ABSTRACT
Virgin Cocunut Oil (VCO) is a pure coconut oil, it has many advantages in health. It has
been circulated in market with unpleasant taste. Therefor, an innovation to find an acceptable
formula by consumer should be carried out. The aimed of this research is to find out the
influence of mix emulsifier toward physical stability of emulsion. Multiple emulsions w/o/w
were made by mix Span 80 with variation concentration 20%, 15%, 10%, and Tween 80. In order
to know the physical stability of emulsion w/o/w should be carried out viscosity test, separation in
room temperature, separation at 40
º
C, separation due to centrifugation, creaming volume,
paticle size, homogenity for 4 weeks storage, and respondent survey with 20 person. The test
result for 3 formulation emulsion for 4 weeks storage showed that formulation are not
homogeneous, but arter the formulas were shaken, it become homogeneous. In various
concentration of Span 80, the longer preperations were storage the higher volume sedimentation
and viscosity. Moreover, the longer preparations were storage, creaming volume and particle size
decrease. Emulsifier combination between Span 80 with variation concentration 20%, 15%, 10%,
and tween 60 in multiple emulsion w/o/w influenced physical stability multiple emulsi w/o/w.
Moreover, this formulation also would be pleasant by consumen.
