(a.2) if the sum of concentrations of ingredients classified in the subcategory “Skin Corrosion — Category 1B” is equal to or greater than 5.0%, and the mixture does not contain any ingredients classified in the category “Skin Corrosion — Category 1”, the subcategory “Skin Corrosion — Category 1A”, or the subcategory “Skin Corrosion — Category 1C”, the mixture is classified in the category “Skin Corrosion — Category 1” or the subcategory “Skin Corrosion — Category 1B”;
(a.3) if the sum of concentrations of ingredients classified in the subcategory “Skin Corrosion — Category 1C” is equal to or greater than 5.0%, and the mixture does not contain any ingredients classified in the category “Skin Corrosion — Category 1”, the subcategory “Skin Corrosion — Category 1A”, or the subcategory “Skin Corrosion — Category 1B”, the mixture is classified in the category “Skin Corrosion — Category 1” or the subcategory “Skin Corrosion — Category 1C”;
(a.4) if the sum of the concentrations of ingredients set out in two or more of the following subparagraphs is equal to or greater than 5.0%, the mixture is classified in the category “Skin Corrosion ─ Category 1”:
(i) ingredients classified in the category “Skin Corrosion ─ Category 1”,
(ii) ingredients classified in the subcategory “Skin Corrosion ─ Category 1A”,
(iii) ingredients classified in the subcategory “Skin Corrosion ─ Category 1B”, and
(iv) ingredients classified in the subcategory “Skin Corrosion ─ Category 1C”;
(b) if the sum of concentrations of ingredients classified in the category “Skin Corrosion — Category 1”, ingredients classified in the subcategory “Skin Corrosion — Category 1A”, ingredients classified in the subcategory “Skin Corrosion — Category 1B” and ingredients classified in the subcategory “Skin Corrosion — Category 1C” is equal to or greater than 1.0% but less than 5.0%, the mixture is classified in the category “Skin Irritation — Category 2”;
(c) if the sum of concentrations of ingredients classified in the category “Skin Irritation — Category 2” is equal to or greater than 10.0%, the mixture is classified in the category “Skin Irritation — Category 2”; or
(d) if the sum of the results of the following subparagraphs is equal to or greater than 10.0%, the mixture is classified in the category “Skin Irritation — Category 2”:
(i) 10 times the sum of concentrations of ingredients classified in the category “Skin Corrosion — Category 1”, ingredients classified in the subcategory “Skin Corrosion — Category 1A”, ingredients classified in the subcategory “Skin Corrosion — Category 1B” and ingredients classified in the subcategory “Skin Corrosion — Category 1C”, and
(ii) the sum of concentrations of ingredients classified in the category “Skin Irritation — Category 2”.
Marginal note:Mixtures containing particular ingredients
(3) A mixture is classified in a category of this hazard class in accordance with the following table if it contains one or more substances, such as acids, bases, inorganic salts, aldehydes, phenols or surfactants, which could be corrosive or irritant at concentrations below the concentration limits set out in subsection (2) and at least one ingredient with a concentration that is above the concentration limits set out below:
