Description

Cosmetic composition for repairing damaged hair Technical Field The present invention relates to a hair cosmetic composition containing dibromoacetamido-ethyl glycol (Bis-Bromoacetylaminoethyl Glycol) as an active ingredient, which is harmless to the human body, can repair damaged hair, and is used in the form of a shampoo, a conditioner, an essence, a cream, an essential oil, and the like. Background Hair is a fiber bundle in which about 18 amino acids are repeatedly peptide-bonded and millions of polypeptides are regularly entangled. The peptide Bond is a Main chain Bond (Main Bond), has a very firm molecular structure, and is firmly fixed along the transverse and horizontal directions through disulfide bonds, salt bonds and hydrogen bonds. Salt bonds are also called ionic bonds, as acidic amino acids having a carboxyl group in the side chain such as aspartic acid (ASPARTIC ACID) or glutamic acid (Glutamic Acid), and basic amino acids having two amino groups and one carboxyl group such as Lysine (Arginine) and histidine (Histidin), which form ionic bonds between the basic amino acids by intermolecular forces between negative charges and positive charges, and have relatively weak binding forces. Salt bonds are easily broken by the change of the pH value, and are repaired again when the pH is restored to be normal. Although the strength of salt bonds is significantly weaker than disulfide bonds, it is about 30% of the hair strength due to the large number of bonds. Hydrogen bonding is a very weak physical lateral bond between positive and negative charges generated by the electronegativity difference of hydrogen and oxygen, which is easily broken by water or heat, and re-forms in case of drying or cooling. Disulfide bonds are formed by the bonding of two adjacent cysteine hydrophobic groups to each other, and are very strong bonds, also called S-S bonds (bond), as covalent bonds between sulfur elements in the form of-S. However, disulfide bonds having very strong binding force may be easily deformed or damaged by strong heat or chemical treatments such as permanent waving and hair dye. That is, the Side Bond (Side Bond) is easily affected by chemical action, and the Bond is broken by chemical treatments such as permanent waving, dyeing, and bleaching, and part of protein is lost, eventually resulting in hair damage. As described above, the side chain bonds that determine the elasticity and strength of hair have reversible properties of repeated breakage and recombination due to water, pH, and chemical oxidation/reduction reaction, but are partially lost and cannot be recombined by repeated chemical treatment and intense heat treatment and chemical treatment, and may cause permanent damage to hair. The prior art of cosmetic compositions for repairing hair from such permanent damage includes, for example, korean laid-open patent 2021-0081672 (patent document 1). The invention relates to a cosmetic composition for repairing damaged hair, which comprises 75 to 94 weight percent of keratin or peptide with the molecular weight of 520 to 3000 daltons, 5 to 20 weight percent of coconut oil and 1 to 5 weight percent of citric acid, and provides the effects of glossiness, lubricity, moisture retention, elasticity of modeling and the like. However, it is difficult to expect hair side chain bond restoration such as disulfide bond by adding keratin or peptide hair constituent substances, and therefore hair restoration effect is very limited. Therefore, there is an urgent need for research into cosmetic compositions for damaged hair restoration that can restore damaged hair to an original healthy state due to various factors such as physical, chemical, or environmental factors.
