Oil Absorption Capacity of Polyethylene Oxide Nanofiber Sheets for Oil Blotting Cosmetic Sheets

Oil blotting cosmetic sheets are important products in the cosmetic and healthcare applications. However, they are limited by their relatively low oil absorption capacity due to their low surface area. In this study, I used an electrospinning method to develop two types of polyethylene oxide (PEO) nanofiber sheets with a large surface area. The properties of sheet, such as the change in the optical transmittance due to oil absorption, the oil absorption capacity, the oil retention capacity, the specific surface area, and thermal and mechanical properties, were evaluated. The oil absorption capacity of PEO nanofiber sheets (25 gauge) was found to be about 11 times greater than that of commercial oil blotting cosmetic sheets and the surface area, as well as the thermal and mechanical properties, increased slightly compared to PEO nanofiber sheets (21 gauge). PEO exhibit ideal characteristics of oil sorbent materials. Therefore, PEO nanofiber sheets with a high surface area are expected to exhibit greater oil absorption capacity than conventional oil blotting cosmetic sheets.
