Skin of the dorsal areas of ICR mice were pretreated with cream containing 1% BTE(2 mg/cm2 or 20 mg/cm2), then ICR mice were then irradiated with either UVA (236.08 J/cm2), UVB (118.04 J/cm2), or UVC (19.67 J/cm2). After 5 days, the dorsal skin of mice pretreated with cream containing 1% BTE (20 mg/cm2) exhibited normal or slight erythema, slight scabbing and did not show hyperproliferation of keratinocytes compared to control animals. These results demonstrated that 1% BTE had a significant protective effect against irradiation with UVA, UVB, and UVC. BTE as a natural sunscreen agent and the sunscreen effect of the BTE may result from caffeine and gallic acid. The next study objective was to investigate the feasibility of using niosomes as a delivery vesicle for the dermal administration of BTE in vitro as a sunscreen. Multilamellar niosomes were obtained by means of a previously reported 'film' method. In vitro penetration experiments through nude mouse ...
