Description

Hair conditioning solid cleaning composition {Solid cleansing compound for conditioning hair}

The present invention relates to a hair conditioning solid cleaning composition, and more particularly to a solid cleaning composition containing acyl glutamate in the group consisting of cationic surfactants, cationic polymers, amphoteric surfactants, silicones or mixtures of two or more thereof. The present invention relates to a hair conditioning solid cleansing composition capable of imparting a conditioning function by adding any one selected component to prevent hair entanglement and reducing hair lifting due to static electricity even when used for washing hair.

Human hair is composed of keratin, or sulfur-containing fibrous protein, and the isoelectric point of hair is in the range of pH 3.2 to 4. Therefore, since the hair is usually negatively charged, the combing of the hair becomes inconvenient after using the soap, and there is a problem in that it takes time and additional time to use a shampoo, a rinse combination shampoo or a rinse even after using the soap. The use of soap for hair cleaning has been greatly reduced.

In the case of shampoos, acyl glutamate could be used to add a conditioning effect, and hair entanglement could be greatly improved, and the effect was further improved when manufactured by adding more silicone.

However, in the case of solid detergents such as soaps, the use of acyl glutamate used in shampoos does not solve the problems such as tangling and stiffness of the hair. Without, there has been a need for hair conditioning solid cleaning compositions that can be used as a substitute for conventional shampoos.

Accordingly, the present invention is provided to more efficiently solve the problems of the prior art as described above, the object is to acyl glutamate to cationic surfactants, cationic polymers, amphoteric surfactants, silicones or mixtures of two or more thereof It is an object of the present invention to provide a hair conditioning solid cleaning composition which improves hair entanglement and reduces the generation of static electricity by adding any one component selected from the group consisting of.

In order to achieve the above object, the hair conditioning solid cleaning composition according to the present invention is selected from the group consisting of a cationic surfactant, a cationic polymer, an amphoteric surfactant or a mixture of two or more thereof in a solid cleaning composition containing acyl glutamate. Any one conditioning agent, including acyl glutamate of Formula 1, sodium cocoyl isethionate and water, 1.0 to 20% by weight of the conditioning agent, 10 to 40% by weight of the acyl glutamate, the sodium cocoyl ISE It contains thionate in an amount of 40 to 80% by weight and comprises water as the remaining amount.

(In the above meal,

R is an alkyl group of C ₆ to C ₂₂ ; M ⁺ ₁ and M ⁺ ₂ is H ^+, Na ^+, K ⁺ or triethanolamine).

In addition, the composition of the present invention is characterized in that it further comprises a silicone agent in an amount of 0.1 to 5% by weight based on the total weight of the composition.

Hereinafter, the present invention will be described in detail.

Acyl glutamate is particularly excellent in human stability and excellent in water resistance and foaming ability. As an amino acid-based surfactant, it has two hydrophilic groups and is in a form close to a natural lipid structure. The acyl glutamate used in the present invention is represented by the following Chemical Formula 1.

Formula 1

In the above formula,

R is an alkyl group of C ₆ to C ₂₂ ; M ⁺ ₁ and M ⁺ ₂ is H ^+, Na ^+, K ⁺ or triethanolamine. R is used as lauroyl, cocoyl, cocoyl, myristoyl, stearoyl, and the like, and in this case, monosodium or disodium is preferable.

In the present invention, when the acyl glutamate is used in an amount of less than 10% by weight based on the total weight of the composition, there may be a problem in that expected effects cannot be obtained in solidification, skin irritation, foaming power, etc., and used in an amount of more than 40% by weight. In the case of the lack of moisture there is a difficulty in solidification and there may be a problem that results in worse conditioning function. Accordingly, the acylglutamate of the present invention is preferably used in an amount of 10 to 40% by weight based on the total weight of the composition. More preferably used in an amount of 10 to 20% by weight.

The sodium cocoyl isethionate of the present invention is a component derived from coconut, has excellent cleaning power, gives a rich and soft foam, and is an excellent raw material used in soft cleansing soap products, which leaves a soft feeling on the skin after use. There is this. In order to exhibit the above-mentioned efficacy in the present invention, it is preferable to use it in an amount of 40 to 80% by weight. More preferably in an amount of from 60 to 70% by weight.

Meanwhile, as the component for imparting a conditioning function in the present invention, any one component selected from the group consisting of cationic surfactants, cationic polymers, amphoteric surfactants, silicones or mixtures of two or more thereof may be used.

Among these, cationic surfactants are cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, benzalkonium chloride, benzeonium chloride, lauryldimethylbenzyl ammonium chloride and picoline benzyl chloride. Ammonium or mixtures thereof and the like can be used. As the cationic polymer, dimethyldialkylammonium chloride, acrylamide or a mixture thereof may be used. Amphoteric surfactants include cocodimethylcarboxymethylbeta, cocamidopropylbetaine, cocobetaine, laurylbetaine, laurylamidopropylbetaine, oleylbetaine, lauryldimethylcarboxymethylbetaine, lauryl Dimethylalphacarboxyethylbetaine, cetyldibetaylcarboxymethylbetaine, laurylbis- (2-hydroxyethyl) carboxymethylbetaine, stearylbis- (2-hydroxypropyl) carboxymethylbetaine, oleyldimethyl Gamma-carboxypropylbetaine, laurylbis- (2-hydroxypropyl) alpha-carboxyethylbetaine, sulfobetaincodimethylsulfopropylbetaine, lauryldimethylsulfoethylbetaine, laurylbis- (2 -Hydroxyethyl) sulfopropylbetaine, amidosulfobetaine, cocodimethylpropylsultine, stearyldimethylpropylsultaine, cocoamidodimethylpropylsultaine, stearylamidodimethylpropylsultine, laurylamidepropylhydroxy The other set, cocoa shown propyl hydroxyl other facilities, or a mixture thereof may be used. In addition, as the silicone agent, polyalkylsiloxane, polyarylsiloxane, polyalkylarylsiloxane, polyethersiloxane copolymer or mixtures thereof may be used.

Conditioning agent selected from the group consisting of the cationic surfactant, cationic polymer, amphoteric surfactant, or a mixture of two or more thereof is less than 1.0% by weight based on the total weight of the composition, the conditioning effect is insignificant to improve the problems such as entanglement If there is more than 20% by weight, the effect is no longer improved, there is a problem that is not efficient. Thus, the conditioning agent is preferably used in an amount of 1.0 to 20% by weight based on the total weight of the composition. More preferably, the cationic surfactant is used in an amount of 0.5 to 1.5% by weight, the cationic polymer is 0.5 to 1.0% by weight, and the amphoteric surfactant is 0.5 to 1.5% by weight. In addition, the silicone agent which can be used to improve the hair entanglement with the conditioning agent is preferably used in an amount of up to 5% by weight based on the total weight of the composition, more preferably in an amount of 1.0 to 2.5% by weight.

Hereinafter, the hair conditioning solid cleaning composition will be described in more detail by Examples 1 to 6 and Comparative Example 1, but the present invention is not limited only to these examples.
