- A study on the ability of VCO as penetration enhancer in comparison to that of dimethylsulfoxide (DMSO) has been undertaken. Four formulas of cream containing 2 penetrants (promethazine HCI and griseofulvin) and 2 cream bases (containing 40% VCO and 10% DMSO) respectively were made. The profil of penetration determined by using Franz diffusion cell (vertical type) with the rnice's skin and pH 6.4 phosphate buffer as membrane and medium respectively. Concenhation of penetrants was determined spectiophotometically at wavelengths 299,2 nm for promethazine HCI and 291,2 nm for griseofulvin. Results indicated that the penetration profile of both drugs didnot follow either zero order, first order or Higuchi kinetic equations; therefore the rate of penefation couldnot determined. Analysis of data according to Korsmeyer-peppas iquation showed the mechanism of penetration process. The ability of VCO as penetration enhancer was thin determined by comparing the Penetration Efficiency (PE) values among formulas. Statistical analysis showed that the ability of VCO as penetration enhancer was far below that of DMSO (p>0,05). Keywords: Virgin Coconut Oil (VCO), dimethylsulfoxide (DMSO), penetration enhancer.
