Description

Calcium Polycarbophil is a high-quality, cross-linked polyacrylic acid derivative supplied as the calcium salt. This pharmaceutical-grade excipient is valued for its exceptional water-absorbing and gel-forming properties, making it a critical component in controlled-release and moisture-managing formulations. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and advanced medical device industries seeking reliable and consistent performance in solid and semi-solid dosage forms.

Application

• Pharmaceutical Tablets & Capsules: As a super-disintegrant to promote rapid breakdown and drug release, or as a controlled-release matrix former.
• Bulk-Forming Laxatives: A key active ingredient in over-the-counter and prescription products for constipation relief, where it absorbs water to form a soft, hydrated gel.
• Medical & Wound Care: Used in advanced wound dressings and hydrocolloid adhesives to manage exudate and maintain a moist healing environment.
• Nutraceutical & Dietary Supplements: Incorporated into fiber supplements and other health products for its bulking and water-retention capabilities.
• Cosmetic & Personal Care: Functions as a thickener, stabilizer, and moisture-retention agent in creams, lotions, and gels.
• Industrial Applications: Employed as a water-absorbing polymer in specialty adhesives, agricultural products, and other industrial formulations requiring moisture control.

Quality Control

Our Calcium Polycarbophil is manufactured and tested to meet stringent USP-NF (United States Pharmacopeia) monograph standards, ensuring it is suitable for pharmaceutical applications. Every batch undergoes rigorous quality testing, including assay, identification, and impurity profiling. A comprehensive Certificate of Analysis (COA) documenting purity, physicochemical properties, and microbiological quality is available upon request to support your regulatory and quality assurance needs.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect performance.
