Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
In vitro studies covering three key steps of the adverse outcome pathway for skin sensitization as identified by the OECD (OECD Publication No.168; ENV/JM/MONO(2012)10) were performed. These study types have undergone in-house validation using 54 substances (Bauch et al., 2012 Regul Toxicol Pharmacol. 63: 489-504) and methods for keratinocyte activation and dendritic cell activation are in the final stages of validation at ECVAM (http://ihcp.jrc.ec.europa.eu/our_labs/eurl-ecvam/validation-regulatory-acceptance/topical-toxicity/skin-sensitisation). The ECVAM opinion on the direct peptide binding assay has been published on Dec 13, 2013. Based on the results of the in house validation (Bauch et al., 2012 Regul Toxicol Pharmacol. 63: 489-504) the predictive capacity of the evaluation scheme using DPRA (peptide reactivity), LuSens/KeratinoSens™ (keratinocyte activation) and (m)MUSST/h-CLAT (dendritic cell activation) is comparable to that of the local lymph node assay. When compared to the sensitization potential of the substances in humans, the classification based on an evaluation scheme using results obtained from the DPRA, LuSens and mMUSST had a sensitivity of 93%, a specificity of 95% and an accuracy of 94%. This publication was also referenced by the OECD in the AOP guidance document. Furthermore, it is also in line with the recently published strategy by ECVAM (EURL ECVAM, JRC79446, doi:10.2788/84214; 2013).
In the evaluation scheme used here any two of the three test results determine the overall classification, i.e. any two positive test results drive the prediction of a sensitizer, while any two negative test results drive the prediction of a test substance to be a non-sensitizer (Bauch et al. 2012; Table 1). If two assays (DPRA, LuSens or KeratinoSens, MUSST or h-CLAT) yield concordant results, the result of the third assay is not necessarily required to determine the overall outcome of the evaluation scheme.

Each individual assay was performed under GLP and the cell based assays LuSens and h-CLAT consisted of at least two independent experiments. Positive and negative controls were included in each experiment and confirmed the functionality and validity of the individual assays.
The test battery applicability is limited when testing substances insoluble in the commonly used vehicles and highly volatile substances. Substances susceptible to base-catalyzed hydrolysis cannot be evaluated reliably for binding to lysine as the incubation is performed at pH 10.2. Also substances that interfere with the experimental measurements (e.g., co-elution with the peptide in the DPRA-assay) are not or only partially suitable for testing using in vitro methods. The substance under evaluation did not have any of the above mentioned limitations and the outcome of this assay is therefore considered adequate for hazard identification for the endpoint of skin sensitization.
The test substance Reaction product of Saccharose, Glycerine, biodiesel propoxylated is negative in the DPRA assay, negative in the LuSens assay and positive in the hCLAT assay. In accordance with the published evaluation scheme (Bauch et al., 2012 Regul Toxicol Pharmacol. 63: 489-504) and Sections 1.2 and 1.4 of Annex XI of EC regulation 1907/2006, Reaction product of Saccharose, Glycerine, biodiesel propoxylated is judged not to be a skin sensitizer.
Migrated from Short description of key information:
Sensitization involves a number of key steps in order to take place, and can be described in terms of an adverse outcome pathway (AOP). These include reactivity with skin proteins (peptide reactivity), activation of skin cells (keratinocyte activation) and immune cells (dendritic cell activation). The studies carried out for the test substance address these three key steps. The results are then used in a predefined evaluation scheme to determine hazard classification as a sensitizer by a weight-of-evidence approach.
