Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
In a guinea pig maximization test (BASF 1991) according to the current guidelines a test group of 10 animals received 5 % thiodiglycol in aqueous solution for intradermal induction, followed by percutaneous induction with 0.3 g undiluted thiodiglycol under occlusive dressing for 48 hours. For challenge 0.15 g thiodiglycol (75 % solution in water; no irritating effect at this concentration) was applied to the intact skin for 24 hours (occlusive). The challenge resulted in no skin reaction, neither in thiodiglycol treated animals nor in negative controls. All 20 animals treated with the positive control substance 1-chloro-2,4-dinitrobenzene showed sensitization effects. In a further guinea pig maximization test (Elf Aquitaine 1998) according to OECD guideline 406 no cutaneous reactions were observed after the challenge application. Conclusion: In the guinea pig maximization test no sensitising effects were detected. No data are available on humans.

Justification for classification or non-classification
Classification for sensitisation is not warranted according to the criteria of EU Directive 67/548/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
