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.

Embodiment 1

[0032] Take 200kg of PEG-1000 and add it to a stirring pot, heat it to 43°C, add 50kg of pearl powder with a particle size of less than 200nm, and stir evenly to make a pearl powder slurry; add the pearl powder slurry to a colloid mill for full grinding, and then add it to the stirring pot , heated to 80°C, slowly add 50kg of 60g / L sodium metaaluminate solution and 50kg of 10.7% sulfuric acid at the same time under the condition that the addition rate remains consistent, stir for 60 minutes and then cool down to below 40°C, release the feed liquid, and age After 48 hours, it was washed with water, filtered, dried and crushed by air flow to obtain pearl powder coated on the surface of alumina.

Embodiment 2

[0034] Take 160kg of PEG-1000 and add it to a stirring pot, heat it to 48°C, add 40kg of 200nm pearl powder, and stir evenly to make a pearl powder slurry; add the pearl powder slurry to a colloid mill for full grinding, add it to a stirring pot, and heat to 83 ℃, slowly add 40kg of 60g / L sodium metaaluminate solution and 40kg of 10.7% sulfuric acid at the same time under the condition that the addition rate is consistent, stir for 60 minutes and then cool down to below 40℃, release the feed liquid, age for 48 hours and wash with water Filtration, drying and crushing by air flow can obtain the pearl powder coated with alumina surface.

Abstract

The invention belongs to the field of cosmetics, in particular to 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, the pearl powder, the 60 g / L solution of sodium metaaluminate and 10.7 percent sulfuric acid solution, wherein the pearl powder is nano pearl powder with a grain diameter of less than 200 nanometers. The 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 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 emulsification system and s...
