Description

Conditioning shampoo composition

The present invention relates to a conditioning shampoo composition containing a cleaning surfactant, a conditioning agent, a pearling agent and a hydrophilic thickener.

In general, various hair cosmetics are generally used to remove contamination of hair and scalp and keep them clean and beautiful. In particular, the shampoo used for the purpose of removing contaminants contains a cleaning surfactant having excellent cleaning power as a main component.

Recently, hair is damaged by various factors such as physical and chemical and environmental factors such as frequent perm and dyeing, and roughness is increased, and the luster loses softness and softening effect frequently. As a result, the friction force increases, making it difficult to clean the hair by combing and the like, such that the hair is cut off or the tip is cracked.

In order to solve this problem, continuous research on cleaning agents or cosmetics to improve the softness of the hair at the time of cleaning or after cleaning and to restore damaged hair has been continued. In particular, in order to protect hair, prevent damage, and give conditioning effects to shampoos that have conventionally emphasized cleaning functions, so-called conditioning shampoos have been developed and put into practical use in addition to the cleaning surfactant as a main ingredient. Usage is on the rise.

Korean Patent Laid-Open Publication No. 10-0316976 uses a silicone compound such as a water-insoluble nonvolatile dimethicone, cyclomethicone, amino silicone, amodimethicone, trimethylsilyl amodimethicone and derivatives thereof as a hair conditioning component. Doing. However, such a silicon-containing composition has a disadvantage in that it is difficult to keep the insoluble and nonvolatile dispersed silicone in a dispersed state for a long time.

In addition, in the case of using a cationic surfactant as a conditioning agent, there is a disadvantage in that the conditioning effect and the cleaning power are lowered because it forms a precipitate in combination with the anionic surfactant as a cleaning component, and there is a limit in the amount of use thereof.

In order to solve this problem, a pearl composition prepared using a common composition including a pulping agent, a dispersing agent, and a pearl adjuvant and a general cooling method and mixed in a separate product has been used as a shampoo composition (US Pat. No. 5,925,604, US Pat. 6,165,955), there was a disadvantage in that the stability of the product in a small amount of use, the stability of the product is improved in a large amount of use, but due to the rough feeling of the pulping agent, the soft texture is lowered during rinsing, the smooth texture is lost when wet, This had the disadvantage of being rough.

In addition, US Pat. No. 5,955,066 used fatty alcohols, fatty acids, fatty alcohol derivatives and fatty acid derivatives to improve the conditioning effect and stability of the shampoo, but this causes a decrease in the low temperature stability of the shampoo by lowering the viscosity at low temperatures.

Accordingly, the technical problem to be achieved by the present invention is to solve the above problems, to provide a conditioning shampoo composition that is excellent in the conditioning effect and improved in the spreadability and time-lapse stability in use.

In order to achieve the above technical problem, the present invention is a conditioning shampoo composition containing a cleaning surfactant, a conditioning agent, a pearling agent and a hydrophilic thickener, the dialkylaminoalkyl methacrylate represented by the following formula (1) as the hydrophilic thickener It provides a conditioning shampoo composition, characterized in that it contains a polymer.

In Formula 1, R ₁ is hydrogen or an alkyl group, A is any one selected from the group consisting of linear and branched alkyl groups having 1 to 6 carbon atoms and linear and branched hydroxyalkyl groups having 1 to 4 carbon atoms, R ₂ , R ₃ and R ₄ are each independently selected from the group consisting of alkyl groups and benzyl groups having 1 to 18 carbon atoms, and X is any one selected from the group consisting of halogen group elements, sulfate groups and acetate groups.

The present invention uses a hydrophilic thickener of Formula 1 in a shampoo composition having a conventional pearly feeling including a cleaning surfactant, a conditioning agent and a pulping agent, and a feeling of stability that occurs when a small amount of the conventional pulping agent is used and a feeling that occurs when a large amount is used. It is based on the surprising fact that it is possible to provide a conditioning shampoo composition that improves the deterioration of the conditioning effect, thereby increasing stability over time and improving the conditioning effect.

Hereinafter, the present invention will be described in detail.

The shampoo composition according to the present invention contains a cleaning surfactant as a cleaning component. The cleaning 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, for example, at least one from the group consisting of an anionic surfactant, a nonionic surfactant and an amphoteric surfactant. Can be selected.

The content of the cleaning surfactant is preferably 1 to 50% by weight based on the total weight of the composition. This is because the content of less than 1% by weight does not properly exert a cleaning function, when the content exceeds 50% by weight is excessive cleaning power gives a rough feeling to the hair.

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 One or more may be used, but is not limited thereto.

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. .

The shampoo composition according to the present invention contains a conditioning agent in order to enhance the conditioning effect, and preferably contains one or more conditioning agents selected from the group consisting of cationic polymers, silicone compounds or mixtures thereof.

The cationic polymer is not particularly limited as long as it can be generally used in the shampoo composition, for example, may be used one or more from the group consisting of natural cationic polymer, synthetic cationic polymer and mixtures thereof. As the natural cationic polymer that can be used in the shampoo composition of the present invention, for example, cationic guar such as guar hydroxypropyltrimonium chloride, hydroxypropyl guar hydroxypropyltrimonium chloride, cellulose (polyquaternium-10) ) May be used one or more, but is not limited thereto. Synthetic cationic polymers that may also be used in the shampoo composition of the present invention include, for example, dimethyldiallylammonium chloride polymer, acrylamide-dimethyldiallylammonium chloride copolymer, polyvinylpyrrolidone (PVP) -dimethyl One or more aminoethyl methacrylate copolymers, acrylic acid-dimethyldiallylammonium chloride copolymers, acrylamide-dimethylamino ethylmethacrylate methyl chloride copolymers, trimethylaminoethylmethacrylate polymers, etc. may be used. It doesn't happen.

