Description

Hair Care Composition

This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0124305 filed on September 27, 2016 and Korean Patent Application No. 10-2017-0100148 filed on August 8, 2017. All content disclosed in the literature is included as part of this specification.

The present invention relates to a hair care composition exhibiting excellent conditioning effect and persistence.

Human hair is generally composed of three layers: the cuticle layer, the cortex, and the medulla. The cuticle layer is the outermost layer that surrounds and protects the cortex, while healthy hair's intact cuticles have a smooth surface, refract light, and reduce friction between hairs.

The hair is easily affected by the external environment, and in particular, the hair is damaged by factors such as cold and dry wind, indoor heating and excessive combing, stress, malnutrition and sleep deprivation. In addition, as modern people recognize hair as a fashion, they frequently receive hair treatment such as dyeing, perming, and discoloring, excessive use of hair beauty products, or long-term use of hair dryers. Occurs frequently.

Hair damage caused by various physical, chemical, or environmental factors can cause loss of the cuticle layer of the hair, and protein and lipids in the hair can be eluted, resulting in roughness, loss of shine, and increased friction, which leads to tangled hair easily. Easily cut or cracked ends occur. In addition, there is a problem that the volume is lost or the hair thinner due to sagging hair due to loss of elasticity. In addition, damaged hair cannot be repaired again, so you need to take care of it on a regular basis.

Therefore, consumers' demands and preferences for conditioning (hair condition improvement) products that can maintain shiny and elastic hair are increasing day by day.

Existing conditioning products include cationic surfactants or cationic polymers to improve the appearance and feel of the hair and to achieve a lasting effect, and specifically, they are adsorbed on the surface of the anionic hair due to damage and thus improve the hair surface. It improves the condition and suppresses future hair damage and static electricity, making it easier to manage both wet and dry hair.

However, current conditioning products using cationic materials act only on the surface of the hair and lose their effect after hair cleaning. In particular, in the case of thinned or rough hair, the strength inside the hair is much lowered, so that it is difficult to obtain a sufficient effect only by modifying the hair surface.

There have been many attempts to improve the hair condition and improve the sustainability by varying the composition of cationic surfactants, higher alcohols, oils and the like or by developing new compounds.

For example, Korean Patent Application Publication No. 2014-0090007 includes a compound having a reactive moiety capable of forming a covalent bond with a specific moiety of hair in a treatment composition, thereby providing a property of healthy hair by hydrophobizing the surface of the hair. It also discloses that it can maximize its sustainability.

The patent has a certain effect on improving the hair condition, but the effect is not sufficient, the application is limited or difficult to manufacture due to concerns about human safety, processing stability (stability) and the like. Therefore, there is a further need for the development of a new hair care composition showing excellent conditioning effects and sustainability.

Hereinafter, the present invention will be described in more detail.

As used herein, the term "conditioning effect" refers to preventing the restoration of damaged hair or damage to healthy hair, and specifically, thickening the hair or improving tensile strength to strengthen the hair, and softening, moistening, smoothing, and elasticity of the hair. It gives a sense of volume, which means maintaining a healthy hair condition.

The present invention provides a hair care composition having excellent conditioning effects and a strong holding power.

Interest in appearance is increasing day by day due to the diversity of modern society and the improvement of cultural level. In particular, since hair is an important part of an individual's appearance as much as a face, hair treatments such as perming and dyeing are common. However, hair is easily damaged by various physical, chemical or environmental factors due to frequent hair treatment, styling and the like. Once damaged hair is incapable of restoring itself back to its original healthy state because it is incapable of self-healing and the extent of damage is accelerated over time, the use of conditioning products is required to maintain hair healthier.

Damaged hair is damaged by the cuticle layer on the surface is eluted protein and lipids inside the hair to be porous. This causes the hair to become thinner and rougher, lose shine and increase friction, resulting in splitting and eventually breaking of the hair ends. However, conventional conditioning products do not provide a fundamental solution to improving the condition of the hair because they are intended to improve the surface properties of the hair, and provide only a short-term effect temporarily until the next cleaning after use on the hair, which requires reprocessing after cleaning. There is a hassle.

Accordingly, the present invention provides a hair care composition comprising an aliphatic dibasic acid compound and an aliphatic diamine compound capable of forming ionic bonds with the constituents of the hair by reacting with the inside or surface of the hair in order to secure excellent hair conditioning effect and sustainability. To present.

Specifically, the hair care composition according to the present invention includes an aliphatic dibasic acid compound of C2 to C4 and an aliphatic diamine compound of C2 to C6.

The C2 to C4 aliphatic dibasic acid compound is a compound having two carboxylic acid groups at the end of the C2-4 aliphatic hydrocarbon chain. The aliphatic hydrocarbon chain can then be saturated or unsaturated. In addition, one or more hydrogen atoms included in the aliphatic hydrocarbon chain may be optionally substituted with one or more substituents.

Generally, damaged hair is anionic due to the loss of fatty acids on the hair surface, unlike normal hair. In this case, the C2 to C4 aliphatic dibasic acid compound forms an ionic bond with the inside of the hair showing anionicity due to damage, thereby filling the damaged part of the hair to strengthen the hair to obtain a conditioning effect as well as providing excellent ionic bond. To ensure that the effect is maintained over the long term.

