EC number: 273-234-6 | CAS number: 68953-96-8 This substance is identified by SDA Substance Name: C11-C13 branched alkyl benzene sulfonic acid calcium salt and SDA Reporting Number: 25-097-06.
PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Branched CaDDBS is not considered to meet the criteria for a PBT. The available data demonstrate that while the substance is not likely to be readily biodegradable, it does degrade almost entirely over an extended period of time. The Log Kow suggests that the substance may bioaccumulate but modeling of four representative structures indicates that it should not be bioaccumultive. Toxicity of the substance is moderate, with the lowest chronic NOEC of 0.23 mg/L above the limit used to classify as toxic for PBT purposes. No other toxicity characteristics are evident in mammalian testing that would meet the requirements for PBT.
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.
