[TECHNICAL FIELD OF THE INVENTION]

FIELD OF THE INVENTION The present invention relates to conditioning shampoo compositions, and more particularly to anionic silicone and cationic surfactants, which have excellent effects in restoring the physical state of the hair surface, preventing further damage of damaged hair, scalp hypoallergenic and hair conditioning. A conditioning shampoo composition comprising a complex.

[Private Technology]

Shampoo is a cosmetic product for hair that is used to decontaminate the scalp and hair and to keep the hair clean and beautiful.In addition to cleaning purposes, it is easy to comb, softness, smoothness, gloss, and the friction of the hair surface, antistatic, hair It is used for additional purposes such as protection.

Shampoos generally comprise oils, cationic surfactants, cationic polymers or silicones.

Cationic surfactants act to reduce friction during hair rinsing to smoothen and increase hair adsorption of other water-insoluble conditioning materials. However, unlike cationic polymers, they also stimulate the scalp and tend to precipitate by forming complexes with anionic polymers used as stabilizers.

Silicones are often used to provide conditioning effects, but they are difficult to apply to real products. That is, the use of a small amount of silicon causes a stiffness in the hair in the rinsing and wet conditions, there is a problem to inhibit the foaming force and at the same time reduce the product stability. U.S. Patent Nos. 4,364,837, 4,341,799, and 4,465,639 disclose shampoo compositions comprising silicone, but there are limitations to address hair stiffness when using shampoo.

In addition, International Patent Publication No. 9210162 discloses a shampoo composition using silicone in combination with a cationic polymer, and US Patent No. 4,704, 271 discloses a shampoo composition using quaternary ammonium or amine having three long-chain alkyl groups. European Patent No. 0312234 discloses a shampoo composition comprising silicone and a long chain acyl derivative or amine oxide, US Patent No. 5,034,218 discloses a shampoo composition containing quaternary nitrogen having two silicones and two long chain alkyl groups, and also a British patent. No. 2164558 discloses a composition comprising cationic silicone and amino aliphatic heteropolysaccharides. The above patents are characterized by the use of cationic components to enhance the adsorption and conditioning effect on the hair, but these components are strongly bonded to the hair and scalp and are not easily washed and can be accumulated and adsorbed (Chemical and Physical Behavior of Human Hair, 3 ^rd ED., Clarence R. Robbins, Springer Verlag, P. 177), causes problems such as scalp itching, and still suffers from hair stiffness during shampoo use.

Therefore, there is a need for a study on a conditioning shampoo composition which can reduce scalp irritation due to the use of silicone and hair stiffness during shampoo use.

Accordingly, it is an object of the present invention to provide a conditioning shampoo composition which can reduce scalp irritation and stiffness of hair during shampoo use and at the same time provide a conditioning effect on dry hair.

The present invention also provides a conditioning shampoo composition comprising an anionic silicone and a cationic surfactant composite.

In order to achieve the above object, the present invention provides a conditioning shampoo composition comprising an anionic silicone and a cationic surfactant complex.

In another aspect, the present invention is a method for producing a conditioning shampoo composition comprising an anionic silicone and a cationic surfactant complex,

The anionic silicone of the present invention is used to reduce the stiffness in the wet and dry hair to facilitate combing and to provide a conditioning effect to the hair. The anionic silicone may be organic silicone prepared by introducing a reactor selected from the group consisting of phthalic anhydride, succinic anhydride, phosphoric acid and sulfamic acid to the dimethicone copolyol main chain. As an example of anionic silicone, dimethicone copolyol phthalate, dimethicone copolyol succinate, dimethicone copolyol phosphate, dimethicone copolyol sulfate, and mixtures thereof may be included, but are not limited thereto. It doesn't happen. Anionic silicone may be included in the conditioning shampoo composition in 0.5 to 5% by weight, the content of which is less than 0.5% by weight of the conditioning effect may be insignificant and when it exceeds 5% by weight can be rapidly reduced foaming force.

