Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 54 words
A lipstick formulation which is soft but has a good structure, is creamy, shiny and has excellent laydown properties comprising an anhydrous base intermediate comprising one or more waxes and one or more oils, a color intermediate, and at least one acrylates copolymer which imparts creaminess, shininess and superior laydown properties to the formulation.
Claim 2
Dependent Claim 54 words
A lipstick formulation which is soft but has a good structure, is creamy, shiny and has excellent laydown properties comprising an anhydrous base intermediate comprising one or more waxes and one or more oils, a color intermediate, and at least one acrylates copolymer which imparts creaminess, shininess and superior laydown properties to the formulation.
