TL;DR: In this paper, a method used for preparing sericite powder used for cosmetics is described, which consists of following steps: shear flocculation, wherein a sericaite quartz powder ore pulp with a mass concentration of 10 to 60% is delivered into a stirring sanding dispersing multifunction machine for shearing and stirring, and an inhibitor, a pH value regulating agent, a surface conditioning agent, and a cation collector are added successively so as to complete preliminary modification of sericites and formation of hydrophobic flocculations; flotation and pur

TL;DR: In this article, an easy-to-disperse sericite for cosmetics is described, where the surface treating agent is obtained by mixing a modifying agent and a dispersing agent in a mass ratio of 1 to (1-10), the modifying agent is a mixture of any two or three of N-octyl triethoxysilane, polymethylhydrosiloxane and polydimethyl siloxane; the dispersing agents is isopropanol.

TL;DR: In this article, the influence of sodium-modification pretreatment on the adsorption of anionic dye by amphoteric modified bentonite, three kinds of adsorbent materials, including sodiummodified bentonite and ammonite-based bentonite pretreated by sodium modification, were firstly synthesized and characterized, and afterwards their performance and mechanism for acid dye, Acid Yellow 11, were investigated comparatively.

TL;DR: In this paper, raw diatomite (RD) was used for the adsorption of cationic red X-GRL from aqueous solutions. But, the results showed that the RD could uptake more XGRL than DC due to its higher content of fine particle and therefore, due to higher surface area available for adorption.
