Ubiquitous in atmosphere and life forms . Providence VAMC Environmental, Safety & Health Department. What is Formaldehyde?. Formaldehyde is a colorless, strong-smelling gas commonly used as a preservative.. Although the term “formaldehyde” describes various mixtures of formaldehyde, water and alcohol, the term “formalin” describes aqueous solutions, particularly those containing 37 to 50% formaldehyde and 6 to 15 % alcohol stabilizer..
