Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
98 words
A method of conditioning hair to provide combing, detangling, static fly-away, softness, luster, and manageability benefits comprising rubbing the hair with an article comprised of a flexible substrate having reasonably associated therewith from 0.2 gram to 15 grams per square meter of substrate of a normally solid substantially water-insoluble hair conditioning agent, said agent selected from the group consisting of a quaternary ammonium salt, quaternary imidazolinium salt, fatty alcohol, sorbitan ester, polyhydric alcohol ester, fatty acid salt, aliphatic ether, and mixtures thereof, said rubbing causing the transfer of an effective amount of hair conditioning agent to the hair.
Claim 2
Independent Claim
98 words
A method of conditioning hair to provide combing, detangling, static fly-away, softness, luster, and manageability benefits comprising rubbing the hair with an article comprised of a flexible substrate having reasonably associated therewith from 0.2 gram to 15 grams per square meter of substrate of a normally solid substantially water-insoluble hair conditioning agent, said agent selected from the group consisting of a quaternary ammonium salt, quaternary imidazolinium salt, fatty alcohol, sorbitan ester, polyhydric alcohol ester, fatty acid salt, aliphatic ether, and mixtures thereof, said rubbing causing the transfer of an effective amount of hair conditioning agent to the hair.
