Application Brief Introduction of polyglycerol fatty acid ester

 

Polyglycerol fatty acid ester (PGFE), abbreviated as polyglycerol ester, is an ester formed from polyglycerol and fatty acid. It is a new type of polyhydroxy ester nonionic surfactant with high efficiency and excellent performance.

 

Use

It is fed simultaneously with other required raw materials, dissolved, stirred, and emulsified at a temperature of about 70°C or higher, and then various products are made according to law.

 

Since it is soluble in grease, it is heated to dissolve with grease, and then fed after mixing.

 

Add one part of PGFE to 3-4 parts of water, heat to 70°C or higher, stir to dissolve, and then cool under stirring to obtain a milky white paste. Put this paste into the raw material for better effect.

 

Suggested dosage: 0.1%-0.5%

 

Storage method and shelf life: Store in a cool and dry place, 18 months.

 

Nature

 

As the polyglycerol ester in the glycerol fatty acid ester series, its emulsification performance is much better than that of monoglyceride. The reason is that polyglycerol ester has more hydrophilic hydroxyl groups; and its hydrophilicity increases with the increase of glycerin polymerization degree. The lipophilicity varies with different fatty acid alkyl groups, so by changing the degree of polyglycerol polymerization, fatty acid type and esterification degree, 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 are suitable for various special purposes.

 

The appearance of polyglycerol esters ranges from light yellow oily liquid to waxy solid, which is related to the combination of different fatty acids. Polyglycerol ester has both hydrophilic and lipophilic properties, and has multiple properties such as good emulsification, dispersion, wetting, stability, and foaming. It can be decomposed in the process of human metabolism, thereby participating in metabolism, and used by the human body. It has a high degree of safety. It is a high-efficiency and safe additive and is recommended by the Food and Agriculture Organization of the United Nations and the World Health Organization (FAO/WHO). At the same time, polyglycerol esters are quite stable in acidic, alkaline and neutral environments, and have good emulsification properties when the salt content is high. Polyglycerol ester is colorless, odorless, hard to hydrolyze, and has no adverse effects on product appearance and odor; it can be compounded with other emulsifiers and has good synergistic effects, so it is widely used in food, daily chemical, petroleum, textile, Coatings, plastics, pesticides, rubber, medicine and other fields. Based on all these application, Polyglycerol esters have become a rapidly developing class of nonionic surfactants.

 

Committed to provide safe, high-quality, innovative and practical raw materials for the food industry at home and abroad. With the expertise and mature technology in the field of emulsifier and the correct grasp of the market, it rises rapidly.
