Description

[0001] The present invention relates to a hair cleansing composition having improved conditioning effect,

The present invention relates to a hair cleansing composition with improved conditioning effect, which comprises an anionic surfactant, a cationic vinyl copolymer and a phosphate surfactant.

In recent years, hair is damaged due to various physical and chemical factors such as frequent combing, perming, dyeing, etc., so that hair becomes rough and loses its gloss and softness and softening effect are frequently deteriorated. As a result, the hair is hard to be trimmed, the hair is cut off, and the ends are cracked.

To address this problem, there has been a continuing research into detergents or hair conditioning ingredients to improve the softness of the hair during or after cleaning, and to restore damaged hair. In particular, in order to protect hair, prevent damage, and provide a conditioning effect, a shampoo containing an anionic surfactant as a main component for removing contamination of hair and scalp by merely emphasizing only the cleaning function in the prior art, So-called conditioner shampoos, in which a conditioning agent is added in addition to a surfactant, have been developed and put into practical use, and their use is increasing.

In recent years, U.S. Patent Nos. 5,104,646 and 6,930,078 have attempted to improve the conditioning effect by increasing the adsorptivity of hair conditioning components such as silicone to hair using a coacervate produced by anionic surfactant and cationic polymer. However, they have a disadvantage in that the generation of coacervate by the simple combination of the anionic detergent and the cationic polymer imparts a conditioning effect, so that the amount of produced coacervate is not so small and thus the conditioning effect is weak.

Accordingly, the present invention provides a hair cleansing composition having a high amount of production of a coreacreate and excellent feeling in use after cleansing, after cleansing, and after drying.

In order to achieve the above object, the present invention provides a hair cleansing composition comprising an anionic surfactant, a cationic vinyl copolymer and a phosphate surfactant.

The hair cleansing composition according to embodiments of the present invention includes an anionic surfactant, a cationic vinyl copolymer, and a phosphate surfactant. The composition is characterized in that, in use, 0.5 to 4 volumes of coacervate per volume of the composition are formed on a 10 volume dilution basis.

When the hair cleansing composition of the present invention is diluted with water for use, a large amount of coacervate is produced, and when applied to the hair, the conditioning effect can be increased. Coacervate is a liquid droplet-like inanimate object in which a plurality of organic materials are gathered. When organic matter is present in a colloidal particle state with water molecules attached to each other, a coherent layer is formed. The inventors of the present invention have observed that when the hair cleansing composition of the present invention is diluted in water for use, a large amount of coacervate is produced and the conditioning effect of the hair is excellent when it is used, thereby completing the present invention.

When 1 volume of the hair cleanser composition is diluted to 10 volumes, when the amount of the produced coacervate is less than 0.5 volume based on 1 volume of the hair cleansing composition used for dilution, sufficient conditioning effect of the hair is difficult to be exhibited. It is disadvantageous in that it is not well formed or excessively adsorbed on the hair and hinders the conditioning feeling after use. Thus, it is preferred that the composition, when used, has a volume of 0.5 to 4 volumes of coacervate per volume of the composition used, on a 10 volume dilution basis.

The anionic surfactant is contained as a cleaning component in the hair cleansing composition and is preferably 1 to 45% by weight, 1 to 30% by weight, or 5 to 20% by weight, or 10 to 15% by weight, %. ≪ / RTI > When the content of the anionic surfactant is less than the above range, the cleaning function of the hair cleansing composition is not exhibited properly. If the content exceeds the above range, the cleansing power may be excessively applied to give a rough feeling to the hair.

