Holton et al., Characterization of asbestos exposures associated with the use of facial makeups. Risk Analysis, 42, 2129-2139

Holton and colleagues have performed a risk assessment after measuring asbestos released from several samples of facial makeup. Unfortunately, it is not possible to interpret or generalize their findings because the authors have not described the source(s) of the talc tested or the asbestos concentrations of the samples. The concentration of amphiboles varies widely between sources, and the authors are urged to divulge the locations of the ore bodies providing the talc for their samples, as well as the asbestos concentration of the samples, so that the results may be interpreted and possibly generalized.
