Inspired by the ASTM D4265-98 method for staining, the emulsion uses 5% Artificial Sebum in Eccrine Perspiration. Oleic acid is added as an emulsifier. Prepared without dust/dirt for a more universal application, this emulsion mimics non-exercise induced skin surface film (SSFL). As SSFL, it can be used to test any topical use product or the stability of any article that will come in contact with human sweat. This product requires refrigeration to remain in solution and prevent rancidity.
