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.

First claim

What is claimed is:

1. A composition for hair modification comprising:
a carbodiimide-based compound represented by Chemical Formula 3 below; and
a hair-modifying component,

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

2. The composition for hair modification 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.

3. The composition for hair modification according to claim 1 , wherein the hair-modifying component has a carboxyl group, a hydroxyl group, a phosphate group, or an amine group in a molecule thereof.

4. The composition for hair modification according to claim 1 , wherein the hair-modifying component has a functional group capable of covalently bonding with a protein residue in a hair surface.

5. The composition for hair modification according to claim 4 , 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.

6. The composition for hair modification according to claim 1 , wherein the carbodiimide-based compound is included at a content of 0.0001 to 10 parts by weight with respect to 100 parts by weight of the entire composition.

7. The composition for hair modification 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 are encapsulated; or in the form of two distinct formulations in which the carbodiimide-based compound and the hair-modifying component are separated from each other.

8. A hair care product comprising the composition for hair surface modification according to claim 1 .
