Functional additives for cleansing compositions
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.
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.
