Description

Composition for hair care

The present invention relates to a composition for hair care, which exhibits excellent hair care effect and durability.

Generally speaking, human hair is composed of three layers: cuticle layer, cortex, and medulla. The cuticle is the outermost layer and plays the role of surrounding and protecting the cortex. The surface of the undamaged cuticle of healthy hair is smooth, refracts light and reduces friction between hairs.

Hair is easily affected by the external environment, more specifically, hair is damaged by factors such as dry and cold wind, indoor heating and excessive grooming, stress, nutritional deficiency, and lack of sleep. In addition, recently, modern people regard hair as a fashion, so hair coloring, perming, bleaching, etc. are often carried out, such as frequent hair treatments, excessive use of hair products, and long-term use of hair dryers, so hair damage occurs frequently.

Hair damage due to various physical, chemical or environmental factors will cause damage to the cuticle of the hair, and dissolve the protein and lipids inside the hair, making the hair rough and dull, increasing the friction and making the hair easy to tangle, and A phenomenon in which the hair is prone to cutting or splitting at the ends. In addition, there is also a problem that hair falls out due to loss of elasticity, loss of fluffy feeling or thinning of hair. In addition, damaged hair is difficult to repair, so it needs careful care at ordinary times.

Therefore, consumers are increasingly demanding and preferring hair care (hair quality improvement) products that can keep hair shiny and elastic.

Existing hair care products improve the look and feel of the hair and include cationic surfactants or cationic polymers for a sustained effect, specifically by adsorbing on the damaged hair surface which is anionic It improves the surface of the hair, thereby improving the quality of the hair, and inhibits future hair damage and static electricity, making it easier to care for wet and dry hair.

However, the current hair care products using cationic substances only act on the surface of the hair, so they will lose their effect after shampooing. In particular, in the case of thinned or roughened hair, the internal strength of the hair has been greatly reduced, so that it is difficult to obtain a sufficient effect only by modification of the hair surface.

There have been many attempts to improve hair quality and increase staying power by changing the composition of cationic surfactants, higher alcohols, oils, etc. or developing novel compounds.

In one example, Korean Laid-Open Patent No. 2014-0090007 discloses that by hydrophobizing the surface of the hair due to the fact that the hair conditioner composition includes a compound having a reactive residue that can form a covalent bond with a specific residue of the hair, it can Provides the effect of healthy hair properties while maximizing permanence.

The above-mentioned patents have a certain degree of effectiveness in improving hair quality, but the effect is not sufficient, and due to concerns about human safety (safety), processing stability (stability), etc., the application is limited or has a strict manufacturing process . Therefore, development of a new composition for hair care which exhibits an excellent hair care effect and staying power is actually more demanded.

Compositions for hair care. 1 ) Tension resistance

Tensile resistance of one hair among the hairs of the above-mentioned Examples and Comparative Examples was measured using a multifunctional hair tester MTT175 (manufactured by Diastron). The above-mentioned tensile strength refers to the force exerted on the hair when the hair is stretched so tightly that it breaks, and the larger the value, the stronger the hair and the healthier it is. The results obtained here are shown in FIG. 1 . 2 ) Surface friction

The surface friction of a bundle of hairs coated with the hairs of the above Examples and Comparative Examples was measured using a multifunctional hair tester MTT175 (manufactured by DiaStron). The above-mentioned surface friction means a numerical value for comparison of roughness when passing through the surface of hair, and the smaller the numerical value, the higher the smoothness of the hair. The results to be obtained here are shown in FIG. 2 . 3 ) hair elasticity

A bundle of hairs coated with the above-mentioned examples and comparative examples was fixed in a semicircular shape with a height of 1.5 cm. Next, application was performed with a force of 0.001 N increased every second from 0.001 N using a push-pull piston. In this case, the above-mentioned force is applied from the apex of the semicircle toward the vertical direction, and the pressure is measured while the measuring member equipped with the above-mentioned push-pull piston is pressurized. After measuring the strength of the semicircular part of the collapsed hair, this procedure was repeated 30 times. In this case, hair elasticity refers to the force supported by the hair when the middle part is pressed after the hair is bent into a semicircular shape, and the greater the support force, the greater the elasticity of the hair. The results to be obtained here are shown in FIG. 3 .

Compared with the hair treated with the comparative example, as shown in FIGS. 1 to 3 , the hair treated with the composition of the example has increased tensile strength and elasticity, and reduced surface friction. In particular, in the cases of Example 4 and Example 7 in which maleic acid and malic acid were used, respectively, it was found that excellent tension resistance and hair elasticity were exhibited, and at the same time, low frictional force was exhibited.
