All the color-changing pigments sold by this company do not contain toxic heavy metal components such as mercury, lead, chromium, etc., and are non-toxic and non-irritating to human skin. However, due to their extremely fine particles, when they form dust in the air, they can easily enter the human lungs through the respiratory tract and deposit or enter the blood circulation system, causing adverse consequences. Therefore, during operation, dust masks, rubber gloves and goggles should be worn. If the color-changing pigments accidentally enter the eyes or mouth, they should be immediately rinsed with a large amount of clean water to prevent them from entering the body.

According to relevant national regulations, color-changing pigments, like ordinary pigments, for the parts of their products that contain pigments, direct contact with food and drinking water should be avoided. If used to produce temperature-indicating color-changing plastic dining utensils, a double-layer injection molding process can be adopted, and the color-changing layer should be located in the part that does not come into contact with food.

Thermochromic pigments are non-flammable substances and will not spontaneously combust when heated to 170°C in the air. However, due to their extremely fine particles and huge specific surface area, once they form dust in the air and reach a certain concentration, they may cause deflagration in the presence of an open flame. Please be extremely cautious in operation.
