Description

COMPOSITION FOR HAIR CARE [0001]

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

In general, human hair consists of three layers: a cuticle layer, a cortex, and a medulla. The cuticle layer is the outermost layer that protects the cortex and protects the healthy hair from damage. The surface of the cuticle is smooth, refracting the light, and reducing the friction between the hair.

The hair is easily affected by the outside environment, and the hair is damaged due to factors such as cold and dry wind, indoor heating and excessive combing, stress, malnutrition and lack of sleep. In addition, recently, modern people perceive hair as a fashion, and there is an increasing tendency to frequently perform hair treatments such as dyeing, perming, discoloring, excessive use of hair cosmetic products, or use of hair dryers for a long time, It occurs frequently.

If the hair is damaged by various physical, chemical, or environmental factors, it will cause the loss of the cuticle layer of the hair, and the protein and lipid in the hair will be eluted and the hair will become rough and lose its gloss, friction will increase, It is easily cut or the end is cracked. In addition, there is also a problem that the volume is lost or the hair becomes thin due to hair loss due to loss of elasticity. In addition, damaged hair will not be restored again, so care must be taken in daily care.

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

Conventional conditioning products include cationic surfactants or cationic polymers to improve the appearance and feel of hair and to obtain sustained effects. Specifically, they are adsorbed on the surface of an anionic hair due to damage, It improves the condition and makes it easier to manage both wet and dry hair in the future by suppressing hair damage and static electricity.

However, at present, a conditioning product using a cationic material only works on the surface of the hair, so that the effect is lost after the hair cleansing. Particularly, in the case of thinned or rough hair, the strength of the inside of the hair is greatly reduced, and it is difficult to obtain sufficient effect only by modifying the hair surface.

Accordingly, there have been various attempts to improve the hair condition and improve the sustaining ability by changing the composition of cationic surfactant, higher alcohol, oil, etc. or developing new compounds.

Korean Patent Laid-Open Publication No. 2014-0090007, for example, discloses a treatment composition comprising a compound having a reactive moiety capable of forming a covalent bond with a specific residue of a hair to hydrophilize the surface of hair to provide a property of healthy hair Thereby maximizing the sustainability.

Although the above-mentioned patent has some efficacy to improve the hair condition, its effect is not sufficient and the application is restricted or the manufacturing process is difficult due to concerns about safety of human body and stability of processing. Therefore, there is a further need for the development of a new composition for hair care which shows excellent conditioning effect and sustained power.

Korean Patent Publication No. 2014-0090007 (2014.07.16), a semi-permanent moisturizing treatment agent for forming a hydrophobic surface

Accordingly, the present inventors have conducted various studies to solve the above-mentioned problems. As a result, when the composition for hair care contains specific dibasic acid compound and diamine compound, the binding force to the inside and the inside of the hair is improved, However, it is confirmed that the effect is maintained in the long term.

Accordingly, an object of the present invention is to provide a composition for hair care having excellent hair conditioning effect and efficacy retention.

In order to achieve the above object, the present invention provides a composition for hair care comprising an aliphatic dibasic acid compound of C2 to C4 and an aliphatic diamine compound of C2 to C6.

The aliphatic dibasic acid compound of C2 to C4 may be selected from the group consisting of succinic acid, aspartic acid, maleic acid, malic acid, tartaric acid, fumaric acid, glutaric acid, glutamic acid, glutaconic acid, 1,3-acetone dicarboxylic acid, adipic acid, Acetic acid, and citric acid.

The C2 to C6 aliphatic diamine compound is selected from the group consisting of tetrahydroxypropylethylenediamine, spermidine, histidine, ornithine, arginine, 2,6-bis- (dimethylaminomethyl) -cyclohexanone dihydrochloride, Hexadiamine, and 6-hexadiamine.

The C2 to C4 aliphatic dibasic acid compound is contained in an amount of 0.3 to 20% by weight based on 100% by weight of the total composition for hair care.

The C2 to C6 aliphatic diamine compound is contained in an amount of 0.3 to 20% by weight based on 100% by weight of the total hair care composition.

The composition for hair care according to the present invention includes a specific dibasic acid compound and a diamine compound to effectively form damaged hair by forming a strong ionic bond with the inside and the inside of the hair and exhibits a semi-permanent hair reinforcing effect. It can be widely applied as a product.

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

In the present specification, the term " conditioning effect " refers to preventing the recovery of damaged hair or damage to healthy hair. Specifically, hair is strengthened by increasing the thickness of hair or tensile strength, and softness, moistness, smoothness, , And a sense of volume means that the state of healthy hair is maintained.

The present invention provides a composition for hair care having excellent conditioning effect and high holding power.

Due to the diversity of modern society and the improvement of the cultural level, interest in appearance is increasing day by day. Particularly, since the hair occupies an important part of the individual's appearance as a face, hair treatments such as permanent hair dyeing and the like are common. However, hair is easily damaged by various physical, chemical or environmental factors such as frequent hair treatment, styling, and the like. Once damaged hair is not self-healing, it is not only restorable to its original healthy state, but also the degree of damage is accelerated over time, requiring the use of conditioning products to maintain hair healthier.

