HOLLOW SPHERICAL PARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/195476
Kind Code:
A1
Abstract:
Provided is a hollow spherical particle that can be prepared with superior safety and greater ease. A hollow spherical particle according to the present invention is a self-organizing body of lignin, wherein the content of the lignin in a β-O-4 ether structure is 50% or greater, and the solubility with respect to 60 to 80% ethanol at 25°C is 2 w/v% or greater.
