Description

Zinc Stearate USP

Zinc Stearate USP is a high-purity, pharmaceutical-grade Zinc soap used as a lubricant, release agent, and anti-adherent in solid oral dosage forms. With excellent hydrophobic properties and compatibility with a wide range of excipients, it is a proven processing aid in tablet and capsule manufacturing. Zinc Stearate

• Is a USP-compliant excipient for solid oral dosage forms
• Functions as a lubricant, glidant, and anti-adherent in tablet and capsule production
• Is insoluble in water, ensuring stability during processing and storage
• Reduces die wall friction, improves powder flow, and facilitates tablet ejection
• Is manufactured under Good Manufacturing Practice (GMP) conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and supporting technical data

Chemically, Zinc Stearate is a Zinc salt of Stearic acid, typically appearing as a fine, white, hydrophobic powder. It is insoluble in water and ethanol, making it ideal for use where moisture sensitivity or controlled release characteristics are desired.

In pharmaceutical manufacturing, Zinc Stearate USP is used in:

• Tablet and capsule formulations as a lubricant to prevent sticking and improve powder flow
• Granulation processes to enhance blend uniformity and ensure consistent die fill
• Powder blends and direct compression formulations to reduce capping and lamination issues
• Coating processes as an anti-adherent or dusting agent to improve handling

Zinc Stearate’s low reactivity and excellent thermal stability allow it to be incorporated into a wide variety of formulations without affecting drug release profiles or chemical stability.

CarboMer supplies Zinc Stearate USP with tight control over heavy metals, free fatty acid content, and microbiological quality to meet or exceed USP monograph requirements. Each batch is fully traceable and manufactured under GMP conditions for pharmaceutical applications.

The material is packaged in sealed, moisture-protected, tamper-evident containers. Available in standard and bulk pack sizes for R&D, pilot, and commercial-scale production. Minimum order quantities (MOQ), lead times, and regulatory documentation are available upon request.

Each lot is tested for identity, assay, acid value, heavy metals, zinc content, and microbial purity. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and supporting technical documents are provided with every shipment.

As with all CarboMer excipients, Zinc Stearate USP is supported by formulation consulting, regulatory expertise, and global sourcing reliability to help you deliver high-quality solid dosage products to market efficiently.
