Description

샴푸 Shampoo composition for blocking UV}

The present invention relates to a UV blocking function-containing shampoo composition in which the amount of coacervate produced by the anionic detergent and the cationic polymer is increased.

In general, the shampoo commonly used to remove the contamination of the hair and scalp to keep clean and beautiful, contains anionic surfactants with excellent cleaning power as a main component. In recent years, hair has been damaged by wind, heat, sunlight, air pollution, etc. and attention has been paid to protecting the hair due to these causes. In particular, as the five-day work week increases outdoor activities, hair is exposed to the sun, which causes hair damage due to physical and chemical changes caused by sunlight exposure.

Therefore, as one of various attempts to solve this problem, various UV-blocking-containing products that are used before or after adding a UV blocker to a shampoo product or shampoo have been studied. However, in the case of cleaning products such as shampoos, the amount of active ingredients adsorbed is extremely small due to the characteristics of the product, which has a limit in its effect and sustainability.

Therefore, in order to solve these problems, there has been a continuous study on the cleaning agent or cosmetics to keep these UV blocking ingredients in the hair and scalp for a long time after cleaning. Recently, U.S. Patent Publication No. 2003/0199403 attempts to increase the adsorption of solid particle components effective for hair and scalp by coacervates produced by anionic surfactants and cationic polymers, and U.S. Patent Publication No. 2004/0146475 The study is conducting studies to increase the formation of coacetate in conditioning shampoos through the appropriate combination of ethoxy and sulfate levels of cationic cellulose polymers and anionic surfactants.

However, since they generate coacetate by a simple combination of an anionic detergent and a cationic polymer, the amount of coacetate produced is limited, and thus it is not easy to increase the adsorption of active ingredients to improve the effect and its sustainability.

Therefore, the technical problem to be achieved by the present invention is to increase the amount of coacervate produced by the shampoo composition containing UV protection function to enhance the hair and / or scalp adsorption effect of the UV blocker or absorbent by these coacervates and to continue to exhibit the effect To provide.

In order to achieve the above technical problem, the present invention is a shampoo composition comprising an anionic surfactant and a cationic polymer,

UV absorbers or blockers; And it provides a UV blocking function-containing shampoo composition comprising a quaternary ammonium cation surfactant represented by the formula (1).

In Formula 1, R is any one selected from the group consisting of a linear alkyl group having 12 to 22 carbon atoms, branched alkyl group, alkenyl group and alkylamide, n is an integer of 0 to 10.

More preferably, the present invention provides a UV blocking function-containing shampoo composition, characterized in that the content of the quaternary ammonium cationic surfactant in the UV blocking function-containing shampoo composition is 0.1 to 10% by weight based on the total weight of the composition.

More preferably, in the UV-blocking-containing shampoo composition, the UV absorber or UV blocker means those commonly named UV absorbers or UV blockers, for example, sodium benzotriazolyl butylphenol sulfonate, Isoamyl paramethoxycinnamate, ethylhexylmethoxycinnamate, polyquaternium-59, octisol and derivatives thereof, wherein at least one selected from the group consisting of or derivatives thereof is used alone or in combination It provides a UV blocking function-containing shampoo composition.

More preferably, the present invention provides a UV blocking function-containing shampoo composition, characterized in that the content of the UV absorber or blocking agent in the UV blocking function-containing shampoo composition is 0.001 to 5% by weight relative to the total weight of the composition.

More preferably, the present invention provides a UV blocking function-containing shampoo composition, characterized in that the content of the cationic polymer in the UV blocking function-containing shampoo composition is 0.01 to 5% by weight relative to the total weight of the composition.

Hereinafter, the UV blocking function-containing shampoo composition of the present invention will be described in more detail.

The shampoo composition according to the present invention includes a cationic surfactant into which a glyceryl group represented by Chemical Formula 1 is introduced as a base for enhancing coacetate formation.

Referring to Chemical Formula 1, the cationic surfactant used in the present invention is a structure of a quaternary ammonium compound, one of substituents of ammonium ions essentially consisting of an alkylamidopropyl group, and the other is a repeating unit with a hydrophilic group. Glyceryl group having 1 to 11 is condensed and repeated structure, the remaining two substituents are composed of a methyl group.

