This study examined the biodegradability of
the test substance. 34.3 mg/L of test substance was added to flasks
containing activated sludge. The amount of CO2 evolved was then measured
over the next 29 days. Sodium benzoate was used as a reference
substance. The reference substance was 89% degraded in 29 days.
Therefore the test is valid. The test substance was 85% degraded in 29
days. The test substance is readily biodegradable.
dissociates in water to its constituents MEA and LAS, both of which are
readily biodegradable. MEA-LAS can therefore be considered to be readily
A study was conducted to examine the
biodegradability of C10-13 LAS, sodium salt, according to OECD Guideline
301B, in compliance with GLP. 34.3 mg/L of test substance was added to
flasks containing activated sludge. The amount of CO2 evolved was then
measured over the next 29 d. Sodium benzoate was used as a reference
substance. The reference substance was 89% degraded in 29 d, therefore
the study was valid. The test substance was 85% degraded in 29 d and can
be considered readily biodegradable (Anon, 2002).
A DOC die away test according
to OECD Guideline 301A was conducted with MEA. The substance (20 mg/L in
the test system) was degraded by >90% within 21 d and is therefore
considered to be readily biodegradable (BASF, 1995).
