Polysorbate (Polysorbate) is a non-ionic surfactant, which is widely used in the field of chemical production raw materials. It has excellent emulsifying, dispersing, wetting and stabilizing properties, so it is often used as an emulsifier, dispersant, stabilizer, etc. The properties and uses of polysorbate will be described in detail in this paper.
1. Properties of Polysorbates
1. Chemical Structure
Polysorbates are made from sorbitol and ethoxylated fatty acid esters by ethoxylation. Its molecular structure contains many hydrophilic groups and lipophilic groups, which makes it have good surface activity.
2. Emulsifying
polysorbate has excellent emulsifying properties and can effectively emulsify the oil phase and the aqueous phase to form a stable emulsion. Its emulsifying ability increases with the increase of ethoxy content in the molecule.
3. Dispersibility
polysorbate has good dispersibility and can uniformly disperse solid particles in liquid to form a stable suspension.
4. wettability
polysorbate can reduce the surface tension of the liquid, improve the wettability of the liquid, and make the liquid easier to spread on the solid surface.
5. Stability
polysorbate has good thermal stability and acid-base stability, and can be used in a wide pH range.
2. the use of polysorbate
1. food industry
polysorbate in the food industry are often used as emulsifiers and stabilizers for the production of dairy products, ice cream, bread, pastries and other foods. It can improve the taste and appearance of food and extend the shelf life of food.
2. Pharmaceutical Industry
Polysorbates are commonly used as drug carriers and solubilizers in the pharmaceutical industry to improve the solubility and bioavailability of drugs. At the same time, it can also be used as an excipient for preparations such as injections and eye drops to improve the stability of the preparation.
3.
polysorbate in the daily chemical industry is often used as detergent, cosmetics emulsifier and dispersant, used to improve product stability and use effect.
4. Other fields
In addition to the above fields, polysorbate can also be used in textile, printing and dyeing, paper and other industries, as emulsifiers, dispersants and wetting agents.
In conclusion, as an excellent surfactant, polysorbate has broad application prospects in the field of chemical production raw materials.
