Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Justification for type of information:
- Guinea Pig maximisation study performed on amine
This is considered suitable to assess the ammonium salt as ammonium ions are known not to be potential sensitisers.

- Details on study design:
- RANGE FINDING TESTS:
intradermal injection ( determination of Maximal Non Necrotizing Concentration: MNNC)-0.1 ml of the test material at 5, 10, 25 and 50% in isotonic sodium chloride. Necrosis was seen in all dose levels, and hence, lower concentrations were tested: 0.2, 0.5, 1 and 2%
topical application
1.determination of the Pre-Maximal Non Irritant Concentration (Pre-MNIC): 10, 20, 50, 100% in distilled water, 24 h with occlusive dressing. Excessive irritation was seen, and therefore, two more animals were tested at 7.5% and 5% in water.
2. determination of the Maximal Non Irritant Concentration: 1, 2, 5 and 10% in distilled water

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:

- Executive summary:
In a dermal sensitization study with BIO-SOFT 411 -E (97% benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with 2 -propanamine (1:1), ten young adult Dunkin-Hartley guinea pigswere tested using the method of Magnusson and Kligmann according to OECD 406.α-Hexylcinnamaldehyde was used as a positive control material. No cutaneous reaction attributable to allergy was recorded in animals from the treated group after the challenge phase, with the test item at 0.25% and 0.5%. No cutaneous intolerance reaction was recorded in animals from the negative control group after the challenge phase, on the treated area with the test item at 0.25% and 0.5%.
In this study, benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with 2 -propanamine (1:1) is not a dermal sensitizer.
