Common products, including the ones labeled “green,” “all-natural,” “non-toxic,” and “organic,” emit a range of compounds that could harm human health and air quality, according to a new study. But most of these ingredients are not disclosed to consumers.
University of Melbourne Professor Anne Steinemann investigated and compared volatile organic compounds (VOCs) emitted from 37 different products, such as air fresheners, cleaning products, laundry supplies, and personal care products, including those with certifications and claims of “green” and “organic.”
She tested both fragranced and fragrance-free products.
The study, published in the journal Air Quality, Atmosphere & Health, found 156 different VOCs emitted from the 37 products, with an average of 15 VOCs per product. Of these 156 VOCs, 42 are classified as toxic or hazardous under US federal laws, and each product emitted at least one of these chemicals.
The findings reveal that emissions of these air pollutants from “green” fragranced products were not significantly different from regular fragranced products.
In total, over 550 volatile ingredients were emitted from these products, but fewer than three percent were disclosed on any product label or material safety data sheet (MSDS).
“The paradox is that most of our exposure to air pollutants occurs indoors and a primary source is consumer products. But the public lacks full and accurate information on the ingredients in these products. Our indoor air environments are essentially unregulated and unmonitored,” says Steinemann, a professor of civil engineering.
The most common chemicals in fragranced products were terpenes, which were not in fragrance-free versions. Terpenes readily react with ozone in the air to generate a range of additional pollutants, such as formaldehyde and ultrafine particles.
At this time, consumer products sold in Australia, the US, and around the world are not required to list all ingredients, or any ingredients in a chemical mixture called “fragrance.”
“Given the lack of information, consumers may choose products with claims such as green, natural, or organic, but those claims are largely untested,” says Steinemann.
