Results and discussion

Applicant's summary and conclusion

Interpretation of results:
sensitising
Remarks:
Migrated information
Conclusions:
The report determined the NOEL for potassium dichromate skin sensitisation. Based on the NOEL and justified uncertainty factors, the acceptable dermal exposure level for chromium in consumer products was calculated. The NOEL was 1 µg Cr/cm2 8Based on EC3=0.058%) and the suggested maximum human exposure limit (S-Rfd) for consumer products was 0.01 µg/cm2 Cr.
Executive summary:

The report of Basketter et al. (2003) determined the NOEL for potassium dichromate skin sensitisation. Based on the NOEL and justified uncertainty factors, the acceptable dermal exposure level for chromium in consumer products was calculated. The NOEL was 1 µg Cr/cm2 and the suggested maximum human exposure limit (S-Rfd) for consumer products was 0.01 µg/cm2 Cr.
