Title:
TISSUE CONTAINING SODIUM HYALURONATE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/040031
Kind Code:
A8
Abstract:
Disclosed are a tissue containing sodium hyaluronate and a preparation method therefor. The average fiber length of the tissue is 0.7-1.4 mm; the water content in the tissue is 8-20 wt%; the water activity A of the tissue satisfies the following formula: A<-13.78*M2+4.89*M+0.3, wherein M is the water content in the tissue. The tissue contains sodium hyaluronate and a water activity modulator; by adjusting the relationship between the water activity and moisture in the tissue, the friction force of the high-water-content tissue on which sodium hyaluronate is coated can be significantly reduced.
