Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A composition, for conditioning the hair or skin, consisting essentially of (a) between about 1.5 and 15 weight percent of an N-alkylcarobxylate-N-fatty alkyl-quaternary amine or -ammonium compound of the formula ##STR5## wherein: R 1 is fatty alkyl; x is from 1 to about 3; y is from 1 to about 6; R 2 , R 3 , R 4 and R 5 are hydrogen, alkyl or hydroxyalkyl; R 4 , R 5 , R 6 and R 7 may also form a nitrogen-containing ring together with the carbon and nitrogen atoms to which they are attached; and Z represents an amido radical group or a carbon-carbon single bond; and (b) between about 0.5 and 5 weight percent of a superfatting material; together with (c) acid sufficient to provide a pH between about 2.2 and about 3.2 in said composition.
