What property distinguishes an emulsion?

An emulsion is characterized by being an unstable mixture of immiscible substances, typically oil and water. This means that the two liquids do not mix well on their own, leading to a separation over time. To stabilize emulsions, emulsifiers (substances that serve as a bridge between the oil and water) are often used to help keep the mixture consistent and usable for various applications, such as in skincare or cosmetic products.

The essence of an emulsion lies in the nature of its components: the immiscibility of the liquids involved. Emulsions can separate if not properly maintained, which is why they often require special handling or the addition of stabilizing agents. Understanding this property of emulsions is crucial for anyone in the cosmetology field, as it impacts product formulation and effectiveness.
