Description

[0001] Hair conditioning composition [0002]

The present invention relates to a hair conditioning composition.

In general, hair dyeing agents for dyeing keratin fibers are classified into temporary hair dyeing agents, permanent hair dyeing agents and permanent hair dyeing agents depending on the duration of hair dyeing effect, and the dyeing principle of each hair dyeing agent is very different.

The temporary hair dye uses a tar pigment and stains the hair by adsorbing nonionic, cationic and / or anionic dyes on the surface of the hair and exhibits a temporary dyeing effect because the dye is thoroughly cleaned by rinsing the hair with 1-2 shampoo . Permanent hair dyeing agents are also called oxidative condensation type hair dyeing agents and generally consist of a first agent containing a dye precursor and an alkalizing agent typified by an aromatic amino compound such as paraphenylenediamine and a second agent containing hydrogen peroxide as an oxidizing agent . In the case of such an oxidative condensation type hair dye, when the mixed solution of the first and second agents is applied to the actual hair, the dye precursor is penetrated into the hair, and the dye precursor is oxidized and condensed in the hair by the oxidizing agent to synthesize the dye The principle of color development is used. Condensation polymerization of dye molecules in the hair forms a high molecular weight dye, and because of its molecular size, it is trapped inside the hair, which leads to high salt strength and good color persistence. The semi-permanent hair dye has the same coloring principle as the permanent hair dye but adjusts the type and content of the alkaline agent and the oxidizer so that the hair dye is less persistent than the permanent hair dye but the hair damage is reduced.

However, the dyes or dye precursors used in the currently marketed temporary hair dyeing agents, semi-permanent hair dyeing agents and permanent hair dyeing agents have water-soluble properties. Therefore, the color is discolored or discolored because the dye is dissolved in the water and eluted out of the hair by washing such as shampoo.

However, the hair dye that expresses color by oxidation and condensation has a characteristic that the molecular size of the dye produced inside the hair increases, and the dye is not released to the outside because it is trapped inside the hair. However, in actuality, physical damage such as desorption of the cuticle layer on the surface of the hair may deteriorate the resistance of the hair to the outside and barrier formation ability of the outflow of the internal material. In addition, the chemical damage caused by the chemical treatment such as the fumigation and decolorization and dyeing destroys the dense protein structure in the hair to destroy the filament structure constituting the hair, induces the inner pupil, Thereby causing the phenomenon that the dye can move. Therefore, discoloration and discoloration of the permanent hair dye are frequently caused by physical and chemical damage.

As a conventional post-treatment technique for sustaining hair dyeing, there is a technique for enhancing the durability of dyeing by utilizing the physiological characteristics of hair or applying a temporary hydrophobic substance to the outside.

Patent Document 1 discloses a shampoo composition having an acidic pH that improves the phenomenon that the dye inside the hair is eluted to the outside by utilizing the phenomenon that the cuticle layer on the outer edge of the hair converges when the pH of the hair is lowered. However, due to the aqueous base and a large amount of anionic surfactant, the shampoo composition can not fundamentally solve the phenomenon that the dye existing inside the hair actually leaks to the outside, and the effect can be expected only during the washing operation of the hair. It is limited.

On the other hand, a silicone derivative is generally used as a means for hydrophobizing the surface of hair, but the resistance due to the cleaning agent is insufficient so that only a temporary effect can be expected.

The present invention relates to a rib-on type non-aqueous hair conditioning composition having an effect of protecting hair damaged by dyeing while having a hair conditioning effect.

In the present invention, the water-insoluble acrylic polymer,

Silicone elastomer,

The cationic polysiloxane and /

There is provided a rib-on type non-aqueous hair conditioner composition comprising a lower alcohol having 6 or less carbon atoms.

The hair conditioning composition according to the present invention has an effect of protecting hair damaged by dyeing while having a hair conditioning effect.

The conditioning composition has a quality of use that adsorbs hydrophobic materials with a sustaining force that are not easily cleaned by hair cleaning on the hair surface and minimizes hair stickiness by the adsorbed ingredients. In addition, it is possible to reduce the phenomenon that the dye inside or outside the hair is eluted or eliminated from the hair by moisture during shampooing, and ultimately, the color of the dyed hair can be sustained.

The present invention relates to a water-insoluble acrylic polymer,

Silicone elastomer,

The cationic polysiloxane and /

On type hair conditioner composition comprising a lower alcohol having 6 or less carbon atoms.

