Endpoint:
repeated dose toxicity: oral, other
Remarks:
Both subchronic and subacute data were used in the prediction. As a worst case, the prediction is submitted as subacute toxicity data.
Type of information:
(Q)SAR
Adequacy of study:

Study period:
2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The following prediction was performed using the OECD QSAR Toolbox using an appropriate category based on the current endpoint. The prediction was further refined using subcategories.
Justification for type of information:
A read-across justification report (RAAF) will be added to Section 13 as soon as possible.
Qualifier:

Version / remarks:
REACH Guidance on QSARs R.6, May/July 2008
Principles of method if other than guideline:
The repeat dose oral toxicity of the test material was evaluated using a read-across approach. Suitable analogues were found in the OECD QSAR Toolbox using the Organic Functional Groups category, and the results were refined using relevant subcategories.
GLP compliance:
no
Remarks:
As no laboratory work took place, compliance with GLP is not required.

Basis for effect level:
other: Based on the modelled conditions
Remarks on result:
other: The prediction was based on the average value from the 4 nearest neighbours compared by prediction descriptors.
Critical effects observed:

The prediction was based on dataset comprised from the following descriptors: NOEL

Estimation method: Takes average value from the 4 nearest neighbours

Domain logical expression: Result: In Domain

Substances used for the prediction should be:

Carboxylic acid<OR>Organic amide and thioamide<OR>Surfactants - Anionic (Organic functional groups)

Not categorized (Repeat dose (HESS))

Not bioavailable (Lipinski Rule Oasis)

Conclusions:
Based on the modelled conditions, the subacute NOAEL of the test material in the rat was determined to be ca. 73 mg/kg bw/day
Executive summary:

The repeat dose oral toxicity of the test material was evaluated using a read-across approach. Suitable analogues were found in the OECD QSAR Toolbox using the Organic Functional Groups profiler, and the results were refined using relevant subcategories (repeat dose (HESS) and lipinski rules oasis).

The target chemical falls within the applicability domain of the prediction.

Based on the modelled conditions, the subacute NOAEL of the test material in the rat was determined to be ca. 73 mg/kg bw/day.

Endpoint:
repeated dose toxicity: oral, other
Remarks:
Both subchronic and subacute data were used in the prediction. As a worst case, the prediction is submitted as subacute toxicity data.
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: read across conducted on QSAR assessment
Justification for type of information:
The test material is a mixture of many components. Comparison of all substances has shown that they are expected to have the same repeat dose toxicity. For the purpose of addressing the repeat dose endpoint the most concentrated component of the test material was assessed individually.
Reason / purpose for cross-reference:
read-across source
Dose descriptor:
NOAEL
Effect level:
73 mg/kg bw/day (nominal)
Based on:
test mat.
Sex:

Basis for effect level:
other: Based on the modelled conditions. Read across from the most concentrated component.
Remarks on result:
other: The prediction was based on the average value from the 4 nearest neighbours compared by prediction descriptors.
Remarks:
Read across from the most concentrated component.
Critical effects observed:
not specified
Conclusions:
Based on the modelled conditions, the subacute NOAEL of the test material in the rat was determined to be ca. 73 mg/kg bw/day.
Executive summary:

The potential of the component present at the highest concentration in the test material to cause repeat dose toxicity was modelled using the OECD Toolbox. The NOAEL was predicted to be 73 mg/kg bw/day. It has been shown, using read across, that all components are expected to have the same toxicity. Therefore, the NOAEL of the target chemical in rat is predicted to be 73 mg/kg bw/day.

Additional information

The repeat dose oral toxicity of the test material was evaluated using a read-across approach. Suitable analogues were found in the OECD QSAR Toolbox using the Organic Functional Groups profiler, and the results were refined using relevant subcategories (repeat dose (HESS) and lipinski rules oasis).

The target chemical falls within the applicability domain of the prediction.

Based on the modelled conditions, the subacute NOAEL of the test material in the rat was determined to be ca. 73 mg/kg bw/day.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008 (CLP), the substance does not require classification with respect to Specific Target Organ Toxicity repeated dose (STOT RE) via the oral route.
