Metabolism / Metabolites
Formaldehyde may be absorbed following inhalation, oral, or dermal exposure. It is an essential metabolic intermediate in all cells and is produced during the normal metabolism of serine, glycine, methionine, and choline and also by the demethylation of N-, S-, and O-methyl compounds. Exogenous formaldehyde is metabolized to formate by the enzyme formaldehyde dehydrogenase at the initial site of contact. After oxidation of formaldehyde to formate, the carbon atom is further oxidized to carbon dioxide or incorporated into purines, thymidine, and amino acids via tetrahydrofolatedependent one-carbon biosynthetic pathways. Formaldehyde is not stored in the body and is excreted in the urine (primarily as formic acid), incorporated into other cellular molecules, or exhaled as carbon dioxide. Nitrosamines can also enter the body via ingestion, inhalation, or dermal contact. Once in the body, nitrosamines are metabolized by cytochrome P-450 enzymes, which essentially activates them into carcinogens. (L962, A2878, A2879) |

| Toxicity/Toxicokinetics |
Toxicity Summary
Imidazolidinyl urea is a formaldehyde releaser. It is likely that formaldehyde toxicity occurs when intracellular levels saturate formaldehyde dehydrogenase activity, allowing the unmetabolized intact molecule to exert its effects. Formaldehyde is known to form cross links between protein and DNA and undergo metabolic incorporation into macromolecules (DNA, RNA, and proteins). Imidazolidinyl urea is also a nitrosating agent. Nitrosating agents may decompose and/or react to cause nitrosamine contamination. Nitrosamines are produced from secondary amines and amides in the presence of nitrite ions and are believed to be carcinogenic. Once in the body, nitrosamines are activated by cytochrome P-450 enzymes. They are then believed to induce their carcinogenic effects by forming DNA adducts at the N- and O-atoms.

| Additional Infomation |
Imidurea is a member of ureas. It has a role as an antimicrobial agent.
Imidurea is an antimicrobial preservative used in cosmetics. It acts as a formaldehyde releaser. Imidurea is a Standardized Chemical Allergen. The physiologic effect of imidurea is by means of Increased Histamine Release, and Cell-mediated Immunity. Imidazolidinyl urea is an antimicrobial preservative used in cosmetics. It acts as a formaldehyde releaser. Imidazolidinyl urea may cause contact dermatitis. It's toxicity is also due to it's ability to react and release formaldehyde and nitrosamines, both of which are believed to be carcinogenic.

Solubility in Formulation 1: ≥ 2.5 mg/mL (6.44 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.44 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
