Abstract

The invention discloses a water-dispersed boron nitride powder for cosmetics and a preparation method thereof. The method uses synthesized hexagonal boron nitride coarse powder as a raw material, pre-disperses it in a surfactant aqueous solution, and performs surface activation by means of equipment grinding. centrifuging, washing, taking the upper layer powder of the filter, adding it to a hydrophilic surface modifier solution for surface modification, drying, crushing, and sieving to obtain a water-dispersed hexagonal boron nitride powder. This powder has excellent dispersibility in water. It is used in cosmetic oil-in-water cream/emulsion, skin care gel, mask essence, skin care water (spray), sunscreen spray, hair products and other non-washing products to improve skin Silky feeling, enhance delicate, bright white and other makeup effects. It is an excellent cosmetic additive raw material.

Description

technical field [0001] The invention relates to a water-dispersed boron nitride powder for cosmetics and a preparation method thereof, which belongs to the field of surface-modified cosmetic materials and aims to improve the application and stability of hydrophobic hexagonal boron nitride in water-based cosmetic systems, and finally The prepared water-dispersed boron nitride powders all meet the requirements of the 2007 edition of China's "Hygienic Standards for Cosmetics", and the preparation method is simple and easy to produce. Background technique [0002] Around 1940, Japan applied hexagonal boron nitride to cosmetics for the first time, but it was regarded as a luxury product for a long time. With the development and popularization of synthesis technology, the synthesis of hexagonal boron nitride is no longer difficult. The reduction of cost has made boron nitride widely used in cosmetics. Boron nitride is used in almost all the products that lead the cosmetics indust...
