The European Commission’s Scientific Committee on Consumer Safety has published preliminary opinions on phenylene bis-diphenyltriazine and styrene/acrylates copolymer nanospheres.

SCCS concluded that phenylene-bis-diphenyltriazine is safe for use as a UV filter in dermally-applied sunscreens, at concentrations of up to 5%. A conclusion could not be reached on its safety in products that might be inhaled, such as spray-on products. SCCS also expressed concerns over the presence of the impurities N-methyl-2-pyrrolidone (NMP) and hydrazine, both of which are classified as carcinogenic, mutagenic or toxic to reproduction, and are identified in the EU as substances of very high concern (SVHC). It was concluded that these should be kept at “trace levels” [in the final product].

With respect to the use of three styrene/acrylates copolymer nanospheres as encapsulating agents for dermally-applied slimming products, SCCS concluded that the submitted information (including on use and chemical identity) was insufficient to arrive at a conclusion on safety.


SCCS has also released an addendum to the existing opinion on zinc pyrithione (ZPT). After consideration of new data on the effects of ZPT on fertility and reproduction, SCCS concluded that the most critical effect was neurotoxicity, and that the point of departure (PoD) based on this endpoint was still the most sensitive. Therefore, the original conclusion was upheld, with ZPT considered safe when used in rinse-off hair care products at concentrations of up to 2%.
