyl-2,3,5-trimethyl-4-cyclohexene; 1-formyl-2,4,6-trimethyl-3-cyclohexene; ([5.2.1.0]-tricyclo-8-decylidene)-4-butanal; 2,6,10-trimethyl-9-undecenal; (4-methyl-3-pentenyl)-4-cyclohexene-3-yl carboxaldehyde; 7-formyl-5-isopropyl-2-methyl-[2.2.2]-bicyclo-2-octene; and 2-formyl-8-dimethyl-1,2,3,4,5,6,7,8-octahydronaphthalene; citronellal; campholenic aldehyde; α-methyl-3,4-methylenedioxyhydrocinnamic aldehyde; cyclamen aldehyde; lilial; canthoxal; phenylacetic aldehyde; 3-phenylpropionic aldehyde; hydratropic aldehyde; α-methyl-3,4-methylenedioxyhydrocinnamic aldehyde; cyclamen aldehyde; lilial; canthoxal; phenylacetic aldehyde; 3-phenylpropionic aldehyde; hydratropic aldehyde; alkoxyacetaldehydes; ω-hydroxyaldehydes; and ω-alkoxyaldehydes, and

(b) one or more compounds selected from the group consisting of: myrtenal; perilla aldehyde; variously substituted 2-furyl carboxaldehydes; cinnamic aldehyde; amylcinnamic aldehyde; hexylcinnamic aldehyde; benzaldehyde; anisic aldehyde; heliotropine; veratric aldehyde; vanillin; isovanillin; and ethylvanillin,

(3) optionally, an organic solvent or solubilizing agent,

(4) optionally, a surfactant, and

(5) a major proportion of water.

2. A composition according to claim 1 in which the co-polymer comprises acrylamide.

3. A composition according to claim 1 in which the co-polymer beads are present in an amount ranging from about 0.15% to about 5.0% by weight and the fragrance is present in an amount ranging from about 0.5% to about 10% by weight.

4. A composition according to claim 3 which comprises a solvent present in an amount of from about 0.5% to about 10.0% by weight.

5. A composition according to claim 4 in which the solvent is present in an amount of from 1.5% to 5.0% by weight.

6. A composition according to claim 5 in which the solvent is selected from the group consisting of ethanol, ethyl phthalate, diethyl phthalate, benzyl benzoate and ethyl citrate.

7. A composition according to claim 6 in which the solvent is ethanol.

8. A composition according to claim 3 which comprises one or more surfactants in a total amount of from about 1.0% by weight to about 30% by weight.

9. A composition according to claim 8 in which the surfactants are present in an amount ranging from 10% to 17%.

10. A composition according to claim 1 in which the fragrance comprises α-methyl-3,4-methylene-dioxyhydrocinnamic aldehyde and amylcinnamic aldehyde.
