Additional information
Based on all the available information, toxicity to sediment organisms is not expected to be of concern.
No experimental data evaluating the toxicity of the target substance Docosyl stearate (CAS 21443-03-2) to sediment organisms are available. However, the substance is characterized by poor water solubility (< 0.504 mg/L, 20 °C, OECD 105) and only negligible discharge to the aquatic environment is expected to occur via sewage treatment plants (STPs) due to: a) the ready biodegradability and b) the high adsorption properties of the substance, resulting in an effective removal in sewage treatment plants. Whatever fraction should still reach the water compartment is expected to undergo rapid and ultimate degradation and the remainder will adsorb to organic soil and sediment particles where sediment organisms are potentially exposed via feed and contact with suspended organic particles. However, based on the physico-chemical properties, the bioavailability of the substance is expected to be low due to its strong binding behavior. Therefore, chronic exposure of sediment organisms is unlikely. Furthermore, the substance is not toxic to aquatic organisms up to the limit of water solubility.
Based on all the available information, toxicity to sediment organisms is therefore not expected to be of concern.
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.
