Toxicological data

1. Acute toxicity: Rat (oral) LD50: 200 mg/kg; Rat (subcutaneous) LD50: 160 mg/kg Mouse (subcutaneous) LD50: 64 mg/kg Mouse (intravenous) LD50: 39 mg/kg Guinea pig (on skin)LD50: 500 mg/kg

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