Tensides have a water-receptive (hydrophilic) and a water-repellent (hydrophobic) component. The graphic shows how tensides make it possible to dissolve dirt particles in water.

Information and ideas:
Tensides play a role in the production of emulsions. For this reason, they can also be referred to as emulsifiers. They can reduce the tension at the boundary surface between two liquids that do not readily mix, such as oil and water, so that the two substances mix.
