Submission II on MBBT was submitted to the Scientific Committee on Consumer Safety (SCCS) in January 2013 to assess the safety of its nano form. The SCCS opinion concluded that:
“Since no appropriate data on genotoxicity of nano form of MBBT were provided, no conclusion on the safety of this substance can be drawn. However regarding systemic effects there seems no concern for the dermal application of nano-sized MBBT.” (SCCS/1443/11)
In August 2014 BASF has transmitted a new safety dossier that summarizes analytical and toxicological results obtained for genotoxicity studies performed with nano and non-nano forms of MBBT.

Opinion

1. In light of the new data provided, does the SCCS consider Methylene bis-benzotriazolyl tetramethylbutylphenol (CAS No.103597-45-1) safe when used in cosmetic products in its nano forms under the current use conditions up to a maximum of 10%?

The calculation for margin of safety in this Opinion is based on a 39-week dermal toxicity study in the mini-pig, as no repeated dose toxicity study with the nano-sized material is available in rats. Also, dermal penetration data are not …
