While "glow in the dark powder" or "UV glow powder" are common terms, phosphorescent pigment is the most accurate and encompassing term.
Different types of phosphorescent pigments exist, including:
* Strontium Aluminate: This is a very bright and long-lasting glow pigment, often used in high-quality glow-in-the-dark products. It requires charging with light to glow and then emits light for many hours after the light source is removed.
* Zinc Sulfide: An older, less expensive option, but not as bright or long-lasting as strontium aluminate.
Make sure the pigment you choose is safe for cosmetic use. Look for pigments that are non-toxic and approved for use in nail products.
