Iso 22241 Certificate Diesel Exhaust Fluid For Technical Grade Urea Aus32 For Urea 46 Granular

Medical field
The dermatology department uses certain medicaments containing urea to increase the humidity of the skin. The sealing dressing used for non surgical nail removal contains 40% urea.
The C-14-breath test to test the presence of Helicobacter pylori used urea containing carbon-14 or C-13 markers. Because the urease of Helicobacter pylori uses urea to produce ammonia to increase the pH value in its surrounding stomach. The same principle can also be used to test similar bacteria living in animal stomachs.
Agricultural sector
Urea is a high concentration nitrogen fertilizer, which is a neutral quick acting fertilizer and can also be used to produce various composite fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects. Animal husbandry can be used as feed for ruminants. However, excessive temperature during granulation can produce a small amount of biuret, also known as biuret, which has an inhibitory effect on crops. China stipulates that the content of urea and biuret used in fertilizers should be less than 0.5%. When the urea content exceeds 1%, it cannot be used as seed fertilizer, seedling fertilizer, and foliar fertilizer. The urea content in other application periods should not be too high or too concentrated.
Industrial sector
It can be widely used as a raw material for the production of various products such as melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue Bx, monosodium glutamate, etc.
It has a brightening effect on chemical polishing of steel and stainless steel, and is used as a corrosion inhibitor in metal pickling, as well as in the preparation of palladium activation solution.
Application in cosmetics
Urea is a useful moisturizing ingredient that exists in the stratum corneum of the skin and is the main component of the natural moisturizing factor NMF. For the skin, urea has the effect of moisturizing and softening the stratum corneum, so it can also prevent the stratum corneum from blocking the pores, thereby improving the problem of acne. It is used to add moisturizing ingredients in facial mask, skin care lotion, cream, hand cream and other products. The addition ratio is 3-5%.
Laboratory Applications
Urea is very effective in denaturing proteins, especially in destroying non covalent bond bound proteins. This feature can improve the solubility of certain proteins, with a concentration of up to 10 moles per volume. Urea can also be used to manufacture urea nitrate.
