[0072] Heating in deionized water (or organic solvent) extracted from sumac [comprising one selected from sumac bark extract (CAESALPINIA SAPPAN BARK EXTRACT), sumac dry powder (CAESALPINIA SAPPAN STEM POWDER) or A mixture of more than one natural dye] to extract the dye solution, and concentrate the dye solution to vacuum-dry and prepare the dye. Put 10 parts by weight of hematoxylin into a 2L beaker, and drop into 100 parts by weight of deionized water and 30 parts by weight of CaCl 2 , to stir at 200rpm. At this time, the reaction temperature was set at 40° C., and potassium hydroxide was charged. The pH was adjusted to 7, and the solution was stirred, and when a precipitate started to appear, the above precipitate was dehydrated, dried, pulverized, and used as a pigment.

Abstract

The present invention relates to a method of preparing a colored gloss pigment using a natural dye. According to the present disclosure, the method may include preparing a dye from a dye material of natural dyes; titrating the dye with an inorganic salt solution and subsequently adjusting a pH neutral to prepare a natural pigment containing the dye; dispersing a substrate coated with a metal oxide into a DI water to form a substrate suspension; and introducing a pH adjusting agent and the natural pigment into the substrate suspension to coat a surface of the substrate with the natural pigment.

Description

technical field [0001] The present invention relates to the preparation technology of colored glossy pigments, and more specifically relates to the colored glossy pigments using vegetable natural dyes that can be used to prepare colored glossy pigments for cosmetics and a preparation method thereof. Background technique [0002] Organic pigments are characterized by a wide range of colors, vivid colors, and excellent tinting power, but are more expensive than inorganic pigments and have problems in terms of durability, heat resistance, and the like. [0003] Recently, organic pigments have been favored over inorganic pigments as environmental issues have become serious. Organic pigments are mainly used in paint, ink, rubber, fiber, paper, leather, cosmetics, etc. [0004] Among them, pigments for cosmetics are sensitive to changes in trends, so various products have been launched one after another. However, in contrast to this, due to environmental constraints, there are m...
