Chemical free or chemical-free is a term used in marketing to imply that a product is safe, healthy or environmentally friendly because it only contains natural ingredients. The term is a misnomer, as nothing that physically exists in Earth's ecosystems is free of chemicals. The term "chemical" is roughly a synonym for matter, and common natural substances such as water and air are considered chemicals. This misuse of the term chemical in advertising and the tolerance of its misuse by the United Kingdom's Advertising Standards Authority have been the subject of criticism.
