Which of the following is NOT one of the six main ingredients found in nail polish?

The identification of antioxidant as not being one of the six main ingredients in nail polish is grounded in an understanding of nail polish formulation. Nail polish typically consists of key components that serve specific functions to create a durable, aesthetically pleasing coating on the nail.

Resin acts as a film-forming agent that provides the polish with its structure and helps it adhere to the nail. Solvents, on the other hand, are crucial for diluting the polish to the desired consistency and aiding in its application, allowing the polish to spread smoothly. Pigments are responsible for giving nail polish its color, with various compounds used to create a wide variety of shades.

While antioxidants are beneficial in numerous cosmetic and skincare products for their ability to combat oxidative stress and improve product stability, they are not a standard ingredient in nail polish formulations. The primary focus for nail polish is on achieving the right combination of resin, solvent, and pigment to ensure that the product can adequately serve its purpose on the nails.
