Description

Glyceryl Polyacrylate, Hispagel 100 is a high-performance, cross-linked polymer derived from glyceryl and acrylic acid, known for its exceptional water-absorbing and thickening properties. This material is critical for formulators seeking to control rheology, enhance stability, and manage moisture in a wide range of industrial and consumer products. It is an essential ingredient for manufacturers in the personal care, pharmaceutical, and specialty chemical industries who require reliable, high-quality functional polymers.

Application

• Personal Care & Cosmetics: Primarily used as a superabsorbent polymer and thickener in products like diapers, feminine hygiene items, and as a gelling agent in creams, lotions, and hair gels.
• Pharmaceuticals: Employed as a disintegrant in tablet formulations and as a hydrogel base for topical drug delivery systems and wound dressings.
• Agriculture & Horticulture: Functions as a soil conditioner and water-retention agent to improve moisture availability for plants and reduce irrigation frequency.
• Industrial Applications: Serves as a viscosity modifier and water-blocking agent in adhesives, sealants, coatings, and cable gel compounds.
• Laboratory & Research: Used in biotechnology and research for gel electrophoresis, chromatography media, and as an absorbent material.

Quality Control

Our Glyceryl Polyacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters such as absorption capacity, viscosity, residual monomers, and particle size distribution to ensure consistent performance and purity. Certificates of Analysis (COA) documenting full specifications are available upon request. We can support compliance with relevant frameworks including ISO and GMP where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
