We manufacturers and supplier of High purity Talc powder (Soapstone powder).It is largely composed of the mineral talc, thus is rich in magnesium. It is produced by dynamo thermal metamorphism and metasomatism, which occur in the zones where tectonic plates are sub ducted, changing rocks by heat and pressure, with influx of fluids, but without melting. Talc powder for cosmetic application, for Agro products as carrier and also for Pharma application IP and BP grades without black particles.

It imparts multiple actual properties to this mineral and makes it important for multiple employment. Soapstone powder India operates and keeps on being utilized in a variety of means.
