Hydrocarbon-based surfactants are an example group of amphiphilic compounds. Their polar region can be either ionic , or non-ionic. Some typical members of this group are: sodium dodecyl sulfate ( anionic ), benzalkonium chloride ( cationic ), cocamidopropyl betaine ( zwitterionic ), and 1-octanol (long-chain alcohol, non-ionic).
The thickness of a polyelectrolyte then affects its adsorption ability. [1] For more information on polyelectrolyte adsorption, look here. Some examples of polyelectrolytes can be found in the table below. The properties of the polymers vary with molecular weight and degree of polymerization. [2]
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.

The number following the 'polysorbate' part is related to the type of major fatty acid associated with the molecule. Monolaurate is indicated by 20, monopalmitate is indicated by 40, monostearate by 60, and monooleate by 80.
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 ...
This will act as the emulsifier. Then, add six tablespoons of red wine vinegar (or white wine or sherry vinegar). The typical ratio of vinegar to oil is one part acid to three parts oil, however ...
Different polymers are distinguished by the numerical value that follows the word "polyquaternium". Polyquaternium-5, polyquaternium-7, and polyquaternium-47 are three examples, each a chemically different type of polymer. The numbers are assigned in the order in which they are registered rather than because of their chemical structure.
