Development and Evaluation of a Broad spectrum Polyherbal Sunscreen formulation using Solid Lipid Nanoparticles of Safranal.

Introduction: UV absorption properties of bioactive agents has led to their screening and development to provide photoprotection. Safranal is one such secondary plant metabolite obtained from Saffron (Crocus sativus) and reported to possess antioxidant and antisolar properties. The objective of this research was to design a suitable delivery system for the topical delivery of Safranal and to develop broad-spectrum polyherbal sun protection cream with mild photoprotection.
