As a supplier of glow in the dark pigment, we often encounter customers who request FDA or EN71-3 certificates for glow in the dark pigment. Particularly for customers in the food and toy industries, ensuring the safety and compliance of their products is crucial. Therefore, they typically require glow in the dark pigment to meet relevant standards such as FDA (U.S. Food and Drug Administration) or EN71-3 (European Toy Safety Standard) etc. Obtaining these certificates ensures that the product does not pose any risk to human health when it contacts with food or is used by children.

Why can’t glow in the dark pigment be tested directly?

That’s because glow in the dark pigment will be completely destroyed when in contact with strong acids and alkalis. In this type of food grade or food contacting testing, it will simulate the gastric environment by placing the test substance in a strong acid solution for 1.5-2 hours and observe if any harmful substances dissolve. Under these conditions, the glow in the dark pigment is already destroyed. Therefore, it is meaningless and infeasible to directly use glow in the dark pigment for testing. It must be mixed with a medium and tested by semi-finished or finished products. For example, when applied to plastic products, glow in the dark pigment can be mixed with plastic to make glow in the dark masterbatch for raw material testing. If printing, it can be mixed with ink to make glow in the dark ink to test.

In terms of the application of glow in the dark pigment, some well-known brands such as Starbucks and LEGO have already adopted glow in the dark pigment to enhance the appeal and creativity of their products. Starbucks mix glow in the dark pigment with ink and print logo on the cups. They also create glow in the dark plastic cups and straws. LEGO has applied this pigment in the toys. They launched toy trains. These successful cases fully demonstrate the potential and safety of glow in the dark pigment in the food and toy industries.

We hope that the above explanation clearly illustrates why glow in the dark pigment cannot be directly used for testing, and guides you how to test glow in the dark materials.
