Additional information

One reliable key-study on biodegradation of AES (C12-18, 1-2.5EO) Na (CAS 68081-91 -4) is available (Richterich & Mühlberg, 2004). In that GLP-study aerobic degradation of the mixture was tested according to OECD guideline 301D (Closed Botle Test). Based on O2 -consumption 76% after 30 days was measured.
