Abstract
Personal care products for maintaining fingernail and toenail appearance. In particular, nail polish compositions that have a formulation that is both safer and more environmentally-friendly to use. The present nail polish compositions comprise anionic polyester resins such as sodio-sulfonated polyesters and sodio-sulfonated co-polyester-co-polysiloxane copolymers as base resin vehicles.
Claims11
An aqueous-based nail polish composition, comprising:
- an emulsion of a sulfonated polyester resin in water, wherein the sulfonated polyester resin is present in the composition in an amount of from about 1 to about 15 percent by weight of the total weight of the composition;
- an optional pigment;
- and
- a thickening agent in the amount of from 0.01% to 5% by weight of the total weight of the nail polish composition;
- wherein the sulfonated polyester resin comprises a sulfonated co-polyesters-copolysiloxane having the following formula:
- wherein M is a hydrogen or an alkali metal;
- R1 and R3 is independently selected from the group consisting of aryl and alkyl;
- R2 is independently selected from the group consisting of alkyl and oxyalkylene;
- and a, b, c, n and p are each independently about 10 to about 100,000;
- wherein the aqueous-based nail polish composition having a viscosity at 25° C. of from about 5 to about 5,000 cps, the aqueous-based nail polish composition having a drying time of less than 80 seconds, and a glossiness of from about 60 to about 100 gloss units, wherein the glossiness is measured using a Gardner Gloss Metering Unit.

An aqueous-based nail polish composition, comprising:
- an emulsion of a branched sulfonated polyester resin in water, wherein the sulfonated polyester resin is present in the composition in an amount of from about 1 to about 15 percent by weight of the total weight of the composition;
- an optional pigment;
- and
- a thickening agent in the amount of from 0.01% to 5% by weight of the total weight of the nail polish composition;
- wherein the sulfonated polyester resin comprises a sulfonated co-polyesters-copolysiloxane having the following formula:
- wherein M is a hydrogen or an alkali metal;
- R1 and R3 is independently selected from the group consisting of aryl and alkyl;
- R2 is independently selected from the group consisting of alkyl and oxyalkylene;
- and a, b, c, n and p are each independently about 10 to about 100,000;
- further wherein the aqueous-based nail polish composition is odorless and has a viscosity at 25° C. of from about 5 to about 5,000 cps, and a glossiness of from about 60 to about 100 gloss units, wherein the glossiness is measured using a Gardner Gloss Metering Unit.
