Abstract
The present invention relates to novel, quick drying nail enamel compositions which dry in a period of time no greater than about three minutes. The compositions of the present invention preferably dry in a period no greater than about two minutes and most preferably dry in a period no greater than about 90 seconds. Compositions drying in a period less than 60 seconds are especially preferred and are also described. The compositions of the present invention which contain sufficient quantities of organoclay thixotropic agents have acceptable static viscosities ranging from about 400 to about 1200 centipoises and may accommodate numerous pigments to produce nail enamel compositions exhibiting favorable characteristics, including acceptable durability and gloss.
Claims46
A quick-dry composition for coating natural and synthetic nails of animals and humans comprising:
- a) about 7% to about 25% by weight of a primary film-forming polymer;
- b) about 3% to about 13% by weight of a secondary film-forming polymer;
- c) an amount of at least one plasticizer effective to provide said composition with acceptable flexibility on said nail;
- d) an amount of at least one organoclay thixotropic agent effective to produce gelling of said composition;
- e) about 0.025% to about 4.0% by weight of at least one pigment;
- and
- f) an amount of acetone ranging from about 4.5% to about 35% by weight of said composition in combination with a wetting agent and a diluent solvent said solvent combination dissolving said primary and secondary film-forming polymers and said plasticizer and producing a composition having a static viscosity ranging from about 400 to about 1200 centipoises, said composition drying within about three minutes or less to a coating exhibiting a substantial absence of tack.
The composition according to clam 1 wherein said organoclay thixotropic agent is stearalkonium hectorite.
A quick-dry composition for coating natural and synthetic nails of animals and humans comprising:
- a) an amount of a primary film-forming polymer ranging from about 5% to about 25% by weight;
- b) an amount of a secondary film-forming polymer ranging from about 3.0% to about 13% by weight;
- c) an amount of at least one plasticizer effective to provide said composition with acceptable flexibility on said nail;
- d) about 0.5% to about 2.0% by weight of at least one organoclay thixotropic agent;
- e) at least one pigment;
- and
- f) an amount of acetone ranging from about 15% to about 35% by weight of said composition in combination with a wetting agent and a diluent solvent said solvent combination dissolving said primary and secondary film-forming polymers and said plasticizer and producing a composition having a static viscosity ranging from about 400 to about 1200 centipoises, said composition drying on a natural or synthetic nail within about two minutes or less to a coating exhibiting a substantial absence of tack.
A quick-dry composition for coating natural and synthetic nails of animals and humans comprising:
- a) an amount of nitrocellulose as a primary film-forming polymer ranging from about 5% to about 25% by weight of said composition;
- b) an amount of toluene-sulfonamide formaldehyde resin as a secondary film-forming polymer ranging from about 3% to about 13% by weight of said composition;
- c) an amount of at least one plasticizer in an amount ranging from about 2.0% to about 10% by weight of said composition;
- d) an amount of an organoclay thixotropic agent effective to produce gelling of said composition;
- e) at least one pigment in an amount ranging from about 0.025 to about 4% by weight of said composition;
- and
- f) a solvent combination comprising an amount of acetone ranging from about 13% to about 35% by weight of said composition in combination with at least one wetting agent selected from the group consisting of ethanol, isopropanol and n-butanol in an amount less than about 20% by weight of said composition and at least one ester selected from the group consisting of methyl acetate, ethyl acetate, propyl acetate, n-butyl acetate and amyl acetate, said solvent combination dissolving said primary film-forming polymer and said secondary film-forming polymer and producing a gelled composition in combination with said organoclay thixotropic agent having a static viscosity ranging from about 400 to about 1200 centipoises, said composition drying within a period of about three minutes or less to a coating exhibiting a substantial absence of tack.
The composition according to clam 8 further including methylethylketone as a solvent.
