clastogenic in the chromosomal aberration test.
Carcinogenicity:
This product is not known or reported to be carcinogenic by any reference
source including IARC, OSHA, NTP or EPA. One hundred mice were
exposed dermally 3 times a week for 18 months to a solution of calcium
hypochlorite. Histopathological examination failed to show an increased
incidence of tumors. IARC (International Agency for Research on Cancer)
reviewed studies conducted with several hypochlorite salts. IARC has
classified hypochlorite salts as having inadequate evidence for
carcinogenicity to humans and animals. IARC therefore considers
hypochlorite salts to be not classifiable as to their carcinogenicity to humans
(Group 3 Substance).
CALCIUM CHLORIDE
This chemical is not known or reported to be
carcinogenic by any reference source including IARC,
OSHA, NTP, or EPA.
