High Performance Liquid Chromatography (HPLC) was used to determine vitamin D3 content from the
topical dosage form. Self-nanoemulsifying drug delivery systems (SNEDDS) based hydrogel was aimed to optimize the
delivery of vitamin D3 through the skin due to its high lipophilicity. Quantifying vitamin D3 was performed using the
internal standard, vitamin D2, on LiChrocart C18 125-4 reverse phase column. Several characteristics of validation were
referred including specificity, linearity, range, accuracy, precision, limits of detection, and quantification. The mobile
phase was optimized as a mixture of acetonitrile-methanol-water for injection 94:3:3 v/v, and the flow rate was
optimized at 0.8 mL/min at 25°C. Vitamin D3 detection and quantification were observed at a wavelength of 266 nm
using an ultra-violet (UV) detector. The analysis method performed no excipient interference, including separating
vitamin D3 from its matrix. Extraction of vitamin D3 from its matrix was observed using the dialysis membrane, with
agitation (vortex) and no agitation (immersion). The drug content determination was found to be 108.22 % ± 14.77% for
the immersion method and 72.04% ± 33.37% for the vortex method. Further, the high variability of the results indicated
the dialysis membrane was not a suitable method for determining lipophilic drug content from the colloidal polymer
matrix. The other techniques with negligible variation, such as reverse dialysis or subsequent solvent addition, are
preferred.
