What is an oil-based material suspended in water known as?

An oil-based material suspended in water is referred to as an emulsion. This term specifically describes a mixture where tiny droplets of one liquid (in this case, oil) are dispersed throughout another liquid (water) in a stable form. In emulsions, the oil and water do not naturally mix, so stabilizers or emulsifiers are often added to maintain this mixture.

Emulsions are crucial in various applications, including pest control, where they can help deliver active ingredients effectively. By ensuring even distribution of oil-based components in a water-based solution, emulsions enhance the efficacy of pest control products.

Other terms, such as solution, suspension, and concentration, refer to different types of mixtures. A solution is a homogeneous mixture where solutes are dissolved in solvents, while a suspension consists of larger particles that may settle over time. Concentration refers to the amount of a substance in a given volume of solution, which does not define the specific type of mixture being described.
