Talc

The Food and Drug Administration (FDA) has reviewed the safety of Talc, also known as magnesium silicate, and determined that is it Generally Recognized As Safe (GRAS) for use in food as an anticaking agent. It is also on the list of GRAS substances for use in cotton and cotton fabrics and paper and paperboard used for food packating. Talc is permitted as an indirect food additive as a colorant in polymers, and as a colorant in drugs. The FDA also allows Talc to be used as an inactive ingredient in pharmaceutical products.FDA: Link to Code of Federal Regulations for magnesium silicate and Talc

The European Cosmetics Directive allows Talc to be used in cosmetic products and requires a caution statement to ensure safe use for children under three years of age to address potential over-inhalation (see Annex III).

The Joint FAO/WHO Expert Committee on Food Additives has determined that it is not necessary to establish a limit for the acceptable daily intake of Talc in food. http://www.inchem.org/documents/jecfa/jecmono/v05je04.htm
