Formaldehyde 37%
Formaldehyde is an organic compound with the chemical formula CH2O and structure H−CHO, more precisely H2C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde. It is stored as aqueous solutions (formalin), which consists mainly of the hydrate CH2(OH)2. It is the simplest of the aldehydes (R−CHO). As a precursor to many other materials and chemical compounds, It is mainly used in the production of industrial resins, e.g., for particle board and coatings. Small amounts also occur naturally.

Formaldehyde (37% solution), commonly known as formalin, is used in various industries due to its strong disinfecting, preserving, and chemical reactivity properties. Here are the main industries where formaldehyde 37% is used:
- Chemical Manufacturing Industry
- Resin Production: Formaldehyde is a key ingredient in the production of resins such as urea-formaldehyde (UF), phenol-formaldehyde (PF), and melamine-formaldehyde (MF) resins. These resins are used in adhesives, particleboard, plywood, and laminates.
- Plastic and Polymer Industry: It is used in producing plastics such as polyoxymethylene (POM), which has applications in automotive parts, electrical components, and consumer goods.
- Textile Industry
- Fabric Treatment: Formaldehyde is used in textile finishing to improve wrinkle resistance, reduce shrinkage, and increase fabric durability. This process is common in the production of “permanent press” or “no-iron” fabrics.
- Wood Industry
- Wood Adhesives: Formaldehyde is a key component in the manufacture of adhesives used in engineered wood products like plywood, medium-density fiberboard (MDF), and particleboard.
- Wood Preservatives: Formaldehyde-based solutions are used to treat and preserve wood, protecting it from decay and insects.
- Healthcare and Medical Industry
- Disinfectant and Sterilant: Formaldehyde is used as a disinfectant in medical facilities for sterilizing medical instruments and equipment. Its strong biocidal properties make it effective in killing bacteria, viruses, and fungi.
- Preservative for Biological Specimens: Formaldehyde solution is widely used in laboratories and healthcare settings to preserve biological specimens (e.g., tissue samples, cadavers) for research and education.
- Pharmaceutical Industry
- Vaccine Production: In vaccine manufacturing, formaldehyde is used to inactivate viruses and toxins, making them safe for use in vaccines (e.g., inactivated polio vaccine).
- Antimicrobial Agent: It is used as an antimicrobial agent in various pharmaceutical products, including topical creams and disinfectants.
- Agriculture and Animal Husbandry
- Preservative for Animal Feed: Formaldehyde is used to preserve animal feed, especially fishmeal, by preventing microbial growth and spoilage.
- Fumigant: It can be used as a fumigant in agriculture to disinfect soil, greenhouses, and animal housing facilities.
- Cosmetic Industry
- Preservative in Cosmetics: Formaldehyde is used in low concentrations as a preservative in some cosmetic products, such as shampoos, nail polish, and hair straightening treatments, to prevent microbial contamination.
- Automotive Industry
- Production of Automotive Components: Formaldehyde resins are used in the production of high-performance automotive parts like coatings, brake pads, and molded components due to their heat resistance and durability.
- Paints, Coatings, and Varnish Industry
- Binder in Paints: Formaldehyde is used in the production of binders for paints, coatings, and varnishes, which helps enhance the durability, finish, and adherence of these products.
- Tanning and Leather Industry
- Leather Processing: In the leather tanning industry, formaldehyde is used to tan and preserve leather, improving its strength and resistance to wear and decay.
- Laboratory Use
- Tissue Fixative: Formaldehyde is commonly used in histology and pathology labs as a tissue fixative. It helps preserve tissue samples for examination under a microscope by preventing decay and preserving cellular structure.
- Construction Industry
- Insulation Materials: Urea-formaldehyde resins are used in the production of foam insulation and other building materials due to their insulating properties and structural strength.
In all these industries, formaldehyde 37% is valued for its chemical reactivity, preservative qualities, and ability to enhance the performance of other materials. However, due to its potential health hazards (such as being a known carcinogen), its use is strictly regulated, and handling requires proper safety measures.
