Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
106 words
A process for preparing high quality nail polish compositions comprising: grinding a pigment material in an essentially non-flammable, non-explosive mill base grinding medium comprising a water insoluble protective colloid and a low volatizing plasticizer in amounts sufficient to form a pigment dispersion paste; combining said pigment paste with a lacquer formulation containing sufficient amounts of a primary film forming material and modifying resins therefor; and mixing said pigment paste and lacquer formulation to provide a final, dermatologically acceptable nail polish composition having a pigment concentration of at least from to 2.0% to 7 by weight and a Newtonian viscosity of not greater than about 600 cps.
Claim 2
Dependent Claim
106 words
A process for preparing high quality nail polish compositions comprising: grinding a pigment material in an essentially non-flammable, non-explosive mill base grinding medium comprising a water insoluble protective colloid and a low volatizing plasticizer in amounts sufficient to form a pigment dispersion paste; combining said pigment paste with a lacquer formulation containing sufficient amounts of a primary film forming material and modifying resins therefor; and mixing said pigment paste and lacquer formulation to provide a final, dermatologically acceptable nail polish composition having a pigment concentration of at least from to 2.0% to 7 by weight and a Newtonian viscosity of not greater than about 600 cps.
Claim 3
Dependent Claim
52 words
A process according to claim 1 wherein the pigment material is selected from the group consisting of a conventional single pigment; a single pearlescent; a mixture of a conventional single pigment and a single pearlescent; a mixture of conventional pigments; a mixture of pearlescents; and a mixture of conventional pigments and pearlescents.
Claim 4
Dependent Claim
23 words
A process according to claim 1 wherein the pigment dispersion paste is comprised of at least 20.0% by weight of the pigment material.
Claim 5
Dependent Claim
52 words
A process according to claim 1 wherein the protective colloid is compatible with the film forming material in the lacquer formulation and wherein the amount of said protective colloid is sufficient to coat the dispersed pigment particles with at least a monomolecular layer of said colloid to prevent said particles from agglomerating.
Claim 6
Dependent Claim
41 words
The process according to claim 4 wherein the protective colloid is selected from the group consisting of saccharide based polymers; acrylic polymers; polyesters; alkyd resins; polyamides; cellulosic polymers; sulfonated napthalenes; vinyl polymers; formaldehyde condensates; polyurethanes; substituted pyrrolidone polymers; and polypropylene oxides.
Claim 7
Dependent Claim
37 words
The process according to claim 5 wherein the protective colloid is selected from the group consisting of toluene sulfonamideformaldehyde condensate; methyl-butyl methacrylate copolymer; sucrose benzoate; ethyl cellulose; polymeric esterified pentaerythritol; and a dimer acid based polyamide resin.
Claim 8
Dependent Claim
32 words
The process according to claim 1 wherein the amount of the protective colloid present in the mill base ranges from about 2.0% to about 25.0% by weight of the mill base ingredients.
Claim 9
Dependent Claim
35 words
The process according to claim 1 wherein the plasticizer is essentially non-flammable, sufficiently solubilizes the protective colloid present in the mill base and is compatible with the film forming material present in the lacquer formulation.
Claim 10
Dependent Claim
25 words
The process according to claim 8 wherein the plasticizer is selected from the group consisting of N-ethyl toluene sulfonamide; butyl benzyl phthalate; and tricresyl phosphate.
Claim 11
Dependent Claim
31 words
The process according to claim 8 wherein the plasticizer is present in the mill base in amounts ranging from about 75.0% to about 98.0% by weight of the mill base ingredients.
Claim 12
Dependent Claim
39 words
The process according to claim 1 wherein the pigment material and mill base are milled under high energy shearing forces to provide a pigment dispersion paste having an average pigment particle size between about 0.1 to about 2.0 microns.
Claim 13
Dependent Claim
28 words
A process according to claim 1 wherein the film forming material present in the lacquer formulation is selected from the group consisting of cellulose resins and acrylic resins.
Claim 14
Dependent Claim
14 words
The process according to claim 12 wherein the film forming material is cellulose nitrate.
Claim 15
Dependent Claim
28 words
The process according to claim 12 wherein the film forming material is present in amounts ranging from about 10.0% to about 20.0% by weight of the lacquer formulation.
Claim 16
Dependent Claim
18 words
A process according to claim 1 wherein at least two modifying resins are present in the lacquer formulation.
Claim 17
Dependent Claim
31 words
A process according to claim 15 wherein the amount of modifying resins present in the lacquer formulation ranges from about 7.5% to about 18.0% by weight of the total lacquer ingredients.
Claim 18
Dependent Claim
19 words
A process according to claim 15 wherein the modifying resins are toluene sulfonamide-formaldehyde condensate and sucrose benzoate/sucrose acetate-isobutyrate copolymer.
