ABSTRACT:
A metamorphic nail polish capable of color changing from clear to any visible color (violet, red, blue, yellow . . . ) in presence of sunlight or a any ultraviolet radiation source. The nail polish will go back to colorless as soon as it is removed from the sunlight or the UV source. The present nail polish is capable of undergoing multiple reversible changes without altering its physical properties. The active chemical is a photochromic substance such as spiropyrans or spiroxazines molecules. The photochromic compound is added to any clear nail polish to form a composition sensitive to UV radiation. The composition is not toxic and does not cause skin irritation. It may be directly applied on the nail or on top of a previously applied colored enamel.
