Description of key information

No measured data are available for the short-term toxicity to fish of the registration substance. The assessment of effects is based on available data for its constituents. The available information suggests that the constituents of the registration substance would not be toxic at the limit of solubility. It is not recommended to attempt a test because of the extreme technical difficulties that are to be expected in maintaining exposure concentrations.

Key value for chemical safety assessment

Additional information

A 35-d NOEC value of >140 ug a.i./L has been determined for the effects of a structurally-analogous alcohol, pentadecanol branched, on the growth, survival and hatchability of the freshwater fish Pimephales promelas. No statistically significant effects were observed at the highest concentration tested. Spine curvature was observed in a few individuals in the treatment vessels.

The constituents of the substance has been estimated by expert judgement to be non-toxic in fish at the limit of solubility. The statement is based on the available data in the category group, which indicates that no toxicity is observed at the limit of solubility with alcohols with carbon chain lengths ≥C15.
