If fragrances and the products they are added to didn’t contain so many seriously harmful ingredients which pollute the air we all breathe, the clothing we wear, the water we drink, and the soil we grow the foods we eat in, there wouldn’t be a need to go fragrance-free. Strangely, the fragrance industry has seen fit to include a vast array of toxic, petrochemical pollutants and highly allergenic substances in their products.
Here are some resources to use in making schools, workplaces and homes safer places to be. Some are new, some I’ve already linked to in other places on this site.
Hope you find them helpful.

The CDC Indoor Environmental Quality Policy from 2009 explicitly states:
“Fragrance is not appropriate for a professional work environment, and the use of some products with fragrance may be detrimental to the health of workers with chemical sensitivities, allergies, asthma, and chronic headaches/migraines.” …
Potential hazards include chemicals, biological agents, fragrant products, and physical conditions that may cause irritation, illness, or exacerbate existing health conditions” …
