Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cosmetic containing spherical organic composite clay mineral powder. More specifically, the present invention relates to a cosmetic containing a spherical organic composite clay mineral containing a water-swellable clay mineral and a water-soluble substance, and exhibiting excellent feel (smoothness, moistness) and moisturizing properties.

[Conventional technology]

Water-swellable clay minerals are used as dispersion stabilizers in paints, pharmaceuticals, and cosmetics by taking advantage of their swelling and gelling properties. It is preferably used in powder dispersion products and emulsion products (eyeliner, mascara, emulsion, cream, nail enamel). It is generally used in the form of a gel dispersed in an aqueous solvent.

In addition, water-swollen clay minerals undergo glabellar reactions with organic polar molecules and cationic molecules such as various alcohols, amines, and water-soluble polymers, forming clathrate compounds. However, such clathrate compounds have so far only been used in the form of gels dispersed in aqueous solvents. Furthermore, even if the powdered form is incorporated into cosmetics as is, the granules often become amorphous and tend to aggregate due to the filtration and centrifugation processes that take place during powdering. It has a drawback that it has a strong rough feel and is difficult to incorporate into cosmetics, especially where the feel of the product is important.

On the other hand, water-soluble substances are often incorporated into cosmetics for the purpose of replenishing moisture to the skin, but when incorporated in large amounts, they often cause stickiness. In formulation systems without water, they have poor solubility and compatibility, and often evaporate over time. Therefore, it could not be incorporated into this type of product.

[Problem that the invention seeks to solve]

As a result of intensive studies to improve the shortcomings of the prior art, the present inventors have found that a clay mineral containing a water-swellable clay mineral and a water-soluble substance, and further contains a spherical organic composite clay mineral having a spherical shape. By doing so, we have found that in addition to providing an excellent feeling of use (smoothness and moistness), it also exhibits excellent moisturizing properties, and based on this knowledge, we have completed the present invention.

Examples include sodium acyl β-alanine, glucthione, and pyrrolidone carboxylic acid.

Among these, polyhydric alcohols and mukopolyMW4 are particularly preferred.

In carrying out the present invention, one or more kinds of these water-soluble substances are arbitrarily selected.

The spherical organoclay mineral according to the present invention is a spherical powder containing the above water-swellable clay mineral and a water-soluble substance, and has a particle size of 2 to 20 μm.

The amount of water-swellable clay minerals in the total amount of spherical organic clay minerals is 25 to 99.95% by weight, preferably 50 to 99.9 parts by weight, and the amount of moisturizing agent in the total amount of spherical organic clay minerals is 0. 0.05 to 70% by weight, preferably 0.1 to 50% by weight.

Although the method for producing the organic composite clay mineral of the present invention is arbitrary, it is preferable to use the spray drying method as described below because it is the simplest method and an organic clay mineral with a well-shaped spherical shape can be obtained.

That is, the water-swellable clay mineral and the water-soluble substance are dissolved by dissolving the above-mentioned water-soluble substance in an aqueous solvent, further dispersing the above-mentioned water-swellable clay mineral to form a gel, and then spray-drying the gel. This is a method for obtaining a spherical organoclay mineral containing.

In the above gel containing a water-soluble substance and a water-swellable clay mineral, the concentration of the water-swellable clay mineral is preferably 20% by weight or less; if the concentration is higher than that, the gel viscosity becomes too high and the water-swellable clay mineral is not sprayed during spray drying. It is difficult to send liquid through the nozzle, and the nozzle may become clogged. A particularly preferred concentration range is 1 to 10% by weight.

In addition, the concentration of water-soluble substances in the above gel is 0.001~
5% by weight is preferred.

When preparing a gel, it is preferable to sufficiently stir the water-swellable clay minerals, etc. so that they are sufficiently dispersed and swollen. If the dispersion and swelling are insufficient, the nozzle may become clogged during spray drying, or the obtained This is not preferable since the spherical organoclay minerals may become irregular.

For the spray drying, a general WX spray drying method such as a disk type, a pressure nozzle type, or a two-fluid nozzle type can be applied.

In either case, the inlet air temperature during spraying is preferably in a temperature range where the humectant is thermally stable, and is approximately 150°C to 200°C.

Further, the exhaust gas temperature is regulated by the flow rate of spray from the nozzle, etc., but a rough estimate of around 100°C is sufficient.

The spherical organic clay mineral thus obtained is a nearly spherical powder having a structure in which primary particles of a water-swellable clay mineral aggregate, and has a particle size of 2 to 20 μm. Furthermore, the more transparent the appearance of the gel prepared in advance and the higher the viscosity (for example, in the case of laponite), the more uniform and smooth the particle surface morphology becomes.

When a polyhydric alcohol or the like is selected as a water-soluble substance in producing a spherical organoclay mineral by the above method, the polyhydric alcohol is included in the glabella of the water-swellable clay mineral. This can be confirmed by the widening of the long distance in X-ray diffraction.

In addition, when mucopolysaccharides and the like are selected as water-soluble substances, they do not enter the glabella of clay minerals, but are adsorbed to the surface of the primary particles of water-swellable clay minerals and are included in spherical organoclay minerals. be done.

In addition, when a water-soluble substance is dissolved in a organic solvent outside the water, another method for producing this spherical organic composite clay mineral is to prepare a spherical water-swellable clay mineral in advance, and then clathrate the water-soluble substance. There is a way to do it. That is, when a water-dispersed gel containing only a water-swellable clay mineral is spray-dried, a spherical water-swellable clay mineral containing nothing is obtained. If this is dispersed in an organic solvent in which a water-soluble substance has been dissolved in advance, and then the organic solvent is evaporated, the dissolved water-soluble substance will permeate and be included in the spherical water-swellable clay mineral. The spherical organic composite clay mineral thus prepared is a powder that is exactly the same as the powder obtained by spray-drying a water-dispersed gel of a water-soluble substance and a water-swellable clay mineral. The organic solvent at this time may be any general low boiling point substance other than water, such as methanol, ethanol, acetone, chloroform, etherhexane, etc. Examples of water-soluble substances that dissolve in organic solvents include polyhydric alcohols and quaternary ammonium salts. The amount of the spherical organoclay mineral used in the present invention to be incorporated into the cosmetic is arbitrary depending on the form of the cosmetic, and is generally 0.1 to 80 M%. In the case of emulsified or dispersed products, the content is generally 0.1 to 50% by weight, and in the case of powdered or pressed powder products, the content is generally 0.1 to 70% by weight.

In addition to the above-mentioned spherical organoclay minerals, the cosmetic of the present invention contains
Other ingredients commonly included in cosmetics can be included in qualitative and quantitative ranges that do not impair the effects of the present invention. Such ingredients include oils, waxes, pigments,
