Preparation of Dried Collagen Mask Sheet Based on Non-woven Mat via Syringeless Electrospinning

The mask sheet containing various effective materials have been widely used for skin improvement over last decades. Recently due to the efforts on reduction of plastic waste, many studies have been conducted to develop driedtype mask sheets. In this study, nanofiber nonwoven was prepared via syringeless electrospinning of collagen (low molecular weight (Mw)) which is effective materials for skin and hyaluronic acid (high Mw) as a supporter. By controlling the composition of the polymer solution and observing the morphology, optimized electrospinning condition have been achieved for mass-production of dry-type mask pack containing large amount of collagen. Through dissolving collagen when water mist is sprayed on the nonwoven, possibility for application to dry-type mask have been also presented.
