Toxicological data

1, acute toxicity: Mouse (subcutaneous) LD50: 15mg/kg;
Rat (subcutaneous)LD50 70mg/kg

Since the LD50 of table salt is 3,000 mg/kg, BPA has the same degree of acute toxicity as table salt.

Ecological data

If it is slightly harmful to water, do not Allow undiluted or large amounts of product to come into contact with groundwater, waterways or sewage systems. Do not release material into the environment without government permission.
