Description of key information
Key value for chemical safety assessment
Skin sensitisation
Link to relevant study records
- Endpoint:
- skin sensitisation: in vitro
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- an in vitro skin sensitisation study does not need to be conducted because adequate data from an in vivo skin sensitisation study are available
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Data provided by ECHA on request of Cytec Surface Specialties NV/SA. SNIF last update on 1993-10-25, UUID: SNIF-a53a2718-53ed-33b4-b9a3-440eef4897f2

- yes
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- The study was conducted before the requirement for LLNA as a basic study to perform was mandated in 2013.

- Conclusions:
- Under the study conditions, the test substance was sensitising to guinea pig skin.
- Executive summary:
A study was conducted to determine skin sensitization potential of the test substance to guinea pig according to the method described in EC Regulation 92/69/EEC. Pirbright white guinea pigs were used in the skin sensitisation study. The concentration of the test substance and vehicle tested in the induction and challenge was 5% in semi-liquid paraffin. Intradermal injections of the test substance caused well defined erythema and slight oedema at the test sites of more than 30% animals. Under the study conditions, the test substance was sensitising to guinea pig skin (Anonymous, 1993).
Referenceopen allclose all
Maximum concentration not causing irritating effect in a preliminary test was 100%.
Signs of irritation during induction: slight erythema was observed at application sites, treated with the vehicle alone, for up to 3 days and at sites treated with the test substance in vehicle, up to 5 days after application.
Evidence of sensitisation for each challenge concentration:
- 1st challenge: 4 out of 10,
- 2nd challenge: 8 out of 10
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)

Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Based on an in vivo skin sensitisation study, the test substance warrants a classification of Skin Sens 1B (H317: May cause an allergic skin reaction) according to EU CLP (EC 1272/2008) criteria.
