Formalin is a solution of formaldehyde gas dissolved in water. Formaldehyde is a colorless, strong-smelling gas that is commonly used in a liquid form, as formalin, for various industrial applications. Here are some key points about formalin: Chemical Composition: Formalin is typically a 37% aqueous (water-based) solution of formaldehyde. The remaining percentage is water. Uses: Preservation: Formalin is widely used as a preservative for biological specimens. It helps to prevent decay and decomposition, making it essential in laboratories, museums, and medical facilities for preserving tissues and specimens. Disinfectant: It has antimicrobial properties, and as such, formalin solutions are sometimes used as disinfectants and biocides. Textile Industry: Formalin can be used in the textile industry for wrinkle-resistant finishes on fabrics. Health and Safety Concerns: Formalin is a strong irritant and can be harmful if inhaled, ingested, or comes into contact with the skin. Prolonged or repeated exposure to formaldehyde can cause respiratory irritation and may be associated with certain health risks. Proper ventilation and personal protective equipment are recommended when working with formalin. Regulation: Due to its potential health risks, the use and handling of formalin are subject to regulations and guidelines in many countries. These regulations aim to ensure safe practices and protect workers and the environment.
