Conditioning Shampoo Composition

The present invention relates to a conditioning shampoo composition comprising a cleaning surfactant and a conditioning agent.

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. Accordingly, 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.

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. No. 6,165,955). (H), there is a disadvantage that the stability of the product is reduced when using a small amount, the stability of the product is improved when using a large amount, but due to the coarse feeling of the pulping agent, the soft texture is lowered when rinsing, the smooth texture falls when wet, and the hair is dry There was a disadvantage of being rough.

U.S. Patent No. 5,955,066 uses fatty alcohols, fatty acids, fatty alcohol derivatives and fatty acid derivatives to improve the conditioning effect and stability of the shampoo, but this causes the viscosity to drop at low temperatures, which causes the low temperature stability of the shampoo.

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 due to the formation of precipitates in combination with the anionic surfactant which is a cleaning component, and the amount of the cationic surfactant is limited.

Therefore, 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 stability over time and low temperature storage stability.

In order to achieve the above technical problem, the present invention is a conditioning shampoo composition comprising a cleaning surfactant and a conditioning agent, characterized in that it comprises a quaternary ammonium cationic surfactant represented by the formula (1) as the conditioning agent It provides a conditioning shampoo composition.

In Formula 1, R ₁ is any one selected from the group consisting of a straight alkyl group having 12 to 18 carbon atoms, a branched alkyl group, an alkenyl group, and the like, and R ₂ and R ₃ is an alkyl group having 1 to 3 carbon atoms independently of each other, R ₄ is (CH ₂ CHOHCH ₂ O) _n H, n is 1 to 10, X is a group consisting of a halogen group, a sulfate group and an acetate group It is any one selected from.

Hereinafter, the present invention will be described in detail.

The shampoo composition according to the present invention includes a cationic surfactant into which a glyceryl group represented by Formula 1 is introduced as a conditioning agent.

Referring to Formula 1, the cationic surfactant used in the present invention is a structure of a quaternary ammonium compound, in which all four substituents of ammonium ions are composed of an alkyl group and the like. In particular, in the present invention, the cationic surfactant has at least one hydrophilic group in the substituent, and the hydrophilic group is a structure in which at least one glyceryl group is condensed and repeated, and the number of repeating units is 1 to 10.

Such quaternary ammonium cationic surfactants impart excellent conditioning effects to the hair, and in particular, the added glyceryl group, which is a hydrophilic group, further enhances the moisturizing and conditioning effects of the hair.

In addition, the shampoo composition comprising the quaternary ammonium cationic surfactant is improved aging stability and low temperature storage stability. In particular, the quaternary ammonium cationic surfactant does not form a precipitate even when an anionic surfactant is used as a cleaning component, unlike a conventional cationic surfactant, and in this case, the conditioning effect of the shampoo composition is excellent, Its aging stability and low temperature storage stability are improved.

Conventionally, cationic surfactants, when anionic surfactants are used as cleaning components, form precipitates, and therefore, their amount of use is limited because the conditioning effects as well as the cleaning power are lowered and the stability of the composition is lowered.

But. 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. The micelles can be formed. Since the pseudo-nonionic composite surfactant improves the problems that occur when the cationic surfactant and the anionic surfactant are used at the same time, the amount of the cationic surfactant can be increased even in the presence of the anionic surfactant. Such pseudo-nonionic composite surfactants have surfactant activity such as solubilizing power, detergency, emulsifying power, dispersing power, and surface tension lowering ability when conditions such as structure and mixing concentration of anionic surfactant and cationic surfactant are well controlled. Excellent effect can be obtained at low cmc concentration.

The cationic surfactant is preferably used 0.1 to 10% by weight based on the total weight of the composition. When the content is less than 0.1% by weight, the conditioning effect and stability improvement effect by the cationic surfactant is lowered. When the content is more than 10% by weight, the hair feels damp and there is a fear of precipitation and phase stability. It may be inappropriate.

The shampoo composition according to the present invention comprises 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 anionic surfactant, nonionic surfactant and 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 kinds thereof may be used, but the present invention is not limited thereto.

As the nonionic surfactant that can 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. .

Preferably, the present invention may further add a cationic polymer, a silicone compound or a mixture thereof to further improve the conditioning effect.

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. .

As the natural cationic polymer that can be used in the present invention, for example, cationic guar such as guar hydroxypropyltrimonium chloride, 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, PVP-dimethylaminoethylmethacrylate copolymer, acrylic acid-dimethyldi Allyl ammonium chloride copolymer, acrylamide-dimethylamino ethyl methacrylate methyl chloride copolymer, trimethylaminoethyl methacrylate polymer and the like may be used, but are not limited thereto.

In the shampoo composition of the present invention, the content of the cationic polymer is preferably 0.01 to 5.0% 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 is not sufficiently exhibited. When the content is higher than 5.0% by weight, the cationic polymer is excessively adsorbed on the hair and the scalp to give a damp feeling.

In addition, the silicone compound is not particularly limited as long as it can be generally used in shampoo compositions, for example, water-insoluble non-volatile dimethicone, cyclomethicone, aminated silicon, amodimethicone, trimethylsilyl amodi One or more components commonly referred to as silicones such as methicone and derivatives thereof can be used.

In the present invention, the content of the silicone compound is preferably 0.1 to 5.0% by weight, more preferably 0.5 to 3.0% by weight based on the total weight of the composition. This is because when the content is less than 0.1% by weight, a sufficient conditioning effect is not exerted, and when the content is higher than 5.0% by weight, there may be a problem in formulation formation.

Preferably, the shampoo composition according to the present invention may further comprise a pearl composition. These pearl compositions are used to impart a brilliant pearl metallic luster to the appearance of the shampoo and to keep the dispersed water-insoluble conditioning agent stable in the product for a long time, and the pearl composition is used for anionic surfactants, nonionic surfactants, and pearlizing agents. Include.

The content of the pulping agent is preferably 0.1 to 5.0% by weight, more preferably 1.0 to 3.0% by weight based on the total weight of the shampoo composition. This is because when the content is less than 0.1% by weight, no pearly feeling occurs, and when it exceeds 5.0% 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 in a solid state at room temperature is melted and then mixed with an anionic surfactant or a nonionic surfactant and added to the shampoo composition in a liquid state, or melted and added to the shampoo composition in a crystalline state obtained through a conventional cooling crystallization method. Can be.

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, and those skilled in the art It is known enough to be able to easily purchase and use. 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.
