CARCINOGENICITY:
NTP...................................................................... Product not listed.
IARC .................................................................... Product not listed.
OSHA................................................................... Product not listed.
Many studies have been conducted to assess the potential carcinogenicity of diglycidyl ether of
bisphenol-A. Although some weak evidence of carcinogenicity has been reported in animals, when all of
the data are considered, the weight of evidence does not show that DGEBPA is carcinogenic. Indeed,
the most recent review of the available data by the International Agency for Research on Cancer (IARC)
has concluded that DGEBPA is not classified as a carcinogen.
Epichlorohydrin, an impurity in this product (<5 ppm) has been reported to produce cancer in laboratory
animals and to produce mutagenic changes in bacteria and cultured human cells. It has been established
by the International Agency for Research on Cancer (IARC) as a probable human carcinogen (Group 2A)
based on the following conclusions: human evidence ?inadequate; animal evidence ?sufficient. It has
been classified as an anticipated human carcinogen by the National Toxicology Program (NTP).
