DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair shampoo composition which is a cleansing agent for hair and scalp, and more particularly, has excellent foaming properties and good combability after washing and rinsing with fingers and after drying. The present invention relates to a hair shampoo composition which is non-greasy, has excellent set properties, gives firmness and natural gloss to hair, and has excellent stability over time.

[0002]

2. Description of the Related Art Conventionally, hair shampoo compositions have been compounded with cationic polymers such as dimethyldiallylammonium chloride and cationic cellulose ether in order to improve fingering during washing and rinsing. However, the shampoo composition containing these cationic polymers forms a complex with the surfactant, which is a washing component, and adheres to or remains on the hair during hair washing. The conditioning effect was insufficient due to the occurrence or roughness. Therefore, in recent years, silicones such as dimethylpolysiloxane, polyether-modified silicone, alkyl-modified silicone, and amino-modified silicone have been used in combination in order to impart a conditioning effect after shampooing (Japanese Unexamined Patent Publication No. Sho.
6-72095, JP-A-63-307811, JP-A-2-247113, and JP-A-2-273.
612, JP-A-3-188016, JP-A-3-184906, JP-A-4-36225 and JP-A-4-234309. However, when these silicone compounds are used, there has been a problem that the foaming properties are extremely deteriorated, and the setting of the hair after washing and drying is deteriorated, so that it is difficult to apply a permanent wave. Furthermore, the hair could not be given a firm and natural shine.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, is excellent in foaming properties, has good finger passing during hair washing and rinsing, and good comb passing after drying, and has a sticky, non-sticky and settability. Gives hair a firm and natural shine while being excellent,
An object of the present invention is to provide a hair shampoo composition having excellent stability over time.

[0004]

That is, the present invention provides:
a. The difference R _C -R _A between the 30% particle size R _A and the 70% particle size R _C is 3
μm or less or 50% particle size difference between the R _B and 95% particle diameter R _D R
0.1 to 20 wt% metal soap particles, wherein the _D -R _B is 6μm or less, b. 2 to 30% by weight of an anionic or amphoteric surfactant and c. A cleaning composition comprising 0.1 to 5% by weight of a cationic polymer.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The metal soap fine particles used in the present invention are polyvalent metal salts of fatty acids. Examples of the fatty acids include lauric acid, myristic acid, palmitic acid, stearic acid, and behenic acid. Palmitic acid and stearic acid, and examples of the polyvalent metal atom include magnesium, calcium, zinc, aluminum, iron and the like, and preferably magnesium, calcium and zinc. The difference R _C -R _A between the 30% particle size _RA and the 70% particle size R _C is 3 μm or less or the 50% particle size R _B and 95%
The difference R _D -R _{B from} the particle size R _D is 6 μm or less, preferably R _C -R _A is 2 μm or less, or R _D -R _B is 3 μm or less. If R _C -R _A is greater than 3 μm or R _D -R _B is greater than 6 μm, the stability of the system with time, the resilience from low temperatures, and the foam quality deteriorate.

Here, the term "30% particle diameter _RA" means that 30% of the particles in the total weight of the metal soap particles are smaller than the particle diameter. For example, zinc stearate which is a general metal soap shown in FIG. 3.2 μm, which is the particle size at 30% in the particle size distribution and the cumulative (%) in the particle size cumulative graph, is defined as _RA . R _B , R _C, and R _D are similarly defined, and are 5.3 μm, 8.3 μm, and 19.6 μm, respectively. Therefore, R _C -R _A and R _D -R _B are 5.1 μm, 1
4.3 μm. That is, the lower the values of R _C -R _A and R _D -R _B , the narrower the range of the particle size distribution. Further, in the metal soap fine particles used in the present invention, 1
When the content of particles having a particle size larger than 0 μm is 4
%, More preferably substantially no particles having a particle size larger than 10 μm.

Incidentally, a general particle size distribution measuring method is used for measuring the particle size distribution. For example, sieving, sedimentation, microscopy, light scanning, laser diffraction scattering, and the like are mentioned. In the method of measuring metal soap fine particles used in the present invention, measurement is performed on finer particles with high accuracy. An optical scanning method, a laser diffraction scattering method, and the like, which can perform the above, are preferably used.

[0008] The metal soap fine particles of the present invention are usually prepared as follows. That is, a crystal transition of a metal soap that produces an aqueous solution containing 0.001 to 20% by weight of an alkali metal salt or an ammonium salt of a fatty acid and an aqueous solution or dispersion containing 0.001 to 20% by weight of an inorganic metal salt. A metal soap slurry is prepared by mixing at a temperature equal to or lower than the starting temperature, and then the slurry is subjected to a drying treatment at a temperature equal to or lower than the crystal transition starting temperature of the metal soap. Here, the crystal transition onset temperature is a temperature at which the crystal structure of the metal soap starts to change. For example, in a heat absorption graph by differential thermal analysis of zinc stearate in FIG. The temperature at the intersection C of A and the extension line B of the gradient after the endothermic end is taken as the crystal transition start temperature. The crystal transition onset temperature is 100 ° C. for zinc stearate and 94 ° C. for calcium stearate.
° C, and 73 ° C for magnesium stearate.
