EC number: 942-425-2 | CAS number: -
Isomer 1 (alpha.R,1R,6S)- = 5.79, isomer 2 [1a(S*),6b] (9Cl) = 5.59The substance has potential for bioaccumulation; the data is relevant for classification in aquatic chronic toxicity hazard class according to Regulation (EC) No.1272/2008 (CLP) criteria (log Kow>4).
Two fully reliable experimental studies, conducted according to a recognized OECD/EC method and under GLP, are available. The slow-stirring method, considered of higher quality than the HPLC, was chosen as key study. The higher value (worst-case) is retained as key data.
The supporting HPLC study shows no difference between the isomers, that elute in a single peak.
Despite the substance was considered as surface-active (please refer to point 4.10), in the tests conditions, no surface-active behaviour is supposed to affect the validity of the two studies.
