BASF has welcomed the official entry of methylene bis-benzotriazolyl tetramethylbutylphenol (MBBT) as a nano-sized UV filter into Annex VI of the EU Cosmetic Regulation.
MBBT is an ingredient of the BASF product Tinosorb M. Tinosorb M has been on the market (and widely used) since 2000, the year MBBT received its approval as a cosmetic UV active ingredient.
An additional approval, however, was required for products in nano form due to the recast of the EU cosmetic legislation (Regulation (EC) No. 1223/2009) in 2009.
In 2015, the Scientific Committee for Consumer Safety (SCCS) published a positive scientific opinion on the safety of MBBT (nano), which it reconfirmed in January 2018 after assessing additional questions raised by individual EU member states.
It is now BASF's third UV filter in nano form to be approved for use in cosmetics in Europe after Tinosorb A2B in 2014 and Z-Cote in 2016.