The cationic surfactant of the present invention is mixed with the anionic silicone prior to the introduction of the anionic polymer to form a complex. The complex reduces scalp irritation of the cationic surfactant and at the same time improves the problem that the cationic surfactant reacts with the anionic polymer and precipitates. Anionic silicone and cationic surfactant composites can be prepared by mixing and stirring anionic silicone and cationic surfactant. As an example of the cationic surfactant, it may be selected from the group consisting of cetrimonium chloride, stearamidopropyldimethylamine, disetyldimethylammonium chloride and mixtures thereof, but is not limited thereto.

Experimental Example 1: Friction Force Measurement on Hair

After the compositions of Example 1-4 and Comparative Example 1-2 were treated to the hair, the frictional force of the hair was measured. If the hair is damaged, the cuticles may crack or float, resulting in a rough surface. 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, the shampoo composition was treated, dried and dried, followed by a friction tester ((1) Miniature Tensile Tester MTT600: Dia-Stron Ltd., (2) RheoWin Software Rev 3.3a: Dia-Stron Ltd., (3) Extension Speed: 100mm / min) was used to measure the physical state change of the hair surface. The results are shown in Table 2 below.

Experiment Example Comparative example One 2 3 4 One 2 Friction force (N) * 1 time 0.40 0.41 0.42 0.39 0.77 0.98 Episode 2 0.48 0.38 0.39 0.38 0.64 1.12 3rd time 0.39 0.36 0.37 0.36 0.63 1.07 Average 0.42 0.38 0.39 0.38 0.68 1.06 % Reduction 60 64 63 64 35 0 (1) *: Friction force: surface smoothness => damaged and rougher surface, frictional force is larger (2) Reduction rate (%) = AB / A, (A: Hair of Comparative Example 2 Friction force of the tress, B: friction force of the hair tress of Examples 1-4 and Comparative Example 1)

In Table 2, the shampoo composition of Examples 1-4 had a smoother surface of hair than the shampoo composition of Comparative Example 1 using conventional silicone. This indicates that the anionic silicone has significantly restored the physical state of the hair roughened by the damage compared to the conventional silicone. In addition, in Comparative Examples, Comparative Example 1 using dimethicone was found to have a 35% reduction in frictional force as compared to Comparative Example 2 without using silicon, thereby improving the feeling of silicone shampoo.

Experimental Example 2: Hair Damage Prevention Effect

Combing is a cosmetic treatment that is repeatedly performed in daily life, and accumulates hair damage. 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.

Each of the compositions of Examples 1-4 and Comparative Examples 1-2 was treated in a hair tray, dried and dried, followed by a combing force tester : 2000mm / min) was used to measure the damage prevention effect on the hair. The results are shown in Table 3 below.

Experiment Example Comparative example One 2 3 4 One 2 Combing force (N) * 1 time 0.48 0.49 0.52 0.46 0.69 0.89 Episode 2 0.53 0.47 0.53 0.44 0.69 0.88 3rd time 0.58 0.52 0.50 0.44 0.70 0.91 Average 0.53 0.49 0.52 0.45 0.69 0.89 % Reduction 40 44 41 49 22 0 (1) *: Combing force: Combing force => Combing force is greater as the surface is damaged and rougher (2) Reduction rate (%) = AB / A, (A: of Comparative Example 2 Combing force of hair tress, B: Combing force of hair tress of Examples 1-4 and Comparative Example 1)

In Table 3, it was confirmed that the shampoo composition of Example 1-4 significantly reduced the combing force compared to the shampoo composition of Comparative Example 1-2. Therefore, it can be seen that the shampoo composition containing anionic silicone is very excellent in preventing hair damage.

Experimental Example 3: Conditioning Effect of Hair

The conditioning effect of the shampoo compositions of Examples 1-4 and Comparative Examples 1-2 was tested. The experiment was conducted on 15 men and women, and the conditioning effect (drying and feeling) of hair after shampoo was evaluated by the following evaluation criteria. The results are shown in Table 4 below.
