What is included in the formulation of nail enamel?

The formulation of nail enamel primarily includes plastic resin, which plays a critical role in providing the coating with strength, durability, and a glossy finish. Plastic resins are polymers that create a film when the enamel is applied and later dries. This film forms a protective barrier over the nail, enhancing both the appearance and longevity of the color.

In contrast, other components listed are either not significant in nail enamel formulations or serve different purposes. For instance, barriers are not a direct component of nail enamel but refer more to protective measures taken during application. Water is typically present in some nail products but is not a defining ingredient in standard nail enamel formulations. Mineral oil is more commonly found in nail treatments or conditioners rather than in the enamel itself. Thus, plastic resin is essential for the creation of a high-quality, long-lasting nail enamel.
