What materials are classified as "non porous"?

Materials classified as "non-porous" have a surface that does not allow liquids or air to penetrate. This characteristic is essential in the cosmetology field for maintaining hygiene and preventing the growth of bacteria and other pathogens. Non-porous materials can be easily cleaned and disinfected, which is crucial in salons and spas where clients expect a safe and sanitary environment.

Metal, glass, and plastic fall into the non-porous category because they do not absorb fluids or moisture. For instance, stainless steel tools can be sterilized after use, while glass surfaces can be wiped down and disinfected thoroughly. Plastic tools are also designed to resist moisture uptake, making them suitable for repeated use without the risk of contamination.

In contrast, paper and cloth are porous materials that can absorb liquids, making them less ideal for direct contact in a cosmetology setting where sanitation is paramount. Wood, while durable, is often treated as porous because it can absorb moisture and harbor bacteria. Concrete and soil, being constructions of natural and granular materials, are also classified as porous due to their ability to allow airflow and moisture penetration. Therefore, the choice of metal, glass, and plastic as non-porous materials is correct and aligns with industry standards for maintaining hygiene and safety
