Company information

Polyglycerol-4, like Polyglycerol-3, is a synthetic polymer formed by the polymerization of **glycerol** molecules. In this case, four glycerol units are linked together through ether bonds, creating a slightly longer chain compared to Polyglycerol-3. This increases its molecular weight and slightly alters its properties. ### Key Uses of Polyglycerol-4: 1. **Emulsifier**: It is effective in stabilizing oil-in-water emulsions, making it useful in food, cosmetics, and personal care products. 2. **Surfactant**: Polyglycerol-4 can reduce surface tension in liquid formulations, improving texture and consistency. 3. **Skin Conditioning Agent**: In cosmetics and skincare, Polyglycerol-4 can act as a humectant, helping retain moisture in the skin, which contributes to hydration and a softer feel. 4. **Thickening Agent**: Due to its polymer structure, Polyglycerol-4 can increase the viscosity of formulations, making them thicker without affecting other properties. Polyglycerol-4 is widely regarded as safe in regulated amounts, and it can often be found in products like creams, lotions, shampoos, and certain food products.
