Talc powder helps alleviateExcess stomach acid, along with other fillers and extenders, primarily consists of hydrated magnesium silicate, specifically magnesium trisilicate hydrate, with the molecular formula Mg3(Si4O10)(OH)2. Food-grade talc belongs to the monoclinic crystal system. Crystals are often pseudo-hexagonal or rhomboidal in shape, occurring occasionally. They typically form dense leaf-like, radiating, massive, or fibrous aggregates. They are colorless and transparent or white, but may appear light green, light yellow, light brown, or even light red due to trace impurities; they exhibit a pearl-like luster on cleavage surfaces. Hardness of 1, specific gravity of 2.7 to 2.8.

Talc powder molecular formula: Mg3[Si4O10] or 3Mg·4SiO2·
Physical and Chemical Properties:
Talc powder, a physical property, is a fine powder that ranges from pure white, silver white, pink, to pale yellow. It is produced by selecting, crushing, and drying talc. It is soft and slippery, a typical sheet-like filler with good electrical insulation properties, excellent heat resistance without heat conduction, stable chemical properties, and resistance to strong acids and alkalis. It also boasts strong oil absorption and covering power.
The quality of talcum powder, primarily depends on the purity of its chemical composition. The purer the chemical composition, the higher the quality of the talcum powder; conversely, it is lower in quality.
