Detergent compositions with oleoyl sarcosinate and polymeric dispersing agent

Abstract

The present invention provides a deterent composition comprising: (a) at least 0.1% of an oleoyl sarconsinate of the formula: <IMAGE> wherein M is hydrogen or a cationic moiety; and (b) from about 0.05% to about 15% of a polymeric dispersing agent selected from the group selected from the group consisting of polycarboxylates, polyethylene glycol polymers, polyaspartates and mixtures thereof.

What is claimed is: 
     
       1. A detergent composition comprising (a) at least 0.1% of oleoyl sarconsinate of the formula: ##STR9## wherein M is hydrogen or a cationic moiety; and (b) from about 0.05% to about 15% of a polymeric dispersing agent selected from the group consisting of polycarboxylates, polyethylene glycol polymers, polyaspartates and mixtures thereof.   
     
     
       2. A detergent composition according to claim 1 wherein said polymeric dispersing agent selected from the group consisting of polymeric polycarboxylates derived from acrylic acid, acrylic/maleic acid and mixtures thereof. 
     
     
       3. A detergent composition according to claim 2 comprising from about 1% to about 7% of said dispersing agent and wherein said dispersing agent comprises polymerized acrlyic acid or a soluble salt thereof and has an average molecular weight of from about 2,000 to about 10,000. 
     
     
       4. A detergent composition according to claim 1 wherein M is selected from hydrogen or alkali metal salts. 
     
     
       5. A detergent composition according to claim 4 wherein said alkali metal salts is selected from sodium or potassium. 
     
     
       6. A detergent composition according to claim 1 further comprising at least 0.5% of a detersive surfactant, other than said oleoyl sarcosinate surfactant, selected from anionic and nonionic detersive surfactants. 
     
     
       7. A detergent composition according to claim 6 wherein said detersive surfactant comprises alkyl sulfate, alkyl ethoxylated sulfates, alkyl ester sulfonate, alkyl benzene sulfonates, alkyl ethoxylates, alkyl polyglycosides, alkyl phenol ethoxylates, paraffin sulfaontes, polyhydroxy fatty acid amides, and mixtures thereof. 
     
     
       8. A detergent composition according to claim 7 comprising from about 1% to about 55% by weight of the composition of said detergent surfactant. 
     
     
       9. A detergent composition according to claim 1 further comprising at least about 1% detergent builder. 
     
     
       10. A detergent composition according to claim 9 wherein said builder is selected from the group consisting of zeolite, silicate, carbonate, citrate and mixtures thereof. 
     
     
       11. A method for cleaning substrates in aqueous solution with a detergent composition comprising detersive surfactant and a polymeric dispersing agent, wherein the improvement comprises including in said detergent composition at least about 0.1% by weight of the composition of a oleoyl sarcosinate surfactant of the formula ##STR10## wherein M is a hydrogen or cationic moiety and wherein said dispersing agent is selected from the group consisting of polycarboxylates, polyethylene glycol polymers, polyaspartates and mixtures thereof.
