Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Pentaerythritol, reaction product with fatty acids, C8 to 18 (even numbered) and/or branched and/or unsaturated does not have to be classified and has no obligatory labelling requirement for skin irritation according to CLP, however it is classified according to DSD with R38, irritating to skin.
