What are ingredients that reduce the surface tension of dirt and oils called?

Emollients
Detergents
Moisturizers
Exfoliants

The correct answer is: Detergents

Ingredients that reduce the surface tension of dirt and oils are known as detergents. These ingredients play a crucial role in cleansing products, allowing them to effectively remove impurities from the skin. By lowering surface tension, detergents help to break up and lift away dirt, oil, and makeup, making it easier for water to rinse them away. While emollients are designed to soften and smooth the skin, and moisturizers help to hydrate and maintain skin moisture levels, they do not have the same effect on surface tension as detergents do. Exfoliants, on the other hand, are used to remove dead skin cells from the surface, but they do not specifically target the cleansing action of dissolving dirt and oils. Therefore, detergents are uniquely suited for this purpose, making the identification of these ingredients key for understanding effective cleansing formulations in esthetics.
