Formaldehyde is a chemical compound with the formula CH2O. It is a colorless gas with a pungent odor, but it is also available in solution form, known as formalin. Formaldehyde is used in various industries and applications, including:
Industrial Uses: It is utilized in the production of resins, such as urea-formaldehyde and phenol-formaldehyde resins, which have applications in manufacturing wood products, adhesives, and plastics.
Healthcare: Formaldehyde-based solutions, such as formalin, are used as a preservative for biological specimens in laboratories and pathology.
Cosmetics and Personal Care Products: Formaldehyde and formaldehyde-releasing agents are sometimes used as preservatives in cosmetics and personal care products, although their use is regulated due to potential sensitization and irritation.
Textiles: It can be employed as a finish or treatment for textiles to provide wrinkle resistance and durability.
Formaldehyde is known to have toxic properties and can cause health concerns, especially with long-term exposure or high concentrations. It is classified as a carcinogen by various regulatory bodies. Occupational exposure limits and safety regulations are in place to minimize the risks associated with formaldehyde in the workplace and consumer products.
