Reference
Endpoint:
adsorption / desorption: screening
Type of information:
other: An expert assessment was performed based on the physico-chemical properties of the constituents of the substance.
Adequacy of study:
key study
Study period:
February 06, 2017
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: An expert assessment was performed based on the physico-chemical properties of the constituents of the substance.
Qualifier:
no guideline followed
Principles of method if other than guideline:
An expert assessment was performed based on the physico-chemical properties of the constituents of the substance.
GLP compliance:
no
Type of method:
other: An expert assessment was performed based on the physico-chemical properties of the constituents of the substance.

Key result
Type:
other: An expert assessment was performed based on the physico-chemical properties of the constituents of the substance.
Remarks on result:
other: The adsorption-desorption study does not need to be conducted because the organic constituents of the substance have log10Koc and/or log10 Kow values that are below the adsorption trigger value of 3.
Validity criteria fulfilled:
not applicable
Conclusions:
Based on a weight of evidence approach, it has been concluded that the reaction mass of morpholine and 6-[(p-tosyl)amino]hexanoic acid, compound with morpholine (1:1) has an adsorption-desorption coefficient of <3 and a study is subsequently not required.
Executive summary:

An expert assessment was performed based on the physico-chemical properties of the constituents of the substance. A substance is regarded as having the potential for adsorption if it has a Log Koc or Log Kow of ≥3. The organic constituents of Reaction mass of morpholine and 6-[(p-tosyl)amino]hexanoic acid, compound with morpholine (1:1), in their ionised and un-ionised forms have Log Koc and/or Log Kow values that are below the adsorption trigger value of 3. Therefore in accordance with Column 2 of REACH Annex VIII, an adsorption-desorption study does not need to be conducted on the substance.
