E475 – Polyglyceryl ester of fatty acid (PGFE)

Polyglyceryl ester of fatty acid (Polyglycerol ester of fatty acid;PGFE;E475) is the general name of a series of products, aliases polyglyceryl ester (PGFE), polyglyceryl monopoly fatty acid ester, fatty acid polyglycerol ester. Polyglyceryl Stearate,Polyglyceryl  Oleate

Its emulsification performance is much better than that of monoglycerides. The reason is that polyglycerol esters have more hydrophilic hydroxyl groups; and its hydrophilicity increases with the increase of the degree of polymerization of glycerol, and its lipophilicity varies with different fatty acid alkyl groups. By changing the degree of polymerization, fatty acid type and esterification degree of polyglycerol, a series of HLB values ​​(hydrophilic-lipophilic balance) can be obtained from 1 to 20, from lipophilic to hydrophilic polyglycerol ester products with different properties, which are suitable for each Kind of special purpose. 

PGFE Series are a new class of polyhydroxy ester nonionic surfactants with high efficiency and excellent performance, which are used in food, daily chemicals, petroleum, textile, coatings, plastics, pesticides, rubber, medicine and other fields.
