Additional information

Two guideline studies investigating the ready biodegradability of Citronellol are available. The biodegradation of the substance was tested in a Manometric Respirometry Test according to EU Directive 79/831/EEC Annex V, part C using domestic activated sludge as inoculum. At test termination after 28 days Citronellol was degraded by 80 - 90 % (BASF AG, 1986). In a BOD5 test according to German standard DIN 38409 part 51 and 43 a BOD5*100/COD of 61 was determined. The results demonstrate that Citronellol is readily biodegradable according to OECD criteria.
