Development of a Green Tea Emulsion Infused Hydrogel

Abstract

The study focused on the development of a hydrogel based herbal eye patch. This study aims to evaluate the benefits of green tea, coconut oil, and the surfactant in creating an emulsion based eye patch. A complete literature analysis was carried out to understand the present research related to nanoemulsions and preparation methods, herbal components, hydrogels, surfactants, and their uses in skincare. The experiment utilizes the water-in-oil emulsion method to prepare the emulsion formulation. The basic materials, green tea, coconut oil, and surfactant were carefully selected based on their antioxidant, anti-inflammatory, and moisturizing qualities for addressing under-eye issues. The emulsions were examined using Malvern Zetasizer (nano-ZS) and optical microscope analysis. The participants' subjective input was also obtained through a questionnaire. Then the prepared emulsion was used to make a hydrogel of carcoxymethyl cellulose (CMC). As future work, improvement of emulsion droplet sizes to nanosizes, comparison of anti-oxidant activities of encapsulated and neat green tea infusions in hydrogel and conducting the user trials after ethical clearance is required.
