Formaldehyde is an organic compound. As the simplest aldehyde, it is an important precursor to many other chemical compounds, especially for polymers. In view of its widespread use, toxicity and volatility, exposure to formaldehyde is a significant consideration for human health. Formaldehyde is a common building block for the synthesis of more complex compounds and materials. The textile industry uses formaldehyde-based resins as finishers to make fabrics crease-resistant. Formaldehyde-based materials are key to the manufacture of automobiles, and used to make components for the transmission, electrical system, engine block, door panels, axles and brake shoes.
