EC number: 905-898-6
CAS number: -
Based on data for the two major constituents the substance can be considered harmful to Daphnia, with an 48h EC value > 55 mg/L
The lowest reliable value for acute toxicity of DEA to Daphnia magna was
reported from a static test according to US EPA Guideline 600/3-75-009
(1975). Fifteen daphnids were exposed to each test concentration for a
total of 48 hours. Details on tested concentrations were not reported.
An analytical verification of the test concentrations was not carried
out. Temperature, pH, and oxygen content were determined at the
beginning and end of the test. Since measured pH values ranged from 7.4
to 9.4, alkaline pH effects might have contributed to the observed
mortality. Based on nominal concentrations, the 48 hour EC50was
55 mg/l (LeBlanc, 1980).
For triethanolamine (TEA), the key study identified for the acute
toxicity to aquatic invertebrates is a test performed by Warne et al.
(1999) according to ASTM Designation E1192. Using Ceriodaphnia dubia as
test species in a static procedure an EC50 of 609.88 mg/l after 48 hours
of exposure was calculated related to the nominal concentrations. Hence,
the chemical is considered to be acutely not harmful for invertebrates.
The 48 hr EC50 value for the multiconstituent substance is estimated to
be > 55 mg/L, based on the results with DEA.
