Keratin Treatments
The present disclosure relates generally to keratin treatments. More particularly, but not by way of limitation, present disclosure relates to skin, nail, hair, and eyelash treatments comprising a keratin-peptide/dendrimer composition for ameliorating a condition of a nail. The keratin-peptide can be keratin or hydrolyzed or partially hydrolyzed keratin.
1 . A keratin restorative composition comprising:
a keratin-peptide; and
a dendrimer.
2 . The keratin restorative composition according to claim 1 , wherein a weight ratio of keratin-peptide to dendrimer is from about 4:1 to about 1:60.
3 . The keratin restorative composition according to claim 1 , wherein said keratin-peptide comprises a partially-hydrolyzed keratin.
4 . The keratin restorative composition according to claim 1 , comprising a mixture of the keratin-peptide and the dendrimer.
5 . The keratin restorative composition according to claim 1 , wherein the keratin-peptide and the dendrimer are associated.
6 . The keratin restorative composition of claim 5 , wherein the keratin-peptide and the dendrimer are associated by an interaction selected from the group consisting of van der Waal's interaction, dipole-dipole interaction, covalent bonding, ionic bonding and hydrogen bonding.
7 . The keratin restorative composition according to claim 1 , wherein the dendrimer comprises a functional group that interacts react with the keratin-peptide.
8 . The keratin restorative composition according to claim 1 , wherein the dendrimer comprises a functional group selected from the group consisting of OH, NH 2 , SH, and COOH.
9 . The keratin restorative composition according to claim 1 , wherein the keratin-peptide remains at least partially exposed for interaction or reaction with keratin of a keratinaceous substrate and the dendrimer functional group extends unidirectionally from the keratin-peptide constituent.
10 . The keratin restorative composition according to claim 1 , wherein the dendrimer comprises at least one hydrophobic group.
11 . The keratin restorative composition according to claim 10 , wherein the hydrophobic group includes a linear or branched C 6 -C 20 carbon chain optionally substituted with one or more functional groups.
12 . The keratin restorative composition according to claim 10 , wherein the dendrimer comprises a compound having the structure
wherein R is selected from the group consisting of OH, NH 2 , SH, COOH, OR′, NHR′, SR′H, COOR′ and NR′ 2 ;
R′ is a hydrophobic group; and
the dendrimer contains at least one hydrophobic group.
13 . The keratin restorative composition according to claim 1 , further comprising a solvent.
14 . The keratin restorative composition according to claim 1 , further comprising one or more components selected from the group consisting of a film forming polymer, a reactive (meth)acrylate, an epoxidized esterified plant oil, a polyhedral oligomeric silsesquioxane, and a colorant.
15 . A method for ameliorating a condition of a keratinaceous substrate comprising:
applying to the keratinaceous substrate a keratin restorative composition comprising:
a keratin-peptide; and
a dendrimer.
16 . The method of claim 15 , wherein the condition is selected from the group consisting of nail delamination, brittleness, cracking, chipping, splitting, dryness, and texturing.
17 . The method of claim 15 , wherein the keratinaceous substrate is selected from skin, nails and hair.
18 . A method of making a keratin restorative composition comprising mixing a keratin-peptide and a dendrimer.
19 . The method of claim 18 , wherein mixing comprises chemically reacting.
20 . The method of claim 18 , wherein mixing comprises forming a covalent, ionic, or hydrogen bond.
