Title:
DOUBLE CROSS-LINKED COPOLYMER, PREPARATION METHOD THEREFOR AND PATCH COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/038937
Kind Code:
A1
Abstract:
The present invention relates to a double cross-linked copolymer, a preparation method therefor and a patch comprising same. The double cross-linked copolymer has the ability to inhibit the activity of 5α-reductase and the effect of promoting hair growth, thereby enabling the use thereof in hair loss prevention and hair growth promotion, and also has reduced biodegradability compared to conventional hyaluronic acid, thereby allowing desired effects to be exhibited for a long time. In addition, by using the double cross-linked copolymer, a hair loss prevention product can be provided in the form of a patch with microneedles, which can be easily applied to and removed from the scalp, instead of oral medicines or hair loss prevention products that have been administered through injection.
