- Abstract
The synergistic effect and mechanism of two chemical sunscreens, BEMT and MBBT? have been studied. UV absorption spectrum study suggests that the UV absorption peaks of BEMT and MBBT shift when the polarities of solvents varied. In ethanol (a typical semi-polar solvent), the UV absorption capacity of BEMT is reduced compared to its capacity in a non-polar solvent of isooctane. While the addition of MBBT can offset the impact of solvent polarity. In terms of the emulsions with BEMT as the only sunscreen agent, in vitro test indicates that SPF is increased with the solvent polarity, and the addition of MBBT can offset this impact. Sunscreen efficiency can be significantly enhanced via combining water-phase and oil-phase sunscreen agents.
