Speaking of talcum powder, many of our friends may feel unfamiliar with it, but speaking of baby powder, I believe many friends should know about it. Talcum powder is one of the important raw materials for making many baby powders. I wonder if you know the composition of talcum powder and what are the specific uses of talcum powder? Now, let us all learn about it together and increase our knowledge in this area.

Talcum powder has a great role to play. It is used in many things in our lives, such as cosmetics used by our female friends, various types of paper, etc. These are part of its role. The following is a detailed introduction to the composition and uses of talcum powder. Friends who don’t know about it can take a look.

1. Overview.

The main ingredient of talcum powder is talc.

CAS No.： 14807-96-6

This product is made from magnesium silicate salt, a mineral talc family talc. The main component is hydrous magnesium silicate, which is crushed, treated with hydrochloric acid, washed and dried.

Talc Main ingredients Talc Hydrous magnesium silicate Molecular formula Mg3[Si4O10](OH)2 Talc belongs to the monoclinic system Crystals are pseudo-hexagonal or rhombic flakes Occasionally usually dense blocks, blades, radial, fibrous aggregates Colorless and transparent or white Due to a small amount of impurities, it appears light green, light yellow, light brown or even light red; cleavage surface has a pearly luster Hardness 1 Specific gravity 2.7~2.8

Talc has excellent physical and chemical properties such as lubricity, anti-stickiness, flow-aiding, fire resistance, acid resistance, insulation, high melting point, active chemical properties, good hiding power, softness, good gloss, strong adsorption, etc. Due to the layered crystal structure of talc, it has the tendency to split into scales and special lubricity. A high Fe2O3 content will reduce insulation.
