Chemical properties and uses of polysorbate 20

Polysorbate-20 will change color or precipitate reaction with a variety of substances, especially phenol, tannic acid, tar and tar substances. It is widely used as an emulsifier for stable oil-in-water pharmaceutical emulsions.

Polysorbate can also be used as a solubilizer for various molded substances, including essential oils and oil-soluble vitamins, and as a wetting agent for oral or non-gastrointestinal suspensions. Polysorbate has been found to help improve the oral bioavailability of drug molecules of p-glycoprotein substrates.

Polysorbate-80 is Tween 80. It is an organic matter, prepared by the reaction of sorbitol anhydride monooleate and ethylene oxide, with peculiar odor, slightly bitter and slightly astringent, warm feeling, non-ionic surfactant, one of the polyoxyethylene sorbitan fatty acid ester series products. It is soluble in water, ethanol, methanol or ethyl acetate and very slightly soluble in mineral oil.

A type of surfactant commonly used in liquid formulations. It is an oil-water emulsifier, which can be used as a stabilizer, diffusion agent, antistatic agent, fiber lubricant, etc. <

What does sorbito-30 of tetraoleate mean.

Hello, it is a pleasure to serve you and give you the following answer: 30 represents the molecular weight of sorbither-30 tetraoleate, which is a very commonly used lubricant that can be used to lubricate various mechanical equipment. Causes of the problem:

1. Due to the large molecular weight of sorbither-30 tetraoleate, it is easy to block the lubrication pipeline during the lubrication process, resulting in poor lubrication effect; 2. Due to the large molecular weight of sorbither-30 tetraoleate, it is easy to aggregate, and coking is easy to occur at high temperature, which affects the lubrication effect; 3. The temperature limit of sorbitol-30 tetraoleate is low, and it is easy to lose its lubricating properties at high temperatures, which affects the lubrication effect. Solution and practice steps: 1. When using sorbit-30 tetraoleate as a lubricant, a suitable lubrication pipeline should be selected to ensure that the lubricating oil is smooth; 2. When using sorbito-30 tetraoleate as a lubricant, the lubrication system should be checked regularly and the sediment should be removed in time; 3. When using sorbito-30 tetraoleate as a lubricant, appropriate lubricating oil should be selected to ensure its lubricating performance at various temperatures; 4. When using sorbito-30 tetraoleate as a lubricant, the temperature of the grease should be checked regularly to ensure that it does not exceed its temperature limit.

Related knowledge: Sorbitan polyether-30 tetraoleate is a complex composed of sorbitol and four different vegetable oleic acids, which has good lubricating properties and can effectively reduce mechanical equipment.

What does sorbito-30 of tetraoleate mean.

Hello, it is a pleasure to serve you and give you the following answer: Polysorbate-30 tetraoleate is a synthetic lubricant, which is composed of polysorbate and tetraoleate, where "30" indicates the percentage of polysorbate, that is, polysorbate accounts for 30 of the total amount. The solution and practice steps of polysorbate-30 tetraoleate are as follows

1.First, polysorbate and tetraoleate are mixed in proportion so that the content of polysorbate in it is 30. 2.

Then, add the mixture to the Alarm Shaker blender and blend until smooth. 3.Finally, pour the mixture into a container and let it sit for a while to allow it to solidify completely.

Personal tip: When mixing lubricants, make sure the proportions are accurate so as not to affect the performance of the lubricant. When stirring, make sure that the stirring time is sufficient to ensure the homogeneity of the mixture.

Finally, when solidifying, make sure that the liquid is left for enough time to ensure the quality of the lubricant.
