Additional information

Several in vivo guideline studies exist, that evaluate the skin irritating potential of the test substance. Only one was performed according to current OECD guideline 404 (BASF, 1986) and was therefore chosen as key study. Intact skin of 1 male and 2 female White Vienna rabbits was exposed to 0.5 mL of the test substance for four hours under semi-occlusive conditions. No erythema or edema were observed in any animal within the first 72 hours, and the study was terminated after 3 days.

 

In a study according to the USA/EPA/FIFRA guideline, subdivision F, Series 81 and GLP (BASF, 1994), 6 New Zealand White rabbits were treated with 0.5 mL of the test substance under occlusive conditions for 24 hours. Edema grade 1 was observed in one rabbit only. Erythema scores ranged from 0.5 to 3 (individual grades: 0.5, 1, 2.5, 2.5, 1.5, 3), half of which were not fully reversible within 72 hours.

 

In a similar study performed according to Federal Register 38, No 187, Paragraph 1500.41 and GLP (BASF 1997), also 6 New Zealand White rabbits were treated with 0.5 mL of the test substance for 24 hours under occlusive conditions. In this case, no edema were observed, and only 2 out of 6 rabbits showed erythema grade 0.5 (mean value from 24h, 48h, and 72h reading).

 

6 White Vienna rabbits were exposed to 0.5 mL of the test substance for 24 hours using occlusive conditions in an additional study according to Federal Register 38, No 187, Paragraph 1500.41 and GLP (BASF, 1984). All animals showed erythema between grade 1 and 2.6 (mean values from 24h, 48h, and 72h readings), and edema grade 0.3 (3 animals) or grade 2 (3 animals).

 

No eye irritation was observed in an in vivo study according to OECD 405 (BASF, 1986). 0.1 mL of the test substance was applied to the eyes of 2 male and 1 female White Vienna rabbit. All scores for iris, cornea, chemosis and conjunctival redness were 0, except for one rabbit which showed a mean value (24 - 72h) of 0.3 for conjunctival redness.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

Two out of four skin irritation studies, which were performed under harsh occlusive conditions, showed a slight irritating potential, which was just not sufficient for classification according to Regulation (EC) No 1272/2008. The other two studies, of which one was performed according to current OECD recommended conditions, while the other also used long-term occlusive exposure, showed no skin irritation. In addition, no eye irritating potential was observed. Based on these data, the substance is considered to be classified neither for skin nor for eye irritation under Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) 2019/521.
