Potential health effects:

Acute toxicity:

Of moderate toxicity after single ingestion. Virtually nontoxic after a single skin contact. The product has not been fully tested. The statements have been derived in parts from products of a similar structure or composition.

Irritation / corrosion: Not irritating to the skin. Eye contact causes irritation.

Assessment other acute effects: Apart from effects causing lethality, no specific target organ toxicity was observed in experimental studies.

Sensitization: Skin sensitizing effects were not observed in animal studies.

Chronic toxicity: Carcinogenicity: In long-term studies in rats in which the substance was given by feed, a carcinogenic effect was not observed.

Repeated dose toxicity: Repeated oral uptake of the substance did not cause substance-related effects.

Repeated ingestion of large amounts may lead to metabolic acidosis.

Teratogenicity: No indications of a developmental toxic / teratogenic effect were seen in animal studies.

Genotoxicity: In the majority of studies performed with microorganisms and in mammalian cell culture, a mutagenic effect was not found. A mutagenic effect was also not observed in in vivo tests.

Signs and symptoms of overexposure:

Overexposure may cause: vomiting, lethargy, confusion, hyperventilation, nausea, headache

Potential environmental effects

Aquatic toxicity: Acutely harmful for aquatic organisms. The inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.

4: First-Aid Measures
