EC number: 211-802-7
CAS number: 696-99-1
The biodegradability of the substance Lekutherm-Beschleuniger KU 6519
Neu was determined according to EU Method C.4-B (Determination of the
"Ready" Biodegradability - Modified OECD Screening Test). The studiy was
conducted in compliance with the Principles of Good Laboratory Practice
The test substance is suspended in a mineral medium, inoculated with a
mixed population of aquatic microorganisms and incubated for 28 days in
the dark at 22 +- 2 °C. During this period, the biodegradation of the
test substance is determined on the basis of the reduction in DOC.
Within 28 days, a degradation of 96 % was determined for
Lekutherm-Beschleuniger KU 6519 Neu. Lekutherm-Beschleuniger KU 6519 Neu
has to be classified as "Readily Biodegradable".
In parallel preparations with the reference substance aniline a
degradation of 92% was achieved within 14 days. All validity criteria of
the test method were met.
Within 28 days, a degradation of 96 % was determined for Lekutherm-Beschleuniger KU 6519 Neu. Lekutherm-Beschleuniger KU 6519 Neu has to be classified as "Readily Biodegradable".
