SYNERGISTIC UVR ABSORBING ADJUVANT COMBINATION
A composition comprising ethylhexyl methoxycrylene, a compound with multiple phenyl groups, and a carrier oil is provided. The composition may also include an organic sunscreen. The combination exhibits an unexpected synergistic effect, in that the photoactive properties of the composition (e.g., SPF, UV absorption) are significantly higher than would be predicted based on the values for each of the components individually.

12 . A composition, comprising:
0.25 wt % to 2.0 wt % of ethylhexyl methoxycrylene, a derivative thereof, or a combination of the two;
0.2 wt % to 1.0 wt % of a compound having multiple phenyl groups selected from the group consisting of benzene sulfonic acids, salts of benzene sulfonic acids, styrene/ethylene/butadiene block copolymer, and combinations thereof; and
a carrier oil selected from the group consisting of mineral oil, isopropyl myristate, butyloctyl salicyclate, ethylhexyl salicyclate, and any combinations thereof.
13 . The composition of claim 12 , wherein said compound having multiple phenyl groups is a styrene/ethylene/butadiene block copolymer.
