Abstract

Single phase cosmetic adhesive compositions that are flexible and resistant to water below a selected temperature, 43° C. for example. The adhesive compositions wear well, are smudge and flake resistant, as well as oil resistant, making them very suitable for long wear without adhesive failure. Adhesive compositions according to the invention comprise specific combinations of acrylates/VA copolymer and acrylates copolymer in a cosmetically acceptable base or delivery vehicle. Adhesive compositions according to the invention are hydrophilic and easily removed when scrubbed with water above a certain temperature, but not as easily removed with water below that temperature. The adhesive compositions are easy to manufacture, flexible and comfortable, and suitable for use on skin, lips, hair and nails, particularly to secure strips of false eyelashes and eyebrows, as well as individual lash and brow extensions. Cosmetic adhesives of the present invention may also be used to affix glitter or extensions to skin, hair, lips, or nails, and other cosmetic products to keratinic surfaces.

Claims (19)

1. A single phase, aqueous cosmetic adhesive composition comprising, by total weight of the composition:

20% to 30% of acrylates/VA copolymer;

0.5% to 2.5% of acrylates copolymer;

wherein the ratio of the acrylates/VA copolymer to the acrylates copolymer is in the range of 16:1 to 20:1;

40% to 65% of water;

no more than 0.5% of hydrophobic oils or waxes;

no more than 4% glycol;

no more than 3% of surfactants and emulsifiers;

no more than 0.25% of clay particles or undissolved particulate material; and

no more than 0.5% of polyurethane.

2. The adhesive composition of claim 1 having no hydrophobic oils or waxes.

3. The adhesive composition of claim 1 having no surfactants or emulsifiers.

4. The adhesive composition of claim 1 having no clay particles or undissolved particulate material.

5. The adhesive composition of claim 1 having no polyurethane.

6. The adhesive composition of claim 1 having less than 0.5% glycol.

7. The adhesive composition of claim 1 having no hydrophobic oils or waxes, no surfactants or emulsifiers, no clay particles or undissolved particulate material, and no polyurethane.

8. The adhesive composition of claim 1 having no glycol.

9. The adhesive composition of claim 1 having no ingredient in an amount sufficient to plasticize all of the acrylates/VA copolymer.

10. The adhesive composition of claim 1 having 0.001% to 30% of pigments, by weight of the total composition.