The quaternary ammonium cationic surfactant contains at least one glyceryl group, which is a hydrophilic group, and is soluble in an aqueous solution called a pseudo-nonionic complex surfactant through interaction with an anionic surfactant. Mixed micelles can be formed. Since the pseudo-nonionic complex surfactant improves the problems of high viscosity and precipitation that occur when the cationic polymer and the anionic surfactant are used at the same time, the amount of the cationic polymer can be reduced even in the presence of the anionic surfactant. It can be increased to increase the amount of coacervate formed.

In addition, the quaternary ammonium cationic surfactant of Formula 1 includes an alkylamido group having a relatively hydrophilic property instead of a long chain fatty acid group, so that the mixed micelle formation ability of a pseudo-nonionic complex surfactant is better. In addition, even in the presence of anionic surfactants, the amount of cationic polymer used may be further increased, and as a result, it may have a special function of generating more coacervates, which are complexes of anionic surfactants and cationic polymers.

The quaternary ammonium cationic surfactant is preferably used 0.1 to 10% by weight based on the total weight of the composition. If the content is less than 0.1% by weight, it is difficult to achieve coacervate formation and stability improvement effect by the quaternary ammonium cation surfactant, and when the content is more than 10% by weight, the hair becomes damp and there is a concern about precipitation and phase stability. May not be suitable for use.

The UV blocking function-containing shampoo composition according to the present invention essentially comprises a cationic polymer to produce coacervate. Although coacervate formation is affected by many factors, it is known that it is most affected by the structure of the cationic polymer, in particular the molecular weight and positive charge density (mEq / g) of the cationic polymer.

The cationic polymer is not particularly limited as long as it can be used in a shampoo composition, for example, may be used by selecting one or more from the group consisting of natural cationic polymer, synthetic cationic polymer and mixtures thereof. .

Examples of the natural cationic polymer that can be used in the present invention include cationic guar such as guar hydroxypropyltrimonium chloride and hydroxypropyl guar hydroxypropyltrimonium chloride, cellulose (polyquaternium-10), and the like. One or more may be used, but is not limited thereto.

Synthetic cationic polymers that can be used in the present invention include, for example, dimethyldiallylammonium chloride polymer, acrylamide-dimethyldiallylammonium chloride copolymer, polyvinylpyrrolidone (PVP) -dimethylaminoethylmethacrylate Copolymer, acrylic acid-dimethyldiallylammonium chloride copolymer, acrylamide-dimethylamino ethylmethacrylate methyl chloride copolymer, trimethylaminoethylmethacrylate polymer, and the like may be used, but are not limited thereto.

In the UV blocking function-containing shampoo composition of the present invention, the content of the cationic polymer is preferably 0.01 to 5% by weight based on the total weight of the composition. If the content is less than 0.01% by weight, coacervate is poorly formed, so that the UV blocking or absorbing component is less adsorbed, and the UV blocking effect is not sufficiently exhibited. If the content exceeds 5% by weight, the coacervate is excessively produced. This can be caused by excessive adsorption on the hair and scalp, which can cause a bad shampoo.

In the UV-blocking-containing shampoo composition of the present invention, the molecular weight of the cationic polymer is preferably 200,000 to 3,000,000. If the molecular weight is less than 200,000, the formation of coacetate is poor, and the adsorption of UV blocking or absorbing components is lowered, so that the UV blocking effect is not sufficiently exhibited. If the molecular weight exceeds 3,000,000, the UV blocking component is excessively produced. This can be caused by excessive adsorption on this hair and scalp.

In addition, in the UV blocking function-containing shampoo composition of the present invention, the charge density of the cationic polymer is preferably 0.1 to 1.4 mEq / g. This means that coacervates are less likely to be produced when the charge density of the cationic polymer is less than 0.1 mEq / g, and the resulting coacervates are too solid-gel when the charge density is greater than 1.4 mEq / g. This is because it is difficult to help oily or particulate UV-blocking components adsorb to the hair due to its gel state.

