Which ingredient makes nail polish more flexible and less likely to chip?

Plasticizers are ingredients used in nail polish to enhance its flexibility and durability. By incorporating plasticizers, the formulation allows the polish to bend and move without cracking or chipping, which increases the longevity of the manicure. This flexibility is essential for nail health, especially when hands are frequently in contact with water or when the nails experience pressure or impact.

Formaldehyde, while occasionally used in some formulations, serves a different purpose mainly related to strengthening the polish but does not contribute to flexibility. Color pigments are responsible for the color of the nail polish but do not influence its structural properties. Thickeners are added to improve the viscosity of nail polish but may not enhance its flexibility or reduce chipping. Therefore, plasticizers are the key ingredient that makes nail polish more adaptable and resilient against chipping.
