 Sec. 73.1550  Talc.
 
     (a) Identity. (1) The color additive talc is a finely powdered,
 native, hydrous magnesium silicate sometimes containing a small
 proportion of aluminum silicate.
     (2) Color additive mixtures for drug use made with talc may contain
 only those diluents listed in this subpart as safe and suitable for use
 in color additive mixtures for coloring drugs.
     (b) Specifications. Talc shall meet the specifications for talc in
 the United States Pharmacopeia XX (1980) and the following:
 
 Lead (as Pb), not more than 20 parts per million.
 Arsenic (as As), not more than 3 parts per million.
 
 Lead and arsenic shall be determined in the solution obtained by boiling
 10 grams of the talc for 15 minutes in 50 milliliters of 0.5N
 hydrochloric acid.
     (c) Uses and restrictions. Talc may be safely used in amounts
 consistent with good manufacturing practice to color drugs generally.
     (d) Labeling requirements. The label of the color additive and of
 any mixtures prepared therefrom intended solely or in part for coloring
 purposes shall conform to the requirements of Sec. 70.25 of this
 chapter.
     (e) Exemption from certification. Certification of this color
 additive is not necessary for the protection of the public health, and
 therefore batches thereof are exempt from the certification requirements
 of section 721(c) of the act.
