Embodiment

[0131] Hereinafter, the present invention will be described more specifically by way of Examples and Comparative Examples. However, the present invention is not limited to these Examples.

[0132] 1. Preparation of Boron Nitride Composite Powder

preparation Embodiment 1

[0134] 500 g of boron nitride (SHP7, Mizushima Ferroalloy Co., Ltd.) having an average particle diameter of 7 μm was added to 2833 ml of purified water, and the mixture was thoroughly stirred and heated to 60°C. The pH of the mixture was then adjusted to 4.0 with hydrochloric acid at a concentration of 5% by weight to obtain a suspension.

[0135] Then, 402 g of titanium oxide particles (Tipaque CR-50, Ishihara Sangyo Kaisha, Ltd.) with an average particle diameter of 0.3 μm, 69 g of iron oxide yellow particles with an average particle diameter of 0.4 μm (TAROX LL-100P, Titan Kogyo, Ltd. .), 23g of iron oxide red particles (TAROX R-516P, Titan Kogyo, Ltd.) with an average particle diameter of 0.4 μm and 6 g of iron oxide black particles (TAROX BL-100P, Titan Kogyo, Ltd.) with an average particle diameter of 0.4 μm .) Add to 2833ml of purified water and mix thoroughly until evenly dispersed. The mixture was then added to the above suspension, stirred for more than 17 hours, an...

preparation Embodiment 2

[0140] 1000 g of the boron nitride composite powder obtained according to Preparation Example 1 was collected in a Henschel mixer (FM5C / I, Mitsui Mining Co., Ltd.). 20 g of methylhydrogenpolysiloxane (KF-9901, Shin-Etsu Chemical Co., Ltd.) was added thereto with stirring, and stirred for 20 minutes.

[0141] The powder was then taken out from the Henschel mixer and dried at 110° C. for 15 hours to obtain a hydrophobized boron nitride composite powder which had been surface-treated with methylhydrogenpolysiloxane (hydrogen polydimethylsiloxane). The surface appearance of the powder is beige.

[0142] Further, measure the hue of the powder as L * 73.a * 14 and b * twenty three.

Abstract

A cosmetic composition comprising a boron nitride complex powder in which particles of metal oxide are attached to at least a part of the surface of a base material consisting of boron nitride. The metal oxide is preferably a combination of titanium dioxide, yellow iron oxide, red iron oxide and black iron oxide. Preferred compositions include liquid or powder foundation, lipstick, eye shadow, eye liner and mascara. The cosmetic composition comprising a cosmetic powder is capable of imparting smoothness to the touch, lively finish with fine texture and natural glow, and adhesion to the skin when applied to the skin.

Description

technical field [0001] The present invention relates to a cosmetic composition containing boron nitride complex powder, especially a cosmetic composition for makeup. More specifically, the present invention relates to a cosmetic composition incorporating boron nitride complex powder that can provide a smooth touch when applied to the skin, a beauty finish with fine texture and natural luster, and adhesion to the skin as a necessary ingredient. Background technique [0002] Generally, flaky powders of mica, talc, kaolin, etc. are introduced into cosmetic cosmetics such as foundations to improve adhesion to the skin. Also, to adjust the color tone, white pigments such as titanium oxide and color pigments such as iron oxide are used. By adding titanium oxide, uneven skin tone such as spots and freckles can be covered. However, in this case the skin may appear dull and it is not easy to provide a transparent and natural finish. In addition, since sufficient smoothness and lu...
