Description of key information
As the parent compound rapidly hydrolyses in aqueous systems the assessment of the biodegradability is based on the hydrolysis product lauric acid, which is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Parent compound lauroyl chloride and hydrolysis product lauric acid:
As lauroyl chloride (CAS 112 -16 -3) rapidly hydrolyses in aqueous systems the assessment of the biodegradability is based on the hydrolysis product lauric acid (CAS 143 -07 -7) and its sodium salt (sodium laurate, CAS 625 -29 -4). The biodegradability is assessed based on a weight of evidence approach. No data are available for lauroyl chloride.
The following data are available:
Lauroyl chloride (CAS 112 -16 -3):
1) BASF SE (2011): EPI Suite v4.10 SRC BIOWIN v4.10: readily biodegradable
Lauric acid (CAS 143 -07 -7):
1) VCI Ringtest (1980): respirometry (Sapromat), inoculum not specified: removal degree: 72% after 9 d
2) BASF SE (2011): CATALOGIC v5.10.8 BOD 28 days MITI (OECD 301 C) v3.04: removal degree = 99% after 28 d; readily biodegradable
3) BASF SE (2011): CATALOGIC v5.10.8 BOD Kinetic (OECD 301F beta v.06.08: removal degree = 79% after 28 d, 10 -d window kept; readily biodegradable
4) BASF SE (2011): EPI Suite v4.10 SRC BIOWIN v4.10: readily biodegradable
5) ECHA (2012): OECD 301D, activated sludge (domestic, non-adapted): removal degree 86% after 30d; readily biodegradable according to OECD criteria
Sodium laurate (CAS 625 -29 -4):
1) Abe et al. (1984): DOC die-away test: 100% after 15 d (river water as inoculum); readily biodegradable
2) Mix-Spagl (1990): Sapromat: BOD5: 85%; BOD10: 100%; inoculum not stated; biodegradable
In conclusion lauroyl chloride and its hydrolysis product lauric acid are assessed to be readily biodegradable. However, as the parent compound rapidly hydrolyses in aqueous system, the QSAR estimate (EPI Suite v4.10 SRC BIOWIN v4.10) for lauroyl chloride may be of low relevance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
