-

Please note that by being listed below, no inference should be made about the legality of using any one of these specific substances as an "indirect" food additive. Their presence on this list only indicates that the names of these substances are found (or, in the case of some of the polymers, are implied) in 21CFR parts 175 - 178. The regulation(s) cited for a substance should always be consulted for the complete context before any conclusion is made as to allowed regulated use. To access the specific regulations listed below, type in the title number, 21, and then the section and part numbers, e.g. 175 and 105 at the Government Printing Office web site.

Definitions of the labels that are found in this inventory are:

LabelDefinition
DOCNUMThe PAFA database number
MAINTERMThe name of the substance as recognized by CFSAN
CAS RN OR OTHER CODEChemical Abstract Service (CAS) Registry Number for the substance or a numerical code assigned by CFSAN to those substances that do not have a CAS Registry Number (888nnnnnn or 977nnnnnn-series)
REGNUMRegulation numbers in Title 21 of the U.S. Code of Federal Regulations where the substance appears. (Note that if a substance is mentioned in 21CFR parts 175 - 178 and, thus, is listed below, any other citations for the same substance in other sections of 21CFR dealing with food additives (parts 1 - 199 inclusive) are also cited.)
