Chemophobia

Chemophobia (or chemphobia or chemonoia) is an aversion to or prejudice against chemicals or chemistry. The phenomenon has been ascribed both to a reasonable concern over the potential adverse effects of synthetic chemicals, and to an irrational fear of these substances because of misconceptions about their potential for harm, particularly the possibility of certain exposures to some synthetic chemicals elevating an individual's risk of cancer. Consumer products with labels such as "natural" and "chemical-free" (the latter being impossible if taken literally, since all consumer products consist of chemical substances) appeal to chemophobic sentiments by offering consumers what appears to be a safer alternative (see appeal to nature).
