Compound Groups

Compound groups are groups of chemicals that share structural or chemical features. In most cases, hazard lists will assign hazards to individual substances. Compound groups are useful because in some cases, lists will instead identify a group of structurally similar compounds (such as lead compounds) as all having the same hazard. The Pharos staff is in the process of establishing and populating compound groups, and associating warnings from the hazard lists with them. The table below indicates how each compound group is populated, and what is the status of its population.

Antimicrobials incomplete

The term “antimicrobials” is a general term to describe a variety of substances that kill or control the growth of microbes, including bacteria and fungi.

These substances are regulated as pesticides by the US Environmental Protection Agency and can present hazards to human and/or environmental health.

A great number of products on the market incorporate antimicrobials into their composition because they require preservation.  Water-based formulations and certain polymers are vulnerable to microbes that would otherwise feed on these materials and over time compromise their performance or appearance.

Some products on the market may include antimicrobials not for preservation, but to kill microbes that might make us sick.  However, to date there is no evidence that adding antimicrobials these products result in healthier populations, and the Centers for Disease Control & Prevention (CDC) and Food and Drug Administration (FDA) have both issued statements advising that adding antimicrobials to such products are unnecessary.

The inclusion of antimicrobials in finished products – especially when used as preservatives – is not always disclosed and it may be difficult to determine what additives are present, and in what amounts.

This is a partial list of antimicrobial additives that may be present in building products as identified by Healthy Building Network in 2016.
