Abstract
Abstract This invention relates to a detergent composition and a method for substantially eliminating separation of nonionic from a detergent slurry. The composition consists essentially of: (a) about 10%-60% builder; (b) about 2%-25% nonionic surfactant; (c) 0% to about 30% other ingredients; (d) an effective amount to substantially prevent separation of the nonionic from the detergent composition of a surface active iminodipropionate of the general formula: ##STR1## wherein R is an alkyl, hydroxyalkyl or oxyalkyl group containing from about 10 to about 18 carbon atoms and M is an alkali metal cation; and (e) the remainder water.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
An aqueous detergent slurry composition having a solids content of about 55 to about 75% by weight consisting essentially of: (a) about 10%-60% builder; (b) about 2%-25% nonionic surfactant; (c) 0% to about 30% other ingredients; (d) an effective amount to substantially prevent separation of the nonionic from the detergent composition of a surface active iminodipropionate of the general formula: ##STR5## wherein R is an alkyl, hydroxyalkyl or alkoxyalkyl group containing from about 10 to about 18 carbon atoms and M is an alkali metal cation; and (e) the remainder water whereby said nonionic does not undergo substantial separation from said composition.
Claim 2
Dependent Claim
102 words
An aqueous detergent slurry composition having a solids content of about 55 to about 75% by weight consisting essentially of: (a) about 10%-60% builder; (b) about 2%-25% nonionic surfactant; (c) 0% to about 30% other ingredients; (d) an effective amount to substantially prevent separation of the nonionic from the detergent composition of a surface active iminodipropionate of the general formula: ##STR5## wherein R is an alkyl, hydroxyalkyl or alkoxyalkyl group containing from about 10 to about 18 carbon atoms and M is an alkali metal cation; and (e) the remainder water whereby said nonionic does not undergo substantial separation from said composition.
Claim 3
Dependent Claim
