Urea 46 fertilizer, also known as carbamide,, is a nitrogen-rich fertilizer with 46% nitrogen content by weight. Widely used in agriculture, it promotes plant growth and crop yield by providing a concentrated source of essential nitrogen. Urea 46 is typically applied as granules to soil, where it undergoes conversion into plant-available nitrogen forms. While cost-effective and efficient, proper application techniques are important to manage potential nitrogen loss and environmental impacts.urea is also employed in the manufacture of paints, glues, plastics, paper, textiles, feed and weed control chemicals as well as a source of non-protein nitrogen.

1. Urea is a very good moisturizing ingredient. It is found in the stratum corneum of the skin and is a major component of the skin’s natural moisturizing factor NMF. For the skin, urea has moisturizing and soft keratin, so it can prevent the stratum corneum from blocking the pores, thereby improving the problem of acne. It is used to add moisturizing ingredients to masks, skin care lotions, creams, hand creams and other products. The addition ratio is 3-5%.
2. Industrial applications: It has a light-increasing effect on chemical polishing of steel and stainless steel, as a corrosion inhibitor in metal pickling, and also as a preparation for palladium activation liquid.
3. Urea is a high concentration of nitrogen fertilizer, is a neutral organic fertilizer, also can be used in the production of a variety of compound fertilizer.
