Mixtures

A formula is not a chemical, so it needs its own arithmetic

A single-compound sheet is looked up. A mixture is calculated: each component's own CLP classification, weighted by its percent, against the concentration limits in CLP EC 1272/2008 Annex I. Declare the formula below and the Section 3 composition table and the finished-mixture draft label render with the clause behind every statement.

Formula

Declare the mixture

Enter each component, its percent w/w and the CLP classification printed on its own Section 3. The finished mixture is classified by CLP EC 1272/2008 Annex I summation.

Component 1

  • Eye Irrit. 2
  • STOT SE 3

Component 2

Component 3

Component 4

  • Skin Sens. 1

Declared total 100%

Awaiting a formula

The Section 3 component table and the finished-mixture label will render here. The example formula on the left is a real one — press Classify the mixture to see the summation, the Annex I clause behind every statement, and what the components could not decide.

What the summation does and does not cover

Health and environmental classes are summed: acute toxicity by the ATE mix calculation in Annex I 3.1.3.6, skin and eye effects by the additivity tables in 3.2.3 and 3.3.3, sensitisation, CMR, STOT and aspiration by their own generic limits, and aquatic hazard with M-factors under 4.1.3.

Physical hazards are not summable. Flammability, oxidising properties, gases under pressure and corrosivity to metals have to be measured on the finished mixture, or bridged from a tested mixture under Annex I 1.1.3. A mixture this page returns no flame pictogram for is not a non-flammable mixture, and the calculation says so on every result.