The anionic surfactant can be used without limitation of the constitution as long as it is included in a composition for ordinary hair cleansing. Examples of the anionic surfactant include sodium lauryl sulfate, ammonium lauryl sulfate, magnesium lauryl sulfate, triethanolamine laurylsulfate, Sodium lauryl sulfate, ammonium polyoxyethylene lauryl sulfate, polyoxyethylene lauryl sulfate triethanolamine sodium polyoxyethylene laurate, ammonium polyoxyethylene laurate, sodium cocoyl taurate, sodium cocoyl glutamate, sodium cocoyl alanate And the like can be used. Preferably, the anionic surfactant may be sodium lauryl sulfate, sodium polyoxyethylene lauryl sulfate, or a mixture thereof.

The cationic vinyl copolymer may be selected from any cationic vinyl copolymer capable of producing coacervate by causing a phosphate surfactant and coacervation. Preferable examples of the cationic vinyl copolymer include a homopolymer, a copolymer, or a mixture of the homopolymer and the copolymer containing at least one selected from the group consisting of compounds represented by the following formulas (1) to (3) .

The cationic vinyl copolymer may more preferably contain the monomer unit represented by the formula (1) in an amount of 25 to 45 mol%. When the monomer unit represented by the general formula (1) is within the above range in the cationic vinyl copolymer, the production of the coreacreate is favorable when the composition is used, and the conditioning effect is excellent even during use and after use.

In addition, the cationic vinyl copolymer may have an average molecular weight in the range of 10,000 to 2,000,000. Considering that it is used as a hair cleansing composition, those having an average molecular weight within the above range are easy to handle and manufacture, and have excellent conditioning effect.

On the other hand, the phosphate-based surfactant can be selected without limiting the constitution as long as it can cause cationic vinyl copolymer and coacervation. Preferably, the phosphate surfactant may be at least one selected from the group consisting of compounds represented by the following formulas (4) to (9).

In this formula,

A ₁ is a straight-chain alkyl group having 8 to 30 carbon atoms or an alkenyl group having 8 to 30 carbon atoms; X is a hydrogen atom or Na.

The phosphate type surfactants represented by the above Chemical Formulas 4 to 9 cause a coacervation with the cationic vinyl copolymer to generate a larger amount of coacervate, and thus the conditioning effect of the hair is excellent even at the time of using and after use of the hair cleansing composition .

On the other hand, the cationic vinyl copolymer may be contained in an amount of 0.01 to 10% by weight, preferably 0.1 to 5% by weight, based on the entire content of the hair cleansing composition. When the content of the cationic vinyl copolymer is less than 0.01% by weight, the production of coacervate is poor and the adsorption of the conditioning component is poor, and the conditioning effect is not sufficiently exhibited. When the content exceeds 10% by weight, And excessively adsorbed on the scalp, reducing the feeling.

The phosphate surfactant contained in the hair cleansing composition has a good foaming property and facilitates the formation of a cationic vinyl copolymer and a coacervate so that the components effective for conditioning are more effectively delivered to the hair to increase the adsorption amount, Excellent wet feeling even when wet. In this case, the phosphate surfactant may be contained in the total hair cleansing composition in an amount of 0.1 to 20% by weight, preferably 1 to 10% by weight. If the content of the phosphate surfactant is less than 0.1% by weight, the effect of forming a coacervate is insufficient. If the content of the phosphate surfactant is more than 20% by weight, physical properties such as viscosity and bubble strength can not be maintained.

On the other hand, according to another embodiment, the hair cleansing composition of the present invention may further include any one or more selected from the group consisting of a cationic polymer, an amphoteric surfactant, a nonionic surfactant, a silicone compound, have.

At this time, the cationic polymer can be selected without limitation in the constitution as long as it can be usually used in a hair washing composition. Preferred examples thereof include cationic guar, such as guar hydroxypropyl trimonium chloride and hydroxypropyl guar hydroxypropyl trimonium chloride, cellulose (polyquaternium-10, polyquaternium-67), dimethylallylammonium chloride polymer, acrylamide -Dimethyldiallylammonium chloride copolymer, polyvinylpyrrolidone (PVP) -dimethylaminoethyl methacrylate copolymer, acrylic acid-dimethyldiallylammonium chloride copolymer, acrylamide-dimethylaminoethyl methacrylate methyl chloride copolymer , And trimethylaminoethyl methacrylate polymer. The cationic polymer may be contained in an amount of 0.001 to 5.0% by weight, preferably 0.1 to 3.0% by weight based on the total weight of the composition, but is not limited thereto.

