Section 3 Composition/Ingredients

Substances

• Chemical name.
• Common name and synonyms.
• Chemical Abstracts Service (CAS) number and other unique identifiers.
• Impurities and stabilizing additives, which are themselves classified and which contribute to the classification of the chemical.

Mixtures

• Same information required for substances.
• The chemical name and concentration (i.e., exact percentage) of all ingredients which are classified as health hazards and are:
  • Present above their cut-off/concentration limits or
  • Present a health risk below the cut-off/concentration limits.
• The concentration (exact percentages) of each ingredient must be specified except concentration ranges may be used in the following situations:
  • A trade secret claim is made,
  • There is batch-to-batch variation, or
  • The SDS is used for a group of substantially similar mixtures.

Chemicals where a trade secret is claimed

• A statement that the specific chemical identity and/or exact percentage (concentration) of composition has been withheld as a trade secret is required.
