Additional information

No data on target substance was available, thus available data on Similar Substance 01 was used. Similar Substance 01 is one component of the target UVCB substance; it is one of the major components, ranging between 10 - 60 % w/w. Other components show slight differences in terms of position / type of functional groups. Further details are available in section 13.

Acute toxicity of test substance to fish was assessed in a 48 -hour study on trout. Only a summary of results was available. In particular, no mortality was seen up to the highest tested dose of 1000 mg/l, thus TL50 > 1000 mg/l. Purity of test sample was 75 %. As no details were available, such result was only taken as a qualitative indication of low toxicity.
