Formaldehyde Poisoning is a disorder brought about by breathing the fumes of formaldehyde. This can occur while working directly with formaldehyde, or using equipment cleaned with formaldehyde. Major symptoms may include eye, nose, and throat irritation; headaches; and/or skin rashes.
Formaldehyde in its pure form is a colorless gas. However, Formaldehyde gas is not used as a cosmetic ingredient. Instead, Formaldehyde may be dissolved in water and used as Formalin. Other ingredients that slowly release Formaldehyde may also be added to cosmetic and personal care products as preservatives.
