Description

Cream type shampoo composition {Cream-like shampoo composition}

The present invention relates to a cream type shampoo composition.

In general, various hair cosmetics are used to remove contamination of hair and scalp and keep them clean and beautiful. Among them, shampoo is generally used as a hair cosmetic, which is used to remove contaminants and contains an anionic surfactant having excellent cleaning power as a main component.

Recently, however, the hair is damaged and roughened by various factors such as frequent perm and dyeing, and thus the hair has been damaged and roughened.

Therefore, in order to provide a conditioning effect that prevents hair damage and improves softness to the shampoo, which emphasizes only the cleaning function in the related art, a hair conditioning shampoo has been further added with a conditioning agent in addition to the anionic surfactant, which is the main component of the shampoo. It has been put to practical use, and its use is increasing.

As the hair conditioning component, silicones, oils and derivatives thereof, cationic polymers, cationic surfactants and the like can be used. However, when insoluble and non-volatile silicones or oils are used, stabilizers such as carbomer, xanthan gum, clay, pearl composition, etc. must be used separately to maintain the dispersed state for a long time. There is a limit in the amount of the conditioning agent to maintain the stability, such as poor use and poor deterioration.

In order to solve this problem, U.S. Patent No. 6,080,708 discloses a composition in which an insoluble substance is stabilized by using crystalline hydroxy wax, but it is difficult to disperse and has a separate facility, and the crystal structure makes us feel and appearance. There is a problem of deterioration.

In addition, in the case of using a conventional cationic polymer or cationic surfactant, the precipitate is formed by combining with the anionic surfactant, which is a cleaning component, and the content thereof is low, and thus its usage is limited, and there is a difficulty in forming a lamellar structure. .

In order to solve this problem, US Pat. No. 6,077,816 discloses a composition prepared by stabilizing a conditioning agent by forming a lamellar structure using a liquid fatty acid and a liquid alcohol. There is a problem.

Therefore, the technical problem to be achieved by the present invention is to easily form a lamellar structure without the addition of additional additives, the contents are stable without sediment, good spreadability when applied to the hair, excellent feeling, and time-lapse stability according to temperature To provide a very excellent cream type shampoo composition.

In order to achieve the above technical problem, the cream type shampoo composition of the present invention is any one selected from the group consisting of amphoteric surfactants, nonionic surfactants and mixtures thereof, an auxiliary surfactant, anionic surfactant and It contains the quaternary ammonium cationic surfactant which introduce | transduced the glyceryl group represented by 1.

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

Hereinafter, the shampoo composition of the cream type of the present invention will be described in detail.

It is easy to form. Accordingly, a cream type formulation is formed, and the stability over time is also very good.

Auxiliary surfactants contained in the cream type shampoo composition according to the present invention include amphoteric surfactants, nonionic surfactants, and the like, and these may be used alone or in combination of two or more thereof. The content of the cosurfactant is preferably 1 to 20% by weight based on the total weight of the composition.

Examples of the amphoteric surfactant (or zwitterion surfactant) include betaine, amido betaine, sulfobetaine, ampoacetate, diampoacetate, propionate, glycinate, and the like. Each can be used individually or in mixture of 2 or more types. The nonionic surfactants include lauryl acid diethanolamide, palm oil fatty acid diethanol amide, palm oil fatty acid monoethanolamide, and the like, and these may be used alone or in combination of two or more thereof.

In addition, the anionic surfactant contained in the cream-type shampoo composition according to the present invention is sodium lauryl sulfate, ammonium lauryl sulfate, lauryl magnesium sulfate, sodium tridecyl sulfate, lauryl triethanolamine, polyoxyethylene lauryl as a cleaning component.

The content of the anionic surfactant is preferably 5 to 40% by weight based on the total weight of the composition. In this content range, the cleaning function can be properly exhibited, the lamellar structure can be easily formed, and the cleaning power is excellent.

The cationic surfactant contained in the cream type shampoo composition according to the present invention is a structure of a quaternary ammonium compound, in which all four substituents of ammonium ions are composed of alkyl groups and the like. In particular, at least one of the substituents is a hydrophilic group, 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 contain at least two or more glyceryl groups, which are hydrophilic groups, and interact with anionic surfactants in aqueous solutions, commonly referred to as pseudo-nonionic complex surfactants. Melting mixed micelles can be formed. This pseudo-nonionic composite surfactant forms a lamellar structure without forming a precipitate in the cream type shampoo composition containing the auxiliary surfactant. Such lamellar structures, in particular the lamellar structures bent in vesicles or onions, have a high zero shear viscosity in the form of densely arranged droplets, allowing the insoluble materials to be uniformly and stably suspended in the formulation. Low critical shear rate spreads easily during application and has the advantage of easy dispensing. In accordance with these features the lamellar structures exhibit a creamy formulation and significantly improve the stability over time, especially freeze-thaw stability. The quaternary ammonium cationic surfactant in which the glyceryl group is introduced is preferably used in an amount of 0.1 to 10% by weight based on the total weight of the composition. In this content range, lamellar structure formation by the pseudo-nonionic composite surfactant is easy and gives a soft feeling in use.
