Skin Irritation:
This material is expected to be mildly to moderately irritating.
Eye Irritation:
This material is expected to be moderately to severely irritating.
Skin Sensitization:
This material is not known or reported to be a skin or respiratory sensitizer.
Acute Toxicity:
Contact with the eyes and mucous membranes causes transient irritation. Minor
corneal involvement may occur if product is not rinsed immediately from the eyes.
Inhalation may cause irritation. Contact with skin causes irritation.
Subchronic / Chronic
Toxicity:
Damage to lungs has been observed in laboratory animals from repeated
inhalation of high concentrations (70 mg/m3). This damage is characterized by
thickening of the walls of the air sacs and a low grade of pulmonary inflammation.
The risk to human health is low due to the high concentration required to produce
the effect., Repeated or prolonged skin contact with this product may cause
dermatitis and blistering.
Sodium carbonate
Male rats were exposed to an aerosol of 2% aqueous
solution of this chemical, 4 hr.day, 5 days/week for 3-1/2
months. No effect was observed at a concentration of
10 or 20 mg/cubic meter. At 70 mg/cubic meter weight
gain was decreased and the lungs showed thickening of
the intra-alveolar walls, hyperemia, and lymphoid
infiltration., Repeated or prolonged skin contact with this
product may cause dermatitis and blistering.
Reproductive and
Developmental Toxicity:
This chemical has been tested in laboratory animals and no evidence of
teratogenicity was seen.
Sodium carbonate
This chemical has been tested in laboratory animals
and no evidence of teratogenicity was seen.
Mutagenicity:
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.
Sodium carbonate
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.
