Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
63 words
A method of imparting lubricity to a substrate comprising skin, hair or mucous membranes including contacting the substrate with a composition including a sufficient amount of a salt of ##STR5## wherein x has a value such that the molecular weight of the anionic portion of the polymer is from about 1,000,000 to about 5,000,000 to achieve a lubricated feel upon the contacted substrate.
Claim 2
Independent Claim
63 words
A method of imparting lubricity to a substrate comprising skin, hair or mucous membranes including contacting the substrate with a composition including a sufficient amount of a salt of ##STR5## wherein x has a value such that the molecular weight of the anionic portion of the polymer is from about 1,000,000 to about 5,000,000 to achieve a lubricated feel upon the contacted substrate.
