Problems solved by technology

[0003] The application of pearl powder in cosmetics is greatly limited, because pearl powder contains more than 90% calcium carbonate, which is a demulsifier that can destroy the emulsification system of cosmetics; pearl powder contains more than 20 kinds of trace elements , directly added to cosmetics will greatly increase the ionic strength of cosmetics and destroy the emulsification system and suspension system of cosmetics
The above reasons limit the openness of pearl powder in cosmetics, which affects the development of the combination of cosmetics and pearls, making it difficult to make breakthroughs in the beauty and nutritional properties of cosmetics, and hindering the development of the cosmetics industry.

Abstract

The invention relates to cosmetics, in particular to compound acne-removing pearl powder with an aluminum oxide-coated surface, which is prepared by pulping, grinding, coating, washing, drying and milling with fluid energy PEG-1,000, compound pearl powder, the solution of sodium metaaluminate and sulfuric acid solution, wherein the compound pearl powder is prepared by spraying plant extract onto nano pearl powder with a grain diameter of less than 200 nanometers and drying and crushing the nano pearl powder sprayed with the plant extract; and the plant extract is the mixed solution of pot marigold extract, parslane herb extract, aloes extract and liquoric root extract. The compound acne-removing pearl powder with the aluminum oxide-coated surface provided by the invention has the characteristics of simple process, good enveloping effect, complete coating and no floccules among particles, can be widely applied to emulsion and cream in the cosmetics and favorable for the combined development of the cosmetics, pearls and Chinese medicaments, and greatly expands the application range of the pearl powder in the cosmetics.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a compound acne-removing pearl powder coated on the surface of aluminum oxide. Background technique [0002] Pearls have always been recognized as a beauty product, and its beauty mechanism is that pearls contain various amino acids and trace elements needed by the human body. The nutrients contained in pearls are close to the nutrients needed by human skin, and are easily absorbed by the human body. The effect of beauty care. Pearl powder prepared after pearl processing is the most common way to use pearl beauty. [0003] The application of pearl powder in cosmetics is greatly limited, because pearl powder contains more than 90% calcium carbonate, which is a demulsifier that can destroy the emulsification system of cosmetics; pearl powder contains more than 20 kinds of trace elements , directly added to cosmetics will greatly increase the ionic strength of cosmetics and destroy the em...
