Are Crayola and Silly Putty products harmful if ingested?

The Crayola brand has been a trusted name in homes and schools for over 100 years. We have ensured that our products are safe since 1903, when we first began offering crayons.
All Crayola and Silly Putty products have been evaluated by an independent toxicologist and found to contain no known harmful substances in sufficient quantities to be harmful to the human body, even if ingested or inhaled. In addition, Crayola and Silly Putty art materials carry the Art and Creative Materials Institute's (ACMI) APPROVED PRODUCT (AP) seal, which indicates these products meet or exceed specific quality standards. If needed, your doctor may contact us for assistance in obtaining product ingredient information.
It is possible for an individual to have a sensitivity to a particular ingredient, just as one could have a sensitivity to a certain food. All Crayola formulas are compared against a list of common allergens to identify any possible sensitivities.
