Description

Poly-Karaya CAS NO 80997-81-5 is a high-molecular-weight polysaccharide gum derived from the *Sterculia urens* tree, valued for its excellent thickening, stabilizing, and emulsifying properties. This natural hydrocolloid is crucial for formulators seeking reliable, plant-based rheology modifiers and water-binding agents. It is primarily needed by manufacturers in the food, pharmaceutical, and personal care industries to enhance product texture, stability, and performance.

Application

• Food Industry: Used as a thickener, stabilizer, and emulsifier in dairy products, sauces, dressings, and bakery fillings.
• Pharmaceuticals: Serves as a binder and disintegrant in tablet formulations and as a suspending agent in liquid medications.
• Cosmetics & Personal Care: Functions as a film-forming agent, viscosity modifier, and stabilizer in creams, lotions, hair gels, and denture adhesives.
• Technical Applications: Employed as an adhesive in paper and textile industries and as a binder in water-based paints and coatings.
• Pet Food: Acts as a gelling agent and binder in wet and semi-moist pet food products.

Quality Control

Our Poly-Karaya is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and compliance with relevant industry standards, including Food Chemicals Codex (FCC) and pharmaceutical-grade requirements where applicable. Every shipment is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, viscosity, microbial limits, and other critical parameters, available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture.
