Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A composition for the conditioning of hair which has been previously treated with an agent having an alkaline pH consisting essentially of based on the total weight of the composition: (a) from about 0.4% to about 10% of at least one cationic polymer product; (b) from about 0.2% to about 20% of an amphoteric surfactant product; and (c) sufficent acid to give the composition a pH in the range of from about 1 to about 6; the ratio α=[polymer (mer)]/[detergent (mol)] being from about 0.2 to about 5; in (d) an aqueous carrier.
Claim 2
Dependent Claim
93 words