In addition, the amphoteric surfactant that can be included in the hair cleansing composition functions to enhance the bubble texture by helping to produce the coacervate and making the bubble creamy to an appropriate degree. The amphoteric surfactant that can be used at this time is not particularly limited as long as it can be used in a conventional hair cleansing composition, and the content of the amphoteric surfactant is preferably 1 to 30% by weight based on the total weight of the composition. If the content is less than 1% by weight, it is not sufficient to form a coacervate and can not exert a creamy bubble forming function. If the content is more than 30% by weight, the feeling of use may be reduced due to excessive formation of coacervate and excessively creamy bubbles .

Amphoteric surfactants that can be preferably used include, but are not limited to, coco betaine, lauryl betaine, cocamidopropyl betaine, laamidopropyl betaine, disodium cocoamphodiacetate, sodium cocoamphoacetate, disodium lauroam And may be at least one selected from the group consisting of podiacetate, sodium lauroamphoacetate, coco sulphate, lauryl sulphate, coco hydroxide root, and lauryl hydroxide root. More preferably, cocamidopropyl betaine, disodium cocoamphodiacetate or mixtures thereof may be used.

The nonionic surfactant may be selected without limitation as long as it is included in the hair cleansing composition. Preferably, the nonionic surfactant is selected from the group consisting of diethanolamide laurylate, diethanolamide palm oil fatty acid, and coco fatty acid monoethanolamide One or more selected from the group can be used. The nonionic surfactant may be contained in an amount of 0.01 to 15.0% by weight, preferably 1.0 to 10.0% by weight based on the total weight of the composition, but is not limited thereto.

In order to improve the conditioning effect, the composition for hair cleansing according to the above embodiments may contain at least one conditioning agent selected from silicone compounds and oily oils, And is not particularly limited. Preferably, at least one selected from the group consisting of water insoluble nonvolatile dimethicone, cyclomethicone, aminated silicone, trimethylsilylamodimethicone, vinyl silicone, and derivatives thereof can be used.

The hydrocarbon oil may be at least one selected from the group consisting of liquid paraffin (mineral oil), isoparaffin, and hydrogenated polydecene. The ester oil may be at least one selected from the group consisting of isopropyl myristate, isopropyl palmitate, which can be at least one selected from isostearyl isostearic acid, and ₁₂ C _-15 the group consisting of alkyl benzoate.

The conditioning agent may be included in an amount of 0.01 to 10% by weight, preferably 0.1 to 5.0% by weight based on the total weight of the composition, but is not limited thereto.

[ Experimental Example ] Examples In Comparative Example  Evaluation of efficacy after use of composition for hair cleansing

1. For dry hair Friction force  Measure

After the hair cleansing compositions prepared according to Examples 1 to 4 and Comparative Examples 1 and 2 were treated with hair, the frictional force of the hair was measured by performing the following process. If the hair is damaged, the surface of the hair becomes rough because the cuticle is cracked or excited. Therefore, measuring the surface of the hair can predict the change in the physical state of the surface.

Three hair tresses were prepared for each sample, treated with the composition for hair cleansing of Examples 1 to 4 and Comparative Examples 1 and 2, the water was removed with a towel in a wet state, Then, the physical state change of the surface of the hair was measured using a friction force meter (① Miniature Tensile Tester MTT600: Dia-Stron Ltd., ② RheoWin Software Rev 3.3a: Dia-Stron Ltd., and ③ Extension Speed: 100 mm / min) Respectively. The measurement results are shown in Table 2 below. The larger the rate of reduction of the frictional force of the hair, the greater the degree of smoothness of the surface of the hair.

