Introduction of polyoxyethylene sorbic monopalmitate.
Polyoxyethylene sorbic monopalmitate, also known as Tween 80, is a non-ionic surfactant widely used in food, cosmetics, medicine and pesticides. This article will introduce the characteristics, production methods, application fields and safety of polyoxyethylene sorbic monopalmitate.
1. Characteristics of polyoxyethylene sorbic monopalmitate.
Polyoxyethylene sorbate monopalmitate is a yellowish to yellow oily liquid with hydrophilic, emulsifying, and dispersing properties. The polyoxyvinyl group in its molecular structure makes it have good water solubility, while sorbitan monopalmitate gives it good emulsifying properties. In addition, polyoxyethylene sorbic monopalmitate has a high chemical stability and is stable over a wide pH range.
2. Production method of polyoxyethylene sorbic anhydride monopalmitate.
The production of polyoxyethylene sorbic anhydride monopalmitate is mainly produced by chemical synthesis methods. The specific steps are as follows: first, sorbitan monopalmitate is reacted with ethylene oxide to generate polyoxyethylene sorbitan monopalmitate. In the production process, it is necessary to strictly control the reaction temperature, pressure and raw material ratio to ensure the stability of product quality and output.
3. Application fields of polyoxyethylene sorbic monopalmitate.
Polyoxyethylene sorbic monopalmitate is widely used in various fields due to its excellent surface activity and emulsifying properties
1.Food industry: used as food additives, such as emulsifiers, stabilizers, thickeners, etc., can improve the taste and appearance of food, improve the quality and stability of food.
2.Cosmetics industry: used as emulsifiers, wetting agents and detergents, etc., can improve the stability and use effect of cosmetics.
3.Pharmaceutical industry: used as pharmaceutical excipients, such as wetting agents, emulsifiers and stabilizers, etc., can improve the solubility and stability of drugs, and improve the bioavailability of drugs.
4.Pesticide industry: used as a pesticide adjuvant, it can improve the dispersion and adhesion of pesticides, and increase the efficacy of pesticides.
5.Other fields: Polyoxyethylene sorbic anhydride monopalmitate can also be used in petroleum, rubber, coatings and other fields, as an emulsifier, wetting agent and dispersant.
Fourth, the safety of polyoxyethylene sorbic anhydride monopalmitate.
Polyoxyethylene sorbic monopalmitate is a food additive whose safety is subject to rigorous evaluation and review. According to relevant regulations and standards, the dosage and scope of use of polyoxyethylene sorbic monopalmitate are clearly defined. At the same time, when consumers use products containing polyoxyethylene sorbic monopalmitate, they should follow the normal usage method and avoid excessive use or abuse.
In short, polyoxyethylene sorbic anhydride monopalmitate, as an important non-ionic surfactant, has a wide range of application fields and good development prospects. In the future, with the continuous progress of science and technology and the expansion of application fields, the application prospect of polyoxyethylene sorbic anhydride monopalmitate will be broader.
