Abstract:
The sunscreening effect can be varied according to the vehicles. Therefore the purpose of this study is to compare the effect of vehicles(bases) on sun protection in p-aminobenzoic acid, cinnamate and benzophenone sunscreens with same concentration (2.5%), We included ointment (white petrolatum), cream (hydrophilic), milky lotion and alcohol as the sunscreen vehicles. The test results can be summarized as follows: We could not recognize a sunscreening effect of sunscreen vehicles which did not contain sunscreening agent. In the case of p-aminobenzoic acid, the mean sun protection factor was higher in the sequence of cream, milky lotion, alcohol, ointment, each showing 9, 95+/-3.67, 8.09+/-2.56, 5.14+/-1.45, 4.35+/-1.46 respectively. In the case of cinnamate, the mean sun protection factor was higher in the sequence of cream, ointment, milky lotion, alcohol, each showing 6 46+/-1.89, 5.42+/-1.49, 4.82+/-1.84, 4.05+/-1.45 respectively. 4. In the case of benzophenone, the mean sun protection factor was higher in the sequence of cream, alcohol, ointment, milky lotion, each showing 5 .26+/-1.56, 4.94+/-1.24, 4.56+/-1.71, 4.18+/-1.23 respectively.
