    • The ABC 7.30 Report recently (18 th December 2008) ran a story on the possible “dangers” of sunscreens containing nano-sized particles of zinc oxide or titanium dioxide. Zinc oxide is the basic ingredient of zinc cream which has been used for decades to treat and prevent nappy rash (zinc and castor …
