Symptoms depend on each person's allergies and each<unk> 's or fragrance's ingredients. Symptoms may include allergic contact dermatitis, asthma attacks, headaches, and others. The most common allergic reactions to<unk>  or fragrances added to products is contact dermatitis, though other symptoms may occur, including allergic conjunctivitis. Patch test The diagnosis of the causal allergen is made by patch testing with a mixture of fragrance ingredients, the fragrance mix. This gives a positive patch-test reaction in about 10% of tested patients with eczema, and the most recent estimates show that 1.7–4.1% of the general population are sensitized to ingredients of the fragrance mix. Two studies show that inhalant-like allergies and sensitivity/intolerances are experienced by a subset of the US population, in the form of asthma and chemical sensitivities. Results aggregated from both surveys found that 30.5% of the general population reported scented products on others irritating, 19% reported adverse health effects from air fresheners, and 10.9% reported irritation by scented laundry products vented outside. Household products, such as soaps and detergents,<unk>  products, cosmetics, and other consumer goods, are estimated to use 2,500 different fragrance ingredients. Of those, approximately 100 different substances are known to elicit responses in at least some individuals. An estimated 1.7–4.1% of the general population shows a contact allergic response to a mix of common<unk>  ingredients. Although products can be labeled "fragrance-free", many still contain lesser-known fragrance chemicals that consumers may not recognize. Cinnamaldehyde (cinnamic aldehyde) is a common fragrance allergen.
