Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Glycerol failed to provoke an SI of 3 or more at any test concentration examined, despite
employing relatively high doses of material (maximum concentration 100%) and is thus considered to be non-sensitising.
