Abstract

To shield their skin from the harmful effects of UV radiation, many people regularly use topical sunscreen lotions [1]. Recent research have, however, highlighted the dangers of UV filter percutaneous absorption, which can result in unfavourable systemic side effects such hormone imbalances and allergies [2]. This study created a novel sunscreen formulation using starch microsponges as the primary carrier for the organic sunscreen benzophenone [3]. Nitrogen adsorption/desorption analysis and scanning electron microscopy were used to analyse the generated starch microsponges [4]. The findings demonstrated that starch microsponges had high BET surface areas, spherical porous morphologies, and pores smaller than 200 nm [5]. Scanning electron microscopy, differential scanning calorimetry, and benzophenone-3-loaded starch microsponges were used to load benzophenone-3 into the starch microsponges. Nitrogen adsorption-desorption experiments, scanning calorimetry, powder X-ray diffraction, and Fourier transform infrared spectroscopy [6]. The findings supported the effective entrapment of benzophenone-3 within the nanopores of starch microsponges [7].
