Ascorbic acid is also called Ascorbates or Vitamin C. The present study was investigated to carried out for the preparation of multiple emulsion for the care of skin (cosmetics); multiple emulsion water-in-oil-in-water (w/o/w) formulations containing Ascorbic acid was prepared by Primery Emulsion (50.0ml) (Composition: Ascorbic acid- 100mg, Caster oil- 40.0ml, Span20- 2.5%w/v, Water- 10.0ml), Water (50.0ml) and Tween80- 2%w/v. Multiple emulsions were characterized with different parameters like pH (by pH meter), Average particle diameter (by Occular microscopy), Density and viscosity of the multiple emulsion (by viscometer), and in-vitro drug release study (U.V. Spectroscopy).
