Benefits of technology
The nanocellulose composite sheet demonstrates enhanced skin adhesion, high porosity, and efficient delivery of dermatological agents, overcoming the limitations of traditional hydrogel formulations.
Problems solved by technology
However, micronized cellulose in the porous absorbent structure is a dry composition, which makes it difficult to deliver other ingredients to the skin.
Nonetheless, this does not apply to plasters or medical dressings with nanocellulose.
Unfortunately, such masks using established hydrogel formulations tend to have poor contour conformability, inadequate skin adhesion, and limited transfer efficiency of active ingredients to the skin.

Abstract
A method of manufacturing a two-layer nanocellulose composite sheet is provided. The two-layer nanocellulose composite sheet is comprised of a moisturized nanocellulose material and a fabric. The method includes the steps of dispersing a diluted nanocellulose suspension onto a fabric, and partially drying the diluted nanocellulose suspension until the diluted nanocellulose suspension is transformed to the moisturized nanocellulose material bonded to the fabric. Thereby, a surface of the moisturized nanocellulose material is bonded by mechanical adhesion to a surface of the fabric. The nanocellulose composite sheet manufactured by this method has contour conformability, excellent skin-adhesion, and high capacity for moisture retention and release, and is ideal for dermatological treatments. An apparatus for manufacturing the nanocellulose composite sheet is also provided.
