Description

Polyglycerine is a versatile class of polyol compounds formed by the polymerization of glycerol, offering a range of hydroxyl functionalities. This property makes it a valuable, non-toxic, and biodegradable building block for numerous industrial applications, prized for its humectant, emulsifying, and solubilizing capabilities. It is essential for manufacturers in the personal care, food, pharmaceutical, and polymer industries seeking sustainable and multifunctional ingredients.

Application

• Personal Care & Cosmetics: Acts as a superior humectant and moisturizer in creams, lotions, and hair care products, improving skin feel and product stability.
• Food Industry: Used as an emulsifier, stabilizer, and humectant in baked goods, confectionery, and beverages (often as polyglycerol esters).
• Pharmaceuticals: Serves as an excipient in drug formulations, functioning as a solvent, plasticizer, or bioavailability enhancer.
• Polymer & Resin Production: A key polyol component in the synthesis of alkyd resins, polyurethanes, and other polymers, contributing to flexibility and cross-linking.
• Industrial Lubricants & Functional Fluids: Employed as a base or additive in synthetic lubricants and metalworking fluids due to its high viscosity index and thermal stability.
• Surfactants & Detergents: The raw material for producing polyglycerol esters and ethers, which are effective, biodegradable nonionic surfactants.
