>10g/l (maximum tested concentration)

Key value for chemical safety assessment

Additional information

A C20 -C30 hydrogenated polyalphaolefin was investigated for its chronic toxic effect on bacteria (Pseudomonas putida) according to DIN 38412 Part 8, up to a maximum concentration of 10g/l in water. Under the conditions of this study no toxic effect could be observed and therefore a toxic concentration could not be defined. The toxicity to micro-organisms of Pentadecane, 7-methylene mixed with 1-tetradecene, dimers and trimers, hydrogenated is likely to be similar to this tested substance
