- Details on the study design:
- Cysteine peptide
Name: Cysteine peptide
Batch: 111016HS-MHeW0321
Storage: at -20°C or below
Purity: 90.1 %
Molecular weight: 750.88 g/mol
Sequence: Ac-RFAACAA-OH
Expiry date: September 10, 2021 - Vehicle / solvent:
- acetonitrile
- Positive control:
- cinnamic aldehyde
Results and discussion
- Positive control results:
- positive control, from
absorbance at 220 nm measuring the peak area of the appropriate peaks and calculating the
concentration of the peptide using the linear calibration curves derived from the calibration
standards
the mean percent peptide depletion value of the three replicates for the positive control
cinnamaldehyde should be between 60.8% and 100% for the cysteine peptide and between
40.2% and 69.0% for the lysine peptide and the maximum standard deviation (SD) for the
positive control replicates should be < 14.9% for the percent cysteine depletion and
< 11.6% for the percent lysine depletion

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (skin sensitising) based on GHS criteria
- Conclusions:
- Based on these results and the cysteine 1:10 / lysine 1:50 prediction model, the test item
“1133-Tetrachloropropene” was concluded to be positive and to show high reactivity
towards the synthetic peptides thus is a potential skin sensitizer under the
experimental conditions of the in chemico Direct Peptide Reactivity Assay (DPRA)
method. - Executive summary:
