That Formaldehyde. The stuff they use to preserve biological specimens in science labs. It is in some people's skincare.Its function in cosmetics is as a disinfectant, germicide, fungicide, and preservative. It shows up in deodorant, nail polish, soap, shampoo, and shaving cream. Canada restricts it. The European Union has banned it. It is on virtually every serious hazardous chemicals list in existence.The health picture is extensive. Formaldehyde is an immune system, respiratory, hematological, and skin toxicant. It is a probable carcinogen and cardiovascular toxicant. It can damage DNA. It may trigger asthma. Animal studies show sense organ, brain, and nervous system effects. It is a possible human developmental toxicant.The fact that this ingredient exists in personal care products at all is one of the most compelling arguments for why we built the Dirty Thirty list. At Keys, it's been on our no-use list since day one. Visit KeysPure.com to learn more about our formulation philosophy.Episode Twelve of the Dirty Thirty. Formaldehyde — it belongs in a lab jar, not your medicine cabinet.
