1. Studies of Sunscreens: Percutaneous Absorption of Benzophenone-3 and Photostability
Abstract : Studies of Sunscreens: Percutaneous Absorption of Benzophenone-3 and Photostability Helena Gonzalez Department of Dermatology and Venereology Institute of Clinical Sciences The Sahlgrenska Academy at Göteborg University Göteborg, Sweden Abstract Aim: To learn more about percutaneous absorption of the photoactive compound benzophenone-3 (BZ-3) and to study the excretion pattern of BZ-3 and its metabolite dihydroxy benzophenone (DHB). We also got the opportunity to develop a reverse-phase HPLC method to analyze BZ-3 and DHB. READ MORE

5. Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability
Abstract : The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. READ MORE
