An emulsion is a heterogeneous system consisting of at least one immiscible liquid that is dispersed in another liquid as fine droplets with a diameter of up to 1.5 μm, such systems having low stability by adding materials. Active on the surface, fine solids, etc., this stability is enhanced. A relatively simple classification for emulsifiers is given, which is an optional subdivision and consists of three main groups.
A. Finely divided solids
B- naturally occurring materials
C- surface-active materials
1. It is insoluble in water, soluble in hot oil and organic solvent, and is a highly oleophilic emulsifier.
2. Used for W/O type latex bomb, polyamide fiber and viscose cord oil, with good smoothing effect on fiber.
Lubricant and softener for textile and leather applications.
3. As a film anti-fogging agent, it has good early-stage and low-temperature anti-fogging performance,