In 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. This is because when the content is less than 0.01% by weight, the conditioning effect may be weak, and when it exceeds 5% by weight, the cationic polymer is excessively adsorbed on the hair and the scalp to give a damp feeling.

It is preferable that the conditioning shampoo composition of this invention contains a silicone compound as said conditioning agent. The silicone compound is not particularly limited as long as it can be commonly used in shampoo compositions, for example, water-insoluble nonvolatile dimethicone, cyclomethicone, aminated silicon, amodimethicone, trimethylsilylamodimethicone, and the like. One or more components commonly referred to as silicones and derivatives thereof can be used.

In the present invention, the content of the silicone compound is preferably 0.1 to 5% by weight, more preferably 0.5 to 3% by weight based on the total weight of the composition. This is because if the content is less than 0.1% by weight, the conditioning effect may be weak, and if it is more than 5% by weight, there may be a problem in the formulation formation.

The shampoo composition according to the present invention contains a pearling agent. These pulsing agents are used to impart a brilliant pearl metallic luster to the appearance of the shampoo to improve the appearance and to maintain the dispersed water-insoluble shampoo component in the product for a long time stable.

In the present invention, the content of the pulping agent is preferably 0.1 to 5% by weight, more preferably 1 to 3% by weight based on the total weight of the composition. This is because when the content is less than 0.1% by weight, there is not enough pearly feeling, and when the content is more than 5% by weight, the hair feels dry even after being very rough and dry during rinsing.

The pulping agent is not particularly limited as long as it can be commonly used in the shampoo composition, for example, ethylene glycol monoester, ethylene glycol diester, propylene glycol and oligomeric alkylene glycol and the like selected from the group consisting of Can be. The pulping agent, which is solid at room temperature, is melted and then mixed with an anionic or nonionic surfactant to be added to the shampoo composition in a liquid state, or melted and then added to the shampoo composition in a crystalline state obtained through a conventional cooling crystallization method. Can be.

The shampoo composition according to the present invention contains a dialkylaminoalkyl methacrylate polymer represented by the following general formula (1) as a hydrophilic thickener.

<Formula 1>

In Formula 1, R ₁ is hydrogen or an alkyl group, A is any one selected from the group consisting of linear and branched alkyl groups having 1 to 6 carbon atoms and linear and branched hydroxyalkyl groups having 1 to 4 carbon atoms, R ₂ , R ₃ and R ₄ are each independently selected from the group consisting of alkyl groups and benzyl groups having 1 to 18 carbon atoms, and X is any one selected from the group consisting of halogen group elements, sulfate groups and acetate groups.

Since the dialkylaminoalkylmethacrylate polymer is present in the form of micro sized swollen particles in an aqueous solution, the viscosity is increased in the shampoo composition and the dispersed particles prevent the coalescence and / or rise (float) of the water-insoluble components. It is believed that the components are evenly dispersed in the shampoo composition to ensure long term stability.

In particular, when the silicone compound described above is used as a conditioning agent in a shampoo composition, it is difficult to store for a long period of time. The dialkylaminoalkylmethacrylate polymer, which is a hydrophilic thickening agent of the present invention, has a breakage state in which the dispersed state of silicone particles, which are water-insoluble conditioning agents, is destroyed. It can serve to keep each of the silicone particles evenly dispersed in the shampoo composition to improve the stability and conditioning effect over time.

In addition, since the dialkylaminoalkylmethacrylate polymer of the present invention has a cationic property, the dialkylaminoalkylmethacrylate polymer may be adsorbed on the hair to improve the softness and smoothness of the hair when the shampoo composition is used. Since the dialkylaminoalkylmethacrylate polymer particles dispersed in the aqueous solution exhibit a pseudoplastic behavior in which the viscosity is lowered under pressure, the dialkylaminoalkylmethacrylate polymer particles may be added to the shampoo composition to improve spreadability when applied to the hair.

The dialkylaminoalkyl methacrylate polymer may use Cosmetic Rheologies' Ultragel 300 or 3V Sigma's Synthalen CR, which is dispersed in oils such as mineral oils and ester oils and nonionic surfactants, and Salcare SC95 by Ciba Specialty Chemicals. Alternatively, Salcare sc96 may be used.

In the present invention, the content of the dialkylaminoalkylmethacrylate polymer is preferably 0.05 to 5% by weight based on the total weight of the composition. This lowers the conditioning effect and stability improvement when the content is less than 0.05% by weight, and when it exceeds 5% by weight, it gives a damp feeling to the hair and inhibits the appearance of the luxurious pearly inherent in the shampoo composition containing the pulping agent. Because it can.

In addition, the shampoo composition according to the present invention may further contain additives such as preservatives, thickeners, viscosity adjusters, pH adjusters, fragrances, dyes, conditioning agents, etc., which can be used as a component of the shampoo composition. It is known so that those skilled in the art can easily purchase and use. As an example of a preservative, a mixture of methyl paraoxybenzoate, methylchloroisothiazolinone and methylisothiazolinone (trade name: Kathon CG, manufactured by Rohm & Haas, USA) may be used. As the thickener and the viscosity regulator, hydroxypropyl methyl cellulose, hydroxymethyl cellulose, sodium chloride, ammonium chloride, propylene glycol, hexylene glycol, and the like may be used. As the pH regulator, citric acid, sodium hydroxide, triethanolamine, etc. may be mentioned. have. As the dye, a water-soluble tar pigment or the like can be used, and additional 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.
