Description

Calciumpolycarbophil is a high-quality, cross-linked polycarboxylic acid polymer in its calcium salt form, widely recognized for its exceptional water-absorbing and swelling properties. This material is crucial for formulators seeking reliable, non-systemic agents to modify rheology and control moisture in sensitive applications. It serves as a key functional ingredient for leading manufacturers in the pharmaceutical, nutraceutical, and advanced personal care industries, where product performance and regulatory compliance are paramount.

Application

• Pharmaceutical Excipient: Primarily used as a super-disintegrant and binder in tablet formulations to promote rapid disintegration and drug release.
• Bulk-Forming Laxative: Serves as the active pharmaceutical ingredient (API) in over-the-counter and prescription products for constipation relief, functioning by absorbing water to form a soft, hydrated gel.
• Dietary Supplement & Nutraceutical Agent: Incorporated into fiber supplements and weight management products to promote a feeling of fullness and support digestive health.
• Personal Care & Cosmetics: Utilized as a thickener, stabilizer, and moisture-retention agent in creams, lotions, and topical gels.
• Medical Device & Wound Care: Applied in hydrogel dressings and other medical devices for its high fluid absorption capacity and biocompatibility.
• Industrial Applications: Functions as a water-absorbing polymer in specialty adhesives, agricultural products, and other industrial formulations requiring moisture control.

Quality Control

Our Calciumpolycarbophil is manufactured under strict quality management systems. We offer grades compliant with major pharmacopeial standards, including USP-NF and other relevant specifications for pharmaceutical and food applications. All batches undergo rigorous analytical testing for identity, assay, heavy metals, microbial limits, and performance characteristics. A comprehensive Certificate of Analysis (COA) is provided with each shipment to ensure full traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance.
