XI- TOXICOLOGICAL INFORMATION
Animal Toxicology:
Acute Toxicity:
Inhalation LC50: Approximately 1300 mg/cubic-meter (1 hr., rat) 鈥? based on
acute inhalation toxicity for chlorine.
Oral LD50: 850 mg/kg. (rat)
Dermal LD50: >2 g/kg. (rabbit)
Causes burns to eyes and skin
Chronic Toxicity: There are no known or reported effects from repeated exposure.
Target Organ Toxicity:
Reproductive and Development Toxicity: Calcium Hypochlorite has been tested for
6
Teratogenicity in laboratory animals. Results of this study have shown that
calcium Hypochlorite is not a teratogen.
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.
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.
