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 ...
Its stability and relative nontoxicity allows it to be used as a detergent and emulsifier in a number of domestic, scientific, and pharmacological applications. As the name implies, the ethoxylation process leaves the molecule with 20 repeat units of polyethylene glycol ; in practice these are distributed across 4 different chains, leading to a ...
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. [9]
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.
cationic polymerization: An ionic polymerization in which the kinetic-chain carriers are cations. [ 1 ] In polymer chemistry , cationic polymerization is a type of chain growth polymerization in which a cationic initiator transfers charge to a monomer , which then becomes reactive.

In this example, the surfactant molecules' oil-soluble tails project into the oil (blue), while the water-soluble ends remain in contact with the water phase (red). Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids , a liquid and a gas , or a liquid and a solid .
