Almost 20% of the general population is sensitized to at least one allergen and fragrance is one of the most frequently cited substances causing reactions. Fragrance sensitivity is now seen in 1-4% of the general population, and 8-15% of people with contact dermatitis. According the the Dermatology Times, fragrances are most likely to cause allergic contact dermatitis. They account for 30-45% of reactions in cosmetic products.
A compound (a combination of two or more elements) made of volatile (evaporates at room temperature) chemicals that create an odor. Fragrances and perfumes are typically comprised of dozens or even hundreds of synthetic chemical compounds.
The manufacturers of fragrances and perfumes typically do not disclose the total composition of the fragrance for competitive reasons. The compounds in fragrances are typically of plant or animal origin. Without knowing the exact composition, it is impossible for a consumer to know if a product with fragrance contains an allergen of concern for them.
Scent is merely the presence of an aroma or smell. Fragrances and perfumes are chemical compounds that have a distinct smell or aroma.
Natural ingredients that have a scent such as Bisabolol (German Chamomile) or Anthemis Nobilis (Roman Chamomile) are not true fragrances. However, some people may be sensitized to these ingredients, and since they are clearly labeled they can be avoided.
Personal care products that are labeled “unscented” or “fragrance free” may still contain fragrance components, sometimes called masking fragrances. The purpose of masking fragrance is to cover up offensive odors that may naturally occur in a product. Some personal care products such as lotions and soaps are marketed as being “unscented” or “fragrance free” yet they contain herbal ingredients or oils from botanicals. These products may contain allergens such as rose oil, vanilla, and sweet almond oil.
