Fragranced products have been linked to a variety of negative human health and societal effects in the general population, especially in sensitive sub-populations like asthmatics.
58% of individuals with asthma-like conditions, 76% with autism spectrum disorders, 82% with chemical sensitivity report adverse effects from fragranced products. Types of adverse health effects among the general population: 17% respiratory problems, 13% mucosal symptoms, 13% migraine headaches, 9% skin problems, 7% asthma attacks, 5% neurological problems, long-term risks include hormonal dysfunction from endocrine disruptors and cancer.
In a similar way to "secondhand smoke" from tobacco goods, extensive exposure to fragranced products leads to the problem of "secondhand scents", or unintended or involuntary contact to which the general population is exposed weekly.
In addition, fragranced items have been implicated as important contributors to outdoor air pollution, as their emissions travel outdoors from products used not only outdoors but also indoors.
Instead, a product may use the generic phrase "fragrance" (or another legally acceptable term like "perfume") to describe itself instead of all of the ingredients separately, although a product's "fragrance" is made up of tens to hundreds of compounds, with approximately 4,000 identified fragrance components.
In population-based research, however, all forms of fragranced items were linked to negative health impacts. As a result, a broad approach addressing a product category (fragranced products) could be beneficial (similar to smoke-free policies addressing tobacco products).
