The purpose of this research was to study the stability of an emulsion containing UVA, UVB and infrared sunscreens after storage in different types of packaging materials - glass and plastic flasks; plastic and metallic tubes. The samples, emulsions containing benzophenone-3 (B-3), octyl methoxycinnamate (OM and Phycocorail, were stored at 10, 25, 35 and 45 deg C and representative samples were analysed after 2, 7, 30, 60 and 90 days period. The stability studies were conducted by analysing samples at pre-determined intervals by high performance liquid chromatography, along with periodic rheological measurements.
