A barium sulfate-based powder is produced by bringing barium ions (A) into contact with sulfate ions (B) in the presence of one or more metallic ion species (C) selected from the group consisting of lithium ions, sodium ions, potassium ions, magnesium ions, calcium ions, zinc ions, and aluminum ions. Thus, barium sulfate-based powders having various characteristics and thus satisfying functional requirements for cosmetics can be obtained.

Stick-shaped solid cosmeticcomprises a wax with a melting point of 45&#xb0; C. or higher and liquid oil, wherein the hardness of top portionis 0.07 N to 0.38 N and the hardness of boundary portion, which is a border between a retained portion in inner holderand a portion outside of the inner holder, is 0.03 N to 0.31 N higher than the hardness of the top portion, and wherein the hardness gradually increases from the top portionto the boundary portion. Thus, the stick-shaped solid cosmetichas smooth spreadability and excellent product strength.

A first subject of the present invention is an insoluble powder characterized in that a zeta-potential is a negative value. It is preferable that barium sulfate is a main ingredient in the insoluble powder. It is preferable that an average primary particle diameter is 3 to 100 &#x3bc;m, and an aspect ratio is 3 to 250 in the insoluble powder. It is preferable that the insoluble powder is a metal-doped barium sulfate powder obtained by reacting a barium ion and a sulfate ion in the presence of a metal ion. It is preferable that the metal ion is one or more selected from the group consisting of a lithium ion, a sodium ion and a zinc ion in the insoluble powder. A second subject of the present invention is a skin barrier function recovering powder, or a skin roughening preventing and improving powder, which comprises the aforementioned powder. A third subject of the present invention is a skin external composition characterized in that a content of the aforementioned powder is 1 to 40% by weight.

A composite powder containing a powdery base and aluminum hydroxide adhered to at least a portion of the surface of the base, wherein said adhered aluminum hydroxide in the form of a spherical and net structure is comprised preferably in a large amount. In case of using in powdery cosmetics, this composite powder hides wrinkles, pore openings and hard texture of the skin, and thus maintains the correcting effect of the troubled morphology of the skin. Thus, it exerts excellent effects of imparting natural gloss and color tone to the makeup coating without darkness, being superior in a feeling of 'elasticity' and transparency, and the like, compared to the conventional products. The effect of the above object can be more enhanced by the surface treatment such as a further surface treatment by silicon on the surface of said composite powder.

A method is provided for producing an impact resistant solid cosmetic such as cheek rouge, powder, foundation and two way foundation by compacting powder materials into a dish mold. The powder materials are compression molded into a dish mold under a pressure of 200-300 kgf/cm at a temperature of 10-30&deg; C. The powder materials contain 0.1-50.0 wt % of a spherical organopolysiloxane elastomer having a JIS A hardness of 60-100, and a mean particle size of 0.1-200 &mgr;m. The cosmetic optionally contains 1.0-30.0 wt % of an oily ingredient.

Method of producing an impact resistant solid cosmetic composition

The invention provides an external-use composition imparting no sticky sensation in use, particularly an external-use composition for a cosmetic composition exhibiting excellent retention during use, by finding a gelling agent for an oily ingredient, particularly for silicone oil. The external-use composition contains a spherical powder (mean particle size: 0.1-200 &mgr;m) of organopolysiloxane elastomer having a JIS A hardness of 1.0-30.