Hereinafter, the rib-on type non-aqueous hair conditioner composition according to the present invention will be described in more detail.

The conditioning composition in the present invention makes the hair more manageable, such as wetting the wetted hair and lowering the static charge during drying and avoiding waving. In addition to the above effects, the present invention can improve dyeing persistence of dyed hair.

Such a conditioning composition is divided into a rinse type which is a type rinsed according to a formulation and a leave-on type which is not rinsed after a formulation. The conditioning composition of the present invention may be a leave-on type composition that is not rinsed after application.

 In addition, the conditioning composition is classified into a water-based composition and a non-aqueous composition, and in the present invention, a non-aqueous hair conditioning composition can be used.

The non-aqueous hair conditioning composition of the rib-on type can be used to further improve dyeing persistence.

The rib-on type non-aqueous hair conditioner composition of the present invention may comprise a water-insoluble acrylic polymer, a silicone elastomer, a cationic polysiloxane and a lower alcohol having 6 or less carbon atoms.

In the present invention, the water-insoluble acrylic polymer can be strongly adsorbed on the hair and imparts hydrophobicity to the hair, thereby preventing the desorption of the dyeing component by washing the shampoo and the like, thereby improving the durability of the dyeing.

The kind of the water-insoluble acrylic polymer is not particularly limited, and it may be a compound having a group capable of imparting hydrophobicity to the acrylic copolymerization polymer. For example, the water-insoluble acrylic polymer may be at least one selected from the group consisting of acrylate / stearyl methacrylate copolymer and polyquaternium-99 (INCI name). Preferably polyquaternium-99, which has both hydrophobic character and cationicity.

The acrylate / stearyl methacrylate copolymer, which is a hydrophobic acrylic polymer, has a monomer structure having an alkyl side chain in the main chain of acrylate, and therefore has a solubility not soluble in water and soluble in alcohol. The hydrophobic properties expressed by the repeated alkyl side chains can be temporarily adsorbed to the hair to hydrophobize the hair. Further, polyquaternium-99 has a repeating unit having a cationic amine group as shown in the following formula (1). The surface of hair damaged by dyeing is exposed to a part of amino acids and has higher chargeability compared to healthy hair. It is possible to bond more strongly than simple adsorption because ionic bonding is possible. Particularly, since polyquaternium-99 has an alkyl group and a cationic repeating unit at the same time, it can impart more permanent hydrophobicity to hair.

Therefore, when the conditioning composition according to the present invention is applied to hair, it is difficult to desorb due to shampoo due to its strong adsorption to hair and its hydrophobic property, so that a certain amount of residue can be left to impart hydrophobicity to hair.

In the following formula 1, N of R ₂ may be an integer of 4 to 22.

[Chemical Formula 1]

The content of the cationic acrylic polymer may be 0.1 to 20.0 wt%, preferably 0.5 to 10.0 wt%, based on the total weight (100 wt%) of the composition. If the content is less than 0.1% by weight, sustained hydrophobicity can not be imparted to the hair surface. If the content is more than 20.0% by weight, stickiness of the hair may be caused and performance as a hair conditioning composition may not be exhibited.

The silicone elastomer in the present invention can be used to alleviate the stickiness of the composition.

The above-mentioned water-insoluble acrylic polymer can form a hydrophobic coating on the hair, but there is a fear that the side chain becomes sticky on the surface of hair due to the inherent characteristics of the polymer as an oil soluble component. The hair tends to clump together due to the tackiness, which adversely affects the sensibility of the composition for conditioning the hair.

In order to solve the above problems, a silicone elastomer may be used in the present invention. The silicone elastomer provides a feeling of non-stick feeling to the hair due to its unique three-dimensional structure and can reduce stickiness which is a disadvantage of the water-insoluble acrylic polymer. Further, in addition to the hydrophobic coating by the water-insoluble acrylic polymer, it is possible to improve the hydrophobicity of the hair and further improve the persistence of the hydrophobic coating on the hair.

The type of the silicone elastomer is not particularly limited and may be a compound having a molecular structure in which a high molecular weight silicone polymer having a main chain of a vinyl group is crosslinked. Examples thereof include dimethicone / vinyl dimethicone cross polymer, dimethicone / Phenyl vinyl dimethicone cross polymer, vinyl dimethicone / lauryl dimethicone cross polymer, and lauryl polydimethylsiloxy ethyl dimethicone / bis-vinyl dimethicone cross polymer, and preferably May be dimethicone / vinyl dimethicone crosspolymer.

