July 20, 2018 - PRLog -- On June 20, 2018, the European Union (EU) authorized the use of the nano form of 2,2′-Methylene-bis(6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethyl-butyl)phenol)/Bisoctrizole (Methylene Bis-Benzotriazolyl Tetramethylbutylphenol or MBBT0 as a UV filter, with restricted applications, in cosmetic products.

The decision follows opinion SCCS/1546/15 of the Scientific Committee on Consumer Safety (SCCS), which advised the safe use level for MBBT (nano). Until now, the non-nano form of MBBT has been permitted for use in cosmetic products as a UV filter with a maximum authorized level of 10%.

The regulation change means the nano form of MBBT is also permitted to a maximum authorized level of 10%. It cannot, however, be used in applications where there is a risk of exposure of the end user's lungs by inhalation. Also, only nanomaterials having the following characteristics are allowed:

·         Purity ≥ 98,5 %, with 2,2′-methylene-bis- (6(2H-benzotriazol-2-yl)-4-(isooctyl)phenol) isomer fraction not exceeding 1,5 %;

·         Solubility < 5 ng/L in water at 25 °C;

·         Partition coefficient (Log Pow): 12,7 at 25 °C;

·         Uncoated;

·         Median particle size D50 (50 % of the number below this diameter): ≥ 120 nm of mass distribution and/or ≥ 60 nm of number size distribution.

Stakeholders are advised to ensure their cosmetic products comply with the latest EU requirements and should be aware that the change in status for MBBT (nano) came into effect on July 11, 2018.
