What is Diazolidinyl Urea?

Diazoalkylurea is a new cosmetic chemical created by the American Sutton Firm in the 1980s. It has broad-spectrum anti-bacterial task. It not simply inhibits Gram-positive bacteria, microorganisms, yeasts, mold and molds and fungis, yet furthermore has distinct impacts on Gram-negative germs such as Pseudomonas aeruginosa and Escherichia coli. Within the dosage option There are no unsafe damaging results. Neither cationic, anionic or nonionic surfactants neither proteins affect the antibacterial job of diazoalkylurea. It works with primarily all aesthetic parts.

Diazolidinyl Urea Applications

1. Prepare a white wine yeast facial mask. The raw products and weight proportions in the formula are: 33 parts of white wine yeast, 8 parts of vitamin E-8, 11 parts of pearl powder, 3 parts of beer barley malt starch, and pyrrolidone. 7 parts of sodium carboxylate, 1.6 parts of Diazolidinyl Urea, 0.05 parts of plant important oil, 6 parts of polyvinyl alcohol, 2 parts of polyoxyethylene (20) sorbitan monolauryl ester, 2 parts of glycerol, and purified water included in 100 share. The dosage and physical and chemical residential properties of each raw material in today innovation generate a collaborating effect, therefore accomplishing the effects of free extreme scavenging and imperfection improvement. The PH value of the here and now invention is close to that of human skin and is non-irritating to the skin; after usage, the skin really feels clearly comfy, soft and non-greasy, and has apparent results of hydrating, lightening and repairing the skin.

2. Prepare a new kind of environmentally friendly printing ink. Made from the following resources by weight: 26-32 parts of vinyl chloride-acrylate copolymer material, 3-4 parts of methyl methacrylate, 3-9 parts of acrylic material, 4-7 parts of acetyl tri-n-butyl citrate parts, 10-13 parts of butyl octanol, 0.3-0.6 parts of 2-thiol benzimidazole, 0.4-0.7 parts of Diazolidinyl Urea, 1-4 parts of attapulgite, 0.6-0.9 parts of ammonium persulfate, 0.5 parts of chitosan -0.8 components, 2-3 parts of palm oil, 3-5 parts of organic pigments, 4-6 parts of additives, and proper quantity of water. It has the advantages of inexpensive, diversified features, antibacterial, heat resistance, high solidity, antibacterial, wear resistance, chemical corrosion resistance, fast drying out rate, and great printing versatility. The preparation method is simple, simple to run and extremely functional.

3. Prepare a kitchen wipes substance. It consists of the complying with products in weight percent: 30%-60% of eco-friendly solvent, 2%-4% of non-ionic surface task, 3%-8% of anionic surface task, 0.5%-2% of silicone defoaming representative, security Membrane layer 0.5%-2%, iodopropynyl n-butyl carbamate 0.05%-0.1%, Diazolidinyl Urea 0.05%-1%, 1,3 dihydroxymethyl-5,5 dimethyl hydantoin 0.05%- 1%, the rest is RO water. The preparation technique of the kitchen cleans compound fluid is likewise secured. The kitchen cleans prepared by the invention are environmentally friendly, very easy to biodegrade, have strong cleaning capability, no peculiar scent, less foam, no irritability, non-sticky feel, develop a protective layer on the hard surface, have anti-fouling homes, and are convenient for cleaning up following time benefit.

4. Prepare an eco-friendly deterioration and range prevention composition, computed by weight, including: 10-18 parts of customized polyepoxy succinic acid, 10-20 parts of acrylic acid copolymer, 5-12 parts of tannin, 20-30 parts Parts of salt silicate, 5-12 parts of salt D-gluconate, 10-20 parts of polydiene dimethyl ammonium chloride, 8-10 parts of zinc sulfate, 10-20 parts of Diazolidinyl Urea, 50-80 parts of detoxified water; Wherein, the changed polyepoxysuccinic acid is constructed from epoxysuccinate, 2-acrylamide-2-methylpropanesulfonic acid, and 3-prop-2-enoyloxypropane-1-potassium sulfonate. The acrylic copolymer is gotten by copolymerizing acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid and 2-acrylamide phenylboronic acid as monomers.

Diazolidinyl Urea Preparation

Utilizing 30% glyoxal as resources, the high-efficiency broad-spectrum preservative diazoalkylurea is prepared via oxidation response, cyclization response and hydroxymethylation reaction. Glyoxal was oxidized with nitric acid at 40 ° C for 4 hours, urea was contributed to the oxidation item and cyclized at 75 ° C for 3 hours, and the cyclized item allantoin and formaldehyde were reacted at reflux temperature for 1 hour. The overall synthesis return is 51%, and the nitrogen content of the product according to important analysis is 20.20%. The pureness of the item was established to be 99% by fluorescence spectroscopy.

Action 1: Preparation of allantoin. In a four-necked flask geared up with an electrical stirrer, condenser, consistent pressure going down funnel and thermostat, add 0.25 mol of glyoxal with a mass fraction of 30%, mix and raise the temperature to 40 ° C, add dropwise 0.20 mol of thin down nitric acid, 0.5 The addition is finished within h, and after an overall of 4 h of incubation response, a certain quantity of water is distilled out and delegated stand, and the precipitated oxalic acid is recouped as a byproduct. Include 0.8 mol urea to the filtrate, add combined acid catalysis under stirring, heat to 75 ° C, continue the reaction for 3 hours, then great, filter, laundry with water, and completely dry to obtain allantoin, return 52% (determined as glyoxal), melting point 236 ~ 237 ℃.

Step 2: Preparation of Diazolidinyl Urea. Add 0.2 mol allantoin and 0.8 mol formaldehyde service to a three-necked flask furnished with a stirrer and reflux condenser, warm, mix and reflux (80 ° C) for 1 hour, then change the reflux gadget to a vacuum purification device, heavy steam out the water, and completely dry Diazolidinyl Urea 54.8 g was gotten with a yield of 98%. Measured by fluorescence spectroscopy, its pureness is 99%.

Content Determination of Diazolidinyl Urea

Fluorescence spectrophotometer dimension: Diazoalkylurea decays due to the damage of the N-hydroxymethyl bond in ammonium acetate-acetate barrier solution and launches formaldehyde. The last goes through Hantzsch reaction with acetylacetone in the presence of ammonia to develop dihydropyridine derivatives:

Dihydropyridine derivatives have characteristic absorption at 410nm and fluorescence at 510nm. The material of diazoalkylurea can be quantitatively figured out by identifying the fluorescence intensity of dihydropyridine derivatives. The degree of bosom of the N-hydroxymethyl bond of diazoalkylurea is associated with the response problems. Under the conditions of this experiment, 2 N-hydroxymethyl bonds in each molecule of diazoalkylurea are damaged to launch two particles of formaldehyde.

The dimension steps are: consider 12.9 mg Diazolidinyl Urea right into a 100 ml volumetric flask, weaken it to quantity with (1 + 9) methanol, and after that dilute it 100 times with methanol liquid option to obtain an examination solution with a theoretical content of 1.29 μg/ ml. Take 4 ml of the test option, include an equivalent quantity of Nash’s reagent, react at 60 ° C for 1 hour, and then gauge the fluorescence intensity under the exact same conditions. The loved one fluorescence strength measured was 26.5.
