Problems solved by technology

In recent years, some medicines, especially health food, have diversified appearance requirements. Pearlescent coating can make solid preparations look more beautiful and arouse people's desire to eat when taking medicine. Mica powder is commonly used in pearlescent coating materials, but when solid preparations are coated with pearlescent coatings, the conventional method used is to mix film-forming agents, lubricants, colorants and mica powder together and then form a suspension for coating. In practical applications, mica powder Not only has a good pearlescent effect, but also has a good color-shielding effect, so that after the tablet and health food are coated, there will be a white pearlescent effect, and the color of other colored colorants in it will not appear, no matter what color the color is Table

Abstract

The invention relates to a one-time coloring premixing agent with mica powder wrapped by a pearly-luster coating. The premixing agent is prepared from, by weight, 45-58 parts of hydroxypropyl methylcellulose, 12-18 parts of mica powder, 12-18 parts of a coloring agent, 7-10 parts of glyceryl triacetate, 5-8 parts of tween 80 and 5-8 parts of castor oil. Pigment is adopted for the coloring agent. Amanufacturing method comprises the steps that during mixing, firstly, the hydroxypropyl methylcellulose, the glyceryl triacetate, the tween and the castor oil are mixed by a mixer, then the mica powder and the coloring agent are added, secondary mixing is conducted, and the premixing agent is obtained. By adopting the one-time coloring premixing agent with the mica powder wrapped by the pearly-luster coating, the problem can be effectively solved that pearly-luster powder covers the coloring agent, and the problem is solved that currently, when the mica powder is wrapped by the pearly-lustercoating, the color of the coloring agent is shielded; for solid preparations with appearance demands, particularly for health care products or food, the color can be evenly presented through the premixing agent.
