Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the chemical structure and experimental data on the substance itself and analogue structure, systemic uptake, but not bioaccumulation is expected.
Key value for chemical safety assessment
- Bioaccumulation potential:
- no bioaccumulation potential
Additional information
The substance is a mixture of rosin-derived acids for which the conjugated double bond pairs have been mostly transformed to either aromatic rings or isolated double bonds, plus also insertion of a methyl substituent in some components via reaction with formaldehyde, with the subsequent whole then being transformed into the calcium salt by reaction of the carboxylic acid.
Dissociated carboxylic acids can be conjugated by phase II metabolism for better elimination. The UVCB mixture is of good solubility in octanol and of moderate solubilty in water (ca 150 mg/L). Systemic uptake is expected, but sufficient target structures for metabolism are available to exclude a potential for bioaccumulation. Structures of components are shown at the end of the chemical safety report, as part of the supporting data for read-across.
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.
