Abstract
The present invention is a hydrated, nanocellulose nonwoven sheet and method for manufacturing the nanocellulose sheet having dermatologically active ingredients. The sheet is formed through a high pressure or vacuum filtration process from a dilute suspension. This suspension, which contains the nanocellulose, may also contain dermatologically active ingredients. The dermatologically active ingredients are incorporated into the unwoven sheet. The dilute suspension may contain binding agents that improve the strength of the nonwoven nanocellulose sheet. These binding agents can also be cross-linked after the formation of the sheet by applying other chemical agents or treating the sheet after formation.