In damaged hair, the cuticle layer on the surface is damaged, so that proteins and lipids in the hair are eluted and become porous. As a result, the hair becomes thin and rough, loses its gloss and friction increases, resulting in the ends of the hair being split and eventually being cut off. However, conventional conditioning products are not a fundamental solution to the improvement of the hair condition because they are intended to improve the surface characteristics of the hair, and they provide temporary short-term effects only until the next cleaning after use in the hair. There is a hassle.

Accordingly, the present invention provides a composition for hair care comprising an aliphatic dibasic acid compound and an aliphatic diamine compound capable of reacting with the inside or the surface of the hair to form ionic bonds with the constituents of hair in order to secure superior hair conditioning effect and long- .

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

The C2 to C4 aliphatic dibasic acid compound is a compound having two carboxylic acid groups at the terminal of the aliphatic hydrocarbon chain having 2 to 4 carbon atoms. Wherein the aliphatic hydrocarbon chain may be saturated or unsaturated. The at least one hydrogen atom contained in the aliphatic hydrocarbon chain may be optionally substituted with one or more substituents.

Unlike normal hair, damaged hair generally exhibits anion due to fatty acid loss on the hair surface. At this time, the aliphatic dibasic acid compound of C2 to C4 forms an ionic bond with the inside of the hair which shows anion due to damage, thereby satisfying the conditioning effect by strengthening the hair by filling the damaged part of the hair, So that the effect can be maintained over the long term.

For example, the C2 to C4 aliphatic dibasic acid compound may be selected from the group consisting of succinic acid, aspartic acid, maleic acid, malic acid, tartaric acid, fumaric acid ), Glutaric acid, glutamic acid, glutaconic acid, 1,3-acetonedicarboxylic acid, adipic acid and the like. And muconic acid may be used. Preferably, at least one selected from the group consisting of maleic acid, malic acid, glutamic acid and 1,3-acetone dicarboxylic 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 can be synthesized directly by a method commonly used in the art, or a commercially available product can be purchased and used.

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. If the content of the C2 to C4 aliphatic dibasic acid compound is less than the above range, there is a problem that the effect of recovering hair damage is difficult to be exhibited. On the other hand, if the content exceeds the above range, formulation is difficult and the scalp is likely to cause irritation.

The C2 to C6 aliphatic diamine compound is a compound having two amine groups at the terminal of the aliphatic hydrocarbon chain having 2 to 6 carbon atoms, and reacts with the dibasic acid compound described above to further strengthen the binding force of the hair. At this time, since the reaction is performed by forming ionic bonds, it does not come off well during general cleaning due to shampoo, soap, etc., and it can be expected to have an additional effect of semi-permanent care with high holding power even after cleaning.

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

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

The C2 to C6 aliphatic diamine 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 entire composition for hair care. When the content of the aliphatic dibasic acid compound of C2 to C4 is less than the above range, the effect of enhancing the hair binding force is insufficient. On the contrary, when the content exceeds the above range, the increase in the effect of the aliphatic dibasic acid compound is insignificant, .

EXPERIMENTAL EXAMPLE 1 Evaluation of hair in a leave-on state

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

The hair was washed with a basic shampoo having no conditioning function and washed with a tress (manufactured by Phoenix Korea), rinsed for 1 minute, and dried for 2 minutes. Then, 0.3 g of the hair care composition of the above- Respectively.

1) Tensile strength

The tensile strength of one hair was measured using a multi-purpose hair conditioner MTT175 (manufactured by DiaStron) using the hair coated with the above Examples and Comparative Examples. The tensile strength refers to the weight of the force applied to the hair until the hair is pulled off. The higher the value, the stronger and healthier the hair. The results obtained at this time are shown in Fig.

2) Surface friction

The surface friction of the hair tress was measured using a multi-purpose hair conditioner MTT 175 (manufactured by DiaStron) using the hair coated with the examples and the comparative examples. The surface frictional force is a value comparing the degree of roughness when passing the surface of the hair, and the smaller the value, the more smooth the hair. The results obtained at this time are shown in Fig.

3) Hair elasticity

The hair tress coated with the above Examples and Comparative Examples was fixed in an arch shape of 1.5 cm in height. It was then pressurized using a push-pull piston with a force increasing by 0.001 N per second starting at 0.001 N. At this time, the force was applied in the vertical direction from the vertex of the arch shape, and the pressure was measured at the same time as pressing the measuring member equipped with the push-pull piston. The force at the point where the arch shape of the hair collapsed was measured and repeated 30 times. At this time, the elasticity of the hair refers to the force that the hair rests upon pressing the center point after bending the hair into the shape of the arch, and the greater the resilience, the greater the elasticity of the hair. The results obtained at this time are shown in Fig.

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

Experimental Example 2. Evaluation of hair after washing