Classification of experiments Example Comparative Example One 2 3 4 One 2 Decrease (%) 19.5 18.3 22.3 30.5 10.5 11.6

As a result of the test, as shown in Table 2, the hair cleansing compositions of Examples 1 to 4 were found to have smoothness of the surface of the hair when dried compared to the compositions of Comparative Examples 1 and 2. This is because the N-methacryloyloxyethyl-N, N, N-trimethylammonium chloride / N, N-dimethylacrylamide copolymer of Formula 10 prepared in Example 1 and the phosphate of Formulas 4 to 9 of the present invention It is found that the physical state of the hair during drying is considerably better than the case where the surfactant is applied.

2. Measuring and comparing the ease of combing in wet condition

In order to measure the combability of the hair cleansing compositions prepared according to the above Examples and Comparative Examples, the following experiment was conducted. Combing is a cosmetic treatment repeatedly performed in everyday life, and acts to accumulate hair damage. Therefore, the combing force was measured when the hair was shampooed and then wetted, and the ease of combing was measured. Reducing combing force means easier combing when wet.

The hair trays were treated with the compositions of Examples 1 to 4 and Comparative Examples 1 and 2, rinsed, and water was continuously flown in a state in which no air bubbles were generated, and a combing force meter (① Dynamic Combing Tester, ② Loadcell L A & D Max Force 600gf, and ③ Combing Speed: 2000mm / min). The results are shown in Table 3 below. In Table 3, the larger the reduction rate of the force required for combing, the smoother the hair surface and the (-) value means that the friction of the surface is increased before the treatment, which means that the damage of the hair surface is increased.

Classification of experiments Example Comparative Example One 2 3 4 One 2 Decrease (%) 15.5 13.3 16.5 24.7 8.8 9.3

As a result of the experiment, as shown in Table 3, it was confirmed that the hair cleansing compositions of Examples 1 to 4 had a greater reduction rate of the force required for combing as compared with the hair cleansing compositions of Comparative Examples 1 and 2 as a whole there was. This is true when the N-methacryloyloxyethyl-N, N, N-trimethylammonium chloride / N, N-dimethylacrylamide copolymer of Formula 10 and the phosphate surfactants of Formulas 4 to 9 are applied It can be confirmed that the effect of preventing hair damage is the best when wetted.

3. Sensory Evaluation of Hair Conditioning Effect

Eighty women who were highly experienced in sensory evaluation of hair products were evaluated for hair texture after using shampoo prepared in Examples 1 to 4 and Comparative Examples 1 and 2, respectively, by using 10 kinds of usual hair cleansing composition (shampoo) Respectively. The rating scale was given as 1 point for very bad hair texture, 2 points for bad hair texture, 3 points for normal hair texture, 4 points for good hair texture and 5 points for very good hair texture, The results are shown in Table 4 below.

As shown in Table 4, the N-methacryloyloxyethyl-N, N, N-trimethylammonium chloride / N, N-dimethylacrylamide copolymer of Formula 10 was dissolved in a phosphate- When used together with a surfactant, it can be confirmed that both the sensation during rinsing and the feeling after drying are improved at the same time.

4. Coaseurate  Evaluation of yield

Experiments were carried out in the following manner in order to measure the amount of produced coacervate in the hair cleansing compositions prepared according to the above Examples and Comparative Examples.

10 ml of each of the compositions of Examples 1 to 4 and the compositions of Comparative Examples 1 to 2 was diluted with water to prepare 100 ml of a diluted solution. These were prepared in a test tube having a diameter of 2.2 cm and a length of 32 cm and then subjected to sedimentation centrifugation (3,000 rpm, 5 minutes), and the amount of the produced coacervate was measured by volume. The coreacebate is visually identifiable as a liquid viscous liquid form of translucent or opaque white, as shown in Fig. The amount of each produced is shown in Table 5 below.
