Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Justification for type of information:
- For the REACH registration of dilithium tetraborate, a theoretical statement was prepared stating that in accordance with the REACH Regulation, the study on the adsorption coefficient (Koc) on soil and on sewage sludge cannot be performed using High Performance Liquid Chromatography (HPLC) method as described in OECD guideline 121 for an inorganic substance or mineral salt test item such as dilithium tetraborate. This statement is also applicable for the UVCB-Reaction products of boric acid and lithium hydroxide. Read across to the theoretical statement prepared for dilithium tetraborate is proposed to cover the adosprtion/desorption endpoint for the REACH registration of the UVCB-Reaction products of boric acid and lithium hydroxide.
- Remarks on result:
- not determinable because of methodological limitations
- Remarks on result:
- not determinable because of methodological limitations
- Validity criteria fulfilled:
- yes
- Conclusions:
- The study on the adsorption coefficient (Koc) on soil and on sewage sludge cannot be performed using High Performance Liquid Chromatography (HPLC) method as described in OECD guideline 121 for an inorganic substance or mineral salt test item such as lithium tetrahydroxyborate.
- Executive summary:
For the REACH registration of dilithium tetraborate, a theoretical statement was prepared stating that in accordance with the REACH Regulation, the study on the adsorption coefficient (Koc) on soil and on sewage sludge cannot be performed using High Performance Liquid Chromatography (HPLC) method as described in OECD guideline 121 for an inorganic substance or mineral salt test item such as dilithium tetraborate.

Additional information
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.
