Which ingredient is commonly used in products to enhance cleansing properties?

Surfactants are commonly used in cleansing products because they have the unique ability to reduce the surface tension of water, allowing it to more effectively penetrate and lift away dirt, oil, and impurities from the skin or hair. This makes them essential ingredients in a wide range of cleansing formulations, from shampoos to body washes. Surfactants work by surrounding and encapsulating dirt and grease, making it easier for water to rinse them away, thereby enhancing the overall effectiveness of the cleansing process.

In contrast, petrolatum primarily acts as a barrier and is more suitable for moisturizing rather than cleansing. Emollients are used to soften and soothe the skin but do not have cleansing properties. Alpha Hydroxy Acids (AHAs) are often used for exfoliation rather than for cleansing, as they work to remove dead skin cells rather than providing a deep clean. Thus, surfactants stand out as the key ingredient for enhancing the cleansing properties of products.
