The warning had been issued in Australia: the Friends of the Earth association stated that the “without nano-particles” claim on some sunscreens was misleading, when they contain zinc oxide available under the ZinClear IM 50CCT name. The association used, then, a study performed in cooperation with the Australian National Measurement Institute, which showed that, in the sunscreens that contain it, free nano-particles and aggregates are found.

As its first action (in August), it suspended its approval for this raw material, a protective measure while waiting for more information, especially the results of the analyses to check the presence of nano-particles in ZinClear.
Ecocert promised to release its conclusions within three weeks: it took a bit longer. In fact, until January, when the certifying body issued its communiqué for its customers, “Following a suspected presence of nano-particles in one of the zinc oxides it has approved, ZinClear IM 50 CCT, Ecocert has decided to conduct investigations on the raw material (analyses and a request for the opinion on the interpretation of the European definition of nano-materials in the Regulation on Cosmetics), in cooperation with Antaria, the manufacturer of …
