Polyglycerol esters of fatty acids(PGE) is a polyglycerol ester. It is a new type of high-performance, high-performance polyhydroxy ester nonionic surfactant.
Usage: It is simultaneously charged with other raw materials, dissolved, stirred, and emulsified at a temperature of about 70°C or higher, and then various products are prepared according to law.Since it is soluble in fats and oils, it is heated and dissolved with oil and fat, and then mixed and then feed. A part of PGE is added to 3-4 parts of water, heated to 70 ° C or higher, stirred until dissolved, and then cooled under stirring to obtain a milky white paste, and the paste is put into the raw material, and the effect is better.
Recommended dosage: 0.1%-0.5%
Storage method and shelf life: Place in a cool dry place for 12 months.
As a polyglycerol esters in the glycerin fatty acid ester series, its emulsifying property is much superior to that of monoglyceride, because the polyglycerol ester has more hydrophilic hydroxyl groups; and its hydrophilicity increases as the degree of polymerization of glycerol increases. The lipophilicity varies with the fatty acid alkyl group. Therefore, by changing the degree of polymerization of polyglycerol, the type of fatty acid and the degree of esterification, a series of HLB values (hydrophilic-lipophilic balance) can be obtained from 1 to 20, from lipophilic to hydrophilic. Different properties of polyglycerol ester products for a variety of special applications.
The polyglyceride looks from a pale yellow oily liquid to a waxy solid which is associated with its bound fatty acid. Polyglycerol ester has both hydrophilic and lipophilic properties, and has many properties such as good emulsification, dispersion, wetting, stability, and foaming. It is decomposed in the metabolism of the human body, participates in metabolism, is utilized by the human body, is highly safe, and is a kind of high-efficiency safety additive recommended by the Food and Agriculture Organization of the United Nations and the World Health Organization (FAO).
At the same time, polyglycerol esters are quite stable in acidic, alkaline and neutral environments, and also have good emulsifying properties when the salt content is high. Polyglycerol ester is colorless, odorless, and is not easy to be hydrolyzed. It has no adverse effect on product appearance and odor. It can be compounded with other emulsifiers and has good synergistic effect. Therefore, it is widely used in food, daily chemical, petroleum, textile, Coatings, plastics, pesticides, rubber, medicine and other fields. Polyglycerol esters have become a rapidly growing class of nonionic surfactants.
