BIODEGRADATION SCREENING TEST

The registration substance is readily biodegradable in an OECD 301B CO2 Evolution test.

BIODEGRADATION IN SEWAGE TREATMENT PLANTS

Based on 'ready biodegradability' the REACH Guidance R16.5.4.4 proposes a Half-life in STP of 0.7 h (12 deg C).

BIODEGRADATION IN FRESHWATER AND MARINE WATER

Based on 'ready biodegradability' the REACH Guidance R16.5.4 proposes a Half-life in Freshwater of 15d (12 deg C) and for Marine water of 50d (12 deg C).

BIODEGRADATION IN FRESHWATER SEDIMENT

Lipids e.g. from algae are biotransformed in aerobic sediment dependent on the conditions rapidly e.g. with a Half-life as short as 0.6d at 12 deg C (Ming-Yi Sun et al, Organic Geochemistry, 2002, 33, 445 -459).

BIODEGRADATION IN SOIL

Lipids e.g. Glyceryl alkanoates are a common part of soil organic matter (Otto et al, Organic Geochemistry 2005, 36, 425-448) . Lipase enzymes from soil microorgisms like Enterobacter aerogenes or Arthrobacter are able to degrade soil lipids like Glyceryl alkanoates into their alkanoic acids rapidly with half-lives of 1-2 days only (Cipinyte et al, Biologija, 2009, 55 (3-4) 84-92).
