Additional information

Data on the biodegradability of propylparaben (CAS 94 -13-3) are presented in the dossier “Environmental and Health Assessment of Substances in Household Detergents and Cosmetic Detergent Products” by the Danish Ministry of Environment and Energy. Herein, results from a study according to OECD guideline 301 F are cited. In this test, 20 mg/L propylparaben were incubated for 28 days and a valid reference control was included. Based on the theoretical oxygen demand, ethylparaben attained 91.5% degradation in 28 days and can therefore be classified as readily biodegradable according to OECD criteria. Additionally data on anaerob degradation were presented in the dossier. The results show that the test item is not anaerob biodegradable.
