Substances in chemical products or in articles
The prioritisation guide is based on having one substance that you want to know more about. The first step in the prioritisation guide is therefore to decide which substance you want to know more about. If you are starting from a chemical product or article, you must therefore first see which chemical substances it contains. You can get tips on how to identify the contents at Chemicals in practical use.
If you are starting from a chemical product the safety data sheet can give you more information about what substances may be contained in the product. Safety data sheets are not always complete. Ask your supplier for more information.
If you are starting from an article, you can get help from here to structure the job of finding out which chemical substances it may contain.
I know what substance I am interested in. I want to continue in the guide.
