Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: REACH Guidance on QSARs R.6 (QSPR model adapted specifically from OECD 404 test guideline)
- Principles of method if other than guideline:
- Multiple Quantitative Structure Activity Relationship (QSAR) models were used to predict the Acute Skin Irritation/Corrosion potential of the test item Piperonyl acetate. These QSAR models have been designed to be used for regulatory purposes and based on the QSAR results, this report predicts the consensus endpoint value which would be expected when testing the substance under experimental conditions in a laboratory following the OECD Guideline for Testing of Chemicals No. 404: Acute Dermal Irritation/Corrosion.
The in silico study aims to predict the acute skin Irritation/Corrosion of the test item using the following QSAR models:
* Danish QSAR Database
* OECD QSAR Toolbox v4.2 (profiling results)
* Nexus DEREK v6.0.1
The final consensus result for acute skin irritation/corrosion was derived by applying a consensus method on the reliable results derived for individual models.

As per the profiling results, the query substance will not be classified as skin irritant.
* Results with Nexus DEREK
No alerts for skin irritation were triggered. Therefore, the substance can be considered as non-irritant to the skin using this tool.
Applicant's summary and conclusion
