Dispersing agent

Dirt and impurities can gather on surfaces and fibres. Cleaning with liquids dissolves dirt particles and deposits from fibres. Dispersing agents are used to ensure that they do not build up again.

Whilst emulsions are a fine mixture of two immiscible liquids, such as oil and water, a suspension is a stable mixture of very small solids in a liquid. This could be, for example, dissolved dirt particles in cleaning processes, or pigment in paint and varnish. The dispersing properties of phosphates support the cleaning action of washing and cleaning products by removing and suspending the solid and insoluble particles from the surface that is being treated.
