Constituent 1
In chemico test system
- Details on the study design:
- Solutions of DEXGLUTACYCLE were successfully analyzed by the validated DPRA analytical method (Envigo analytical method FIA/M101/15) in both Cysteine and Lysine containing synthetic peptides. With minimal (Cysteine) and no depletion (Lysine) of either peptide (an overall mean depletion 0.15% was achieved) in the presence of DEXGLUTACYCLE

Applicant's summary and conclusion
- Interpretation of results:
- other: no reactivity in either peptide therefore the prediction is a non-sensitiser
- Conclusions:
- Solutions of DEXGLUTACYCLE were successfully analysed by the validated DPRA analytical method (Envigo analytical method FIA/M101/15) in both Cysteine and Lysine containing synthetic peptides. There was minimal reactivity in the cysteine peptide and no reactivity in the Lysine peptide so DEXGLUTACYCLE with a mean depletion value of 0.15% is placed in the reactivity class of “no or minimal” and hence it is predicted by DPRA not to be a skin sensitizer.
