The PPG Restricted Substances List (RSL) establishes our current requirements for and restrictions on the use of certain hazardous substances in our products. PPG's RSL is based on the principle of addressing the health and environmental risks of substances that we use, produce and sell. We identify substances for inclusion on PPG's RSL based on international conventions, country-specific requirements and substance-specific information. When substances are added to PPG's RSL, a target date for restriction or prohibition is established and the affected businesses work to meet the requirements of the restriction prior to the target date. Progress towards the target date is tracked at least twice per year.
PPG's RSL applies to PPG products globally, including those sold in jurisdictions that do not have chemical regulation programs. PPG's RSL includes all substances covered by the Stockholm Convention on Persistent Organic Pollutants and industrial substances on the Rotterdam Convention Prior Informed Consent (PIC) list. Furthermore, PPG's RSL includes additional substances for which PPG has determined that restrictions are appropriate consistent with our values related to protection of human health and the environment. PPG's RSL program evaluates substances for addition to the list and regularly incorporates information about substances already on the list.
Some examples of substances that are restricted in PPG products globally are lead, benzene, and certain glycol ethers. Benzene can enter the supply chain as an impurity in naphtha solvents. However, as benzene is restricted in PPG products globally, high purity naphtha solvents that contain <0.1% benzene are used. High purity naphtha solvents include CAS 64741-66-8, 64742-49-0, 64742-48-9, 64742-95-6, 64742-82-1 and 8032-32-4. Another example of a substance on PPG's RSL is methylene chloride, which was added to the PPG RSL for restriction for all uses. Additionally, restrictions for some substances are appropriate for specific use scenarios, such as consumer uses.
