EC number: 701-248-9
CAS number: -
Short-term toxicity to aquatic invertebrates of the substance is derived using read across. EC 500-029-3 was determined to result in a 3 hour EC2 > 720 mg/L, EC 500-044-5 in a 3 hour-EC10 > 10,000 mg/L and EC500-118-7 in a 3 hour-NOEC >= 10,000 mg/L. Overall it can be assumed that all three read across substances give a 3 hour-NOEC >= 10,000 mg/L.
In a read across approach studies of
three read across substances were used to describe toxicity to
microorganisms of the substance.
for the read-across approach:
mass of Glycerol, propoxylated and Sucrose, propoxylated;Succhrose,
propoxylated; Propylidynetrimethanol, propoxylated; Glycerol,
propoxylated; Propane-1,2-diol, propoxylated; Pentaerythritol,
propoxylated; Trimethylolpropane, ethoxylated; Diethylene glycol,
propoxylated; Ethylene glycol, propoxylated; Diethanolamine,
substance is member of a group of chemicals with similar chemical
structure and physical behaviour:
Chemical similarity: All of these substances have terminal OH-groups and
ether-linkages as common structural features. Thus, the substances
differ from each other only in the identity/type of starter molecule
(aliphatic alcohols with 2 to 8 hydroxy functions) used and its
associated bonding with the alkoxylate repeating units. Typically the
products are substances with a range of Ethyleneoxide or Propyleneoxide
units (1 -12.5) added to starter molecules. All substances are
characterised by a molecular weight distribution of ca. 150 - 1000. The
common function of the members of the group is to allocate a high number
of hydroxy functions which are intended to react with e.g. an isocyanate.
