Description of key information
Additional information
Stearamide is regarded as readily biodegradable according to the results for the structural similar substance Amides, C16-C18 (even numbered) of > 60 % degradation in a CO2 evolution test (OECD 301B).
Stearamide is an amide of stearic acid (> 80%). In the fatty acid nomenclature, these fatty acids are denoted C18 and C16, respectively, due to the length of their carbon chains. The substance Amides, C16-18 even numbered differs from the stearamide only in composition (< 80% C18). For decades, stearamide and Amides, C16-C18 (even numbered) have been considered as different purity grades of the same substance and have been marketed as stearamide (CAS 124-26-5). Due to the conventions laid down in the "Guidance for identification and naming of substances under REACH and CLP" these different purity grades now have to be considered as different substances and are subject to separate registrations. It is therefore considered valid to read-across the results for Amides, C16-C18 (even numbered) to fill the data gap for stearamide.
This finding is further corroborated by the fact that the structural related substances erucamide and oleamide have consistently been shown to be readily biodegradable. Considering stearamide as readily biodegradable, further simulation testing on sediment and soil is not required.
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.
