Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Sodium propylparaben (CAS 35285-69-9) is considered readily biodegradable. 91.5% degradation were attained in 28 days.
Additional information
No studies investigating the biodegradability of sodium propylparaben (CAS 35285-69-9) are available. Therefore, biodegradation data of the corresponding acid propylparaben (CAS 94-13-3) are used as read across.
This read across approach is in accordance with Regulation (EC) No 1907/2006, Annex XI, 1.5. Grouping of substance and read across approach as is explained within the analogue justification in section 13. Except for different cations (hydrogen vs. sodium) the anions of both the source and target substance have identical chemical structures. Since dissociation of the sodium salt under environmental conditions (pH 4 - 9) yields the same ionic species as the acidic form of the substance, this read across can be considered as justified.
Based on this analogue read across sodium propylparaben (CAS 35285-69-9) is considered readily biodegradable. 91.5% degradation were attained in 28 days.
Data on biodegradation in water & sediment and in soil are not mandatory.
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.
