Stability Studies. Accelerated stability studies in the cosmetic area have been performed in periods of 30 to 90
days . For stability studies, samples were weighed (50 g) and packed in glass containers with 100 g of content capacity.
Samples were kept in incubation chambers, each preset at different storage temperature for a period of 30 days and this
testing was called “the accelerated storage period” which is the time between the preparation ofmultiple emulsion and its physicochemical investigation. Glass containers were chosen to accelerate the conditions and hence to accelerate the destabilization of multiple emulsions. Different storage conditions were room temperature (25 ± 1∘C),
