Problems solved by technology

[0003] The application of pearl powder in cosmetics is greatly restricted, because pearl powder contains more than 90% calcium carbonate, calcium carbonate 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, destroy the emulsification system and suspension system of cosmetics, and reduce the stability of products
The above reasons limit the addition and use of pearl powder in cosmetics, affect the combined development of cosmetics and pearls, make it difficult to make breakthroughs in the beauty and nutritional properties of cosmetics, and hinder the development of the cosmetics industry.

Embodiment 1

[0032] Take 200kg of PEG-1000 into the stirring pot, heat to 43°C, add 50kg of pearl powder with a particle size of less than 200 nanometers, stir evenly to make a pearl powder slurry; add the pearl powder slurry to the colloid mill and grind it fully, then add it to the stirring pot, Heat to keep the temperature at 86°C, add 50kg of 60g / L sodium silicate solution, stir for 20 minutes, slowly add 50kg of 10.7% sulfuric acid, stir for 40 minutes and then cool to below 40°C, discharge the liquid, and age for 46 hours After washing and filtering, drying and pulverizing by airflow, the pearl powder coated with dense silica is obtained.

Embodiment 2

[0034] Take 160kg of PEG-1000 into the stirring pot, heat to 48°C, add 40kg of pearl powder with a particle size of less than 200 nanometers, stir evenly to make a pearl powder slurry; add the pearl powder slurry to the colloid mill and grind it fully, then add it to the stirring pot, Heat to keep the temperature at 88°C, add 40kg of 60g / L sodium silicate solution, stir for 20 minutes, slowly add 40kg of 10.7% sulfuric acid, stir for 40 minutes and then cool to below 40°C, discharge the liquid, and age for 48 hours After washing and filtering, drying and pulverizing by airflow, the pearl powder coated with dense silica is obtained.

Abstract

The invention belongs to the field of cosmetics, in particular to dense silicon dioxide coated pearl powder. The pearl powder is prepared from PEG-1000, pearl powder, a sodium silicate solution and a sulfuric acid solution by pulping, grinding, costing, washing with water, drying and pulverizing with air flows, wherein the pearl powder is nano pearl powder of which the grain size is smaller than 200 nm. The invention has the advantage of simple process, and the provided dense silicon dioxide coated pearl powder has the advantages of good coating effect, complete coating and no floccules among granules and can be widely applied to emulsions and cream in cosmetics and beneficial to promoting the combination development of the cosmetics and pearls so as to greatly widening the application range of the pearl powder in the cosmetics.

Description

Technical field [0001] The invention belongs to the field of cosmetics, and specifically is a pearl powder coated with dense silica. Background technique [0002] Pearl has always been recognized as a good beauty product. Its beauty mechanism is that pearls contain various amino acids and trace elements required by the human body. The nutrients contained in pearls are similar to those required by human skin, and are easily absorbed by the body. The effect of beauty care. The pearl powder prepared after pearl processing is the most common way to apply pearl beauty. [0003] The application of pearl powder in cosmetics is greatly restricted, because pearl powder contains more than 90% calcium carbonate. Calcium carbonate is a demulsifier that can destroy the emulsification system of cosmetics; pearl powder contains more than 20 trace elements , Directly added to cosmetics will greatly increase the ionic strength of cosmetics, destroy the emulsification system and suspension system ...
