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 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

[0033] Take 50 kg of pearl powder with a particle size of less than 200 nanometers and spread it into a thin layer, take 4 kg each of calendula extract, purslane extract, aloe extract, and licorice extract, mix the extracts evenly, and spray to the pearls. Powdered, dried and jet crushed to obtain compound pearl powder;

[0034] Take 200kg of PEG-1000 and add it to a stirring pot, heat it to 45°C, add compound pearl powder, and stir evenly to make a pearl powder slurry; add the pearl powder slurry to a colloid mill to grind it fully, add it to the stirring pot, and heat to keep the temperature Between 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, cool down to below 40°C, release the feed liquid, age for 46 hours, wash and filter , dried and crushed by airflow to obtain the compound acne-removing pearl powder coated with dense silicon dioxide.

Embodiment 2

[0036] Take 38 kg of pearl powder with a particle size of less than 200 nanometers and spread it into a thin layer, take 3 kg each of calendula extract, purslane extract, aloe extract, and licorice extract, mix the extracts evenly, and spray onto the pearl powder , dried and jet crushed to obtain the compound acne-removing pearl powder;

[0037] Take 175kg of PEG-1000 and add it to a stirring pot, heat it to 48°C, add compound 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 the stirring pot, and heat to keep the temperature Between 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, cool down to below 40°C, release the feed liquid, age for 48 hours, wash and filter , dried and crushed by airflow to obtain the compound acne-removing pearl powder coated with dense silicon dioxide.

Abstract

The invention belongs to the field of cosmetics, and in particular relates to compound anti-acne pearl powder coated by compact silicon dioxide. PEG-1000, compound pearl powder, solution of sodium silicate and solution of sulfuric acid are subjected to the steps of beating, grinding, coating, washing, drying, and fluid energy milling to prepare the powder, wherein the compound pearl powder is prepared by spraying Chinese medicinal extracting solution to nanometer pearl powder, of which the grain size is less than 200 nanometers and drying and pulverizing the nanometer pearl powder, and the Chinese medicinal extracting solution is mixed solution of potmarigold calendula extracting solution, parslane herb extracting solution, aloes extracting solution and liquorice root extracting solution. The compound anti-acne pearl powder coated by the compact silicon dioxide has the advantages of simple process, good coating effect, complete coating and no floccus among granules, can be widely applied in emulsion and cream in the cosmetics, is favorable for promoting the combination of the cosmetics, pearls and traditional Chinese medicines and broadens the application range of the pearl powder in the cosmetics greatly.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a compound acne-removing pearl powder coated with dense silicon dioxide. 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, destroy the emulsificat...
