Adsorption / desorption

Administrative data

Endpoint:

adsorption / desorption: screening

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter

Cross-reference

Cross-reference 1

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

partition coefficient

Type of information:

(Q)SAR

Adequacy of study:

key study

Reliability:

3 (not reliable)

Rationale for reliability incl. deficiencies:

results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification

Justification for type of information:

Substance is insoluble in water, and is to have an expected partition coefficient above 8, and thus suggested OECD methods are not applicable.

Qualifier:

no guideline followed

Principles of method if other than guideline:

Calculated, KOWWIN programme v1.68; Estimation Programs Interface Suite™ for Microsoft® Windows, v 4.00. United States Environmental Protection Agency, Washington, DC, USA.

GLP compliance:

no

Key result

Conclusions:

Estimated Log Kow = 19.31

Cross-reference 2

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

GLP compliance:

not specified

Type of method:

column elution method

Key result

Water solubility:

< 0.1 mg/L

Conc. based on:

test mat. (dissolved fraction)

Temp.:

20 °C

pH:

>= 6.4 - <= 6.5

Conclusions:

Preliminary test, in accordance with OECD Method 105 (visual assessment), showed that the water solubility of the test substance is below the detection limit of the analytical method (0.1mg/L). Consequently, the substance appears to be insoluble in water. In reference to Annex VII of REACH, if the substance appears to be insoluble in water, then the “limit test up to the detection limit of the analytical method shall be performed”. Based upon this information, the water solubility of the test substance shall be reported at <0.1mg/L. The water solubility was determined at 20°C. The pH value of the collected aqueous fraction was a range of 6.4-6.5.

Cross-reference 3

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

partition coefficient

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance does not dissolve in water or in octanol

Justification for type of information:

The substance is not soluble in water (< 1 mg/L).
