Description of key information
Additional information
The substance Di-Pentaerythritol is stable to hydrolysis i.e. estimated half-life of greater than one year under typical environmental conditions.
The substance Di-Pentaerythritol is not readily biodegradable or inherently biodegradable.
The logKow of Di-Pentaerythritol is reported to be -1.8 (see Section 4.7, partition coefficient). According to Column 2 of Annex IX of the REACH regulation, no study is required if the logKow is below the trigger of 3 as the substance can be expected to have a low potential for bioaccumulation.
Based on the logPow value (OECD 117, is -1.8), the substance Di-Pentaerythritol can be expected to have a low potential for adsorption. According to Column 2 of Annex VIII of the REACH regulation, no adsorption/desorption study is required if the logPow is below the trigger of 3 as the substance can be expected to have a low potential for adsorption.
According to REACH Regulation (EC) No. 1907/206, Annex IX, Sections 9.2.1.3 and 9.2.1.4, simulation testing for the sediment and soil is only suggested for substances that have a potential for adsorption to soil. For Annex VI and XI substances a high potential to absorb is classified as a Log Kow of >5 or a Log Koc of >3. The substance has a log Kow of -1.8 (Log Koc not available), and therefore is not deemed to be highly adsorptive substance.
In accordance with REACH Regulation (EC) No. 1907/206, Annex IX, Section 9.2.1.2 for substances manufactured above 100 tpa, an Aerobic Mineralization in Surface Water- Simulation Biodegradation test is proposed for Di-Pentaerythritol.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
