Abstract:
Cocozone Oil(CCO)is one of the ozonated oils,obtained by the ozonation process of Virgin Coconut Oil(VCO),that can be used as a material for skin care products. The purpose of this study was to determine: (1) the optimum time and ozone dose for CCOsynthesis from VCOusing ozonation; (2) the changes in physico-chemical properties of the oil; (3) the change in saturated-unsaturated fatty acids content and the existence any new substances in the CCO. The ozonation of VCOwas carried out for 25 hours, with monitoring at the intervals of 4, 8, 12, 16,20and 25hours, at a constant temperature (25 °C) with an ozone flow of 0.25g/hr. From this study it can be concluded that: (1) The optimal time or dose of ozone required for the synthesis of CCOfrom VCO throughtheozonation process was 25hours or equivalent to 0.0208grO3/ml VCO, (2) Physico-chemical characteristics of the CCOproduced: resulting acid value(AV)was 2.71 mg/gram i.e. an increase of 630%;the peroxide value(PV)obtained was 238,77 mgrek/kg i.e. increase of 3,453%;the Iodine value(IV)was 0 (zero) i.e. a decrease of 100%; and, the viscosity was 13.30 centipoice i.e. it rose 116%; (3) the total content of saturated fatty acid increased by 3.34% whereas the unsaturated fatty acid decreased by98.83; and based on the analysis results of 13C and 1H NMRspectra, the resultant CCOcontains a new substance, thatis aldehydes