For example, the C2 to C4 aliphatic dibasic acid compound is succinic acid, aspartic acid, maleic acid, maleic acid, malic acid, tartaric acid, fumaric acid ), Glutaric acid, glutamic acid, glutaconic acid, 1,3-acetonedicarboxylic acid, adipic acid and At least one selected from the group consisting of muconic acid can be used. Preferably, at least one selected from the group consisting of maleic acid, malic acid, glutamic acid and 1,3-acetonedicarboxylic acid can be used. More preferably, at least one selected from the group consisting of maleic acid and malic acid can be used.

The C2 to C4 aliphatic dibasic acid compound may be directly synthesized through a method commonly performed in the art or may be used by purchasing a commercially available product.

The C2 to C4 aliphatic dibasic acid compound may be used in an amount of 0.3 to 20% by weight, preferably 1 to 10% by weight, based on 100% by weight of the total composition for hair care composition. When the content of the aliphatic dibasic acid compound of the C2 to C4 is less than the above range, there is a problem in that the hair damage recovery effect is difficult to appear, on the contrary, when the content exceeds the above range, formulation is difficult and the scalp is likely to be irritated.

The C2 to C6 aliphatic diamine compound is a compound having two amine groups at the aliphatic hydrocarbon chain terminal having 2 to 6 carbon atoms, and reacts with the dibasic acid compound described above to serve to strengthen the overall hair binding force. At this time, since the reaction is made by forming an ionic bond, it does not fall off during general cleaning due to shampoo or soap, and even after the cleaning, it can be expected to have an additional effect of strong semipermanent care.

The C2 to C6 aliphatic diamine compound is tetrahydroxypropyl ethylenediamine, spermidine, histidine, histidine, ornithine, arginine, 2,6-bis- ( Dimethylaminomethyl) -cyclohexanone dihydrochloride (2,6-BIS- (dimethylaminomethyl) -cyclohexanone dihydrochloride), lysine and 1,6-hexadiamine 1 or more types can be used. Preferably, at least one selected from the group consisting of tetrahydroxypropyl ethylenediamine, arginine, lysine and 1,6-hexadiamine can be used. More preferably, one or more types selected from the group consisting of tetrahydroxypropyl ethylenediamine and arginine can be used.

The aliphatic diamine compound of C2 to C6 may be directly synthesized or purchased and used commercially.

The aliphatic diamine compound of C2 to C6 may be used in 0.3 to 20% by weight, preferably 1 to 10% by weight based on 100% by weight of the total composition for hair care composition. When the content of the aliphatic dibasic acid compound of C2 to C4 is less than the above range, the effect of strengthening the hair binding force is insufficient, on the contrary, when the content exceeds the above range, the increase of the effect due to the increase of the content is very weak and adversely affects the formulation. Can be.

Experimental Example  One. live When in a leave-on state Evaluation of hair

In order to evaluate the conditioning effect of the hair care compositions prepared in Examples and Comparative Examples, the prepared composition was treated to the hair, and then the tensile strength, the surface friction force, and the hair elasticity of the hair were measured by the following method.

The hair used at this time was washed with tress (made by Phoenix Korea) hair using a basic shampoo without conditioning function, rinsed for 1 minute and dried for 2 minutes, and then 0.3 g of the hair care composition of Examples and Comparative Examples. Applied.

1) tensile strength

The tensile strength of one strand of hair was measured with the hair to which the said Example and the comparative example were apply | coated using the multipurpose hair measuring apparatus MTT175 (made by DiaStron company). The tensile strength refers to the weight of the force applied to the hair until the hair is pulled out and the greater the value, the stronger and healthier the hair. The results obtained at this time are shown in FIG.

2) surface friction

The hair to which the said Example and the comparative example were apply | coated was measured for the surface friction force of the hair tress using the multipurpose hair measuring machine MTT175 (made by DiaStron company). The surface frictional force is a value comparing the roughness when passing through the surface of the hair, and the smaller the value, the smoother the hair. The results obtained at this time are shown in FIG.

3) hair elasticity

The hair tress to which the examples and the comparative examples were applied was fixed in an arch form having a height of 1.5 cm. It was then pressurized using the push-pull piston with a force of 0.001 N per second starting at 0.001 N. At this time, the force was applied in the vertical direction from the peak of the arch shape, the pressure was measured at the same time as the pressure in the measuring member equipped with the push-pull piston. The force at the point where the arch of the hair collapses was measured and then repeated 30 times. At this time, the hair elasticity refers to the strength of the hair when the hair is bent in an arch shape and the center point is pressed. The greater the strength, the greater the elasticity of the hair. The results obtained at this time are shown in FIG.

As shown in Figures 1 to 3, the hair treated with the composition of the Example increased the tensile strength and elasticity compared to the hair treated with the comparative example, the surface friction was reduced. In particular, it can be seen that Examples 4 and 7 using maleic acid and maleic acid, respectively, exhibited low frictional force with excellent tensile strength and hair elasticity. From these results, it can be seen that the composition according to the present invention has an excellent conditioning effect upon rib-on application.

Experimental Example  2. After cleaning Evaluation of hair

The tress hair treated with the compositions of Examples and Comparative Examples in Experimental Example 1 was washed using a basic shampoo without conditioning function, rinsed for 1 minute, dried for 2 minutes, and then tested for tensile strength, surface friction, and hair elasticity of the hair. It measured in the same manner as in Example 1. The obtained results are shown in FIGS. 4 to 6.

4 to 6, in the case of the hair treated with the composition according to the present invention, it can be seen that the degree of tensile strength improvement, frictional force reduction, and hair elasticity increase are maintained at a level similar to that of Experimental Example 1, even after washing. Therefore, it can be seen that the composition according to the present invention maintains the same level of conditioning effect even after washing.
