Toxicological data
1, acute toxicity: mice (orally) LDLo: 320 mg/kg
Since the LD50 of table salt is 3,000 mg/kg, BPA The degree of acute toxicity is the same as that of table salt.
Ecological data
It is harmful to water. Do not let this product come into contact with groundwater, waterways and sewage systems. Even a small amount of this product seeping into groundwater will cause harm to drinking water and is toxic to organic substances in the water. Do not discharge material into the environment without government permission.
