Administrative data

Endpoint:
skin sensitisation: in vivo (non-LLNA)
Remarks:
in vivo
Type of information:
other: handbook
Adequacy of study:
weight of evidence
Study period:
Published in 1985
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The comparative assessment of two sensitisation methods includes limited results for hexyl acetate but is sufficient to support a conclusion that the substance is not a skin sensitiser.

Applicant's summary and conclusion

Interpretation of results:
not sensitising
Remarks:
Migrated information Criteria used for interpretation of results: expert judgment
Conclusions:
Complementary testing of phenyl ethyl acetate in two guinea pig models, one with and one without adjuvant, indicate the absence of sensitising potential.
Executive summary:

No evidence of skin sensitisation was seen with phenyl ethyl acetate, either in the Freund's Complete Adjuvant Test (FCAT: an adjuvant method) or in the Open Epicutaneous Test (OET: a non-adjuvant method). Although the studies are of non-standard design, the constently negative results are considered to be sufficient to conclude an absence of sensitising potential.
