Metabolic Interference or Disruption
Interferes with human metabolism. This can be a very serious thing. Some of these interference mechanics are well established. However, often long term effects and health consequences remain largely unknown. Additionally an emerging area of concern and one that is not currently studied, is the combined synergistic effects these metabolically disrupting chemicals have on human health.
Metabolic interference happens when the substance produces highly reactive and often damaging intermediates during detoxification or when the substance binds to specific enzymes, important structural groups on molecules, receptors and membranes or targets DNA or mimics key nutrients.
Exposure Produces Health Symptoms
Symptoms maybe short term or long term depending on the exposure duration and intensity and effects areas like Cardiovascular, Gastrointestinal, Cognition, Fatigue. A substance with this attribute may cause an allergic skin reaction, serious eye irritation, allergy or asthma symptoms or breathing difficulties if inhaled.
These attributes are ONLY based on peer-reviewed evidence. See link to Data Sources below. Everyone benefits from knowing this stuff. Please Share.

- DESCRIPTION: 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. (L1890, L1894)
From Safe Work Australia and the Hazardous Substances Information System (HSIS) in Australia:
| | A Hazardous Substance that may be found in the Australian Workplace. Check with your employer or health and safety officer. Stay informed and become aware of the dangers that surround you. This chemical is included on the list of recognised hazardous chemicals from the Safe Work Australia - Hazardous Substances Information System (HSIS) that is based on the Globally Harmonised System of Classification and Labelling of Chemicals (GHS)
Work Health and Safety (WHS) Regulations are the basis for hazardous chemicals regulations in Commonwealth, State and Territory jurisdictions in Australia. Under the model WHS Regulations, manufacturers and importers of substances, mixtures and articles supplied for use in workplaces are required to determine whether they are hazardous to health and safety before supply. The model WHS Regulations mandate that the hazards of a chemical as determined by the Globally Harmonised System of Classification and Labelling of Chemicals (GHS) must be included in safety data sheets and on labels. There are transitional arrangements in place for moving to the GHS-based system.
The GHS Hazardous Chemical Information List contains chemicals classified by an authoritative source (such as the European Commission or NICNAS) in accordance with the Globally Harmonized System of Classification and Labelling of Chemicals (the GHS). This list contains the vast majority of chemicals currently in HSIS. This list and its detail are regularly updated by Work Safe Australia. The model Work Health and Safety (WHS) Regulations require chemicals to be classified in accordance with the Globally Harmonised System of Classification and Labelling of Chemicals (GHS). However transitional arrangements allow use of classification information in HSIS derived from the Approved Criteria until the 31 December 2016.

Mostly focused on Health Implications of Long Term Exposure to this substance
- SYMPTOMS: Some people have a contact allergy to imidazolidinyl urea, causing dermatitis. (L1894)
- POSSIBLE HEALTH CONSEQUENCES: Imidazolidinyl urea releases formaldehyde, a known human carcinogen. It may also react to produce nitrosamines, which are believed to be carcinogenic. (L962, L1890, L1894) | 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)
- ACTION OF TOXIN: 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.
