Development and evaluation of a cream containing solid lipid nanoparticles loaded with Vitamin E

Solid lipid nanoparticles (SLNs) have several potential applications in the topical drug delivery. The current project aimed to prepare and characterize SLNs loaded with vitamin E for topical administration and incorporating the prepared SLNs in a cream base. Further, the permeation of prepared SLNs was studied through a synthetic membrane and the release profiles were compared with vitamin E cream. The prepared SLNs were subjected to stability studies at two different temperatures. Hot homogenization followed by dilution technique was used for the preparation of SLNs. In this project, PDMS membrane was used to mimic the skin for permeation studies. From the results of this study, it can be concluded that prepared SLNs had enhanced the permeation of vitamin E as compared to vitamin E cream.