UV absorbers or UV blocking agents that can be used in the UV blocking function-containing shampoo composition according to the present invention means those commonly named UV absorbers or UV blocking agents, for example, sodium benzotriazolyl Butylphenol Sulfonate, Cibafast H Liq., Ciba), Isoamyl p-Methoxycinnamate, Crodasome UV-A / B, Croda, Ethylhexyl Methoxycinnmate, Uvinul MC-80, BASF Polyquaternium-59, Crodasorb UV-HPP, Croda, Octizol, Spectra-Sorb UV-5411, Aemerican Cynamid / Fine Chemical or derivatives thereof are preferably used alone or in combination. Do.

In addition, the content of such a UV absorber or blocking agent is preferably 0.001 to 5% by weight relative to the total weight of the composition. If the content is less than 0.001% by weight, the absolute amount of the UV blocking agent or absorbent is not sufficient, and the UV blocking effect is not sufficiently exhibited. If the content exceeds 5% by weight, these components are excessively adsorbed on the hair and the scalp, which may give a bad feeling. Because it can.

The UV blocking function-containing shampoo composition according to the present invention includes an anionic surfactant as a cleaning component.

The anionic surfactant that can be used in the present invention is not particularly limited as long as it can be used in a conventional shampoo composition, the content of such anionic surfactant is preferably 1 to 50% by weight relative to the total weight of the composition. This is because the content is less than 1% by weight does not exert a cleaning function properly, when the content exceeds 50% by weight is too much cleaning power can give a rough feeling to the hair and scalp.

As the anionic surfactant that can be used in the present invention, for example, sodium lauryl sulfate, ammonium lauryl sulfate, magnesium lauryl sulfate, lauryl triethanolamine, sodium polyoxyethylene lauryl sulfate, polyoxyethylene lauryl sulfate Ammonium and the like may be used one or more, but is not limited thereto.

The UV blocking function-containing shampoo composition of the present invention may further contain nonionic surfactants and / or amphoteric surfactants within the range of not impairing the object of the present invention for the purpose of increasing cleaning power and the like.

As the nonionic surfactant that may be used in the present invention, for example, lauryl acid diethanolamide, palm oil fatty acid diethanolamide, palm oil fatty acid monoethanolamide, and the like may be used, but are not limited thereto.

As the amphoteric surfactant that can be used in the present invention, for example, betaine, amido propyl betaine, coco amppocarboxy glycinate, sacosinate, and the like may be used, but are not limited thereto. .

In addition, the UV-blocking function-containing shampoo composition of the present invention may further include a silicone compound for the purpose of imparting a conditioning effect, improving the physical properties of the shampoo, improving the feeling, etc. within the range that does not impair the object of the present invention. Such silicone compounds are not particularly limited as long as they can be used in a shampoo composition, for example, water insoluble non-volatile dimethicone, cyclomethicone, aminated silicon, trimethylsilyl amodimethicone, vinyl silicone, etc. One or more components or derivatives thereof collectively referred to as silicone may be used.

When the silicone compound is added to the UV blocking function-containing shampoo composition of the present invention, the content of the silicone compound is preferably 0.1 to 5% by weight based on the total weight of the composition, more preferably 0.5 to 3% by weight. This is because when the content is less than 0.1% by weight, a sufficient conditioning effect is not exerted, and when it is more than 5% by weight, there may be a problem in formulation formation.

In addition, the UV blocking function-containing shampoo composition of the present invention may contain an oil-based component for the purpose of improving the physical properties of the shampoo, improving the feeling, etc. within the range that does not impair the object of the present invention. Hydrocarbon oil, synthetic ester oil, etc. may be used as the oil-based oil component, and liquid paraffin (mineral oil), isoparaffin, hydrogenated polydecene, etc. may be used as the hydrocarbon oil, and ester oil may be used in advance. sustaining the acid may be used a small profile, such as isopropyl palmitate, isopropyl stearate, isostearyl, _-15 C ₁₂ alkyl benzoate.

