Conclusions:

In a reliable and conclusive study, the test substance is considered as slightly irritant only due to the results of the HET-CAM study and the comparison with the stimulation potential of the reference substance. Based on the long-term experiences on the comparibility of these in vitro results with in vivo results, the test substance is considered to be not irritating to mucosa membranes or eyes in a Draize test.

Executive summary:

The potential of the test substance for irritating the chorion allantois membrane (CAM) of fertilized and incubated hen eggs was determined in the in vitro HET-CAM test.

The relative stimulation potential of the test substance (> 85 %, undissolved) and the reference substance Texapon ASV (5%) was determined by using the reaction time method. The reference substance in the selected test concentration is assessed as moderately irritating in the Draize test on the rabbit eye.

The stimulation potental Q of the undissolved test substance Sandalice - S 544 (> 85 %) is smaller (Q=0.29) than the reference substance Texapon ASV (Q=1.00).

For the assessment of in vitro results the following values of the relative stimulation potential are defined:

Q </= 0.8 (slightly irritating)

0.8 < Q < 1.2 (moderatly irritating)

1.0 </= Q < 2.0 (irritating)

Q >/= 2.0 (strongly irritating)

Regarding the results, the test substance (> 85 %) is assessed as less irritating than Texapon ASV (5 %). Based on the long-term experiences on the comparibility of these in vitro results with in vivo results, the test substance is considered to be not irritating to mucosa membranes or eyes (Draize test).

Interpretation of results:

GHS criteria not met

Conclusions:

According to the GHS and CLP criteria for classification of the eye irritancy potential, based on the grading of ocular lesions as described in OECD 405 guideline, the tested substance should not be classified for eye irritancy under the test conditions

Executive summary:

A sample of the test item was tested in the rabbit acute eye irritation/corrosion test to determine its possible irritating or corrosive effects. Approximately 0.1 mL of the test substance was instilled into one of the eyes of nine female albino rabbits, three of which subsequently received remedial irrigation. The unwashed eyes reacted to contact with the test substance by corneal damage, involving the epithelium and in some cases also the stroma, slight iridial irritation and moderate conjunctival reddening and swelling. Remedial irrigation appeared to have a positive effect on the degree of corneal injury but it hardly reduced the irritation of conjunctivae and iris. From these results a Draize score of 19.8 was obtained for unwashed eyes and 10 for remedially irrigated eyes (both at 24 hours). According to the Kay and Calandra scheme the test substance can be classified as moderately and mildly irritating, respectively. However according to the GHS (Globally Harmonized System of Classification and Labeling of Chemicals) and CLP regulation (Regulation (EC) No 1907/2006) scheme for classification of the eye irritancy potential, based on the grading of ocular lesions as described in OECD 405 guideline, the tested substance should not be classified for eye irritancy under the test conditions.

Endpoint conclusion

Endpoint conclusion:

Additional information

On eye irritation endpoint, three studies are available and considered together in a weight of evidence approach:

 

1)     In a primary eye irritation study according to OECD Guideline 405 (Acute Eye Irritation / Corrosion) under GLP conditions in 1996, the test substance shows a slight eye irritancy potential for cornea opacity. This result is just on the threshold which triggers the eye irritation classification of H319 Eye Irritant category 2 and therefore the substance is classified accordingly. All effects were reversible after 7 days except in one animal for which a slight redness of conjunctivae only was observed. This effect disappeared at the 14 day observation and was considered not relevant for classification in view of the other results of the other two available tests.

 

2)     In another test performed in 1986 according to the guideline as stated in the US Pharmaceutical Manufacturers Association 1977 under GLP conditions, the test substance showed a slight irritancy potential, but below the threshold of classification.

 

3)     Finally, in an In-vitro HET-CAM test performed in 1996, under GLP conditions, and conducted with the same batch as in the OECD 405 test, the substance showed a slightly irritant potential based on the comparison with a reference substance. According to the study director judgement, based on the long-term experiences on the comparibility of these in vitro results with in vivo results, the test substance is considered to be not irritating to mucosa membranes or eyes (Draize test).

 

Considering the results in a weight of evidence approach of the three reliable and conclusive tests, it was considered that the worst case scenario should be used for classification, based on the OECD 405 study. The substance is therefore classified as eye irritation classification of H319 Eye Irritant category 2.

 

On skin irritation one study is available:

In a primary skin irritation test performed in 1996 following OECD guideline 404 and under GLP conditions, the test item showed irritancy potential. Based on the results obtained and specifically on the scores obtained in erythrema the substance is classified as skin irritant category 2 (H315) based on the criteria set out in CLP regulation. According to the Dangerous Substances Directive (67/548/EEC): the substance is classified as irritating to skin (R38).

Justification for classification or non-classification

Eye Irritation:

Considering the results in a weight of evidence approach of the three reliable and conclusive tests, it was considered that the worst case scenario should be used for classification, based on the OECD 405 study. The substance is therefore classified as eye irritation classification of H319 Eye Irritant category 2.

Skin Irritation:

Based on the results obtained and specifically on the scores obtained in erythrema the substance is classified as skin irritant category 2 (H315) based on the criteria set out in CLP regulation.
