Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
