Abstract
Abstract Detergent bar binder comprising (a) fatty acid or alcohol component having an iodine number less than about 20 and a melting point of at least about 50° C. and being selected from the group consisting of fatty acids or alcohols having from 12 to 22 carbon atoms, mono-, di- or triglycerides of such fatty acids, fatty acid esters of such fatty alcohols and mixtures thereof and (b) alkyl amide represented by the formula: ##STR1## where R 1 represents a straight chain alkyl radical containing from 10 to 22 carbon atoms and R 2 represents hydrogen or an alkyl radical containing from 1 to 3 carbon atoms. The binder is used in a non-soap detergent bar containing anionic foaming and foam boosting detergents.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
A detergent bar binder composition comprising the following combination of ingredients: (a) fatty acid or alcohol component having an iodine number less than about 20 and a melting point of at least about 50° C. and being selected from the group consisting of fatty acids or alcohols having from 12 to 22 carbon atoms, mono-, di- or tri-glycerides of such fatty acids, fatty acid esters of such fatty alcohols and mixtures thereof and; (b) alkyl amide represented by the formula: ##STR3## where R 1 represents a straight chain alkyl radial containing from 10 to 22 carbon atoms and R 2 represents hydrogen or an alkyl radical containing from 1 to 3 carbon atoms, said alkyl amide being present in an amount between about 2 and about 30 wt% of said binder composition and said fatty acid or alcohol component being present in an amount between about 70 and about 90 wt% of said binder composition.
Claim 2
Dependent Claim
155 words
A detergent bar binder composition comprising the following combination of ingredients: (a) fatty acid or alcohol component having an iodine number less than about 20 and a melting point of at least about 50° C. and being selected from the group consisting of fatty acids or alcohols having from 12 to 22 carbon atoms, mono-, di- or tri-glycerides of such fatty acids, fatty acid esters of such fatty alcohols and mixtures thereof and; (b) alkyl amide represented by the formula: ##STR3## where R 1 represents a straight chain alkyl radial containing from 10 to 22 carbon atoms and R 2 represents hydrogen or an alkyl radical containing from 1 to 3 carbon atoms, said alkyl amide being present in an amount between about 2 and about 30 wt% of said binder composition and said fatty acid or alcohol component being present in an amount between about 70 and about 90 wt% of said binder composition.
