About Polyoxyethylene(20)sorbitan monooleate: 

Wettability: polyoxyethylene sorbitan oleate (20) has good wettability, which can reduce the droplet's surface tension and promote the spread and penetration of the liquid on the solid surface. This property makes it widely used in cosmetics, coatings, inks and other industries to improve the wettability and permeability of products.

Dispersion properties: polyoxyethylene sorbitan oleate (20) has good dispersion properties, which can disperse solid particles or pigments in the liquid to form a uniform and stable dispersion liquid. In preparing high-viscosity liquids, suspensions, and pigment pulp products, adding polyoxyethylene sorbitan oleate (20) can effectively prevent the sedimentation and aggregation of solid particles and maintain the stability of the dispersion system.

Solubilizing properties: polyoxyethylene sorbitan oleate (20) can dissolve some substances that are difficult to dissolve in water, thereby improving its solubility and stability in solution. 

Physiological safety: Polyoxyethylene sorbitan oleate (20) is non-toxic and harmless to the human body at the appropriate concentration and is suitable for sensitive fields such as cosmetics, food, and drugs. However, there are also certain safety risks if excessive use or long-term exposure. Therefore, the amount and conditions of use should be strictly controlled during use.

Compatibility: Polyoxyethylene sorbitan oleate (20) is compatible with other surfactants and can work synergically to achieve better performance. Combining with anionic, cationic and non-ionic surfactants, the product's performance can be adjusted to meet the specific application needs.

Temperature and electrolyte sensitivity: Polyoxyethylene sorbitan oleate (20) is sensitive to temperature and electrolyte. Under high temperature or high electrolyte concentration conditions, the surface activity will be reduced. Therefore, excessive heating or an environment with high electrolyte concentration should be avoided during use to ensure the stability of its performance.

Cosmetics: Polyoxyethylene sorbitan oleate (20) is widely used in cosmetics as an emulsifier, wetting agent and dispersant. It can improve product stability, wettability and permeability, making cosmetics easier to apply and absorb. Mainly used in face cream, lotion, toner, makeup, and other products, it can improve skin texture, increase skin moisture, improve skin feeling, and enhance the use effect of products.

Food industry: Polyoxyethylene sorbitan oleate (20) is often used as an emulsifier, stabilizer and thickener in the food industry. Mainly used in yogurt, cheese, ice cream, beverages con, condiments, and other products, it can also be used in bread, pastries, and other food improvers.

Pharmaceutical field: Polyoxyethylene sorbitan oleate (20) is often used as drug excipients or additives in the pharmaceutical industry, contributing to drug preparation and quality control. It can be used as an emulsifier, thickener, and stabilizer in drug suspensions, emulsions, and injections to help improve the efficacy of drugs and reduce the incidence of adverse reactions.

Industrial field: Polyoxyethylene sorbitan oleate (20) is also widely used in the industrial field. It can be used as an ingredient in products such as detergents, cleaners and degreasing agents for cleaning various surfaces and removing oil stains. Through its excellent emulsification, dispersion, and wettability, it can effectively clean various equipment and surfaces and is widely used in petroleum, chemical, mechanical, and electronic industries.

Other fields: Polyoxyethylene sorbitan oleate (20) can also be used as an additive in ink, coatings, adhesives and other fields to help improve product performance and stability. In agriculture, it can be used as a synergist of pesticides to improve the adhesion and efficacy of pesticides. In addition, in environmental protection, it can be used to treat waste oil and wastewater to reduce the toxicity of pollutants.

Production Method of Polyoxyethylene(20)sorbitan monooleate:

Esterification: Esterification is the traditional method for producing polyoxyethylene sorbitan oleate (20). The method is to esterify long-chain alcohol and oleic acid under the action of a catalyst to produce the corresponding oleic acid ester. Then, polyoxyethylene sorbitan oleate (20) with different polymerization degrees was obtained through refining and polymerization. 

Transesterification: Transesterification is a relatively new method for producing polyoxyethylene sorbitan oleate (20). Transesterification can reduce the production of wastewater and waste gas and improve the degree of polymerization of products. Still, it needs to use products with low polymerization as raw materials, which increases the production cost.

Oxyethylene process: The oxyethylene process directly synthesizes the polyoxyethylene sorbitan oleate (20) method. The oxyethylene process has the advantages of simplicity, high product purity, and good environmental protection. Still, it requires high-purity raw materials and special catalysts, which increases the production cost.

Other methods: These methods were carried out under different process conditions and specific raw material conditions, and polyoxyethylene sorbitan oleate (20) with different polymerization degrees and performance indices could be obtained.

No matter which method is used to produce polyoxyethylene sorbitan oleate (20), it is necessary to control the purity of the raw material, reaction temperature, pressure, type and amount of catalyst and other process parameters to ensure the quality and stability of the product.
