Claims15
A cosmetic film, comprising butylphthalimide isopropylphthalimide;
- one or more primary film forming polymers, a suspending agent, and one or more secondary film forming resins.
A colored nail enamel, consisting essentially of butylphthalimide isopropylphthalimide in a concentration of about 1 to 10 percent by weight;
- ethyl acetate in a concentration of about 37 to 39 percent by weight;
- butyl acetate in a concentration of about 19 to 26 percent by weight;
- nitrocellulose in a concentration of about 11 to 14 percent by weight;
- isopropyl alcohol in a concentration of about 5 to 6 percent by weight;
- optionally, polyester resin in a concentration of about 12 percent by weight;
- optionally, tosylamide/epoxy resin in a concentration of about 8 to 10 percent by weight;
- stearalkonium hectorite as a suspension agent in a concentration of about 0.5 to 2 percent by weight;
- optionally, acrylic copolymer in a concentration of about 1.5 percent by weight;
- and coloring agents in a concentration effective to produce color.
A colored nail enamel, comprising:
- ethyl acetate;
- butyl acetate;
- nitrocellulose;
- isopropyl alcohol;
- tosylamide/epoxy resin;
- butylphthalimide isopropylphthalimide in a concentration of about 1 to about 10 percent by weight;
- one or more suspending agents, and coloring agents.
A method for making a cosmetic film and that has a hardness, adhesion, flexibility, gloss and long shelf life that prevent cracking for at least about 7 days after application to a nail, comprising:
- providing one or more primary film forming polymers;
- providing one or more secondary film forming resins;
- providing butylphthalimide isopropylphthalimide;
- providing one or more suspending agents;
- and blending the primary film forming polymer, secondary film forming resin and butylphthalimide isopropylphthalimide in a weight percent concentration of about 1 to 10 weight percent to make a cosmetic film having a hardness, adhesion, flexibility, gloss and long shelf life.
A colored nail enamel, comprising:
- An acetate;
- Nitrocellulose;
- butylphthalimide isopropylphthalimide;
- tosylamide/epoxy resin;
- stearalkonium hectorite;
- and
- coloring agents.
