What is not a substance?
A mixture is a mix or solution of two or more substances. Under the EU chemicals legislation, mixtures are not considered substances.
When chemical compounds A and B are put together and do not react, this is not a substance but a mixture.
Mixtures can be:
- shampoos and soaps,
- other cosmetics,
- detergents, and
If you are producing or importing a mixture, you need to register each individual substance in your mixture if you produce or import it at one tonne or more per year.
If you are a formulator who mixes the individual substances to produce the mixture, you do not need to register each substance under REACH unless you are also a manufacturer or importer of the individual substances contained in the mixture.
You may use substances to produce things that have a special shape, surface or design. When the special shape, surface or design determines the function to a greater degree than the chemical composition, these are called articles under the legislation.
Chemical compounds A and B are put together and to produce an article.
Articles can be:
- pencils (crayons),
- T-shirts, and
If you are producing or importing an article, you need to register each individual substance in an article:
- if the substance is present in the article in quantities of over one tonne per year; and
- if the substance is intended to be released under normal conditions of use, for example a t-shirt containing a fragrance.
If the substance in your article has already been registered for the same use, you do not need to register it as well.
