Document Type and Number:
WIPO Patent Application WO/2018/186278
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide polyhydroxyalkanoate (PHA) particles and an aqueous dispersion of the same, in which: the PHA particles exhibit excellent dispersibility in an aqueous dispersion and have excellent film formation capability; and a compact obtained from the PHA particles or the aqueous dispersion of the same has a good tone and a suppressed offensive odor. Provided are polyhydroxyalkanoate particles that include: polyhydroxyalkanoate in the form of particles; and peptidoglycan covering a part of or the entire surface of the polyhydroxyalkanoate. The content of the polyhydroxyalkanoate is 98.0 wt% or greater and the content of the peptidoglycan is 0.1 to 1.0 wt%.
