80-70-6) is not readily biodegradable (according to OECD criteria),
therefore the substance is assessed to be potentially P or vP. The
substance is not expected to significantly bioaccumulate in organisms
(based on measured log Kow ≤ 3 and estimated BCF < 2000) and
is, therefore, not B or vB. According the experimental toxicity data on
algae, the substance is assessed to be not T (NOEC = 100 mg/L, Lonza
Ltd, 2017, limit test). According to the available acute toxicity data
of the substance to aquatic invertebrates and algae, no effects were
observed in the highest test concentration (100 mg/L, limit tests,
analytically verified, Lonza Ltd: daphnia: 2015, rep. no.: 698 -202
-0757; algae: 2017, rep. no.: 698 -201 -0756). Therefore, the lowest
available acute value is >> 0.1 mg/L and the substance holds no official
