USE OF PRESERVATIVE "STAYPRO (WS-7)" IN MALT BEVERAGES.
Brewers and others concerned:
Purpose. This Industry Circular is issued for
the purpose of notifying brewers of the labeling
requirements for malt beverages which contain the
preservative "Staypro (WS-7)".
Chemical Definition. "Staypro (WS-7)" is the
n-heptyl (or n-octyl) ester of para-hydroxy benzoic
acid and its use as a preservative in malt beverages
has been approved by the Food and Drug Administration.
Labeling. As malt beverages are considered
foods under the laws of the Food and Drug Administration
and as that agency requires labels on foods to show
the use of preservatives, the disclosure of the presence
of "Staypro (WS-7)" would be required on the labels of
malt beverages containing such substance.
Inquiries. Correspondence in regard to this
Industry Circular should refer to its number and be
addressed to the Director, Alcohol and Tobacco Tax
Division (CP:AT:B), Washington, D.C., 20224.
