What is an invert emulsion?

An invert emulsion is characterized by a mixture where water droplets are suspended in oil, which is the defining feature of this type of emulsion. This structure allows for a unique distribution of active ingredients, making it especially useful in various applications, including agricultural and aquatic pest control. Invert emulsions can provide enhanced stability and controlled release of the active substances, improving their effectiveness.

The other options illustrate different types of mixtures: the first describes a standard emulsion with oil in water, the second refers to a soluble herbicide rather than an emulsion type, and the last simply indicates solid particles dispersed in a liquid, which does not convey the specific characteristics of an invert emulsion.
