Justification for classification or non-classification
SKIN IRRITATION/CORROSION
A corrosive substance is a substance that produces destruction of skin tissue, namely, visible necrosis through the epidermis and into the dermis, in at least 1 tested animal after exposure up to 4 hour duration.
Three subcategories are provided within the corrosive category 1:
Subcategory 1A where responses are noted following up to 3 minutes exposure and up to 1 hour observation;
Subcategory 1B where responses are described following exposure between 3 minutes and 1 hour and observations up to 14 days;
Subcategory 1C where responses occur after exposures between 1 hour and 4 hours and observations up to 14 days
To classify a substance as irritant, the major criterion is that at least 2 of 3 tested animals have a mean score of ≥ 2,3 - ≤ 4,0.
Category 2:
- Mean value of ≥ 2,3 - ≤ 4,0 for erythema/ eschar or for oedema in at least 2 of 3 tested animals from gradings at 24, 48 and 72 hours after patch removal or, if reactions are delayed, from grades on 3 consecutive days after the onset of skin reactions; or
- Inflammation that persists to the end of the observation period normally 14 days in at least 2 animals, particularly taking into account alopecia (limited area), hyperkeratosis, hyperplasia, and scaling; or
- In some cases where there is pronounced variability of response among animals, with very definite positive effects related to chemical eposure in a single animal but less than the criteria above.
EYE IRRITATION
Serious eye damage means the production of tissue damage in the eye, or serious physical decay of vision, following application of a test substance to the anterior surface of the eye, which is not fully reversible within 21 days of application.
Eye irritation means the production of changes in the eye following the application of test substance to the anterior surface of the eye, which are fully reversible within 21 days of application.
Irreversible effects on the eye (Category 1):
If, when applied to the eye of an animal, a substance produces:
- at least in one animal effects on the cornea, iris or conjunctiva that are not expected to reverse or have not fully reversed within an observation period of normally 21 days; and/ or
- at least in 2 of 3 tested animals, a positive response of corneal opacity ≥ 3 and/or iritis > 1,5 calculated as the mean scores following grading at 24, 48 and 72 hours after installation of the test material.
These observations include animals with grade 4 cornea lesions and other severe reactions (e.g., destruction of cornea) observed at any time during the test, as well as persistent corneal opacity, discoloration of the cornea by a dye substance, adhesion, pannus, and interference with the function of the iris or other effects that impair sight. In this context, persistent lesions are considered those which are not fully reversible within an observation period of normally 21 days. Substances are also classified in Category 1 if they fulfil the criteria of corneal opacity ≥ 3 or iritis > 1,5 detected in a Draize eye test with rabbits, recognising that such severe lesions usually do not reverse within a 21-day observation period.
The substance does not meet the requirements to be classified in Category 1.
Irritating to eyes (Category 2)
when applied to the eye of an animal, a substance produces:
- at least in 2 of 3 tested animals, a positive response of: corneal opacity ≥ 1 and/or iritis ≥ 1, and/or conjunctival redness ≥ 2 and/or conjunctival oedema (chemosis) ≥ 2
calculated as the mean scores following grading at 24, 48 and 72 hours after installation of the test material, and which fully reverses within an observation period of 21 days.
Based on the results obtained in the skin and eye irritation studies, the test substance does not need to be classified for skin and eye irritation according to the CLP Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
