Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Under the study conditions, the dermal LD50 was >2000 mg/kg bw (equivalent to 455 mg Zn/kg bw or 1443 mg zinc diacrylate/kg bw).
Executive summary:

Zinc sulphate heptahydrate was administered to the skin of five Wistar rats of each sex at 2000 mg/kg bw for 24 h. Animals were observed for 15 days. Clinical signs of toxicity consisted of erythema (grade 1 and 2, of maximum grade 4), scales and/or scabs (scale 1 and 2, of maximum scale 3) in the treated skin area between observation days 2-8. Zinc sulphate was not harmful or toxic via the dermal route. Under the study conditions, the dermal LD50 was >2000 mg/kg bw (equivalent to 455 mg Zn/kg bw or 1443 mg zinc diacrylate/kg bw) (Van Huygevoort, 1999).
