Soapstone Powder Manufacturer in India | Speciality Geochem
Soapstone powder is a hydrated magnesium silicate mineral processed from high-purity talc ore, and Speciality Geochem manufactures industrial mineral powder and micronised grades for plastics, ceramics, paints, paper, cosmetics, and pharmaceutical applications. Operating from Udaipur, Rajasthan since 1996, the company is located in India’s primary talc-producing belt, a region responsible for nearly 80% of the country’s talc output. Our manufacturing operations are ISO-certified and BIS-certified, with every batch tested for MgO content, particle size, moisture, and GE brightness before dispatch.
Speciality Geochem supplies soapstone powder in 200 mesh, 300 mesh, 400 mesh, and 600 mesh grades, with customised micronised specifications available for bulk industrial orders. As a talc powder manufacturer, we supply pan-India and export-grade material for industrial mineral applications requiring high brightness, controlled particle distribution, and stable chemical composition.
What is Soapstone Powder?
Soapstone powder is a hydrated magnesium silicate mineral with the chemical formula Mg3Si4O10(OH)2, also known as talc powder, steatite powder, or French chalk. With a Mohs hardness of 1, it is the softest naturally occurring mineral and is valued for its lubricity, thermal resistance, chemical inertness, smooth texture, and fine particle dispersion properties. Rajasthan produces nearly 80% of India’s talc reserves, making Udaipur a major soapstone processing and mineral manufacturing hub. The mineral’s hydrophobic structure helps resist moisture in plastics, rubber, paints, paper, ceramics, and cosmetic formulations. Industrial soapstone powder remains thermally stable at temperatures approaching 1300°C, making it suitable for refractories, electrical steatite components, and high-temperature ceramic applications.

Applications by Industry
Soapstone powder is widely used in plastics, paints, ceramics, paper, rubber, cosmetics, and pharmaceuticals for its high MgO content, thermal resistance, smooth texture, and chemical stability. Speciality Geochem supplies high-brightness industrial grades with controlled particle size and consistent performance.
Plastics and Polymer Industry
Soapstone powder reinforces polypropylene and engineering plastics by improving tensile strength, dimensional stability, and heat resistance. Its lamellar particle structure reduces mould shrinkage while supporting higher filler loading in industrial polymer compounds.
Paints and Coatings
Soapstone powder functions as an extender pigment that improves opacity, whiteness, and suspension stability in coating systems. Fine particle distribution reduces settling during storage and enhances surface smoothness in decorative and industrial paints.
Ceramics and Refractories
Soapstone powder improves thermal shock resistance and minimises firing shrinkage in ceramic formulations. Steatite-based compositions are widely used for electrical insulators, kiln furniture, and refractory components exposed to elevated temperatures.
Rubber Manufacturing
Soapstone powder acts as an anti-blocking and anti-sticking agent during rubber processing operations. The mineral improves mould release performance while maintaining elasticity and dimensional consistency in industrial rubber products.
Paper Industry
Soapstone powder is used as a filler mineral that improves printability, smoothness, and sheet opacity in paper manufacturing. High GE brightness grades support premium paper applications requiring consistent surface finish and whiteness.
Cosmetics and Personal Care
Refined soapstone powder grades are used in talcum powder, baby powder, and cosmetic formulations due to their smooth texture and moisture absorption properties. Controlled purity supports safe use in personal care manufacturing applications.
Pharmaceutical Industry
Soapstone powder functions as an anti-caking agent and excipient in pharmaceutical tablet manufacturing processes. Its chemically inert composition supports stable mineral performance in moisture-sensitive pharmaceutical formulations and coating systems.
Construction Materials Industry
Soapstone powder is added to construction compounds, wall putty, and industrial fillers to improve smoothness and application consistency. The mineral enhances surface finish while supporting moisture resistance in cement-based formulations.
Electrical and Steatite Components
Steatite-grade soapstone powder is processed into ceramic electrical components requiring thermal stability and insulation performance. The mineral maintains structural integrity under high-temperature operating conditions in electrical and refractory applications.

Our Manufacturing Process
Step 1 — Raw Material Sourcing
Soapstone ore is sourced from certified Rajasthan mines and tested for MgO content, whiteness, moisture percentage, and mineral purity before entering production processing.
Step 2 — Primary Crushing Process
Large soapstone lumps are processed through jaw crushers to reduce particle size while preserving mineral structure and minimising contamination during production handling.
Step 3 — Grinding and Micronisation
Ball mills and Raymond mills grind soapstone into 200, 300, 400, and 600 mesh grades with controlled particle size distribution for industrial applications.
Step 4 — Air Classification Process
Air classifiers and vibrating screens separate particles according to mesh precision requirements to maintain uniform dispersion in coatings, plastics, and ceramics.
Step 5 — Quality Control Testing
Every production batch undergoes testing for GE brightness, pH value, specific gravity, moisture content, and chemical composition before final packaging approval.
Step 6 — Packing and Final Dispatch
Finished soapstone powder is packed in 25 kg, 50 kg, and jumbo HDPE bags for safe domestic supply, bulk industrial delivery, and export shipment.
