Description

Polyglyceryl-3 Polyricinoleate is a non-ionic, polymeric emulsifier derived from glycerin and castor oil, widely recognized for its excellent stabilizing and texturizing properties. This versatile compound is crucial for creating stable, high-quality emulsions in complex formulations where standard emulsifiers may fail. It is an essential ingredient for manufacturers in the food, cosmetics, and pharmaceutical industries seeking to improve product consistency, shelf life, and sensory characteristics.

Application

• Food Industry: Primarily used as a highly effective emulsifier (E476) in chocolate, compound coatings, and low-fat spreads to control viscosity, prevent fat bloom, and ensure a smooth mouthfeel.
• Cosmetics & Personal Care: Serves as a key emulsifier and stabilizer in creams, lotions, and makeup products, providing enhanced texture and long-term formulation stability.
• Pharmaceuticals: Employed as an excipient in topical ointments, creams, and controlled-release drug delivery systems to stabilize emulsions and suspensions.
• Industrial Applications: Acts as a lubricant additive and plasticizer in various specialty chemical formulations.
• Bakery & Confectionery: Improves the quality of fillings, icings, and whipped toppings by ensuring aeration stability and consistent texture.

Quality Control

Our Polyglyceryl-3 Polyricinoleate is manufactured under strict quality management systems. Each batch is tested to ensure it meets relevant food grade (FCC, EU Directive) and cosmetic-grade specifications. We provide comprehensive Certificates of Analysis (COA) that detail parameters such as acid value, hydroxyl value, and heavy metal content, ensuring compliance with global regulatory standards for safety and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and moisture absorption, which can affect product quality.
