Applicant's summary and conclusion

Conclusions:
Vanillin was considered to have no teratogen effects.
Executive summary:

10 female rats per group were exposed one week before mating until 4 days post partum to 0, 125, 250, 500 mg/kg bw/day of Vanillin. Maternal toxicity had been reported with only few details: death, clinical signs and change in body weight and feed consumption. The NOAEL maternal was consider to be 250 mg/kg bw. No effect on pups were reported and the NOEL for teratogenicity was the highest dose tested 500 mg/kg bw.
