There are many products of Twain series, Tween 60, 80 is the main product in the Tween series, today's Shanghai Chain Set Chemical Xiaobian will tell you about the performance and application of Tween 20. Tween 20 can also be called Tween T20, T 20, T-20, etc., its main component is polyoxyethylene dehydrated sorbitol fatty acid ester.
It is a combination of sipan and ethylene oxide, is a non-ionic surfactant, before making Tween we need to make the sipan, Tween 20 has a peculiar smell, warmth, slightly bitter.
Tween appearance is slightly yellow waxy solid to amber oily liquid or paste, t20 is amber viscous liquid, easily soluble in water, methanol, ethanol, isopropanol and other solvents, insoluble in motion, mineral oil, with emulsification, diffusion, solubilization, stability and other properties.
Tween 20 is an amber oily liquid with a special odor and a faint bitter taste. The hydroxyl value is between 90-110, the saponification value is 40 to 50, the acid value is less than or equal to 2, the moisture value is less than or equal to 3, the HLB value is 16.5, the relative density is 1.01, the boiling point > 100 °C, the flash point is 321 °C, the refractive index is 1.472, and the viscosity (25 °C) is 0.25 to 0.40 Pa·s. Tween T-20 can be used as a solubilizer, diffuser, stabilizer, lubricant and antistatic agent.
Tween 20 Applications:
1. This product is harmless to the human body, no irritation, and is mainly used in the food industry for cake, ice cream, shortening and other productions.
2. In other respects, it can be used as an emulsifier for mineral oil, a solvent for dyes, an emulsifier for cosmetics, a stabilizer for foam plastics,
3. In pharmaceuticals as an emulsifier, diffusion agent and stabilizer, as well as as an aid to photo emulsion.
4. In oil extraction, as an anti-wax agent produced by oil wells, it can remove the wax formation of oil wells; as a viscosity reducing agent, it can reduce the viscosity of crude oil flow and improve oil wells. Yield, improve conveying capacity.
5. Used as solubilizer, penitent and dispersant for drugs and cosmetics in medicine and daily chemicals.
6. Because this product has anti-rust and lubricity, it is used to prepare anti-rust lubricating oil and de-rust and degreasing trace oil.
