Is Automotive Urea Harmful to the Human Body?

[VanBrianna]

Automotive urea is composed of 32.5% high-purity urea and 67.5% deionized water. Since the human body naturally produces urea, contact with the skin generally does not cause any harm. However, under high temperatures, automotive urea can easily release ammonia gas, which has corrosive properties. Prolonged skin exposure to ammonia may lead to pigmentation or ulcers. Below are the detailed explanations: 1. Under normal circumstances, automotive urea is harmless to the human body (if it comes into contact with the skin, simply rinse with plenty of soapy water or clean water, but avoid contact with eyes or ingestion). However, under high-temperature conditions, automotive urea may release ammonia gas (NH3); 2. NH3 can have corrosive and irritating effects on human skin tissue. Prolonged exposure to ammonia gas may result in symptoms such as skin pigmentation or ulcers. (If such symptoms occur, seek medical attention immediately to prevent more severe consequences).
