What does "nonporous" describe?

The term "nonporous" refers specifically to materials that do not allow liquids to be absorbed. This characteristic is essential in various settings, including esthetics, where sanitation and hygiene are critical. Nonporous materials create a barrier that prevents water and other liquids from penetrating, thereby minimizing the risk of contamination and facilitating easier cleaning.

In esthetic practice, tools and surfaces that are nonporous can help ensure that products used on clients do not harbor bacteria or other pathogens, which could lead to skin irritations or infections. This makes nonporous materials ideal for use in treatments and services that require a high standard of safety and cleanliness.

In contrast, the other choices describe materials that do allow for liquid absorption, are easier to clean, or are environmentally degradable, which does not align with the definition of "nonporous."
