Applicant's summary and conclusion
- Conclusions:
- For benzoic acid reproductive toxicity was assessed in a non-guideline 3-generation study performed in rats with 0, 0.5 and 1% benzoic acid added to the diet, corresponding to approximate doses of 0, 250 and 500 mg/kg bw/d. These doses failed to produce detectable toxic effects on parental and offspring generations or reproductive capacity (ECHA/RAC 2012).
- Executive summary:
For benzoic acid reproductive toxicity was assessed in a non-guideline 3-generation study performed in rats with 0, 0.5 and 1% benzoic acid added to the diet, corresponding to approximate doses of 0, 250 and 500 mg/kg bw/d. These doses failed to produce detectable toxic effects on parental and offspring generations or reproductive capacity (ECHA/RAC 2012).
