Abstract

The present invention relates to a composition for surface modification. The composition for surface modification according to the present invention contains a particular carbodiimide-based compound, thus forms a covalent bond without damaging skin, hair, or fabric, and semipermanently provides desired skin or hair surface modification effects or fabric care effects.

Claims (21)

1. A method for modifying the surface of hair or skin, comprising:

preparing a composition for hair or skin modification, wherein the composition comprises a carbodiimide-based compound represented by Chemical Formula 2 below, and a hair-modifying component or a skin-modifying component, wherein the hair-modifying component or the skin-modifying component does not include a peptide; and

treating hair or skin with the composition for hair or skin modification:

wherein A each independently represents a monomer selected from structures listed below,

m is an integer ranging from 1 to 100, and

n is an integer ranging from 1 to 1,000,

wherein * denotes a connecting position.

2. A method for modifying the surface of hair or skin, comprising:

preparing a composition for hair or skin modification, wherein the composition comprises a carbodiimide-based compound represented by Chemical Formula 3 below, and a hair-modifying component or a skin-modifying component, wherein the hair-modifying component or the skin-modifying component does not include a peptide; and

treating hair or skin with the composition for hair or skin modification:

wherein n is an integer ranging from 1 to 130, and m is an integer ranging from 1 to 20.

3. The method for modifying the surface of hair or skin according to claim 1 , wherein the hair-modifying component is a component for antioxidation; conditioning; blocking ultraviolet rays; imparting fragrance; applying a dye; bioconjugation; inhibiting bacteria; stimulating hair growth; or stimulating hair regrowth, and the skin-modifying component is a component for antioxidation; conditioning; moisturizing; whitening; blocking ultraviolet rays; imparting fragrance; preventing or improving a wrinkle; keratin care; preventing or improving dandruff/itching; stimulating hair growth; preventing acne or inhibiting bacteria; suppressing body odor; atopic dermatitis care; pore care; epilation; fingernail and toenail care; or bioconjugation, or a component in the form of a dye or a powder.

4. The method for modifying the surface of hair or skin according to claim 1 , wherein the hair-modifying component or the skin-modifying component has a carboxyl group, a hydroxyl group, a phosphate group, or an amine group in a molecule thereof.

5. The method for modifying the surface of hair or skin according to claim 1 , wherein the hair-modifying component or the skin-modifying component has a functional group capable of covalently bonding with a protein residue in a skin surface.

6. The method for modifying the surface of hair or skin according to claim 5 , wherein the functional group capable of covalently bonding with a protein residue is one or more selected from the group consisting of imidoesters, aryl azides, diazirines, hydroxymethyl phosphine, pentafluorophenyl esters, pyridyl disulfide, sulfo-hydroxysuccinimide esters, alkoxyamines, hydrazides, haloacetyls, azide, carbonates, aldehydes, propionaldehyde, butylaldehyde, nitrophenyl carbonate, aziridines, isocyanate, thiocyanate, epoxides, tresylates, succinimide, hydroxysuccinimidyl esters, imidazole, oxycarbonylamidazole, imines, thiols, maleimide, vinyl sulfone, ethyleneimine, thioethers, acrylonitrile, acrylic or methacrylic acid ester, disulfides, and ketones.

7. The method for modifying the surface of hair or skin according to claim 1 , wherein the composition is prepared in the form of a single formulation in which the carbodiimide-based compound and the hair-modifying component or the skin-modifying component are encapsulated; or in the form of two distinct formulations in which the carbodiimide-based compound and the hair-modifying component or the skin-modifying component are separated from each other.

8. The method for modifying the surface of hair or skin according to claim 2 , wherein the hair-modifying component is a component for antioxidation; conditioning; blocking ultraviolet rays; imparting fragrance; applying a dye; bioconjugation; inhibiting bacteria; stimulating hair growth; or stimulating hair regrowth, and the skin-modifying component is a component for antioxidation; conditioning; moisturizing; whitening; blocking ultraviolet rays; imparting fragrance; preventing or improving a wrinkle; keratin care; preventing or improving dandruff/itching; stimulating hair growth; preventing acne or inhibiting bacteria; suppressing body odor; atopic dermatitis care; pore care; epilation; fingernail and toenail care; or bioconjugation, or a component in the form of a dye or a powder.

9. The method for modifying the surface of hair or skin according to claim 2 , wherein the hair-modifying component or the skin-modifying component has a carboxyl group, a hydroxyl group, a phosphate group, or an amine group in a molecule thereof.

10. The method for modifying the surface of hair or skin according to claim 2 , wherein the hair-modifying component or the skin-modifying component has a functional group capable of covalently bonding with a protein residue in a hair surface.

11. The method for modifying the surface of hair or skin according to claim 10 , wherein the functional group capable of covalently bonding with a protein residue is one or more selected from the group consisting of imidoesters, aryl azides, diazirines, hydroxymethyl phosphine, pentafluorophenyl esters, pyridyl disulfide, sulfo-hydroxysuccinimide esters, alkoxyamines, hydrazides, haloacetyls, azide, carbonates, aldehydes, propionaldehyde, butylaldehyde, nitrophenyl carbonate, aziridines, isocyanate, thiocyanate, epoxides, tresylates, succinimide, hydroxysuccinimidyl esters, imidazole, oxycarbonylamidazole, imines, thiols, maleimide, vinyl sulfone, ethyleneimine, thioethers, acrylonitrile, acrylic or methacrylic acid ester, disulfides, and ketones.

12. The method for modifying the surface of hair or skin according to claim 2 , wherein the composition is prepared in the form of a single formulation in which the carbodiimide-based compound and the hair-modifying component or the skin-modifying component are encapsulated; or in the form of two distinct formulations in which the carbodiimide-based compound and the hair-modifying component or the skin-modifying component are separated from each other.