The content of the silicone elastomer may be 0.1 to 10.0 wt%, preferably 0.2 to 5.0 wt%, based on the total weight (100 wt%) of the composition. If the content of the silicone elastomer is less than 0.1% by weight, the hair sticky due to the water-insoluble acrylic polymer can not be relieved and sticking to each other. When the content of the silicone elastomer is more than 10.0% by weight, There is a fear that the adsorption of miraculous hair is inhibited and formation of the hydrophobic film of the hair is hindered.

In the present invention, the cationic polysiloxane is a water-insoluble acrylic polymer which is applied to impart hydrophobicity to hair and to enhance persistence of the hydrophobicity, and a phenomenon in which the silicone elastomer applied for improvement of hydrophobicity is independently separated from the hair surface and coated Can be used to reduce.

The cationic group in the structure of the cationic polysiloxane is adsorbed through the ionic bond to the anionically charged site of the hair and the siloxane group of the cationic polysiloxane can form a hydrophobic bond with the alkyl group of the silicone elastomer and the water- have. Thus, the cationic polysiloxane can significantly improve the durability of hair surface hydrophobicity of the conditioning composition of the present invention.

In particular, cationic polysiloxanes with cationic tendency tend to be better adsorbed on damaged hair surfaces than polysiloxanes which do not have a polar group, because the hair is damaged and the surface can ionically bind to the anionically charged moiety.

The kind of the cationic polysiloxane is not particularly limited and may have a structure in which the polymer main chain is composed of a repeating unit of SiO ₂ and the side chain has an amine group having cationic property. For example, amodimethicone, trimethylsiloxia modimethicone, amodimethicone hydroxystearate, amodimicecone / silsesquioxane copolymer, bis (C13-15 alkoxy) hydroxybutamido Amidomethicone, bis (C13-15 alkoxy) fi- azammimethicone, diphenylamodimethicone, and fizi-amodimethicone, and preferably at least one selected from the group consisting of bis (C13- 15 alkoxy) < / RTI >

The content of such a cationic polysiloxane may be from 0.1 to 20% by weight, and preferably from 0.5 to 10.0% by weight, based on the total weight of the composition (100% by weight). When the amount of the cationic polysiloxane is less than 0.1% by weight, the persistence of hair hydrophobicity may be deteriorated. When the amount of the cationic polysiloxane is more than 20.0% by weight, the hydrophobic film formation of the hair due to the competitive reaction of the non- There is a risk of interference.

In the present invention, a lower alcohol having 6 or less carbon atoms can be used as a solvent. The water-insoluble acrylic polymer is low in direct solubility with silicone oil. Thus, lower alcohols having 6 or less carbon atoms as solvents can be used to prepare the conditioning composition.

The kind of the lower alcohol having 6 or less carbon atoms is not particularly limited and may be, for example, at least one selected from the group consisting of ethanol, isopropyl alcohol, n-butyl alcohol and hexyl alcohol, preferably ethanol.

The content of the lower alcohol having 6 or less carbon atoms may be 0.1 to 40% by weight, preferably 1 to 10.0% by weight, based on the total weight of the composition (100% by weight). The solubility of the water-insoluble acrylic polymer in the above content range is excellent.

In the present invention, in addition to the above-described components, components such as silicone derivatives, ester oils, and natural oils may be used as needed. In addition, the composition of the present invention may contain additives for various cosmetics other than the water-soluble components in order to control the hair conditioning effect and the texture of the composition.

According to the embodiment of the present invention, the conditioning composition of the present invention has an excellent dyeing durability and color change prevention effect as compared with the comparative example, and has excellent dyeing sustainability effect .

Experimental Example  1. Hair Color change  Measure

The hair tresses were weighed in a bundle shape by bundling the hair roots with a weight of 1 g, and the hair tress was initialized, and the hair was cleaned to make the surface condition of the hair constant. The rinse was wetted with running water at about 30 ° C for 10 seconds and then washed with SLES 1% aq. The solution was applied to a weight of 1/10 of the weight of the solution, washed by hand for 30 seconds, washed with flowing water at 30 ° C for 30 seconds, dried with a hair dryer for 1 minute, and the above procedure was repeated three times.

