Abstract

Provided are adhesive compositions that include an acrylate component and a charcoal component. The adhesive compositions are useful for adhering articles, for example, lashes or lash extensions to surfaces such as skin.

First claim

What is claimed is:

1. An adhesive composition for application of one or more beauty articles, comprising:
an acrylate component in an amount of about 10 percent by weight (wt %) to about 55 wt % based on a total weight of the adhesive composition;
a charcoal component comprising at least one of activated charcoal, acid washed activated charcoal, high purity activated charcoal, impregnated charcoal, pharmaceutical grade activated charcoal, acid-washed granular activated charcoal made from coconut shell or combinations thereof; and
a preservative in an amount of about 0.01 wt % to about 1.0 wt %,
wherein the preservative comprises phenoxyethanol and the acrylate component comprises an acrylate/ethylhexyl acrylate copolymer.

2. The adhesive composition of claim 1 , wherein the acrylate component comprises at least one of acrylates, polyacrylates, acrylamide polymers, alkyl acrylates, (meth)acrylates, acrylic acids, (meth)acrylic acid, acrylamide, (meth)acrylamide polymers, polymethacrylate, polymethylmethacrylate, C 1-6 hydroxyalkyl (meth)acrylates, C 1-6 alkoxy C 1-6 alkyl (meth)acrylates, polyoxyalkylene (meth)acrylates, C 1-6 alkylpolyoxyalkylene (meth)acrylates, C 8-22 alkyl (meth)acrylates, methyl(meth)acrylate, ethyl(meth)acrylate, propyl(meth)acrylate, butyl(meth)acrylate, isobutyl(meth)acrylate, pentyl(meth)acrylate, hexyl(meth)acrylate, 2-hydroxyethyl(meth)acrylate, 2-methoxyethyl(meth)acrylate, polyethyleneglycol (meth)acrylate, polyethyleneglycol methyl ether (meth)acrylate, polyethyleneglycol ethyl ether (meth)acrylate, octyl(meth)acrylate, 2-ethylhexyl(meth)acrylate, lauryl(meth)acrylate, stearyl(meth)acrylate, 2-ethylhexyl acrylate, copolymers thereof, quaternary salts thereof, ethylhexyl acrylate copolymer, ethylhexyl acrylate and acrylate copolymer, acrylate/ammonium methacrylate copolymer, acrylate/C 12-22 alkylmethacrylate copolymer, styrene/acrylate copolymer, acrylamide/acryloyldimethyltaurate copolymer, potassium acrylate/C 10-30 alkyl acrylate crosspolymer, sodium acrylate/C 10-30 alkyl acrylate crosspolymer, aminomethylpropanol-acrylate copolymer, glyceryl acrylate/acrylic acid copolymer, hydroxyethylacrylate/sodium acryloyldimethyl tau rate copolymer, sodium hydroxyethylacrylate/acryloyldimethyl taurate copolymer, styrene/acrylates/ammonium methacrylate copolymer, sodium polyacrylate, sodium polyacrylate starches, polyglyceryl methacrylates, ammonium acryloyldimethyltaurate/VP copolymer or combinations thereof.

3. The adhesive composition of claim 1 , wherein the charcoal component comprises at least one of a carbonaceous material derived from wood, bamboo, hardwood, peat, coal, coke, petroleum, bones, coconut shells, nutshells, coir, lignite or combinations thereof.

4. The adhesive composition of claim 1 , comprising the charcoal component in an amount of about 0.001 wt % to about 5 wt % based on a total weight of the adhesive composition.

5. The adhesive composition of claim 1 , wherein the charcoal component comprises a plurality of units comprising at least one of powder, particles, granules, extrudates, pellets or combinations thereof.

6. The adhesive composition of claim 1 , wherein the charcoal component comprises a plurality of units comprising a size of less than about 1 mm or comprising a mean size of about 1 mm.

7. The adhesive composition of claim 1 , further comprising water in an amount of about 1 wt % to about 90 wt % based on a total weight of the adhesive composition.

8. The adhesive composition of claim 1 , further comprising a colorant, wherein the colorant comprises at least one of carbon black, azo dye, quinophthalone dye, triphenylmethane dye, xanthene dye, iron oxide, iron hydroxide, titanium dioxide, sunset yellow dye, allura red dye, amaranth dye, koki neil red dye, azogeranin dye, tartrazine dye, brilliant black dye, canthaxanthin dye, patent blue dye, fast green dye, brilliant blue dye, acid green dye, erythrosine dye, quinoline yellow, indigotin, curcumin or combinations thereof.

9. The adhesive composition of claim 1 , wherein the preservative comprises at least one of phenoxyethanol, benzalkonium chloride, sodium dehydroacetate, benzyl alcohol, phenethyl alcohol, esters of p-hydroxybenzoic acid, imidazolidinyl urea, diazolidinyl urea, carboxylic acids or combinations thereof.

10. The adhesive composition of claim 1 , wherein the adhesive composition is free of a cyanoacrylate, latex, a formaldehyde or any combination thereof.

11. The adhesive composition of claim 1 , comprising a viscosity of about 10,000 cP to about 50,000 cP at 25° C.

12. The adhesive composition of claim 1 , comprising an adhesive strength of about 0.5 MPa to about 100 MPa.

13. An adhesive composition for application of one or more beauty articles, comprising:
an acrylate component in an amount of about 45 percent by weight (wt %) to about 55 wt % based on a total weight of the adhesive composition;
a charcoal component in an amount of about 0.001 wt % to about 2 wt %, wherein the charcoal component comprises at least one of activated charcoal, acid washed activated charcoal, high purity activated charcoal, impregnated charcoal, pharmaceutical grade activated charcoal, acid-washed granular activated charcoal made from coconut shell or combinations thereof;
a preservative in an amount of about 0.01 wt % to about 1.0 wt %; water in an amount of about 40 wt % to about 50 wt %; and
a colorant in an amount of about 1 wt % to about 4 wt %.
