Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (LLNA)
- Type of information:

- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study published in a peer-reviewed literature, using the standard method; brief reporting, but acceptable for assessment.

- No data are provided.
Study design: in vivo (LLNA)
- Vehicle:

- No. of animals per dose:
- 4/dose
- Details on study design:
- Groups of 4 mice were treated with 25 μl of test material on the dorsum of both ears. Treatment was performed once daily for 3 consecutive days. Five days following the initiation of exposure all mice were injected via the tail vein with 250 μl phosphate buffered saline containing 20 μC tritiated thymidine. Mice were killed 5 hours later and the draining lymph nodes excised and pooled for each experimental group. A single cell suspension of lymph node cells is prepared by mechanical disaggregation, washed twice in excess of PBS, then precipitated with 5% trichloroacetic acid at 4 ˚C for 18 hr. Pellets were resuspended in trichloroacetic acid and incorporation of tritiated thymidine was measured by β-scintillation counting.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