The hair tress initialized by the above treatment method was dyed in accordance with the usage and dosage of the hair dye preparation method using a commercially available 2-type oxidative condensation permanent hair dye.

Thereafter, the compositions of Examples and Comparative Examples were applied at a weight ratio of 1/10 by weight to the weight of the dyed hair tress, and after 10 hours of storage, the SLES 15% aq. Solution for 3 minutes and completely dried. This procedure was repeated 5 times in total.

The color difference was quantified by measuring the color change of hair using a spectrophotometer for each treatment process based on the color before processing, and the color deviation, Delta E value, was calculated and compared.

The color of the hair tress immediately after the initial dyeing was used as a control. The color difference between the treated sample and the control group was calculated using the following Equation 1, and the results are shown in Table 2 below.

[Equation 1]

△ E: color difference

L: Bright and dark, the larger the value, the brighter (0 - 100)

a: Green to Red, positive value indicates red color, negative value green color. The larger the absolute value, the stronger the color.

b: Blue to Yellow, a positive value indicates an yellow color, and a negative value indicates a blue color. The larger the absolute value, the stronger the life.

Control group One time processing 2 processing 3 times processing 4 times processing 5 times processing Comparative Example 1 Control 7.2 9.2 11.6 13.3 15.8 Comparative Example 1 Control 2.1 4.2 6.1 6.9 8.4 Comparative Example 3 Control 7.4 9.1 12.0 13.7 15.3 Comparative Example 4 Control 6.9 8.9 11.6 13.6 15.1 Example 1 Control 1.7 4.0 5.5 6.8 7.7 Example 2 Control 1.5 2.9 3.5 4.8 5.7

As shown in the above table, the composition of Comparative Example 1 which does not contain a water-insoluble acrylic polymer, a silicone elastomer and a cationic polysiloxane and ethanol has a relatively large change in ΔE due to repeated washing with an ionic surfactant, As a result, the color of hair was much different from the control group.

In Comparative Example 2, the color persistence was improved by the water-insoluble acrylic polymer. The silicone elastomer of Comparative Example 3 was used, but the change of? E was similar to that of Comparative Example 1, and it can be confirmed that the silicone elastomer alone can not improve the durability of the dye. In Comparative Example 4, a cationic polysiloxane was used, but as in Comparative Example 3, the cationic polysiloxane could not improve the persistence of dyeing.

When the compositions of Examples 1 and 2 were used, it was confirmed that the dyeing color of the hair was remarkably improved by repeated washing even when compared with the comparative example. Examples 1 and 2 are compositions containing water-insoluble acrylic polymer, silicone elastomer, amodimethicone, and ethanol at the same time to improve dyeing persistence upon shampoo cleaning with anionic surfactants as compared with Comparative Examples 1 to 4 . In addition, in comparison between Example 1 and Example 2, it can be confirmed that the effect of improving the dyeing durability of the water-insoluble acrylic polymer due to hydrophobicity of the hair surface is further improved by the addition of the cationic polysiloxane.

Experimental Example  2. Measurement of stickiness of hair

To evaluate the stickiness of the compositions prepared in Examples and Comparative Examples, sticking of the hair through sensory evaluation was carried out by the following experimental process.

The evaluation method was applied to the evaluator's hair by taking 3 g of the composition prepared in the above Examples and Comparative Examples into the hands of the evaluators, and the degree of stickiness of the hair was recorded on a scale of 5 points. And the average value was calculated. The lower the score, the more sticky, and the higher the score, the less sticky.

The results are shown in Table 3 below.

<Criteria for each item>

1 point: very bad

2 points: Poor

3 points: Normal

4 points: Good

5 points: Very good

Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Example 1 Example 2 Stickiness 4.1 2.4 4.3 4.0 4.4 4.2

As shown in the above table, the comparative example 2 in which only the water-insoluble acrylic polymer was applied showed many stickiness on the surface of the hair, while the comparative example 1, the comparative example 3 and the comparative example 4 in which the water- Evaluation results that are not sticky can be confirmed.

In addition, it can be confirmed that the tackiness of Examples 1 and 2, in which the water-insoluble acrylic polymer and the silicone elastomer are simultaneously applied, is reduced as compared with Comparative Example 2. The compositions of the Examples showed no more than equal tackiness compared to Comparative Example 1, a common water-insoluble hair conditioning composition.
