General assessmentView source →

Cited by 180. The topical antiseptic agent triclocarban (TCC) is a common additive in many antimicrobial household consumables, including soaps and other personal care products. Long-term usage of the mass-produced compound and a lack of understanding of its fate during sewage treatment motivated the present mass balance analysis conducted at a typical U.S. activated sludge wastewater treatment plant featuring

Safety assessmentView source →

EPA ToxCast ER model: NO estrogen receptor activity found (AUC agonist=0, antagonist=0.000479). Tested in 18 in vitro assays. Caveat: this is an in vitro screening model with no dose or exposure context; it does NOT mean an effect occurs in humans at cosmetic use levels.
