What is blending
Blending is commonly described as the process of mixing two or more chemicals together without producing a chemical reaction or creating more industrial chemicals as a result. Many consumer and cosmetic products containing industrial chemicals are mixtures formed by blending.
You don’t need to be registered with us to blend industrial chemicals, as long as the ingredients are purchased from an Australian supplier.
If a chemical reaction does occur and more industrial chemicals are created as a result, it’s defined as manufacturing. You must register with us to manufacture industrial chemicals.
And if you import industrial chemicals or products that release industrial chemicals from overseas for commercial blending in Australia, then you must register with us.
Consumer and cosmetic products that are mixtures of industrial chemicals still need to comply with other Australian legal requirements for labelling and consumer safety.
Examples of blending industrial chemicals
- Mixing pigments or inks
- Making soaps using the melt-and-pour method with a pre-made base
- Mixing cosmetics such as moisturisers, fragrances or essential oils using Australian-sourced ingredients
- Cold emulsifying (mixing using a mechanical process that does not produce a chemical reaction)
What is manufacturing
If you mix industrial chemicals (or products containing chemicals) together and it results in a chemical reaction that produces more industrial chemicals, then this is defined as manufacturing under the Industrial Chemicals Act 2019. If your manufacturing is for a commercial purpose, then you must register with us.
Examples of manufacturing chemicals
- Making soap via saponification of fats or oils using lye (sodium hydroxide)
- Creating essential oils using steam distillation or solvent extraction
- Macrylic polymers (commonly used in nail polish, paints and adhesives) through the process of polymerisation
