Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to Annex XIII of the REACH Regulation (EC) No 1907/2006, a PBT substance has to fulfil all three of the criteria for persistence, bioaccumulation and toxicity, as listed in part 1 of Annex XIII, and a vPvB substance has to fulfil all criteria for persistence and bioaccumulation, as listed in part 2 of Annex XIII.
Fatty acids, C12 - 14 (CAS 90990-10-6) is not identified as PBT nor as vPvB substance on the basis of the relevant data provided below:
Persistence:
Several studies using standardized OECD, EU- and ISO test guidelines are available for fatty acids that could all demonstrate the ready biodegradability of the substance within 28 days. Therefore, the substance does not meet the Persistent (P) or very Persistent (vP) criteria.
Bioaccumulation:
The BCF value obtained for whole organisms after exposure to the fatty acid analogue substance C12 fatty acid sodium laurate is below the bioaccumulation criterion of BCF > 2000 set in Annex XIII of REACH Regulation (EC) No 1907/2006. In addition rapid metabolism of fatty acid within the organism is expected. Therefore, fatty acids are considered unlikely to be bioaccumulative.
Toxicity:
According to Annex XIII of REACH Regulation (EC) No 1907/2006, a substance is considered to be toxic in terms of PBT criteria if long-term NOEC values for aquatic organisms are lower than 0.01 mg/L. The worst-case NOEC obtained for daphnids, was ≥1.3 mg/L on the basis of read-across from decanoic acid (CAS 334-48-5). Therefore the toxicity criterion is not met and fatty acids, C12 - 14 (CAS 90990-10-6) is not considered as a toxic substance regarding ecotoxicological endpoints.
Moreover, the substance is not classified as carcinogenic, mutagenic or toxic for reproduction according to Regulation (EC) No. 1272/2008 and its further amendments.
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.
