Abstract

The present invention relates to a stable, aqueous odor-absorbing and wrinkle controlling composition, preferably for use on inanimate surfaces, especially fabrics. The composition comprises from about 0.1% to about 20%, by weight of the composition, of solubilized, water-soluble, uncomplexed cyclodextrin and an effective amount of at least one ingredient to improve the performance of the composition selected from the group consisting of: (1) cyclodextrin compatible surfactant; (2) cyclodextrin compatible antimicrobial active; and (3) mixtures thereof. The composition also comprises a wrinkle control agent which is fabric lubricant, shape retention polymer, hydrophilic plasticizer, lithium salt, or mixtures thereof. Hydrophilic perfume improves acceptance. Optionally, the composition can contain low molecular weight polyols; metallic salts to help control odor; a humectant, etc. The composition is essentially free of any material that would soil or stain fabric. The composition is preferably applied as small particle size droplets, especially from spray containers. The cyclodextrin/surfactant combination, either alone, or in combination with the other ingredients, provides improved antimicrobial activity.

Dependent claims

A stable, aqueous odor-absorbing composition comprising:

(A) an effective amount to absorb malodors of solubilized, uncomplexed cyclodextrin;
(B) an effective amount to lower the surface tension of the composition, of cyclodextrin compatible surfactant;
(C) an effective amount, to kill, or reduce the growth of microorganisms on a treated surface, of cyclodextrin compatible and water soluble antimicrobial active;
(D) optionally, an effective amount to improve the odor of the composition of hydrophilic perfume containing at least about 50% by weight of the perfume of ingredients having a ClogP of less than about 3.5 and, optionally, a minor amount of perfume ingredients selected from the group consisting of ambrox, bacdanol, benzyl salicylate, butyl anthranilate, cetalox, damascenone, alpha-damascone, gamma-dodecalactone, ebanol, herbavert, cis-3-hexenyl salicylate, alpha-ionone, beta-ionone, alpha-isomethylionone, lilial, methyl nonyl ketone, gamma-undecalactone, undecylenic aldehyde, and mixtures thereof;
(E) optionally, from about 0.01% to about 3% by weight of the composition of low molecular weight polyol;
(F) optionally, from about 0.001% to about 0.3% by weight of the composition of aminocarboxylate chelator;
(G) optionally, an effective amount of metallic salt for improved odor benefit;
(H) optionally, an effective amount of enzyme for improved odor control benefit;
(I) optionally, an effective amount to prevent spoilage of the composition of solubilized, water-soluble, antimicrobial preservative;
(J) an effective amount to remove or noticeably reduce the appearance of wrinkles on fabric of cyclodextrin compatible fabric wrinkle control agent;
and
(K) aqueous carrier;
wherein the combination of (B) and (C) provides improved antimicrobial activity.
