Description

Hair Styling Shampoo Composition {COMPOSITION OF HAIR STYLING SHAMPOO}

The present invention relates to a hair styling shampoo composition, and more particularly, to a hair styling shampoo composition having a hair-styling retention function and having an excellent hair conditioning effect.

In general, hair cosmetics used to remove contamination of hair and scalp and keep clean and beautiful are used for various purposes such as styling, hair trimming, hair conditioning, damage prevention, dandruff prevention, and hair protection as well as a cleaning function. Recently, researches on multifunctional shampoos that can simultaneously implement such various purposes have been actively conducted. For example, various research attempts and results have been disclosed since the user's convenience can be pursued by performing functions such as rinsing and styling and conditioning at the same time.

There are three ways to create a hair style and keep it fixed for a period of time. Firstly, by chemical change, this is due to a change in the binding position of the hair, generally referred to as 'perm', and can be regarded as a semi-permanent method in that styling is maintained for a fairly long time. Secondly, as a method by physical change, it causes a temporary style change and maintenance effect, and can be easily removed by water or shampoo. This temporary hair style change is generally accomplished by applying a styling product to the hair after using the shampoo. Products used to provide style retention are commercially available in the form of gels, mousses or sprays made from resins or gums. However, such a conventional temporary hair styling product has to be applied separately after the user performs a shampoo for washing, and after applying the styling product to the hair because the hand is used directly when applying the styling product to the hair. In addition, the inconvenience of having to wash hands again is pointed out as a disadvantage. In addition, after using the conventional temporary styling products, there is a disadvantage that the hair becomes stiff and hard. Third, the method of providing a styling polymer to the shampoo composition and providing a hair styling function at the same time has been proposed in various forms in that it has eliminated the inconveniences described above, but due to the characteristics of the styling polymer It has been pointed out that when the hair becomes too stiff or a polymer composed of a water-soluble monomer is used, the styling effect is significantly reduced because the polymer is hardly adsorbed to the hair by washing.

Therefore, the technical problem to be solved by the present invention is to improve the conditioning effect while giving a styling function to the shampoo, to provide a hair styling shampoo composition that can achieve such a technical problem.

The present invention is a terpolymer consisting of a vinylpyrrolidone monomer unit, dimethylaminopropyl methacrylamide monomer unit and lauryl-dimethylpropyl methacrylamidoammonium monomer unit to achieve the above technical problem; And a copolymer consisting of a vinylpyrrolidone monomer unit and a quaternized vinylimidazole monomer unit. Provides a hair styling shampoo composition comprising at the same time.

In the hair styling shampoo composition according to the present invention, the terpolymer includes 60 to 90 wt% of vinylpyrrolidone monomer units, 5 to 30 wt% of dimethylaminopropylmethacrylamide monomer units and lauryl-dimethylpropylmethacrylamido It is preferable to use those consisting of a composition of 1 to 30% by weight of ammonium monomer unit, and as a copolymer, a composition of 50 to 80% by weight of vinylpyrrolidone monomer unit and 50 to 20% by weight of quaternized vinylimidazole monomer unit It is preferable to use those consisting of.

In addition, in the hair styling shampoo composition according to the present invention, the terpolymer and the copolymer are preferably added in a ratio of 95: 5 to 50: 5% by weight.

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

Terpolymers consisting of lauryl-dimethylpropylmethacrylamidoammonium monomer units, vinyl pyrrolidone monomer units and dimethylaminopropylmethacrylamide monomer units disclosed in U.S. Pat. After the polymer film is formed, it is known that the film formed on the surface of the hair is not sticky because the humidity and water resistance of the outside air is not sticky and the hair does not clump and has a smooth characteristic. However, these terpolymers have limitations in providing good styling effects.

In addition, copolymers composed of the vinylpyrrolidone monomer units and vinylimidazole monomer units disclosed in US Pat. No. 6297203 are known to have excellent styling effects. However, such copolymers have a limitation in the amount of the styling polymer adsorbed in relation to the water solubility of the styling polymer, and the hair is sticky in a humid state even after drying after hair washing, so that the hair is not bundled or smooth.

The inventors have described a terpolymer, a vinylpyrrolidone monomer unit and a quaternized vinylimidazole monomer comprising a vinylpyrrolidone monomer unit, a dimethylaminopropylmethacrylamide monomer unit and a lauryl-dimethylpropylmethacrylamidoammonium monomer unit. It was found that the hair styling composition containing a copolymer composed of the unit at the same time has a very good styling effect, and even in a humid condition, the hair becomes sticky or the hair does not clump and smoothes, thereby providing an excellent conditioning effect.

The monomer unit may have a composition of 50 to 20% by weight, and its molecular weight is preferably 80,000 to 1,000,000 and has a cationic charge density of 0.5 to 3.5 meq / g.

The terpolymer and the copolymer are preferably added in a mixture of 95: 5 to 50: 5% by weight in consideration of stickiness, agglomeration, and the like of the hair.

The total content of the terpolymer and copolymer contained in the hair styling composition of the present invention is preferably 0.1 to 10% by weight based on the total weight of the composition. When the content is more than 10% by weight, the viscosity of the shampoo may increase to increase the hair sticking phenomenon, and when less than 0.1% by weight, the action of the styling polymer may be insignificant.

On the other hand, in the present invention, for the formulation of the shampoo, a surfactant generally used in the shampoo composition, such as an anionic surfactant or a non-ionic surfactant may be used alone or in combination, such a surfactant is 5 to 50 relative to the total amount of the shampoo It is preferable to use in the range of weight%. Examples of the anionic surfactant include sodium lauryl sulfate, lauryl ammonium sulfate, magnesium lauryl sulfate, lauryl triethanolamine, sodium polyoxyethylene lauryl sulfate, and polyoxyethylene lauryl sulfate, and the like. Examples thereof include lauryl dimethyl amine oxide and palm oil alkyl dimethyl amine oxide.

As can be seen through Tables 4 and 5, Comparative Example 1, polyquaternium-55 using only Polyquaternium-55 and Polyquaternium-16 alone, polyquaternium-55 alone Compared to Comparative Example 3 using only nium-16 alone, in the case of Examples 1 to 5 using a suitable composition of polyquaternium-55 and polyquaternium-16 according to the present invention, the conditioning effect and the combing force reduction rate were relatively It can be seen that it appeared very well. In addition, in the case of Example 2, which uses the most amount of polyquaternium-55 and polyquaternium-16, the conditioning effect and the combing force reduction rate are smaller than in the case of Example 1, in which the content is relatively low. It can also be seen. If the content of the styling polymer is included above a certain limit, the sticking effect of the styling polymer may have a conflicting effect with the conditioning effect. Therefore, it is also known that special attention is required for the use of an appropriate amount for the styling polymer. have.

When the hair styling shampoo composition using a styling polymer composed of a terpolymer and a copolymer according to the present invention is mixed and used in an appropriate amount, the cleaning effect is naturally achieved, and the function of maintaining the hair style while eliminating the hassle of use is achieved. At the same time, there is an advantage that can solve the conventional problems such as stiff hair even after use at the same time.
