What is formed when two or more non-mixable substances are combined with small droplets of a binder?

When two or more non-mixable substances, such as oil and water, are combined with small droplets of a binder, the result is referred to as an emulsion. An emulsion is a stable mixture of these two immiscible liquids, where one liquid is dispersed in the other in the form of tiny droplets. The binder, often referred to as an emulsifying agent, helps to stabilize the mixture and prevent the phases from separating.

Emulsions are commonly seen in various cosmetic formulations, such as creams and lotions, where the active ingredients and oils must remain evenly distributed throughout the product for optimal application and effectiveness. Understanding emulsions is important in esthetics because it is essential for formulating products that deliver desired results on the skin.
