Oleoyl sarcosinate with polyhydroxy fatty acid amides in cleaning products

Abstract

Detergent compositions comprise oleoyl sarcosinate and polyhydroxy fatty acid amide surfactants which, together, provide compositions with improved cleaning performance and good solubility. Thus, oleoyl sarcosinate is combined with C10-C18 N-methyl glucamide and builders, enzymes and other detersive ingredients to provide a laundry detergent. Use of this mixture of surfactants in dishwashing detergents is also described.

What is claimed is: 
     
       1. A cleaning composition comprising: (a) at least about 0.5%, by weight, of oleoyl sarcosinate; and   (b) at least about 1%, by weight, of a polyhydroxy fatty acid amide surfactant.   
     
     
       2. A composition according to claim 1, wherein the polyhydroxy fatty acid amide is a member selected from the group consisting of the C 10-18  fatty acid amides of N-methyl glucamine, the C 10  -C 18  fatty acid amides of N-(3-methoxypropyl) glucamine, and mixtures thereof. 
     
     
       3. A composition according to claim 1 which comprises at least about 3%, by weight, of a mixture of said surfactants (a) and (b). 
     
     
       4. A composition according to claim 3 which comprises from about 3% to about 55%, by weight, of a mixture of surfactants (a) and (b), at a weight ratio of (a):(b) in the range from about 1:10 to about 10:1. 
     
     
       5. A composition according to claim 4 wherein the (a):(b) ratio is from about 1:1 to about 3:1. 
     
     
       6. A detergent composition according to claim 1 which additionally comprises a detergency builder. 
     
     
       7. A detergent composition according to claim 1 which additionally comprises enzymes. 
     
     
       8. A detergent composition according to claim 1 which additionally comprises a soil release agent. 
     
     
       9. A composition according to claim 1 which additionally comprises a dye transfer inhibitor. 
     
     
       10. A composition according to claim 1 which additionally comprises bleach. 
     
     
       11. A composition according to claim 1 which additionally comprises a non-oleoyl sarcosinate, non-polyhydroxy fatty acid amide detersive surfactant. 
     
     
       12. A composition according to claim 1 which additionally comprises a dispersing agent. 
     
     
       13. A composition according to claim 1 which additionally comprises a suds suppressor. 
     
     
       14. A composition according to claim 1 which additionally comprises a mixture of builder, bleach and enzyme. 
     
     
       15. A method for cleaning surfaces, comprising contacting said surfaces with an aqueous medium which contains at least about 50 ppm of a composition according to claim 1.
