Which chemical is commonly used to enhance the durability of acrylic nails?

Ethyl Methacrylate is the correct answer because it is a key ingredient in the formulation of acrylic nails. This chemical is a type of monomer that polymerizes to form a durable and strong structure when mixed with a polymer (usually Polymethyl Methacrylate). The resulting acrylic nails offer excellent adhesion to the natural nail and a long-lasting finish that can withstand daily wear and tear.

Using Ethyl Methacrylate enhances the overall integrity and longevity of acrylic nails, making them resistant to chipping and breaking. This property is highly desirable in nail enhancements, as clients often seek durability alongside aesthetic appeal.

In contrast, the other chemicals listed do not serve the same purpose in the context of acrylic nails. Hydrogen Peroxide is primarily used for its bleaching and disinfecting properties, while Formaldehyde is a preservative and antiseptic, not specifically tied to enhancing the strength of acrylic nails. Acetic Acid, on the other hand, is commonly found in vinegar and is not utilized in nail enhancements for durability. It serves different purposes in beauty and skincare, such as balancing pH. Therefore, Ethyl Methacrylate remains the best option for enhancing the durability of acrylic nails.
