What makes the candle glow?
Europium and dysprosium doped strontium aluminate is the latest generation of glow producing products. It glows longer and brighter than all previous types. Strontium aluminate (SrAl2O4) is activated with a suitable dopant (such as europium or dysprosium) and it becomes photoluminescent.
Is strontium aluminate safe to use in a candle?
Not only is it safe, it is ECO-friendly, odorless, non-flammable, non-toxic, non-radioactive, and contains no phosphates, formaldehyde, lead, or any other hazardous chemicals. It is inert and contains no heavy metals. The EPA has deemed it safe for humans and the environment. OSHA has no safety recommendations. The USDOT does not classify it as a hazardous material (HAZMAT) for transportation.(1), and it didn’t even make the CA prop 65 list! (2).
