Do Shepherd Color pigments contain heavy metals?
The definition of ‘heavy metal’ varies from company to company, organization to organization, and regulation to regulation. Shepherd CICPs, due to their high calcination temperatures and inorganic crystalline structure, have extremely low bio-availability. In fact, for most products, the LD50 (a measure of non-toxicity) is higher than table salt! Any impurities are present in trace amounts only, less than the levels mandated by most food-contact regulations worldwide.
