Application

Polyoxyethylene (20) Sorbitan Monolaurate is a non-ionic surfactant.It can be used as increasing solvent, diffusing agent, stabilizing agent, antistatic agent, lubricant etc. It is also used as O/W food emulsifier, used alone or mixed with span -60, span -65 and span -80, which has the ability to increase the absorption of liquid paraffin and other fat-soluble substances for humans. In pharmaceutical and daily-use chemical industry, it is usually used as solvent increasing, permeating agent and dispersing agent for drugs and cosmetics. It can remove the wax from oil well as a paraffin inhibitor in oil production, and can reduce the flow viscosity of crude oil to improve oil well production and conveying capacity as a viscosity reducer.
