Daftar Isi:
- A study about preparation and characterization of cosmetics emulsion based Virgin Coconut Oil (VCO) has been done. The good emulsion must comply the quality requirement of cosmetic (SNI 16-4399-1996) which includes appearance, pH, viscosity and the Sun Protection Factor (SPF). Preparation of cosmetic emulsion was done with various concentration of VCO 1-25% and cosmetic emulsion without VCO as control. The cosmetic emulsions were characterized included the emulsion stability by using pH test and viscosity test during four weeks of storage, droplet size measurement test, phase separation by centrifugation test and UV absorption to determine SPF values. The result showed that the cosmetic emulsion can provide absorption of UV C region. The increasing of VCO concentration in cosmetic emulsion decreased pH and viscosity of the emulsion but increased droplet size and SPF value. Stability test during storage showed that the pH of emulsion was stable and the viscosity increased with the increasing of the storage time. Centrifugation test showed no phase separation for all emulsions. Cosmetic emulsion with concentration of VCO 7% has the best cosmetic emulsion with homogeneous appearance, pH 6.94 to 6.96 and a viscosity of 295 poise, while the SPF criteria, all emulsion cosmetic emulsions does not fulfilled that the quality requirement of cosmetic in Indonesia.
