The Signal: News and Notes from the Pharos Team
One might think that an unfinished wood floor is devoid of synthetic chemicals. It sure looks that way--but toxic preservatives may lie in plain sight.
Moist lumber is susceptible to fungal staining. This staining does not cause physical decay, but it looks bad. Commonly called "blue stain," the offending fungi may be yellow, orange, purple, gray, or red in addition to shades of blue. The stain penetrates into the sapwood and cannot be removed by resurfacing.
Lumber mills can prevent these blemishes without chemical treatment through standard air-drying practices or, especially in moist climates, kiln drying.
However, a lot of lumber is treated with biocides called anti-sapstain treatments. While preventing visible blemishes, these can disfigure the toxicological profile of an otherwise benign product.
What is this stuff?
Anti-sapstain formulations have been used for millennia. Egyptians used...
DENVER -- Polycarbonate made without bisphenol-A. Eliminating formaldehyde-based binders in laminates and particleboard. Producing chemical building blocks, like ethylene and butanol, from agriculture, not petrochemicals. Transparency in material content disclosure.
These ideas would be expected in a green chemistry symposium. But these were workshop topics at this week’s spring convention of the Adhesive and Sealant Council (ASC). Ideas about how to achieve sustainable production through reformulations dominated the discussions.
The meeting of big-time raw material suppliers and formulators left me feeling that we have reached an inflection point. Environmental and human health considerations have shifted from the realms of theory and advocacy into innovative application.
This transformation in...
Every organization has its shorthand, and here at the Pharos Project our Chemical and Material Library (CML) is affectionately referred to in-house as “the camel.” Not unlike its mammalian cousin, the CML serves as a valuable resource for chemical intelligence in what can sometimes feel like an informational desert. The CML screens 22,000 chemicals, materials, and biobased ingredients against more than 40 authoritative lists of health and environmental warnings to provide users with a summary of expected direct health and environmental hazards, and a breakdown of hazards associated with each substance’s life cycle.
With the launch of Pharos version 2 (v2), the CML has been rebuilt and relaunched with faster searches, more chemical information, and new features to improve the user experience.
Pharos now tracks twice as many health and environmental endpoints as it used to, informed in part by the ...

When building products carry different green certifications, how do you know which product is best? Maybe there is a way to compare apples and oranges.
As green certifications and labels have proliferated, so has greenwash. Even among legitimate certifications, conflicts and inconsistency have made them hard to understand.
How do you cut through the cacophony and get the information you want? The Pharos Project has independently organized information on about 48 major product certifications and products that carry those labels.
Start by finding products
If you want products certified to a...
