This is not necessarily representative of all possible content that may be found in this product type. It includes all of the potential content identified during the research process for this Common Product profile. All Content data goes beyond the most common chemicals and materials to provide a more comprehensive representation of what may be found in specific product types. It does not necessarily include all chemicals and materials that may be used by all manufacturers and should not be used as a replacement for a specific manufacturer's product disclosure.

A Common Product profile (CP) is a list of substances that are most commonly present in a product type (vinyl composition tile, for example) as delivered to building sites in North America. The profiles are not specific to any manufacturer.

CPs are organized by chemical function. Every substance in a product performs some function - for example, it thickens a paint, or gives a carpet resistance to stains. The CPs provide the most common substance serving each function in a given product type, the hazards these substances carry into a building project, and a general description of the product type. CPs are based upon a wide range of publicly available information, including product declarations, patents, and chemical suppliers' brochures that detail the functional uses of various additives.

For those wanting more than the most common chemical for each function, Pharos subscriptions provide access to the full catalog of possible ingredients that we’ve found may be in products. Where available, these are displayed in the All Contents tab.
