Extent: E+W+S+N.I.

If there are data showing that (an) ingredient(s) is/are corrosive or irritant to skin at a concentration of < 1 % (skin corrosive) or < 3 % (skin irritant), the mixture shall be classified accordingly.
Table 3.2.3
Generic concentration limits of ingredients classified as skin corrosion (Category 1, 1A, 1B or 1C)/skin irritation (Category 2) that trigger classification of the mixture as skin corrosion/skin irritation where the additivity approach applies
Sum of ingredients classified as:
Concentration triggering classification of a mixture as:
Skin corrosion
Skin irritation
Category 1 (see note below)
Category 2
Skin corrosion Sub-Category 1A, 1B, 1C or Category 1
≥ 5 %
≥ 1 % but < 5 %
Skin irritation Category 2
≥ 10 %
(10 × Skin corrosion Sub-Category 1A, 1B, 1C or Category 1) + Skin irritation Category 2
≥ 10 %
