Özet

This study focuses on the preparation, physicopharmaceutical and mechanical characterization of reduced glutathione tripeptide loaded niosome containing emulgels as a novel nanocosmeceutical product. Prepared emulgel formulations were mainly composed of oily phase containing different lipids such as glycerine dibehenate, cetyl alcohol, cetearyl alcohol, etc., and aqueous phase containing Carbopol934 (R) as gelling agent. Niosomal lipidic vesicles prepared from Span 60 and cholesterol were subsequently incorporated into optimum emulgel formulations. The pH, viscosity, and textural/mechanical properties of emulgels were examined before and after the incorporation of niosomes. The viscoelasticity and morphological characterization were performed on the final formulation before the packed formulation's microbiological stability test. The hardness and compressibility results ensured easy removal of the emulgel from the container. Due to the carboxyl groups of Carbopol934 (R), moderate adhesiveness with good cohesiveness was achieved. The rheological characteristics of the emulgels were estimated by oscillatory testing and the data fitted with the Herschel-Bulkley model. Thus, the viscoelastic properties and shear-thinning flow of emulgels were demonstrated. The final formulation was microbiologically stable, and pathogens or skin-irritating allergens were not detected. An anti-aging cosmeceutical preparation containing glutathione tripeptide loaded lipid-based niosome dispersion, suitable for topical use due to its textural and viscosity properties, was successfully produced.
