  Substance Attributes


  • 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.

  • Has known Side Effects

    This is often the result of long or short term medication use. The same medication can have a range of side effects ranging from none at all to totally debilitating symptoms within different individuals. Reasons for this include individual genetics, individual detoxification capacity, nutrition status, duration of use and total number of medications being taken.


    It becomes very difficult to establish clear causes of symptoms when multiple medications are being taken at once.

  • CATEGORIES: Medication or Drug | Household Toxin | Food Toxin | Synthetic Toxin | A Hazardous Substance that may be found in the Australian Workplace
  • SUBSTANCE LINEAGE: Organic Compounds | Organooxygen Compounds | Ethers | Diarylethers | Methoxyphenols and Derivatives
  • SYNONYMS: 2,4,4'-Trichloro-2'-hydroxydiphenyl ether | 5-chloro-2-(2 | 4-dichlorophenoxy)phenol | 5-Chloro-2-(2,4-dichloro-phenoxy)-phenol | DERMAPROT | Irgasan DP 30 | Stri-Dex cleansing bar | Triclosanum
  • DESCRIPTION: Triclosan is an antibacterial and antifungal agent. It is a polychloro phenoxy phenol. Though many consumer products contain triclosan, according to the Food and Drug Administration (FDA) at the present time there is no evidence that triclosan in personal care products provides an extra benefit to health beyond its anti-gingivitis effect in toothpaste. The FDA does not recommend changing consumer use of triclosan containing products one way or the other due to currently insufficient safety evidence. Studies by the Environmental Protection Agency (EPA) found triclosan to be an effective antibacterial. Triclosan safety is currently under review by the FDA and Health Canada.
  • COMMENTS:

    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.

  Health Associations

Mostly focused on Health Implications of Long Term Exposure to this substance

  • SYMPTOMS:
  • POSSIBLE HEALTH CONSEQUENCES: | Triclosan is prone to phase II metabolism via sulfotransferase and glucuronosyltransferase enzymes (Wang et al., 2004). In humans the resulting conjugates are excreted primarily in urine (Sandborgh-Englund et al., 2006). In one study, after in vivo topical application of a 64.5mM alcoholic solution of [(3)H]triclosan to rat skin, 12% radioactivity was recovered in the faeces, 8% in the carcass 1% in the urine, 30% in the stratum corneum and 26% was rinsed from the skin surface at 24 hours after application. (A7866) The terminal plasma half life of triclosan is 21 h (Sandborgh-Englund et al., 2006).
  • ACTION OF TOXIN: At in-use concentrations, triclosan acts as a biocide, with multiple cytoplasmic and membrane targets. At lower concentrations, however, triclosan appears bacteriostatic and is seen to target bacteria mainly by inhibiting fatty acid synthesis. Triclosan binds to bacterial enoyl-acyl carrier protein reductase enzyme (ENR), which is encoded by the gene FabI. This binding increases the enzyme's affinity for nicotinamide adenine dinucleotide (NAD+). This results in the formation of a stable ternary complex of ENR-NAD+-triclosan, which is unable to participate in fatty acid synthesis. Fatty acids are necessary for reproducing and building cell membranes. Humans do not have an ENR enzyme, and thus are not affected. |
  • TOXIN SITES OF ACTION IN CELL: "Membrane"
  • Additional Exposure Routes: Triclosan is used in a variety of common household products, including soaps, mouthwashes, dish detergents, toothpastes, deodorants, and hand sanitizers. It is also used in health care settings in surgical scrubs and personnel hand washes.
