Description

Composition for hair care

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

In general, human hair consists of a cuticle layer and three layers of cortex and medulla. The stratum corneum is the outermost layer that acts to surround the protective cortex. The surface of the stratum corneum that is not damaged by healthy hair is smooth and produces light refraction and acts to reduce the friction between the hair.

The hair is easily affected by the external environment, and more specifically, the hair is damaged by factors such as dry and cold wind, indoor heating and excessive combing, stress, insufficient nutrition, and lack of sleep. Moreover, recently, modern people regard hair as a fashion, and thus gradually increase hair dyeing, perming, discoloration, and the like, often performing hair application or excessive use of hair products or long-term use of a hair dryer, so that hair damage frequently occurs.

Damage to the hair according to various physical, chemical or environmental factors will cause damage to the stratum corneum of the hair, and dissolve proteins and lipids inside the hair, which will make the hair rough and lose luster, increase friction and make the hair easy to entangle, and Causes the hair to be easily cut or cracked at the end. Further, there is also a problem that the hair is detached due to loss of elasticity and the fluffiness is lost or the hair is thinned. In addition, damaged hair is difficult to repair, so it requires careful care.

As a result, consumer demand and preferences for hair care (improving hair) products that maintain hair shine and elasticity are increasing.

The existing hair care product enhances the appearance and feel of the hair, and includes a cationic surfactant or a cationic polymer in order to obtain a sustained effect, specifically, by adsorbing on the surface of the hair which is anionic due to damage The hair surface is improved to improve hair quality, and hair damage and static electricity which may occur in the future are suppressed, so that wet hair and dry hair can be more easily taken care of.

However, hair care products that currently use cationic substances only act on the surface of the hair, so the effect will be lost after shampooing. In particular, in the case of a thinned or roughened hair, the internal strength of the hair has been largely lowered, so that it is difficult to obtain a sufficient effect only by the modification of the surface of the hair.

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

In one example, Korean Patent Publication No. 2014-0090007 discloses that the surface of the hair is hydrophobized by the hair care composition comprising a compound having a reactive residue capable of forming a covalent bond with a specific residue of hair. Provides the effect of healthy hair traits while maximizing persistence.

The above patents have a certain degree of efficacy in improving hair quality, but their effects are insufficient, and they are limited or have a strict manufacturing process due to considerations for human safety, processing stability, and the like. . Therefore, it is more necessary to develop a new composition for hair care which exhibits excellent hair care effect and endurance.

[Table 1] Experimental Example 1. For the application of the hair (leave-on) state evaluation

In order to evaluate the hair care effect of the composition for hair care manufactured in the above Examples and Comparative Examples, and applying the manufactured composition to the hair, the tensile strength and surface friction of the hair were as follows. Force and hair elasticity were measured.

At this time, a bundle of hair was washed with a basic shampoo (manufactured by Korea Phoenix Co., Ltd.) having no hair care function, and after one minute of shampooing and two minutes of drying, 0.3 g of the above examples and comparative examples were applied. A composition for hair care. 1 ) Anti-tension

The tensile strength of one of the hairs of the above-described examples and comparative examples was measured using a multi-functional hair measuring device MTT175 (manufactured by DiaStron). The above-mentioned anti-tension refers to the force applied to the hair when the hair is stretched to the break, and the larger the value, the greater the strength and health of the hair. The results obtained here are shown in Fig. 1. 2 ) Surface friction

The surface friction of one of the hairs of the above-described examples and comparative examples was measured using a multi-functional hair measuring device MTT175 (manufactured by DiaStron Co., Ltd.). The above surface friction means a value which compares the roughness when passing through the surface of the hair, and the smaller the value, the higher the smoothness of the hair. The results obtained here are shown in Fig. 2. 3 ) Hair elasticity

A bundle of hairs to which the above-described examples and comparative examples were applied was fixed in a semicircular type having a height of 1.5 cm. Next, application was carried out by using a push-pull piston with a force of 0.001 N per second from 0.001 N. In this case, the force is applied from the apex of the semicircular shape toward the vertical direction, and the pressure is measured while pressurizing the measuring member to which the push-pull piston is attached. After the force of the semicircular portion of the collapsed hair was measured, this procedure was repeated 30 times. In this case, the hair elasticity means the force supported by the hair when the hair is bent into a semicircular shape, and the greater the strength of the support, the greater the elasticity of the hair. The results obtained here are shown in Fig. 3.
