What is polyglycerol fatty acid ester?

Polyglycerol fatty acid ester (Polyglycerol ester of fatty acid) is a new polyhydroxy ester nonionic surfactant with high efficiency and excellent performance. It is a light yellow powder. Its raw materials mainly include glycerol, glycerol ester and fatty acid. Polyglycerol fatty acid ester has more hydrophilic hydroxyl groups. Its hydrophilicity increases with the increase of glycerol polymerization degree, and its lipophilicity varies with the different fatty acid alkyl groups. Polyglycerol fatty acid ester can be decomposed and used by the human body during human metabolism and is highly safe. At the same time, because it is quite stable in acidic, alkaline, and neutral environments, and has good emulsification when the salt content is high, it can be used as food additives in the food industry. In addition, it can also be used as cosmetics materials for multiple purposes. Because it is colorless, odorless, and not easy to hydrolyze, it has no adverse effects on the appearance and smell of the product. It can also be compounded with other emulsifiers and has a good synergistic effect.

What are the effects?

1. Emulsifying properties: Polyglycerol fatty acid esters have excellent emulsifying properties and can effectively improve the emulsifying properties and stability of products.
2. Stability: Polyglycerol fatty acid esters show good stability under various environmental conditions, such as acidic, alkaline and neutral environments, as well as high salinity environments.
3. Antibacterial ingredients: Some polyglycerol fatty acid esters have antibacterial effects on bacteria, molds, yeasts, etc., and can effectively extend the shelf life of products.
4. Quality improvement: Polyglycerol fatty acid esters can improve the processing performance and final quality of products, such as improving the texture and taste of food, improving the skin feel and stability of cosmetics, etc.

How to use it?

1. Food additives: Polyglycerol fatty acid esters are widely used in the food industry, such as emulsifiers, stabilizers, dispersants, thickeners, defoamers, quality improvers, oil crystallization regulators, etc. for dairy products, vegetable protein beverages, margarine, ice cream, bread, cakes, pastries, biscuits and other foods. It can improve the emulsification and stability of food, improve the texture and taste of food, and extend the shelf life of food.
2. Cosmetics materials: As a moisturizer and emollient in cosmetics, it can form a protective film on the skin surface to lock in moisture and prevent skin dryness. At the same time, it can also help the oil phase and the water phase to mix evenly to form a stable emulsion, improve the skin feel of the product, and make the product easier to apply and absorb.
3. Pharmaceutical raw materials: With its good biocompatibility and safety, it is used as a drug carrier, sustained-release agent and excipient. It can improve the solubility and stability of drugs, promote the absorption and distribution of drugs, and thus improve the therapeutic effect.
