What are Common Products?

A Common Product Profile (CP) is a type of data record developed by the Healthy Building Network (HBN) that is not specific to any manufacturer but lists the substances that are most commonly present in a product type (vinyl composition tile, for example) as delivered to building sites in North America. These data records were originally developed as part of a collaboration called the Quartz Project, an open database of composition, health hazard, and environmental data for building products. The Quartz Project launched in 2015 with more than 100 CPs, which have been incorporated into Portico along with dozens more that HBN has developed since.

Every substance in a product is there because it performs some function - for example, it thickens a paint, or gives a carpet resistance to stains. The CPs include a list of the most common substances serving each function in a given product, the hazards these substances carry into a building project, and a general description of the product. CPs are based upon a wide range of publicly available information, from product declarations to patents to chemical suppliers' brochures that detail the functional uses of various additives. The CPs are intended to represent actual functional products, listing the commonly found content for each product type at the time of our research.

CPs in Portico are included as a reference for both manufacturers and project teams. They help identify possible gaps in a content inventory record where a function may be missing (such as a stain repellant or other additive). Please note that CPs do not represent a best case or worst case product formulation.
