Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
Testing for sensitising properties of Phenylsulfonat CA (Branched CaDDBS0 was performed in female Guinea pigs according to OECD Guideline 406 methods. Intradermal induction was performed using 0.2% Phenylsulfonat CA in semi-liquid paraffin. Dermal induction was carried out with 3% Phenylsulfonat CA in petrolatum. 0.1% Phenylsulfonat CA in petrolatum was selected for the challenge treatment. Results show no evidence for sensitisation. Phenylsulfonat CA (Branched CaDDBS) is therefore not a dermal sensitiser.
Migrated from Short description of key information:
Phenylsulfonat CA (Branched CaDDBS) was tested for sensitising properties in guinea pigs. No positive reactions were observed and therefore the test material is not considered to be a skin sensitiser.
Justification for classification or non-classification
Based on the lack of reactions in a guinea pig skin sensitisation study, Branched CaDDBS will not be classified under the DSD or CLP.
