Applicant's summary and conclusion

Conclusions:
The study was considered to be of high quality (reliability Klimisch 2). The substance did not show a high toxicity after a single intraperitoneal injection to mice. The LD50 was identified to be ca. 266 mg/kg bw (corresponding to 100 % Choline chloride).
Executive summary:

The acute toxicity of Choline chloride after intraperitoneal injection was investigated in mice (BASF, 1963). The mice received doses of ca. 0.35 mL of a 70 % Choline chloride solution (applied as a 8 % solution in water). No mortality was reported. The main clinical symptoms of intoxications were restlessness, staggering, cramps and laboured respiration. The intraperitoneal toxicity with an approximative LD50 of ca. 266 mg/kg bw of 100 % Choline chloride was found.
