Shower gels, shampoos, perfumes, and other personal care products release chemicals into the air we breathe at home.
Indoor air quality is a critical topic, directly impacting our health and the environment. For decades, research has examined outdoor-to-indoor air exchanges, but we often overlook pollution generated right inside our homes.
Studies have highlighted emissions from candles and incense, yet the issue extends far wider. A February 2021 study in the journal Indoor Air, led by Amber Yeoman from the University of York (UK), revealed this broader scope. Yeoman discussed her findings in The Guardian on December 17, 2021.
Her team equipped a university bathroom with advanced monitoring devices and exhaust pipes to capture emissions. Volunteers used standard products: shampoo, shower gel, conditioner, moisturizer, facial cleanser, and deodorant spray.
Emissions varied by rinsing thoroughness—more rinsing meant fewer fumes. Key compounds detected included limonene (a reactive hydrocarbon), benzyl alcohol, and ethanol. The researchers emphasize the risks of accumulating indoor emissions and call for studies on their interactions. Notably, indoor pollution can surpass road traffic levels.
To curb this, manufacturers must take responsibility for product emissions. Banning aerosols, adding health and environmental impact labels, and creating quality certifications would empower consumers to make informed, responsible choices.
