Document Type and Number:
WIPO Patent Application WO/2023/188980
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a hydrogel in which a large amount of volatile components can be stably dispersed and which has superior ability in releasing volatile components in a sustained manner.　Provided is a hydrogel containing porous resin particles and volatile components. The porous resin particles have a pore diameter of 5-30 nm and an oil absorption of 50-700 ml/100 g. The mass ratio of the volatile components (A) to the porous resin particles (B) contained in the hydrogel is (A):(B)=1:1 to 1:4.
