Solid lipid nanoparticles (SLN/Lipopearls)--a pharmaceutical and cosmetic carrier for the application of vitamin E in dermal products

Solid lipid nanoparticles (SLN, Lipopearls) are nanoparticles made from solid lipids by high pressure homogenization. Incorporation of chemically labile active ingredients into the solid lipid matrix protects against chemical degradation, which is shown for vitamin E. The SLN are physically stable in aqueous dispersions and also after incorporation into a dermal cream as proven by photon correlation spectroscopy and differential scanning calorimetry. Electron microscopy and atomic force microscopy data reveal the spherical shape of the SLN and the detailed structure of the particle surface. Ultrafine particles form an adhesive film leading to an occlusive effect on the skin. The occlusion promotes the penetration of vitamin E into the skin, as shown by the stripping test. In addition to chemical stabilization of active ingredients, occlusive effects on the skin and subsequent enhanced penetration of compounds, the SLN also possess a pigment effect covering undesired colours leading to an increased aesthetic acceptance by the customer.
