The aim of this study was to formulate and evaluate sunscreen products containing an organic UV filter (Tinosorb®S) with an inorganic UV filter (microfined titanium dioxide, TiO2) and in combination with an herbal extract (grape seed) for determining of sun protection factor (SPF) value. The combination of Anisotriazine (Tinosorb®S) and microfined(More)
Ethosome formulations containing phenylethyl resorcinol (PR) were developed. The formulation was produced from 0.5% w/v PR, 0.5% w/v cholesterol from lanolin, 3% w/v L-α-phosphatidylcholine from soybean, 30% v/v absolute ethanol, and water up to 100% v/v. It was characterized by a vesicular size of 389 nm, low polydispersity index of 0.266, zeta potential(More)
The high performance liquid chromatography (HPLC) was used for quantitative determination of phenylethyl resorcinol (PR) which was loaded in the novel vesicle carriers including ethosome, invasome and transfersome formulations, and permeated into pig skin membrane and receptor fluid for skin permeation study. The reverse-phase chromatography was carried out(More)
