    “…This approach is illustrated with the marketing of sunscreens containing nano-sized titanium dioxide (TiO(2)) particles. We argue that the marketing of this TiO(2) nanomaterial in UV protective cosmetics is ethically undesirable, since it violates four reasonable moral conditions for societal experimentation (absence of alternatives, controllability, limited informed consent, and continuing evaluation). …”
