Abstract

Disclosed is increased photoprotection by the combination of Phenylbenzimidazole Sulfonic Acid (PBSA) with Tris Biphenyl Triazine (TBPT). Addition of small amounts of PBSA allows the increase of the photoprotection provided by a filter system including TBPT compared to Ethylhexyl Triazone or Diethylhexyl Butamido Triazone. Enhance of SPF value by 25% is expected.

Increased photoprotection with combination of Phenylbenzimidazol Sulfonic Acid (PBSA) with Tris Biphenyl Triazine (TBPT)

The global trend for the development of sunscreens with greater and greater SPF values leads to the use of higher levels of UV filters. In parallel, there is a wish to reduce the concentration of UV filters in new sunscreen developments due to different reasons (economical-, ecological-, sensorial, or health-related reasons).

Surprisingly, we found that the addition of small amount of PBSA allows the increase of the photoprotection provided by filter system including TBPT compared to ethylhexyl triazine or Diethylhexyl Butamido Triazone. Enhance of SPF value by 25% is expected.

Combination of small concentration TBPT shows increase of sunscreen performance when used together with Titanium dioxide, as well.
