Abstract

The invention discloses a dry powder coating premix which is composed of a macromolecule film-forming material and a pearly-lustre pigment, and belongs to the technical field of medicines and food coatings. A pearly-lustre type coating premix is characterized by comprising the component of the dry powder coating premix which is composed of the macromolecule film-forming material, such as hydroxypropyl methyl cellulose, and the pearly-lustre pigment in a physically mixing manner, the premix is sprayed on surfaces of solid particles, pill cores, tablets and candies after being dissolved, and the surface of the premix has the pearl-like high-glossiness gorgeous color.

Description

[0001] technical field [0002] The invention relates to the technical field of coating solid preparations such as pharmaceutical preparations, health food, food, candy, etc., in particular to a pearlescent coating premix and a preparation method thereof Background technique [0003] The application of film coating materials composed of hydroxypropyl methylcellulose, plasticizers and colorants as film coatings for solid pharmaceutical preparations has been proposed. However, with the progress of society, people's quality of life and awareness of health care are also enhanced, and medicines, health food, food, etc. with health care functions emerge at the historic moment, and the pearlescent coating premix prepared by special technology can make The wrapped medicines, health foods and foods have pearl-like metallic luster and brilliant colors. [0004] As a mica-based pearlescent pigment, it is usually only used in industrial products, such as plastics, paints, etc.,...
