Fragrant essential oils, derived from plants, may release various VOCs into the air. VOC degradation caused by the reaction of these compounds with ozone present in the air can produce small, ultrafine byproducts called secondary organic aerosols (SOAs), which may cause eye and airway irritation.
Taiwanese researchers tested essential oils for SOA formation in a controlled-environment study chamber. They also performed air sampling and analysis in spa centers that offer massage therapy using essential oils.
In the paper "Characteristics of Air Pollutants and Assessment of Potential Exposure in Spa Centers during Aromatherapy." They conclude that the layout and ventilation within a particular spa may affect the level of indoor air pollutants produced during massage with aromatherapy.
