Polyglycerol fatty acid esters JS PGIS-21 and JS PGIS-22

1   What is polyglycerol fatty acid ester

Polyglycerol fatty acid ester（Polyglycerol Fatty Ester, abbreviated as polyglycerol ester,PGFE）It is a new, efficient, and high-performance class of polyhydroxy ester non-ionic surfactants obtained by the esterification reaction of glycerol dehydration and condensation with fatty acids. Its synthetic raw materials are derived from natural plant oils and belong to renewable resources. It has high safety, good degradability, and is environmentally friendly. Polyglycerides are becoming the new favorite of the market due to their unique advantages, and are known as the green stars of modern industry.

By selecting different degrees of glycerol polymerization, types of fatty acids, and esterification degrees, various performance polyglycerol ester products ranging from lipophilic to hydrophilic can be obtained,HLBIt has a wide range of values and is suitable for the formulation of water in oil cream, lotion, foundation make-up, lipstick and other products. The higher the degree of polymerization of glycerol, the better its hydrophilicity. The lipophilicity depends on the type and quantity of fatty acids, which can be short chain fatty acids（C≤6）Medium chain fatty acids（6≤C≤12）Long chain fatty acids（C≥12）. At the same time, the degree of unsaturation of fatty acid chains can affect the color and odor of polyglycerol ester products.

II   The use of polyglycerol fatty acid esters

Polyglycerin emulsifiers can significantly improve long-term moisturizing performance, and are only proportional to the degree and concentration of glycerol polymerization.

Polyglycerides can form a stable liquid crystal state, and the emulsion system provides a more moisturizing, gentle, and makeup removing effect on the skin.

Mainly used as a water in oil type（W/O）Emulsifier can emulsify more water phase with less oil phase. It is suitable for the formulation of water in oil cream, lotion, foundation make-up and other products. The oil in water product prepared with it feels oily on the skin without being greasy. Compared with non-ionic polyoxyethylene surfactants, it exhibits excellent oxidation stability and acid-base stability. Compared with sucrose, glycerol, sorbitol esters, etc., it has excellent thermal stability.

Dispersants are often added to makeup products to improve the dispersion of the powder. Dispersants need to have good wetting properties, facilitate the dispersion process, and be able to form stable dispersion systems. Some lowHLBThe polyglycerol fatty acid ester (PGFA) with a value of 0 has good dispersibility and stability for toner and inorganic powder, and is very suitable for water in oil foundation cream, foundation make-up honey, physical sunscreen formula, etc.

Polyglycerol esterHLBThe value distribution is relatively wide. lowHLBValue can be used as defoamer andW/OEmulsifier, highHLBValue can be madeO/WEmulsifier. According to the different properties of different fatty acid chains, they have various effects in cosmetics such as solubilization, foaming, emulsification, moisturizing, and nourishing; Free of epoxy groups, sourced from plant-based raw materials, green and safe, non irritating to the skin, suitable for producing baby skincare products.
