Additional information:

No human data are available with regard to the endpoint skin sensitization. However, the skin sensitization potential of the close structural analogue compound C16 -18 -(even numbered)-alkylamines acetates was investigated in a guideline conform maximization test in male guinea pigs according to Magnusson and Kligman. 10 test and 5 control animals were used. Based on the results of sighting tests, 0.5% (w/v) for the intradermal induction, 3% (w/v) for the topical sensitization as well as 0.5% (w/v) for the dermal challenge phase were selected as concentrations of the test material. As vehicle for the dermal treatments vaseline was used. Under the conditions of this test, C16 -18 -(even numbered)-alykylamine actetates produced a 10% (1/10) sensitization rate and was classified as a non-sensitizer to guinea pigs. In addition, animal data also exist on the structural and functional similar C12 -18 -(even numberd)-alkylamines from a GLP-compliant Magnusson and Kligman maximisation test which demonstrated absence of a significant skin sensitizing potential as well. From both studies no significant skin sensitization potential of C12 -18 -(even numbered, C18 -unsaturated) -alkylamines acetates is deducible. Additionally, since the registration substance is considered to exhibite strong dermal irritative / corrosive properties, dermal exposure has to be limited.


Migrated from Short description of key information:
No human data are available with regard to the endpoint skin sensitization. The registration substance is considered to be corrosive to skin and thus testing is not considered justified based on animal welfare grounds. However, a guideline conform maximization test according to Magnusson and Kligman (OECD TG 406) in guinea pigs with the close structural analogue substance C16-18-(even numbered)- alkylamines acetates showed no evidence for skin sensitising properties. In addition, testing with the structural and functional similar C12-18-(even numbered)-alkylamines in a GLP compliant Magnusson and Kligman maximisation test also revealed no indications of a skin sensitization potential. Based hereupon, the registration substance is not considered to be a skin sensitizer.

Justification for selection of skin sensitisation endpoint:
Data on this endpoint is not available for the registration substance. Testing of C12-18-(even numbered, C18 unsaturated)-alkylamines acetates for skin sensitization is scientifically not justified because of animal welfare reasons. This alkylamine acetate is classified as corrosive to skin and testing for skin sensitization irritation is therefore generally not needed according to REACH regulation (EC) 1907/2006 (Annex VII, point 8.2, column 2 [in vivo, step 2]). However, testing of analogous fatty amine acetetates as well as primary fatty amines revealed no skin sensitizing potential.

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available
Additional information:

The registration substance is corrosive to skin and thus testing is not warranted. Based on data from structural and functional closely related C12-18-(even numbered)-alkylamines which are devoid of skin sensitizing potential, a respiratory sensitization potential of C12-18 -(even numbered, C18 unsaturated)-alkylamines acetates is not to be expected.
