Description

Polyglycerol Ricinoleate is a non-ionic, biodegradable surfactant and emulsifier derived from castor oil. This versatile compound is valued for its excellent stabilizing and solubilizing properties in complex formulations. It serves as a critical functional ingredient for manufacturers in the food, cosmetics, and pharmaceutical industries seeking natural and effective emulsification solutions.

Application

• Food Industry: Primary emulsifier (E476) in chocolate, margarine, and low-fat spreads to control viscosity and prevent fat bloom.
• Cosmetics & Personal Care: Key emulsifier and stabilizer in creams, lotions, and makeup, providing a smooth texture and enhancing product stability.
• Pharmaceuticals: Used as an excipient in topical ointments and creams for its emulsifying and non-irritating properties.
• Industrial Applications: Acts as a lubricant additive and a plasticizer in certain polymer formulations.
• Bakery & Confectionery: Improves dough handling and aeration, and maintains freshness in baked goods and fillings.
