INCI: Zinc Sulfide CAS# 1314-98-3
NOT ALLOWED IN BATH BOMBS AND WASH OFF PRODUCTS
Our "Glow in the Dark" pigments are approved for cosmetics use. Not all glow pigments activate well and light up. We have chosen 3 so far that activate best. To activate them, expose them to light.
There is only one ingredient that is approved for use in glow pigments for makeup. The color additive luminescent zinc sulfide is zinc sulfide containing a copper activator (copper chloride). The FDA has stringent standards as to how much copper chloride can be in the powder. Glow in the dark zinc sulphide is generally at least 99.8% Zinc Sulphide and less than 0.02% Copper Chloride. It is the copper activator that make the zinc sulphide glow! Here is an example of the breakdown of this pigment. The INCI for luminescent zinc sulphide is INCI: Luminescent Zinc Sulphide.
