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.
