Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
93 words
A leave-on facial emulsion composition, substantially free from fats and oils and anionic surfactants, comprising: (a) from about 0.01% to about 5% of a cationic surfactant; (b) from about 0.01% to about 5% of one or more of a carboxylic acid copolymer; (c) from about 1% to about 10% of a humectant; and (d) a cosmetically acceptable carrier; wherein said composition provides a contact angle between sebum and skin from 0° to about 10°, and a spreading index for sebum migration greater than about 8300 pixels over the time period from 0-5 minutes.
Claim 2
Dependent Claim
93 words
A leave-on facial emulsion composition, substantially free from fats and oils and anionic surfactants, comprising: (a) from about 0.01% to about 5% of a cationic surfactant; (b) from about 0.01% to about 5% of one or more of a carboxylic acid copolymer; (c) from about 1% to about 10% of a humectant; and (d) a cosmetically acceptable carrier; wherein said composition provides a contact angle between sebum and skin from 0° to about 10°, and a spreading index for sebum migration greater than about 8300 pixels over the time period from 0-5 minutes.
