Formaldehyde
Published in Kathleen Hess-Kosa, Indoor Air Quality, 2018
Beyond the previously mentioned airborne exposures, individuals inadvertently contribute to their own exposures by applying or using products that contain formaldehyde. Formaldehyde is used in cosmetics, shampoos, pharmaceutical products, medicines and vitamins, and perma-press clothing. If the container does not state the presence of formaldehyde, look for quaternium. Quaternium-15, a formaldehyde release agent, and similar preservatives (e.g., diazolidinyl urea) are found in conditioners, deodorant soaps, hairspray, styling mousse, fluoride toothpaste, mouthwash, mascara, hair coloring, and fingernail polish. See Table 13.2. These should be suspected when an individual has localized dermal complaints.
