(e) The chemical additive shall have been tested using the following additional safety tests if not already done by the U.S. Food and Drug Administration.
(1) The chemical additive shall have been tested for safety using worst-case conditions for any contaminants allowed by specifications with a safety factor to cover all ranges of unrestricted consumption.
(2) If the chemical additive, in combination with body minerals, becomes a thermoluminescent phosphor material, which is known to become electrically charged when exposed to radiation and X-rays, testing shall have been done to determine any adverse effects. Thermoluminescent phosphor material examples are calcium fluoride, lithium fluoride, lithium bromide, and calcium sulphate.
