Generally, as a possible way to solve the problem of POM photostabilization, a series of ultraviolet (UV) stabilizers have been successfully used to prevent polymeric materials from aging induced by sunlight, such as benzophenones, benzotriazoles, triazines, and hindered amine light stabilizers.
For example, certain benzophenones, dichlorophenols, parabens, and the compound triclosan have been shown to disrupt estrogen receptor signaling in animal and in vitro models either by binding directly to the receptor itself or through modulation of downstream signaling processes (Akahori et al.