In addition, the UV blocking function-containing shampoo composition according to the present invention may further contain additives such as preservatives, thickeners, viscosity regulators, pH adjusters, fragrances, dyes, conditioning agents that can be used as a component of the shampoo composition in general These can be easily purchased and used commercially. Examples of the preservative include methyl paraoxybenzoate, methylchloroisothiazolinone and a mixture of methylisothiazolinone (trade name: Kathon CG, manufactured by Rohm & Haas, USA). Examples of the thickener and the viscosity modifier include hydroxypropyl methyl cellulose, hydroxymethyl cellulose, sodium chloride, ammonium chloride, propylene glycol, hexylene glycol, and the like. Citric acid, sodium hydroxide, triethanolamine, etc. are mentioned as a pH adjuster. Examples of the dyes include water-soluble tar pigments. Conditioning agents include animal and vegetable extracts, proteins and protein variants, and Fatty Acid.

Hereinafter, the present invention will be described in detail with reference to Examples. However, embodiments according to the present invention can be modified in many different forms, the scope of the present invention should not be construed as limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

<Evaluation of coacervate production amount>

To determine the amount of coacervate that enhances hair and scalp adsorption of UV absorbers or blocker components, the concentration using the actual detergent was determined to be 10% by weight of detergent, and 10 g of sample was measured to determine the amount of coacervate at this concentration. The coacervate produced by dilution at 90 g was centrifuged to discard the supernatant and the precipitated portion was taken to determine the amount of coacervate produced. In some cases, when the coacervate production concentration is 10% or less, since it is easy to be washed off when rinsing using an actual detergent, the present invention is based on 10 wt% of the detergent. The results are shown in Table 2 below.

Example Comparative example One 2 3 4 5 6 7 8 One 2 3 4 Production amount (mg) 47 50 68 70 73 74 90 88 32 35 40 44

As shown in Table 2, when comparing the production amount of Examples 1 to 4 and Comparative Examples 1 to 4 each containing 0.5% by weight of the quaternary ammonium cation surfactant of Formula 2 to the total weight of the detergent composition, according to the present invention It can be seen that the compositions of Examples 1-4 containing quaternary ammonium cationic surfactants formed more coacervates. Similarly, the production amounts of Examples 5 to 8 and Comparative Examples 1 to 4, each containing 2% by weight of a quaternary ammonium cationic surfactant of Formula 2, were compared to those containing quaternary ammonium cationic surfactants according to the present invention. It can be seen that the compositions of Examples 5-8 formed more coacervates, and that the compositions of Examples 5-8, which contained more quaternary ammonium cation surfactants, had a relatively small amount of quaternary ammonium cation. It was found that a greater amount of coacervate was formed than the compositions of Examples 1-4 containing surfactant.

Evaluation of Friction Force Measurement on Hair

After treating the compositions of Examples 1-8 and Comparative Examples 1-4 to the hair, the frictional force of the hair was measured. When the hair is exposed to the sun, the hair is roughened by UV damage, which causes the cuticle to crack or excite. 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, then the shampoo composition was treated, dried and exposed to the sun for about 5 hours. Each hair tress was repeated 10 times in the same manner as above. The degree of damage to the hair is measured by using a friction force tester (① Miniature Tensile Tester MTT600: Dia-Stron Ltd., ② RheoWin Software Rev 3.3a: Dia-Stron Ltd., ③ Extension Speed: 100mm / min). State change was measured. The results are shown in Table 3 below.

Thus, after the shampoo treatment to the hair was measured by combing force, the hair damage prevention effect was measured. The reduced combing force means that there is an effect of preventing hair damage.

The compositions of Examples 1-8 and Comparative Examples 1-4 were each treated in a hair tray, dried in dry and exposed to the sun for about 5 hours. Each hair tress was repeated 10 times in the same manner as above. Hair damage was measured using a combing force gauge (① Dynamic Combing Tester, ② Loadcell L A & D Max Force 600gf and ③ Combing Speed: 2000mm / min). The results are shown in Table 4 below.
