Product Application of Polysorbate 20 CAS#9005-64-5

Tween 20 is an oil-in-water emulsifier that can be used as a solubilizer, diffusant, stabilizer, lubricant and antistatic agent. In oil production, it can be used as a paraffin inhibitor to remove wax deposits in oil wells; as a viscosity reducer, it can reduce the viscosity of crude oil flow, increase oil well production, and improve transportation capacity. In medicine and daily chemicals, it is used as a solubilizer, penetrant and dispersant for medicines and cosmetics. Because Tween 20 has rust resistance and lubricity, it is used to prepare rust-proof lubricating oils and rust-removing and greasing oils.
