irritation to mucous membranes and respiratory tract.The dry material is irritating to
the skin. However when wet, it will produce burns to the skin.
Subchronic / Chronic
Toxicity:
There are no known or reported effects from repeated exposure except those
secondary to burns.
Reproductive and
Developmental Toxicity:
Calcium hypochlorite has been tested for teratogenicity in laboratory
animals. Results of this study have shown that calcium hypochlorite is not a
teratogen.
CALCIUM CHLORIDE
Not known or reported to cause reproductive or
developmental toxicity.
Mutagenicity:
Calcium hypochlorite has been tested in the Dominant lethal assay in male
mice, and it did not induce a dominant lethal response. Calcium hypochlorite
has been reported to produce mutagenic activity in two in vitro assays. It
has, however, been shown to lack the capability to produce mutations in
animals based on results from the micronucleus assay. In vitro assays
frequently are inappropriate to judge the mutagenic potential of bactericidal
chemicals due to a high degree of cellular toxicity. The concentration which
produces mutations in these in vitro assays is significantly greater than the
concentrations used for disinfection. Based on high cellular toxicity in in vitro
assays and the lack of mutagenicity in animals, the risk of genetic damage
to humans is judged not significant.
CALCIUM CHLORIDE
This product was determined to be non-mutagenic in
the Ames assay. It was also shown to be non-
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.
