Abstract

The sun protection should involve substances with protecting activity against both UVB and UVA radiation. In this research the evaluation of thermosensitive microspheres as potential molecules for sunscreen formulations was approached, using modified Boots star rating system. The microspheres, thermosensitive N-isopropylacrylamide derivatives, have potential protecting activity against UV radiation. The MX and DX microspheres, with ethylene glycol dimethacrylate and diethylene glycol dimethacrylate crosslinker respectively, due to theirs thermosensitivity exhibit increase in protecting activity against UV radiation when heated to 45°C. The MX microspheres have higher increase in terms of UV absorbance, comparing to DX microspheres, when heated in the 25°C to 45°C range. Studied microspheres have high potential forapplication as components of sun-screens used in elevated temperatures.
