Hazardous Products Regulations

Marginal note:Data available for ingredients

• 8.2.11 (1) Subject to subsection (3), a mixture that contains one or more ingredients that are classified in the category “Skin Corrosion — Category 1” or the category “Skin Irritation — Category 2” is classified in a category or subcategory of this hazard class in accordance with subsection (2), subject to the following:

  • (a) ingredients that are classified in the category “Skin Corrosion — Category 1” or the category “Skin Irritation — Category 2” and are present in the mixture at a concentration equal to or greater than the concentration limit of 1.0% must be included in the calculation of the sum of concentrations of ingredients; and

  • (b) ingredients that are classified in the category “Skin Corrosion — Category 1” or the category “Skin Irritation — Category 2” and are present in the mixture at a concentration of less than the concentration limit of 1.0% must be included in the calculation of the sum of concentrations of ingredients only if there is evidence that, at the concentration at which they are present, the ingredients are skin-corrosive substances or skin-irritant substances.

• Marginal note:Classification — mixture

  (2) A mixture is classified in a category of this hazard class in accordance with the following:

  • (a) if the sum of concentrations of ingredients classified in the category “Skin Corrosion — Category 1” is equal to or greater than 5.0%, the mixture is classified in the category “Skin Corrosion — Category 1”;

  • (b) if the sum of concentrations of ingredients classified in the category “Skin Corrosion — Category 1” 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”, 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:

  Item	Column 1	Column 2	Column 3
  	Category	Ingredient	Concentration Limits
  1	Skin Corrosion — Category 1	Acid with pH ≤ 2	≥ 1.0%
  2	Skin Corrosion — Category 1	Base with pH ≥ 11.5	≥ 1.0%
  3	Skin Corrosion — Category 1	Other ingredients classified in the category “Skin Corrosion — Category 1”	≥ 1.0%
  4	Skin Irritation — Category 2	Other ingredients classified in the category “Skin Irritation — Category 2”, including acids and bases	≥ 3.0%
