"Formaldehyde 40% CP" refers to a solution of formaldehyde (CH2O) with a concentration of 40% and is designated as "CP," indicating its Commercial Grade purity. Formaldehyde is a chemical compound with the molecular formula CH2O, and it is a colorless gas with a pungent odor. In solutions, formaldehyde is commonly stabilized as formalin, which is a water solution of formaldehyde. Here are some key points about Formaldehyde 40% CP: Concentration: The "40%" indicates that the solution contains 40% formaldehyde by weight. This concentration is commonly used in various industrial applications. Commercial Grade (CP): "CP" stands for Commercial Grade, which means the formaldehyde solution is produced for commercial and industrial use. The purity level may vary, and it may contain impurities that are acceptable for certain applications but might not meet the standards for more specialized or sensitive uses. Stabilization: Formaldehyde is highly reactive and tends to polymerize. In commercial solutions like Formaldehyde 40%, stabilizing agents are added to prevent the formation of paraformaldehyde (polymerized formaldehyde) and to maintain the liquid state. Common Uses: Formaldehyde 40% CP has various industrial applications, including: Resin Production: It is a key component in the production of resins, such as urea-formaldehyde and phenol-formaldehyde resins, used in the manufacturing of wood products, laminates, and adhesives. Disinfectant: It is used as a disinfectant and preservative in certain laboratory and medical applications. Textile Industry: Formaldehyde-based resins are used in the textile industry for wrinkle-resistant finishes. Water Treatment: It may be used in water treatment processes. Safety Considerations: Formaldehyde is a strong irritant and a potential carcinogen. Proper safety precautions, including the use of personal protective equipment (PPE) and proper ventilation, are necessary when handling formaldehyde solutions.
