Title:
COSMETIC SHEET MASK HAVING EXCELLENT HEAVY METAL ADSORPTION PERFORMANCE, AND METHOD FOR MANUFACTURING SAME BY USING ELECTROSPINNING
Document Type and Number:
WIPO Patent Application WO/2021/221214
Kind Code:
A1
Abstract:
The present invention relates to a sheet mask having a heavy metal adsorption effect and having excellent stability and support capacity, and a manufacturing method therefor, the sheet mask being obtained by electrospinning a spinning composition comprising: a silica composite having thiol groups (-SH) introduced onto the surface of silica; and a polymer comprising a polyvinyl alcohol and a polyacrylic acid.
