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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 273-179-8 | CAS number: 68952-95-4 A complex combination of fatty acids, neutral vegetable-oil, proteins, and other minor components produced by boiling vegetable-oil soapstock with mineral acid and, optionally, further separating the oil phase acidulated soapstock from the aqueous phase.

Description of key information
Overall, the weight of evidence suggests that ‘soaps, stocks, vegetable oil, acidulated’ will not bioaccumulate in aquatic or terrestrial organisms, even after repeated exposure.
Additional information
‘Soaps, stocks, vegetable oil, acidulated’ presents low solubility in water and is readily biodegradable. As such this would lead to relatively low concentrations of the substance in the aquatic environment thereby leading to low concentrations in aquatic organisms. Further, the low estimated BCF values from QSAR models as well as from an in vitro bioaccumulation study (Freitag, 1985) together with toxicokinetic information from mammals, all suggests that none of the constituents is likely to bioaccumulate significantly in aquatic or terrestrial organisms. In addition the fish has metabolic potential to break down the triglycerides and their constituent fatty acids and use as an important source of metabolic energy for growth and reproduction (Tocher, 2003).
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.
