It’s Not Just About VOCs: Select NPE-free Paint, Too
If you have been concerned about Volatile Organic Compounds (VOCs) in your paint , you should be equally concerned about nonylphenol ethoxylates (NPEs). In addition to specifying low- or zero-VOC paints to help protect human health and the environment, you should also include NPE-free paints in your specifications. Read on to find out why and see a list of products without NPEs.
Nonylphenol ethoxylates (NPEs) are commonly used surfactants  in acrylic paint. NPEs contain and break down into chemicals called nonylphenols, which are highly persistent, bioaccumulative, and toxic. Like halogenated flame retardants and stain repellents, these chemicals contaminate the food chain, exposing anyone, including people, in succession. Nonylphenols are lethal to fish and other aquatic organisms at very low concentrations. They are also suspected endocrine disruptors, which tend to affect children the most, but can affect us all. They sometimes mimic hormones, causing issues to a growing fetus and proper childhood development. According to the U.S. Environmental Protection Agency (EPA), nonylphenol has “been detected in human breast milk, blood, and urine and is associated with reproductive and developmental effects in rodents.”
To Select healthier paint, Healthy Building Network recommends that you:
(1.) Choose NPE-free Interior Paint
Benjamin Moore and Sherwin-Williams offer NPE-free paint in some of their standard product lines. There are likely other manufacturers who have eliminated NPEs. Ask your favorite paint supplier if they are in this group.
The estimated cost per 100 square feet for NPE-free paints are shown below. Cost per gallon of paint doesn’t always provide an accurate prediction of the total material cost because of variations in application. The cost provided here was calculated based on the cost per gallon, number of coats recommended, whether a primer is required, and the coverage range for a gallon of paint.

(2.) For color, specify colorants that do not add VOCs to paints
These colorants are standard for each of the NPE-free paints listed above.
Current Market Availability:
The above products were determined to be NPE-free from Health Product Declarations (HPDs) , manufacturer engagement, and the GS-11 database. The paint industry is rapidly changing its use of surfactants, and additional products may already be on the market.
Some of the Benjamin Moore paints have transparency documents: HPDs or Declare labels. These documents provide additional information on the products’ content and associated health hazards and are good steps toward full disclosure of product contents. The next step forward would be for all the content to be identified and screened down to 100 ppm.
The availability of NPE-free options in lower cost paints is a clear signal that major manufacturers in the U.S. are retooling production to use less toxic surfactants across their product lines. Home Depot is in the process of phasing out NPEs from their latex water-based paints sold in the U.S. and Canada. Globally, many paint ecolabel programs prohibit NPEs, but the only U.S. product certification that completely prohibits NPEs is Green Seal. Their GS-11 standard, used in the U.S. and abroad, has prohibited the use of NPE surfactants since 2010. However, Benjamin Moore’s Natura is currently the only Green Seal GS-11 certified interior acrylic latex paint sold in the U.S. If we all start specifying NPE-free paints, manufacturers will continue to respond and provide healthier, affordable options.

 VOCs released from the curing of wet applied products may not cause smog to form, but can pollute indoor air and harm human health in many ways. Health impacts range from headaches and dizziness to cancer and reproductive toxicity; most have not been fully studied. For more background on VOCs, see: CompAIR: HBN Launches New Tool For Comparing VOCs.
 The U.S. EPA explains, “NPEs are surface active agents (surfactants) that are part of the broader category of surfactants known as alkylphenol ethoxylates (APEs). NPEs represent approximately 80% to 85% of the volume of APEs.”
 All of these Benjamin Moore paints are stated to be “Zero VOC according to EPA Method 24.” Sherwin-Williams (SW) says its Harmony Interior Acrylic Latex is a “zero VOC formula.” SW reports that the other paints contain less than 50 grams per liter VOCs (less exempt solvents).
 Cost per gallon was obtained from the manufacturer website and/or stores. Per the product literature, Sherwin-Williams’ Harmony is the only paint on this list that requires a primer, and the cost of the primer is included in the cost per 100 square feet for this product. Note that costs may vary given project size and locale.
 Green Seal-11 (GS-11) is a standard and certification that requires paints and coatings meet certain environmental, health, and performance characteristics. See the Paint Hazard Spectrum on HomeFree for additional information.
 Health Product Declaration (HPD) - The HPD standard provides a framework for manufacturers to inventory and disclose the contents of their products and any associated human and environmental hazards. Through the standardized HPD form, manufacturers provide information on both intentional content and impurities within the product. The framework is maintained and updated by the Health Product Declaration Collaborative. Public HPDs can be found in the HPD Repository.
