What is Imidazolidinyl Urea?

Imidazolidinyl urea preservatives include diazolidinyl urea (bis(hydroxy)methyl imidazolidinyl urea, diazolidinyl urea), DMDMH hydantoin, and diazolidinyl urea releases formaldehyde at a higher concentration than DMDMH Hydantoin, so the risk of the former causing skin sensitization is also higher. Imidazolidinyl urea preservatives have been used for many years. The technology of each production brand is relatively mature, but because it can release formaldehyde, it is still relatively irritating to the skin. Therefore, these two preservatives are currently used in large quantities. In cleansing milk and other wash-off cosmetics, many old formulas use its complex with paraben esters as preservatives.

Imidazolidinyl Urea Preservative and its Application

Imidazolidinyl urea is a preservative in cosmetics. It has broad-spectrum antibacterial job, can hinder Gram-negative as well as desirable germs, as well as has a specific repressive effect on yeast in addition to mold and also mildew. It is mainly utilized to impede the recreation of germs. It can be made use of with The numerous parts in cosmetics work, as well as the test results program that its antibacterial capacity is not affected by surfactants, healthy proteins as well as various other unique ingredients in cosmetics.

Application: Imidazolidinyl urea can be made use of in lotions, hair shampoos, creams, conditioners as well as likewise various other items. It can be utilized alone or in combine with parabens as well as IPBC to boost its antibacterial impact.The usage variety of pH worth is 3 ~ 9, the general addition quantity is 0.2 ~ 0.4%, the optimum allowed enhancement quantity is 0.6%, and it can be included a vast temperature level variety (<90 ° C). Generally imidazolidinyl urea is combined with paraben or Kathon CG as an aesthetic chemical. It can be used in creams, milks, shampoos, and so on. It is especially ideal for some sophisticated nutritional cosmetics that are simple to be infected with P. aeruginosa when the pH worth is alkaline. The common dosage is 0.1% to 0.5%. Nonetheless, because imidazolidinyl urea can aggravate the skin of some people as well as quickly create allergic reactions, it is no more made use of in some high-end cosmetics.

Imidazolidinyl Urea Actions and Uses

1) Prepare a professional daily necessities biological antibacterial shower gel, which is composed of polysaccharide alginate, biological chitosan, Yujiexin, diazolidinyl urea, cocoamphodiacetate, sodium lauryl ether sulfate, dimethyl Silicone copolyol disodium sulfosuccinate, cocamidopropyl betaine and purified water are prepared by heating, dissolving and emulsifying in proportion. Alginate polysaccharides, biological chitosan, Yujiexin, and diazolidinyl urea have high activity, making the reaction products positively charged, so they are easily adsorbed by various bacteria and viruses that are usually negatively charged , thereby inhibiting and interfering with the enzyme system and splitting function of bacteria and viruses, and losing the reproductive function of bacteria and viruses. In addition, the film formed by polysaccharides and chitosan polymers blocks the respiratory channels of microorganisms, causing microorganisms to suffocate and die. die. Cocoamphodiacetate, Sodium Laureth Sulfate, Disodium Dimethicone Copolyol Sulfosuccinate, Cocamidopropyl Betaine and Alginate Polysaccharide, Chitosan, Yujiexin , Bi-imidazolidinyl urea bio-antibacterial shower gel has increased viscosity and becomes emulsion-like, and its pH is neutral, and a layer of colorless transparent film is formed on the surface after washing, which increases the long-term antibacterial effect and makes the surface detoxification Antibacterial effect is better. The present invention has the following advantages: it is suitable for disinfection and bathing of various skins; it has good antibacterial and disinfection bathing effect, low use concentration, good stability, low cost price, no damage to the skin, no pollution to the environment, and is suitable for various skins , biotechnology process, wide application and other characteristics

2) Prepare a Hongsen Sophora rooting agent, its composition includes naphthalene acetic acid, indole butyric acid, chitosan, diazolidinyl urea, super absorbent resin and fulvic acid; the weight of each part is: naphthalene acetic acid 10- 30 parts; 10-30 parts of indole butyric acid; 5-15 parts of chitosan; 2-7 parts of diazolidinyl urea; 6-20 parts of superabsorbent resin; 2-8 parts of fulvic acid; The rooting agent can not only promote the rooting of Sophora japonica cuttings, but also prevent dehydration of Sophora japonica, improving the quality of Sophora japonica and the survival rate of cuttings of Sophora japonica. Due to the high water-absorbing resin contained in the ratio, it can make the cuttings of Hongsen Sophora japonica not easy to dehydrate and improve the survival rate of cuttings.

3) Prepare an acne-removing lotion, including disodium edetate, deionized water, water-soluble jojoba oil, glycerin, triclosan, wheat germ extract, propylene glycol, hydrogenated castor oil, essence, witch hazel extract liquid, chamomile extract, guava fruit extract, dipotassium glycyrrhizinate, bis-imidazolidinyl urea, iodopropynyl butylcarbamate and allantoin. Production: (1) pour deionized water into the container, add disodium edetate; (2) add water-soluble jojoba oil and allantoin; (3) triclosan, diazolidinyl urea plus propylene glycol, iodo Add propynyl butyl carbamate; (4) mix hydrogenated castor oil and essence, pour glycerin; (5) cool down the material in step 2, pour wheat germ extract and dipotassium glycyrrhizinate into step 3, and mix the materials in step 4 Pour into; (6) witch hazel extract, chamomile extract, and guava fruit extract are added to the mixed material; (7) discharge. The invention does not irritate the skin and cause contact dermatitis, and does not reduce resistance.

4) Prepare a metal solder joint protectant. The steps are: 1) Weighing in parts by mass: dissolving sodium pyrophosphate, p-toluenesulfonic acid, benzotriazole, sodium hypophosphite and stearic acid in deionized water, heating while stirring; 2) Add strontium hydroxide and zeolite to the solution obtained in step 1), add sodium alginate during stirring, and heat the solution; 3) Add polydimethylsiloxane to the solution obtained in step 2) in sequence , dioctyl phthalate and bis-imidazolidinyl urea, stirring after adding the bis-imidazolidinyl urea to obtain a metal solder spot protectant. The protective agent prepared by the invention can have a good protective effect on the solder joints on the cold-rolled plate, and can form a protective layer on the surface of the cold-rolled plate to prevent the cold-rolled plate from being centered on the solder joint after spot welding Start to oxidize and corrode.

Characterization and Chemistry of Imidazolidinyl Urea and Diazolidinyl Urea

For years, the aesthetic chemicals imidazolidinyl urea (IU) as well as diazolidinyl urea (DU) have not just been poorly identified, but have actually likewise been appointed misleading chemical frameworks. The most typical brand name for IU as well as DU are Germall 115 and also Germall II, respectively. This magazine supplies understanding right into the structure as well as deterioration modes of these 2 popular contact irritants. About 30-40% of both items were defined by allantoin (synthetic resources), (4-hydroxymethyl-2,5-dioxo-imidazolin-4-yl)-urea (substance HU) and also most likely 1-( 3,4-bis-hydroxymethyl-2,5-dioxo-imidazolidin-4-yl)-1,3-bis-hydroxymethyl-urea (compound BHU). The complete chemical characterization of compound HU is revealed. The remainder of IU and DU were taken into consideration to be polymers of allantoin-formaldehyde condensation products. The logical approaches utilized to define IU and DU are capillary electrophoresis, NMR and mass spectrometry studies.
