Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption, other
- Type of information:
- other: expert assessment
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The assessment is based on the degree of adsorption of the hydrolysis products of the registered substance.
- Justification for type of information:
- The assessment is based on the degree of adsorption of the hydrolysis products of the registered substance.
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The assessment is based on the degree of adsorption of the hydrolysis products of the registered substance.
- GLP compliance:
- no
- Type of method:
- other: expert assessment
- Type:
- log Koc
- Value:
- < 3
- Remarks on result:
- other: see 'other information on results'
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The substance has a low potential for adsorption.
- Executive summary:
In accordance with Column 2 of REACH Annex VII and the ECHA guideline documents on information requirements, the adsorption-desorption study does not need to be conducted because vinyl chloroacetate decomposes rapidly and the degradation products produced have low potential for adsorption. The Log Kow values for acetaldehyde and chloroacetic acid (the major products of vinyl chloroacetate hydrolysis) are well below the adsorption trigger value of 3. Therefore it can be considered that vinyl chloroacetate has a low potential for adsorption.

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.
