Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- Version / remarks:
- May 12, 1981
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- A valid GPMT conducted according to guideline is available, which is reliable with restrictions and adequate for classification and labelling purposes. Potency estimation is not mandatory when existing guideline and GLP conforming data are available, which were conducted before the new annex of the REACH Regulation entered into force. Moreover, no indication for skin sensitisation was observed in this study, thus, no dose response information is needed. For this reason and for reasons of animal welfare no additional LLNA was conducted.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Polyglyceryl-2 caprinate is not a dermal sensitiser in this GPMT study.
- Executive summary:
In a dermal sensitisation study according to OECD Guideline 406 (1981) with Polyglyceryl-2 caprinate young adult male and female Pirbright-Hartley guinea pigs (10/sex/group) were tested using the GPMT method.
Based on the results of a preliminary study, the test substance was used at 1% dilution for the intradermal induction (no specific findings), undiluted for epicutaneous induction (slight to moderate erythema) and at 5% dilution (no skin irritation) for the challenge exposure.
Clinical signs, body weight and any skin reactions were evaluated 24 h and 48 h after patch removal. There were no effects observed in the control and the treatment group (sensitisation rate = 0%), thus,
Polyglyceryl-2 caprinate is not a dermal sensitiser in this study.
