Zinc Stearate Manufacturers

As a dedicated Zinc Stearate Manufacturers in India, we produce this compound in pharmaceutical, cosmetic, and industrial grades with the process controls, grade-specific testing, and compliance documentation that buyers working inside regulated and performance-critical manufacturing environments genuinely need.

Its molecular formula is  C₃₆H₇₀O₄Zn, molecular weight 632.33 g/mol, and is produced through the controlled fusion of zinc oxide with stearic acid, or through a double decomposition reaction involving sodium stearate and zinc sulphate. The production method matters because it directly influences particle morphology, surface area, and how the compound ultimately performs inside rubber blends, polymer systems, or cosmetic powder matrices. The result is a fine, white, hydrophobic powder thermally stable, practically insoluble in water, and carries surface-active lubricating properties that make it effective across a range of demanding industrial and formulation applications.

Zinc Stearate Manufacturers in India

Zinc content and particle size are two parameters that procurement teams occasionally treat as secondary to overall purity, and that assumption tends to create problems further down the line. Zinc content directly governs stabilising activity in polymer systems. Particle size governs how uniformly the compound distributes through a rubber blend or cosmetic powder base. A batch that clears a basic purity check but sits outside the acceptable range on either of these will behave differently inside your process, sometimes subtly, sometimes not.

As trusted Zinc Stearate Manufacturers in India, every batch is tested for purity, zinc content, particle size distribution, loss on drying, and free fatty acid levels before dispatch. CoA, MSDS, and full grade compliance documentation are included with every order as standard.

Core Strengths of the Product: 

  • Functions as a highly effective internal and external lubricant in rubber and plastic processing, reducing mould friction and improving surface release.

  • Provides thermal stabilisation in PVC compounds, extending the processing window and preventing early heat-induced degradation.

  • Imparts water repellency to paper coatings, construction materials, and powder formulations through its hydrophobic surface properties.

  • Delivers consistent mould release in compression moulding, injection moulding, and rubber vulcanisation processes.

  • Acts as a texture-improving and thickening agent in cosmetic formulations, contributing smoothness and slip without heaviness.

  • Chemically compatible with most polymer systems, APIs, and cosmetic actives under standard processing and storage conditions.

  • Recognised under applicable pharmaceutical, cosmetic, and industrial regulatory frameworks across major global markets.

Calcium Stearate Suppliers in India

Use Across Industries: 

As established Calcium Stearate Suppliers in India, we supply across every industry this compound serves with grade-specific material and documentation to match each application: 

  • Rubber processing internal lubricant and activator in tyre, seal, and gasket manufacturing.

  • PVC stabilisation used in pipe, profile, and cable compounds alongside calcium or barium-zinc systems.

  • Mould release prevents adhesion in injection and compression moulding operations.

  • Cosmetics texture and slip improvement in pressed powders, foundations, and eyeshadows.

  • Pharmaceutical tablet lubricant where the zinc content is within API compatibility limits.

  • Abrasives surface lubricant in sandpaper manufacturing to prevent clogging during grinding.

  • Paper and board coating improves surface smoothness and print receptivity.

Zinc Stearate Exporters in India

International shipments of metal soap compounds carry compliance requirements that go well beyond standard freight paperwork import classifications, cosmetic ingredient declarations, and pharmaceutical excipient sourcing standards, all of which differ by destination, and a single documentation gap holds up consignments that are otherwise ready to move.

As experienced Zinc Stearate Exporters in India, every shipment leaves with a fully verified package  CoA, MSDS, commercial invoice, packing list, zinc content declaration, and destination-specific compliance papers prepared before dispatch. Grade and source declarations for cosmetic or pharmaceutical dossier requirements are provided on request.
