Description of key information
Skin:
In an in vitro skin irritation study according to OECD Guideline 439 (BASF Colors&Effects, 2017), a cell viability of 109.6 % was determined in reconstructed human epithelial cells.
In a Draize test according to Fed. Reg. 38, No. 187, § 1500.41, the test substance showed no skin irritating properties, when tested as 50 % aequous preperation (BASF SE, 1982).
Eye:
In an in vivo eye irritation study in rabbits according to Fed. Reg. 38, No 187, Paragraph 1500.42 (Draize test) (BASF SE, 1981), the test substance showed no eye irritating properties.

PREDICTION MODEL / DECISION CRITERIA
- The test substance is considered to be irritant to skin if the mean relative tissue viability with a test substance is less than or equal to 45 %.
- The test substance is considered to be non-irritant to skin if the mean relative tissue viability with a test substance is higher than 55 %.
- The test substance is considered to be borderline, if the mean relative tissue viability with a test substance is lesser than or equal to 55 % and higher then 45 %.
The „borderline"-evaluation (50 ± 5 %) was determined statistically using historic BASF data and hence considers the variance of the test method. This evaluation is confirming the borderline range provided in OECD Guideline 439. - Control samples:

Additional information
Skin irritation:
The objective was to assess the skin irritation and corrosion potential of the test substance. Using the currently available methods a single in vitro assay is not sufficient to cover the full range of skin irritating/corrosion potential of a substance. Therefore, two in vitro assays were part of this in vitro skin irritation and corrosion test strategy: The Skin Corrosion Test (SCT) and Skin Irritation Test (SIT) according to OECD Guideline 439. However, in the current case, the results derived with SIT alone were sufficient for a final assessment. Therefore the SCT was waived.
The potential of the test substance to cause dermal irritation was assessed by a single topical application of 25 µL (irritation test) of the undiluted test substance to a reconstructed three dimensional human epidermis model (EpiDerm™). The irritation test was performed with three EpiDerm™ tissues, which were incubated with the test substance for 1 hour followed by a 42-hours post-incubation period. Tissue destruction was determined by measuring the metabolic activity of the tissue after exposure/post-incubation using a colorimetric test. The reduction of mitochondrial dehydrogenase activity, measured by reduced formazan production after incubation with a tetrazolium salt (MTT) was chosen as endpoint. The formazan production of the test-substance treated epidermal tissues was compared to that of negative control tissues. The quotient of the values indicates the relative tissue viability. The test substance is not able to reduce MTT directly. The following results were obtained in the EpiDerm™ skin irritation test:
After an exposure period of 1 hour with about 42 h post-incubation, the mean viability of the test-substance treated tissueswasdetermined at 109.6 % (values for single tissues: 111.3 %, 101.4 % and 116.2 %). All acceptance criteria were met.
Based on this and applying the evaluation criteria it was concluded, that the test substance did not show a skin irritation potential in the EpiDerm™in vitro skin irritation test. For this reason, corrosion to skin could be excluded and the respective test was waived.
This finding is supported by the results of a Draize test according to Fed. Reg. 38, No. 187, § 1500.41 (BASF SE, 1982). The test substance (0.5 g, 50 % aequous preparation) was applied to the intact skin area of six vienna white rabbits under occlusive conditions for 24 h. Readings were performed after 24 and 72 h followed by an observation period of 8 days. A determination of the erythema score was not possible due to test substance-coloured skin. Mean edema score of all animals was 0.0, except for one animal (edema score 0.5). According to these results, the test substance did not show skin irritating properties.
Eye irritation:
In a Draize study (BASF SE, 1981) of acceptable quality (validation criteria 2), a sample of 11 mg (0.1 mL) test substance was tested in a group of 6 vienna white rabbits. The eyes were not washed after application. Irritation was scored at 24, 48, and 72 h after application. No further observation period was indicated.
A slight conjunctival redness was observed but was reversible within 2 days. No chemosis or iritis was observed. According to the test results, the test substance was not irritating to the eyes.
Following individual irritation mean scores (24, 48, and 72 h) were determined:
Cornea Opacity Score/Iris Score/Conjunctivae Score/Chemosis Score
Animal 1: 0.33/0/0.67/0
Animal 2: 0/0/0/0
Animal 3: 0/0/0.67/0
Animal 4: 0/0/0/0
Animal 5: 0/0/0.67/0
Animal 6: 0/0/0.33/0
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008.
No Eye and skin irritating properties were documented. As a result the substance should not be classified as eye irritating or skin irritating under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.
