What is the amount of nitrocellulose typically found in top coats compared to nail enamel?

The correct choice indicates that top coats typically contain more nitrocellulose than standard nail enamel. Nitrocellulose serves as a film-forming agent in nail products, providing a durable and glossy finish. Top coats are specifically designed to enhance the longevity and protection of the nail enamel beneath, and to achieve these properties, they often incorporate a higher concentration of nitrocellulose compared to regular nail polish.

The greater amount in top coats helps to create a stronger barrier against chips and scratches, ultimately prolonging the wear of the manicure. Thus, the formulation differences between top coats and nail enamels are fundamental in achieving their respective performance characteristics, making a higher nitrocellulose concentration in top coats essential for their intended use.
