Additional information
A GLP compliant acute dermal skin irritation/corrosion study in the rabbits was performed according to OECD guideline 404. 3 rabbits were treated on shaved skin with the test substance for 4 h and observation up to 72 h. No signs of irritation observed other than light blue staining of test site. The mean oedema and erythema score noted was 0.
A study similar to OECD guideline 404 performed with 6 rabbits, over all mean irritation score noted was 3 wherein the reactions were not fully reversible within 72 h. Primary irritation index score was 2.96. According to the results of this study the test substance is slightly irritating according to Federal Register 38, No 187. No labelling required according to EU guideline. It can be noted that abrasion on skin causes epidermal injury and further expected to cause the skin irritation and adverse effects to epidermis. This reaction could be referred to the damage caused due to abrasion rather than due to the test substance application. In general abrasion is an elevated testing condition and results normally do not have to be taken into account for hazard assessment. Hence, can be concluded as not irritating to rabbit skin.
In a Barail-Test intracutaneous injection of 0.02 ml of an aqueous solution with 0.01 %, 0.1 %, 1 %, 10 % test item concentration or physiological saline (control) were given to 3 rabbits. In addition, cutaneous administration of 0.5 ml of the 10 % preparation was applied to depilated flank skin of another 3 animals. The animals were observed up to 4 days. No irritation and other effects were observed. The overall mean irritation score was noted to be 0. Hence, test substance is determined as not irritating to rabbit skin.
Two other studies performed in the 1960ies and 1970ies reported the test substance as not irritating to rabbit skin.
Taking into consideration the results from the key study and other support studies the test substance can be determined to be not irritating to rabbit skin.
Eye Irritation:
Two acute eye irritation/corrosion studies were performed following procedure mentioned in Federal Register 38, No.178. Six rabbits were treated with the test substance for 24 h and observation up to 72 h. Maximum mean total score (MMTS) after 72 h was observed to be 0 and 1 on a scale of 110 respectively. Based on the score, the test substance is determined to be not irritation to eye.
Taking the results from the above mentioned studies into consideration, the test substance can be determined to be not irritating to rabbit eye.
Justification for selection of skin irritation / corrosion
endpoint:
Guideline study in compliance to GLP
Justification for selection of eye irritation endpoint:
Guideline similar to OECD.
Justification for classification or non-classification
Based on the finding in the skin and eye irritation studies, the test substance does not need to be classified according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
