An Overview of Polysorbate 60 and Its Various Uses

Ⅰ. Background and overview of polysorbate 60

Polysorbate 60, lemon to orange oily liquid or semi-gel, slightly special odor, slightly bitter. Polysorbate 60 is a non-ionic surfactant, which has been widely used in food, daily chemical, medicine, mechanical processing and other fields. There are two kinds of synthesis methods: one-step method and two-step method. The products produced by the traditional one-step alkali catalysis method contain various by-products such as diesters and triesters, which are dark in color and unstable in quality. They can only be used for petroleum, washing and textile industries. The two-step method is divided into two types: first etherification followed by esterification and first esterification followed by etherification. The color of the product obtained by first etherification and then esterification is black, the content of diester and triester is high, and the quality and performance are poor; The product obtained by the production process of esterification first and then etherification has darker color, higher hydroxyl value, poor fluidity and transparency in liquid state, but higher monoester yield and good quality performance.

Ⅱ. Multiple Polysorbate 60 uses

Polysorbate 60 is used as an emulsifier, stabilizer (especially for frozen desserts, to avoid oil-water separation), dispersant (such as the dispersion of non-dairy coffee mate), keep bread and donuts moist, and add alcoholic beverages to non-alcoholic beverages. foaming agent.

1. Food industry: Polysorbate 60 has good activity and can improve the human body's ability to absorb liquid paraffin and other fat-soluble substances. It is widely used in the food industry, used as emulsifier for cream, vegetable oil, pastry, coating of candy and cocoa products, emulsifier and defoamer for coffee and beverage, bread fermentation regulator, emulsifier, fortifier, mixed dessert dispersant, semi-fluid beverage wetting agent, colloid for synthesizing sweet pastry, etc.

2. As a wetting agent, Polysorbate 60 is used as an emulsifier in toothpaste, and it is widely used in hair dye cream, body lotion, and sunscreen lotion.

3. In the process of starch sugar fermentation to produce monosodium glutamate, adding Polysorbate 60 can greatly improve the yield and economic benefits of the product; in the cleaning fluid of food machinery and the processing fluid of the metal processing industry, Polysorbate 60 plays a moisturizing role. Wetting, dissolving, dispersing, emulsifying, decontaminating, lubricating, defoaming, brightening, etc.; Polysorbate 60 has been used in synthetic fibers, synthetic plastics, synthetic rubber, medicine, petroleum, etc.
