Additional information

There is no data available for the test substance. However, data is available for exposure of Daphnia magna to the Water Accommodated Fraction of a C30 -C60 hydrogenated polyalphaolefin and a C20 -C30 hydrogenated polyalphaolefin. At nominal loading rates of 125mg/l for 21 days, no adverse effects were seen on survival, growth and reproduction. Based on the results of this studies a NOELR of 125mg/l was determined for all biological endpoints studied for both substances. The result for this substance can be read across with confidence to the C28 -C80 hydrogenated polyalphaolefin "Pentadecane, 7-methylene mixed with 1-tetradecene, dimers and trimers, hydrogenated".
