Fragrance free or unscented does not guarantee they do not contain fragrance chemicals: they imply they have no perceptible odor. A product labeled “unscented” may contain a masking fragrance. If fragrance is added to a product to mask or cover up the odor of other ingredients, it is not required to be put on the label. A product must be marked “without perfume” to indicate that no fragrance has been added. Ninety-five percent of the chemicals used in fragrances are petroleum-based synthetic compounds. Here are some principal chemicals found in scented products and the health risks that can be involved:
{“Fragrance Sensitivity,” allergies.about.com - Sep. 2001}
- Acetone — when inhaled, it can cause mild central nervous system disturbances such as dizziness, nausea, lack of coordination, slurred speech, and drowsiness. It can irritate the eyes, nose, throat, and skin.
- Alpha-pinene — can be a moderate irritant to skin, eyes, and mucus membranes.
- Alpha-terpineol — can cause excitement, loss of muscular coordination, hypothermia, central nervous system and respiratory depression, and headache.
- Benzyl acetate, benzyl alcohol, benzaldehyde, camphor, ethanol, and others. Most fragrance chemicals are not tested for safety.
