Triclosan TCS

SCA endorses products with the Allergy Certified logo, that contain 0.3% or less Triclosan (in accordance with Australian law). “FDA Finally Bans Toxic Triclosan from Antibacterial Hand Soaps. WASHINGTON – The federal Food and Drug Administration announced today that triclosan, a toxic chemical ingredient associated with hormone disruption in people, will no longer be allowed in antibacterial hand soaps, which EWG noted as a significant success.” -


Abbreviation TCS. CAS No: 3380-34-5. Triclosan is listed on Australia's TGA's Poisons Standard, for cosmetic use containing more than 0.3 per cent. Triclosan; "Synonym(s): 2,4,4'-TRICHLORO-2'-HYDROXY DIPHENYL ETHER; 5-CHLORO-2- (2,4-DICHLOROPHENOXY) - PHENOL; 5-CHLORO-2- (2,4-DICHLOROPHENOXY) PHENOL; PHENOL, 5-CHLORO-2- (2,4-DICHLOROPHENOXY) -; PHENOL, 5CHLORO2 (2,4DICHLOROPHENOXY) ; 2,4,4'-TRICHLORO-2'-HYDROXYDIPHENYL ETHER; 5-CHLORO-2- (2,4-DICHLOROPHENOXY) PHENOL; CH 3565; IRGASAN; IRGASAN DP300; PHENOL, 5-CHLORO-2- (2,4-DICHLOROPHENOXY)"EWG


Used in soap, personal care products, baby care and sanitisers. “Triclosan (TCS) is an antimicrobial used so ubiquitously that 75% of the U.S.A. population is likely exposed to this compound via consumer goods and personal care products. In September 2016, TCS was banned from soap products following the risk assessment by the U.S.A. Food and Drug Administration (FDA). However, TCS still remains, at high concentrations, in other personal care products such as toothpaste, mouthwash, hand sanitizer, and surgical soaps. Triclosan is readily absorbed into human skin and oral mucosa and found in various human tissues and fluids. The aim of this review was to describe TCS exposure routes and levels as well as metabolism and transformation processes. The burgeoning literature on human health effects associated with TCS exposure, such as reproductive problems was also summarized.” -



  • Known endocrine disruptor and skin irritant; especially thyroid and reproductive hormones. Studies raise concerns that triclosan contributes to making bacteria antibiotic-resistant. Tricolson can be found in toothpastes, antibacterial soaps and deodorants. Commonly used in baby care products including body wash, toothpaste and shampoo. SafeWork Australia's HSIS states "Toxic by inhalation (R23)"; "Irritating to eyes, respiratory system and skin (R36/37/38)"; "Very toxic to aquatic organisms (R50)"; and "May cause long-term adverse effects in the aquatic environment (R53)".
