Embodiment 1

[0053] Weigh TiO 2 : 3.4054g, Li 2 CO 3 : 0.24g, K 2 CO 3 : 1.355g, KCl: 5g, FeCl 2 4H 2 O: 0.34 g, mixed for about 10 minutes using a mortar. Calcined at 1000°C for 5 hours, immersed the calcined product in warm water at 80°C, and stirred for about 1 hour. The resulting powder was filtered off, and the powder was further stirred in warm water at 80° C. for about 15 minutes. The powder was filtered out and dried at 150°C for 1 hour. The composition formula of the obtained flaky brown pigment is K 0.835 Li 0.256 Ti 1.677 Fe 0.067 o 4 .

Embodiment 2

[0055] Weigh TiO 2 : 6.81g, Li 2 CO 3 : 0.48g, K 2 CO 3 : 2.71g, KCl: 11.388g, Fe(NO 3 ) 3 9H 2 O: 1.388 g, mixed for about 30 minutes using a mortar. Calcined at 950°C for 5 hours, immersed the calcined product in warm water at 80°C, and stirred for about 3 hours. The obtained powder was filtered off and dried at 150° C. for 1 hour. The composition formula of the obtained flaky brown pigment is K 0.835 Li 0.256 Ti 1.677 Fe 0.067 o 4 .

Embodiment 3

[0057] Weigh TiO 2 : 6.81g, Li 2 CO 3 : 0.48g, K 2 CO 3 : 2.71g, KCl: 11.388g, Fe(NO 3 ) 3 9H 2 O: 1.388 g, mixed for about 30 minutes using a mortar. Calcined at 1100°C for 5 hours, immersed the calcined product in warm water at 80°C, and stirred for about 3 hours. The obtained powder was filtered off and dried at 150° C. for 1 hour. The composition formula of the obtained flaky brown pigment is K 0.835 Li 0.256 Ti 1.677 Fe 0.067 o 4 .

Abstract

The present invention provides a pigment which uses lepidocrocite type plate-like titanic acid and a cosmetic containing the pigment. Specifically, the invention provides the plate-like brown pigment with a general formula of K3x+yLixTi2-x-yFeyO4 (but 0.2</=x</=0.3; 0.05</=y</=0.5).

Description

technical field [0001] The present invention relates to flaky brown pigments and cosmetics containing the pigments. Background technique [0002] Various coloring pigments are used in cosmetics. For example, use: flaky barium sulfate coated with iron oxide with no blooming phenomenon and good smoothness (Patent Document 1: Japanese Patent Laid-Open No. 2000-265154); excellent ultraviolet shielding effect, spreadability, orientation, A metal compound with excellent masking properties is coated and compounded with low-crystalline silica (Patent Document 2: Japanese Patent Application Laid-Open No. 11-11927); there is no darkening of the color tone during use, and the color tone can be maintained bright The coloring agent (Patent Document 3: Japanese Patent Laid-Open Publication No. 3-246210) that is surface-treated with a high degree of fluorine compound; iron-containing titanium dioxide that improves the anti-floating function of white pigments and colored pigments (Patent D...
