Tricolsan is a preservative and anti-bacterial agent and a hidden chemical in personal care. It is widely used in antiperspirants, deodorants, cleansers, and hand sanitizers, and as an anti-bacterial agent in laundry detergent, facial tissues, and antiseptic.
- hand sanitizer
- laundry detergent
WHAT TO LOOK FOR:
Triclosan (TSC) and triclocarban (TCC)
Endocrine Disruption: Evidence suggests that tricolsan is an endocrine disruptor and impacts thyroid function and thyroid homeostasis (1) (2)
Tricolsan-resistant bacteria: There is mounting evidence that suggests the use of tricolsan promotes bacteria that are resistant to antibiotic medications and antibacterial products (3)(4). A 2010 study by the European Commissions Scientific Committee on Consumer Safety determined that low concentrations of triclosan can encourage the growth of antimicrobial drug-resistant bacteria.
Bioaccumulation / Environmental Toxicity: Triclosan accumulates in fatty tissue, and has been found in human milk samples (5) as well as the umbilical cord blood of infants (6). Triclosan and triclocarban are more likely to kill algae, crustaceans and fish than they are microbes (7). Due to the extensive use of triclosan, these chemicals often ends up in sewage systems, and non agricultural settings, which can lead to exposure to plants, soil-dwelling biota, and their predators (8)
TIP: The FDA found no evidence that anti-bacterial washes containing triclsan are any more effective at protecting against bacteria than regular soap and water (9).
