Properties of urea
Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present.
Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm The melting point is 132.7. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 160 to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 , and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption.
Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces.
The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made.

When the temperature of urea is below 20 and the relative humidity is below 70%, it will not only not absorb moisture, but also evaporate water and reduce its water content; When the temperature exceeds 20 �¢?? and the relative humidity is higher than 80%, it starts to absorb moisture, and becomes paste when it is serious. When the air is dried again, it will re agglomerate, which is only inferior to ammonium nitrate. When the urea aqueous solution is at 80 �¢??, hydrolysis and decomposition reactions will occur, forming ammonium carbamate, ammonia gas and carbon dioxide respectively. Under acid and alkaline conditions, urea will decompose faster when it is heated. Urea is easy to combine with straight chain carbohydrates to form crystalline additional compounds; It forms a variety of double salts with various inorganic compounds, such as Ca (NO3) 2 �?�· 4CO (NH2) 2, NH4Cl �?�· CO (NH2) 2, CaChemicalbookSO4 �?�· 4CO (NH2) 2, MgSO4 �?�· 4CO (NH2) 2 �?�· 3H2O, Mg (NO3) �?�· 4CO (NH2) 2 �?�· 2H2O, etc; It is easy to form urea phosphate, dicalcium phosphate and water with monocalcium phosphate, namely Ca (H2PO4) 2 �?�· H2O+CO (NH2) 2 �¢?? H3PO4 �?�· CO (NH2) 2+CaHPO4+H2O; With nitric acid, it is easy to form urea nitrate, CO (NH2) 2+HNO3 �¢?? CO (NH2) 2 �?�· HNO3, which combines and relaxes the two; It can combine with formaldehyde to form urea formaldehyde compounds (uric acid rubber shrinks), in which the higher proportion of formaldehyde is urea resin, and the lower proportion is slow-release (effective) urea.
Urea is a raw material forthe manufacture of twomain classes of materials:urea-formaldehyde resins
and urea-melamine-formaldehyde used in marineplywood.

Urea is one kind of neutral fertilizer, which can be used in long time without any harmful material in soil. Usually it can be used both for base and top dressing fertilizer in agriculture. urea contains prilled urea and granular urea .
Prilled urea : gas based and coal based ; coated and uncoated; agriculture and industry grade
Granular urea : Can be used in agriculture and producing BB fertilizer and sulfur coated urea.
UREA is a spherical white solid. It is an organic amide molecule containing 46% nitrogen in the form of amine groups. UREA is infinitely soluble in water and is suitable for use as an agricultural and forestry fertilizer as well as for industrial applications which require a high quality nitrogen source.
Urea, known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. One of the simplest organic compounds is the main nitrogen-containing end product of protein metabolism in mammals and certain fish species. It is also the nitrogen fertilizer with the highest nitrogen content.

Applications
1.Medical field
Dermatology uses certain agents containing urea to increase the humidity of the skin. Non-surgical removal of nails uses occlusive dressings that contain 40% urea.
2.Agriculture
Urea is a highly concentrated nitrogen fertilizer, which is a neutral fast-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and there are no adverse effects after long-term application. Animal husbandry can be used as feed for ruminants. However, if the temperature is too high in granulation, a small amount of biuret will be produced, also known as biuret, which has an inhibitory effect on crops. China stipulates that the content of urea biuret for fertilizer should be less than 0.5%. When the content of biuret is more than 1%, it can not be used as seed fertilizer, seedling fertilizer and foliar fertilizer, and the urea content in other application periods should not be too much or too concentrated.
3.Industrial sector
It can be used in large quantities as a raw material for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue Bx, monosodium glutamate and other products.
4.Laboratory applications
Urea is very effective at denaturing proteins, especially non-covalently bonded proteins. This feature can improve the solubility of certain proteins at concentrations of up to 10 mol/volume. Urea can also be used to make urea nitrate.
GERMALL PLUS is a combination of Diazolidinyl Urea and IPBC pre-dissolved in Propylene Glycol for ease of use. This combination exhibits a synergistic preservative effect, which reduces the total active preservative level necessary; provides for complete, broad spectrum preservation against Gram-positive and Gram-negative bacteria, yeast, and mold.
Compatible with most cosmetic raw materials.
Can be used in a wide variety of leave-on and rinse-off personal care formulations for reliable preservation.
Recommended use levels in a finished formulation is 0.1-0.5%.
Add at 50�°C or below during the cool down stage of processing.
Every cosmetic formulation requires a specific preservative system to meet its individual needs. Therefore, every newly developed or modified product should be challenge tested to assure preservative efficacy.
