Urea is widely used in agriculture as a nitrogen-rich fertilizer, promoting plant growth and improving crop yields. It is also utilized in the production of resins, adhesives, and plastics, particularly urea-formaldehyde resins, which are essential in manufacturing plywood and particleboard. In the cosmetics industry, urea acts as a moisturizer and skin conditioner, helping to soften and hydrate dry or rough skin. Additionally, it is employed in the pharmaceutical sector as a diuretic and in the treatment of certain skin conditions. In environmental applications, urea is used in selective catalytic reduction (SCR) systems to reduce nitrogen oxide emissions from diesel engines, contributing to cleaner air.
