Executive summary:

 In a dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, 0.5 mL of Aqualenc F was applied on the clipped skin of 3 males New Zealand White rabbits.

An initial test was performed in one animal with exposure periods of 3 minutes and 4 hours. No cutaneous reactions were observed after an application of 3 minutes. A confirmatory is performed in two other animals.

The single 4-hour, semi-occluded application of the test material to the intact skin of all three animals produced immediately after patch removal very slight erythema at the test site of one animal. This effect was gone at 24 hours after patch removal. Necrosis and ulceration were not reported.

The individual scores for each animal within 3 scoring times (24, 48 and 72 h) were 0.0/0.0/0.0 for erythema and 0.0/0.0/0.0 for oedema.

Under the test conditions, test substance is not classified according to the Annex VI of Regulation (EC) No. 1272/2008 (CLP) and to the GHS.

Interpretation of results:

Category 2B (mildly irritating to eyes) based on GHS criteria

Conclusions:

Under the test conditions, the test material is classified as H319 "Irritating to eyes" Category 2 according to the Annex VI of the Regulation (C) No. 1272/2008 (CLP) and as mild-irritant to the eyes (Cat. 2B) according to the GHS.

Executive summary:

In an eye irritation study performed according to the OECD Guideline No. 405 and in compliance with GLP, 0.1 mL of undiluted test material (Aqualenc F) was instilled into the left conjunctival sac of 3 male New Zealand White rabbits while the right eye served as control. The eyes were not rinsed after the instillation of test material. Animals were observed at 1, 24, 48 and 72 after instillation and then daily for 3 days. The reactions in the conjunctivae (redness, chemosis and discharge), the iris and the cornea (opacity and area involved) were scored according to the Draize Scale.

The calculated mean score for each individual lesion for all the animals within 3 scoring times (24, 48 and 72 h) were: 1.7 for redness, 0.8 for chemosis, 0.0 for iris lesions and corneal opacity.

The calculated mean score for each individual lesion for each individual animal within 3 scoring times (24, 48 and 72 hrs) were as follows: 0.7 / 0.7 / 1.00 for chemosis, 1.00 / 2.00 / 2.00 for redness, and 0.0 / 0.0 / 0.0 for iris lesions and for corneal opacity.

Very slight to slight conjunctival reactions were observed in all animals from day 1 up to days 4, 5 or 6. They were accompanied by a clear or purulent ocular discharge for 24 to 48 hours. No other ocular reactions were recorded.

Under the test conditions, the test material is classified as H319 "irritating to the eyes" Category 2 according to the annex VI of the Regulation EC No. 1272/2008 (CLP) and as mild-irritant to the eyes (Cat. 2B) according to the GHS.

Additional information

Skin irritation:

A key study was identified (Jouffrey, 1996). In this dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, 0.5 mL of Aqualenc F was applied on the clipped skin of 3 males New Zealand White rabbits.

An initial test was performed in one animal with exposure periods of 3 minutes and 4 hours. No cutaneous reactions were observed after an application of 3 minutes. A confirmatory is performed in two other animals.

The single 4 -hour, semi-occluded application of the test material to the intact skin of all three animals produced immediately after patch removal very slight erythema at the test site of one animal. This effect was gone at 24 hours after patch removal. Necrosis and ulceration were not reported.

The individual scores for each animal within 3 scoring times (24, 48 and 72 h) were 0.0/0.0/0.0 for erythema and 0.0/0.0/0.0 for oedema.

 

Eye irritation:

A key study was identified (Jouffrey, 1996). In this eye irritation study performed according to the OECD Guideline No. 405 and in compliance with GLP, 0.1 mL of undiluted test material (Aqualenc F) was instilled into the left conjunctival sac of 3 male New Zealand White rabbits while the right eye served as control. The eyes were not rinsed after the instillation of test material. Animals were observed at 1, 24, 48 and 72 after instillation and then daily for 3 days. The reactions in the conjunctivae (redness, chemosis and discharge), the iris and the cornea (opacity and area involved) were scored according to the Draize Scale.

The calculated mean score for each individual lesion for all the animals within 3 scoring times (24, 48 and 72 h) were: 1.7 for redness, 0.8 for chemosis, 0.0 for iris lesions and corneal opacity.

The calculated mean score for each individual lesion for each individual animal within 3 scoring times (24, 48 and 72 hrs) were as follows: 0.7 / 0.7 / 1.00 for chemosis, 1.00 / 2.00 / 2.00 for redness, and 0.0 / 0.0 / 0.0 for iris lesions and for corneal opacity.

Very slight to slight conjunctival reactions were observed in all animals from day 1 up to days 4, 5 or 6. They were accompanied by a clear or purulent ocular discharge for 24 to 48 hours. No other ocular reactions were recorded.

Justification for classification or non-classification

Harmonised classification

The substance has no harmonised classification according to the Regulation (EC) No. 1272/2008.

Self-classification

Based on the available data:

- no additional self-classification is proposed for the registered substance regarding skin irritation according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS

- the registered substance is classified as Category 2 (H319 "irritating to the eyes") according to the annex I of the Regulation EC No. 1272/2008 (CLP) and as mildly irritanting to the eyes (Cat. 2B) according to the GHS.

No data was available regarding respiratory irritation.
