Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing composition, and more particularly to a cleansing composition for hair having a milky appearance, being stable, having good usability, removing scalp and skin stains, and having a massage effect. Composition.

[0002]

2. Description of the Related Art Conventionally, it has been difficult to mix an inorganic powder such as a clay mineral into a cosmetic.
Widely used, including foundations.
Also in the detergent composition, various inorganic powders are blended into the liquid or sheet-shaped detergent composition, paying attention to the oil absorption of the clay mineral or the like. For example, in recent patents, Patent No. 2567824 issued from L'Oreal, JP-A-5-310439 and JP-A-10-45565 issued from Kao, and JP-A-10-45565 issued from Lion are disclosed. 10-237496, JP-A-9-316
The technology described in Japanese Patent No. 485/485 and the like is known. In these conventional techniques, titanium dioxide, talc, mica, silica, bentonite, biophyllite, kaolin and the like are used as the inorganic powder.

[0003] On the other hand, when a cleaning agent having a pH of more than 8 is used for hair, the cuticle is greatly damaged, and a soap-based cleaning agent has a poor feeling of use (smoothness). Therefore, as the detergent composition, it is preferable that the pH of the system is 8 or less in terms of safety to hair and feeling of use.
However, it is sometimes difficult to stably mix a clay mineral in a liquid detergent particularly at a system pH of 8 or less depending on the type of surfactant. Therefore, in order to improve the stability, it is necessary to increase the viscosity, but if the viscosity is too high, there is a drawback that the ease with which the product can be taken out of the container, spreads to the hair, and the speed of foaming is deteriorated. .

[0004] Further, conventionally, as an opacifying agent for a detergent composition, a compound which can stably blend a fatty acid ester of ethylene glycol has been mainly used. However, when only a fatty acid ester of ethylene glycol is blended as an opacifying agent, the composition becomes opaque and has a unique glaring feeling. For this reason, there has been a demand for an opacifying agent that eliminates the glaring feeling and takes on an emulsion.

The present invention has been made in view of the above-mentioned conventional circumstances, and has an opaque, non-glaring, milky appearance having an appropriate viscosity, and has stability and usability (smoothness). It is an object of the present invention to provide a detergent composition containing an inorganic powder excellent in (1).

[0006]

Means for Solving the Problems As a result of intensive studies on the above problems, the present inventors have found that by mixing a specific amount of a specific kaolinite, the emulsion has an opaque and non-glaring emulsion-like appearance, It has been found that a detergent composition containing an inorganic powder having good stability and usability (smoothness) can be obtained irrespective of the type of activator, and the present invention has been completed.

That is, according to the present invention, 0.1 to 10.0% by weight of a delaminated kaolinite is blended,
H is 4 or more and 8 or less and the viscosity at 37 ° C. is 10
A cleaning composition characterized by being at least 00 [mPa · s] and at most 10,000 [mPa · s].

Hereinafter, the present invention will be described in detail. The delaminated kaolinite used in the present invention is a layered silicate mineral formed by stacking 1: 1 layers of a dioctahedral type having Al as an octahedral cation and having a chemical formula of Al ₂ Si ₂ O _5. (O
H) ₄ (However, a single hexagonal plate-shaped particle represented by ₄ (however, it may contain some Fe) is powder having a particle diameter of less than 2 μm as it is or slightly aggregated. As kaolinite, there is also a laminate type kaolinite. However, the use of a laminate type kaolinite is inferior in stability. Delaminated kaolinite is commercially available, for example, as Kaopake 20 (trade name, manufactured by Dry Branch Kaolin). FIG. 1 is a schematic diagram when comparing the microstructure of delaminated kaolinite by electron microscopy with the microstructure of laminated kaolinite. In the figure, (a) shows a microstructure of laminated kaolinite, and (b) shows a microstructure of delaminated kaolinite.

The amount of the delaminated kaolinite used in the present invention is 0.1 to 10.0% by weight, preferably 0.5 to 8.0% by weight. If it is less than 0.1% by weight, opacity of appearance or lack of glaring is not achieved, and if it exceeds 10.0% by weight, stability is affected.

The composition of the present invention has a pH of 4
Not less than 8 and a viscosity at 37 ° C. of 1000
It is necessary to be not less than [mPa · s] and not more than 10,000 [mPa · s]. When the pH of the composition exceeds 8,
It is unsuitable in terms of safety and usability. In addition, the composition of the present invention has a viscosity at 37 ° C. of 1000 [mPa · s] or more and 10,000 [mPa ·
s] The following is intended for emulsions.

[0011] The cleaning composition of the present invention contains hexametaphosphate and / or citrate as a dispersing agent in an amount of 0.01%.

The detergent composition of the present invention further comprises a humectant derived from a dihydric or higher polyhydric alcohol or sugar in an amount of 0.1 to 2%.
