Abstract

Functional additives for cleansing compositions exhibiting enhanced anti soil-re-deposition and/or dye transfer inhibitory properties comprising polymers in the form of homopolymers, copolymers or terpolymers synthesized from at least one hydrophobic monomer. Examples of hydrophobic monomers include N-vinyl caprolactam, vinyl acetate, vinyl esters, acrylated glycols, methacrylamide, C1 to C12 alkyl- and C1 to C12 dialkylacrylamide, C1 to C12 alkyl- and C1 to C12 dialkylmethacrylamide, C1 to C12 alkyl aery late, C1 to C12 alkyl methacrylate, 4-butyl phenyl maleimide, octyl acrylamide.

Claims

1. A cleaning composition comprising as an integral part of said composition functional additive having enhanced anti soil-redeposition and/or dye transfer inhibitory activities comprising an uncross-linked polymer selected from the group consisting of

2. The cleansing composition according to claim 1 wherein said cleansing composition is in the form of a liquid, solid, semisolid, emulsion, dispersion or gel.

3. The cleansing composition according to claim 1 wherein said functional additive is present in an amount of from 0.001 to 50 weight percent, based on the total weight of the cleansing composition.

4. A cleansing composition according to claim 3, wherein the functional additive is present in an amount of from 0.01 to 25 weight percent.

5. A cleansing composition according to claim 4, wherein the functional additive is present in an amount of from 0.1 to 5 weight percent.

6. The cleansing composition according to claim 1 further comprising at least one of a surfactant, builder, chelant, bleaching agent, oxidizing agent, supplementary soil-suspending agent, foam suppressor, additional soil release agent, optical brightener, abrasive, bactericide, tarnish inhibitor, coloring agent, and perfume.

7. A method of cleaning fabric with enhanced anti soil-redeposition and/or minimizing dye transfer during the wash cycle of a laundering process comprising the following steps:

(a) washing a load of fabrics in a wash solution containing a cleansing composition according to claim 1;

(b) rinsing said load of fabrics;

(c) drying said load of fabrics; and

(d) washing all or part of said load of fabrics,

said load releasing an effective amount of anti soil-redeposition effect and/or dye transfer inhibitor into a wash solution containing a cleansing composition.

8. The method according to claim 7, wherein said wash solution contains at least some colored fabrics which release dyes and contains fabrics which will be discolored by the released dyes.

9. The method according to claim 8, wherein said fabric is selected from the group consisting of cotton, denim, polyacrylics, polyamides, polyesters, polyolefins, rayons, wool, linen, jute, ramie, hemp, sisal, regenerated cellulosic fibers leather, and combinations thereof.
