Although they are attracted to oil, and an oil-in-water emulsion forms, the emulsion will not stay stable for long and will eventually coalesce. [10] With the addition of a polyelectrolyte, electrostatic forces between the oil and water interface are formed and the surfactant begins to act as an “anchor” for the polyelectrolyte, stabilizing ...

In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Solution styrene-butadiene rubber (sSBR) is produced by anionic polymerization in hydrocarbons leading to rubber with better properties for making tires than emulsion polymerization type. Polyvinyl acetate used further for polyvinyl alcohol is manufactured by radical polymerization in methanol solution.
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products.. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone.

starch acetate hydroxypropylated starch cationic starch carboxymethylated starch. An ancient way of modifying starch is malting grain, which humans have done for thousands of years. The plant's own enzymes modify the grain's starches. The effects can be modulated by varying the duration and the ambient conditions of the process.
Carboxymethyl cellulose, along with other emulsifiers, is suggested as a possible cause of inflammation of the gut , through alteration of the human gastrointestinal microbiota, and has been suggested as a triggering factor in inflammatory bowel diseases such as ulcerative colitis and Crohn's disease.

Polyelectrolytes that bear both cationic and anionic repeat groups are called polyampholytes. The competition between the acid-base equilibria of these groups leads to additional complications in their physical behavior. These polymers usually only dissolve when sufficient added salt screens the interactions between oppositely charged segments.
