Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
49 words
A lip-film composition comprising: (a) water; (b) an alkali-dispersible, water-insoluble thermoplastic film-forming resin; (c) a volatile base in sufficient quantity to solubilize the film-forming resin; and (d) a water insoluble plasticizer, said lip-film composition forming a flexible, long-wearing, water-resistant film when applied to the lips and allowed to dry.
Claim 2
Dependent Claim
49 words
A lip-film composition comprising: (a) water; (b) an alkali-dispersible, water-insoluble thermoplastic film-forming resin; (c) a volatile base in sufficient quantity to solubilize the film-forming resin; and (d) a water insoluble plasticizer, said lip-film composition forming a flexible, long-wearing, water-resistant film when applied to the lips and allowed to dry.
Claim 3
Dependent Claim
15 words
A lip-film composition according to claim 1, additionally comprising one or more cosmetically acceptable colorants.
Claim 4
Dependent Claim
