![]() With Zinc Sulfide you are meant to contact a professional waste disposal service ( source). ![]() You will generally see a warning on disposal for anything with a concentrated earth metal in it. ( source) The latest info I could find said that this is the only glow-in-the-dark pigment allowed for cosmetic use.īut when used on external projects, the primary risk of Zinc Sulfide is in inhaling the dust or to the environment during disposal. When applied to the skin there is a higher level of caution due to the possibility of absorption over time. However, facial makeup preparations containing luminescent Zinc Sulfide are intended for use only on limited, infrequent occasions like Halloween, and not for daily use. Zinc Sulfide doped with Copper Chloride is approved by the FDA for cosmetics with some restrictions but is not considered toxic or hazardous. Silver produces blue, Manganese produces orange-red, and Copper produces green. Different metals are used to activate Zinc Sulfide to produce different-colored pigments and paints. Zinc Sulfide is the main form of Zinc found in nature. ![]() I really wanted to understand these phosphorescent metals to make sure they were something I would actually feel safe using. Safety of Phosphorescent Pigmentsīefore looking at some examples of non-toxic paint brands and pigments brands let’s take a closer look at the toxicity issues with these pigments. Upon purchase, I make a small commission at no extra cost to you. While water-based acrylic arts and crafts paints are not high in VOCs, I do provide options on how you can mix the pigments with a zero-VOC paint base. But paints made for arts and crafts do not have to declare their VOC level the way that wall paints do. I also look at the paint base itself, and we always aim for zero-VOCs in a paint. Normal use of these pigments in paints used in arts, crafts, and decor is considered safe, but we are going to look at what that means exactly. Like most metals, you want to be careful not to inhale the powder form, and you don’t want to ingest it. While both types are based on earth metals, neither is considered toxic with normal use. Blue tones have the longest glow time, and green produces a brighter glow. The color of Strontium pigments can vary between various shades of green and blue. The glow also lasts ten times longer, usually for several hours, but it can go on for longer. The newer type of glow-in-the-dark pigment is Strontium Aluminate doped with Europium which is about ten times brighter than Zinc Sulfide. This is the older type of pigment and it’s the least bright type. This is used primarily for products in the novelty category and the less expensive products for kids. Zinc Sulfide-based products are the original glow-in-the-dark pigment. What are glow-in-the-dark paints made of? I take a close look at what these pigments powders are and if they are really non-toxic and safe. This article focuses on glow-in-the-dark paints used on walls, crafts, art projects, and decor items. It is made from phosphors such as Zinc Sulfide (doped with other metals to get different colors) or Strontium Aluminate (doped with Europium or Dysprosium) and typically glows a yellowish-green or blue color. Phosphorescent paint is commonly called “glow-in-the-dark” paint.
