Additional information

The analogue substance was tested for skin and eye irritation following EU Method B4 and B5 respectively (NON dossier, 1991). In vivo results are available showing no irritating potential for skin and eye.

Based on the read across considerations the same results apply to Direct Blue 267:1

Justification for classification or non-classification

Under Regulation 1272/2008:

a substance is classified as skin irritant Cat 2:

1) 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

2)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

3) In some cases where there is pronounced variability of response among animals, with very definite positive effects related to chemical exposure in a single animal but less than the criteria above.


A substance is classified as:

Eye irritant Cat 2: if at least in 2 of 3 tested animals, a positive response of:

1)    corneal opacity ≥ 1 and/or

2)    2) iritis ≥ 1, and/or

3)     conjunctival redness ≥ 2 and/or

4)     conjunctival oedema (chemosis) ≥ 2

5)    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 of the in vivo studies performed on the analogue substance and the read across considerations, the substance is not classified for skin and eye irritation
