Question: 1 / 400

Which ingredient is primarily responsible for creating a glossy finish in nail polish?

Formaldehyde

Acetone

Nitrocellulose

Nitrocellulose is primarily responsible for creating a glossy finish in nail polish due to its unique properties as a film-forming agent. When applied, nitrocellulose dries quickly to form a hard, shiny layer on the nails, which contributes to the overall aesthetic and durability of the polish. This ingredient is essential in many formulations, as it provides not only the desired shine but also helps the color adhere to the nail surface.

Formaldehyde is often used in nail products for its strengthening properties, but it does not contribute to a glossy finish. Acetone is primarily a solvent used for removing nail polish and does not play a role in the finish of the polish itself. Ethyl acetate, while also a solvent, is more commonly associated with the application process rather than providing shine. Thus, nitrocellulose stands out as the key ingredient for achieving that glossy look in nail polish formulations.
