Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 271-685-3 | CAS number: 68604-33-1 This substance is identified by SDA Substance Name: C14-C18 and C16-C18 unsaturated alkyl carboxylic acid ammonium salt and SDA Reporting Number: 04-006-01.
Endpoint summary
Administrative data
Description of key information
DSD (67/548/EEC): Based on read across studies, the readily biodegradation of the substance and taking into account the provisions laid down in Directive 67/548/EEC the substance is not considered to be classified as dangerous for the environment (to aquatic organisms / in aquatic environment).
GHS/CLP (Regulation (EC) No 1272/2008): Based on the read across studies, the readily biodegradation of the substance and taking into account the provisions laid down in Regulation (EC) No 1272/2008 the substance is considered to be classified as chronic hazardous to the aquatic environment Category 3 (Aquatic Chronic 3 H412).
Classifcation for hazardous to the aquatic environment according to UN-GHS: Aquatic Acute 2 H401 (Toxic to aquatic life.) and Aquatic Chronic 3 H412 (Harmful to aquatic life with long lasting effects.).
Additional information
Fish: Based on read across studies for short term toxicity to fish on chemically similar substances the LC50(fish, 96h) for Fatty acids, C14-18 and C16-18-unsatd., ammonium salts is estimated to be >=21 mg/l.
Daphnia: Based on read across studies for short-term and long-term toxicity to aquatic invertebrates on chemically similar substances, for Fatty acids, C14-18 and C16-18-unsatd., ammonium salts the EC50(daphnia, 48h/24h) is estimated to be >=4.2 mg/l and the NOEC(daphnia, 21d): >=0.11 mg/L.
Algae: Based on read across studies for toxicity to alga on chemically similar substances, for Fatty acids, C14-18 and C16-18-unsatd., ammonium salts the ErC50(algae, 72h) is estimated to be >44 mg/l and the NOEC(algae, 72h): >=2.6 mg/L.
Biodegradation in water: Based on read across studies for biodegradability on chemically equal or similar substances the target substance Fatty acids, C14-18 and C16-18-unsatd., ammonium salts is readily biodegradable (OECD Guideline 301B(28d): 93%, the “10 -days-window” was met; OECD Guideline 301D(28d): 92% ).
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).
