Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The adsorption coefficient (Koc) of Pseudo Kharismal Step 1 on soil or sewage sludge was estimated using high performance liquid chromatography (HPLC). Log Koc=2.96+/-0.01. In general, substances with log Koc values greater than 3 are hightly bound to organic matter in soil (FDA, 1987). Pseudo Kharismal Step 1 is likely to be bound to organic matter in soil.
- Executive summary:
The adsorption coefficient (Koc) of Pseudo Kharismal Step 1 on soil or sewage sludge was estimated using high performance liquid chromatography (HPLC). Log Koc=2.96+/-0.01. In general, substances with log Koc values greater than 3 are hightly bound to organic matter in soil (FDA, 1987). Pseudo Kharismal Step 1 is likely to be bound to organic matter in soil.
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.
