Preparation And Characterization Of Grapeseed Oil-Based Emulsion Containing Vitamin C

Abstract

Grapeseed oil is known for its antioxidant and anti-inflammatory properties which serves as an excellent ingredient for anti-acne and anti-aging products in cosmetic industry. In addition to that, Vitamin C is also one of the most common active ingredients in cosmetics. However, it is impossible to use vitamin C in its stable free form without a carrier such as emulsion system. Emulsion is a mixture of two or more immiscible liquids, for instance water and oil. Therefore, grapeseed oil can be used as the oil phase of the emulsions although they are thermodynamically unstable, hence surfactants are needed to stabilize the system. Therefore, this study was proposed to prepare and characterize a stable grapeseed oil-based emulsion as carrier for vitamin C.
