Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
A method of treating body odor which comprises applying to skin a composition comprising 0.01 to 5%, based on total composition weight, of an antimicrobial agent selected from the group consisting of trichlocarban (3, 4, 4'-trichloro carbanilide), triclosan (2, 4, 4'-trichloro-2'-hydroxy diphenyl ether), benzalkonium chloride, zinc phenosulfonate and zinc ricinoleate, 0.01 to 12%, based on total composition weight, of a cationic polymer selected from the group consisting of homopolymers of dimethyldiallyl ammonium chloride having an intrinsic viscosity of 0.1 to 2.5 and copolymers of dimethldiallyl ammonium chloride and acrylamide having an intrinsic viscosity of about 4.0 which contain about 10% to about 75%, by weight, dimethyldiallyl ammonium chloride and about 25% to about 90%, by weight, acrylamide, and the balance water.
Claim 2
Independent Claim
121 words
A method of treating body odor which comprises applying to skin a composition comprising 0.01 to 5%, based on total composition weight, of an antimicrobial agent selected from the group consisting of trichlocarban (3, 4, 4'-trichloro carbanilide), triclosan (2, 4, 4'-trichloro-2'-hydroxy diphenyl ether), benzalkonium chloride, zinc phenosulfonate and zinc ricinoleate, 0.01 to 12%, based on total composition weight, of a cationic polymer selected from the group consisting of homopolymers of dimethyldiallyl ammonium chloride having an intrinsic viscosity of 0.1 to 2.5 and copolymers of dimethldiallyl ammonium chloride and acrylamide having an intrinsic viscosity of about 4.0 which contain about 10% to about 75%, by weight, dimethyldiallyl ammonium chloride and about 25% to about 90%, by weight, acrylamide, and the balance water.
