| Summary: | Application of water-in-oil emulsion in the formulation of color cosmetic is very common. However using natural water-soluble pigments as cosmetic colorant is not general in the cosmetic industry although we knew the side effect from using synthetic colorant. This study concerns one of the most important problems in using natural pigment which was to obtain the lip moisturizer formulation and to determine emulsion stability. Roselle is a local potential pigment source which is added into castor oil as the oil phase with the aid of Span 80 and Tween 85 as emulsifier. Several emulsions were prepared using different proportions of emulsifiers and the most suitable hydrophilic lipophilic balance (HLB) value for color emulsions was determined to continue with the finding of stable formulation. In addition, stable formulation was determined and emulsions stability were studied during the observation period. Emulsions were analyzed by using viscosity measurement, in order to determine a suitable formulation of emulsion. The formulation of emulsion was stabilized under HLB value of 5.3 which is 75% of Span 80 and 25 % of Tween 85 |
