PHA microsphere for medical cosmetology

3 hydroxybutyric acid (3HB), a degradation product of 1 PHA, is more mildly acidic The dissociation constant of 3HB, the main degradation product of HA, is pKa = 4.70 The main degradation product of PLA, LA (lactic acid), is more acidic, and the dissociation constant pKa = 3.08 PHA degraded more slowly and PLA degraded more quickly More LA (lactic acid) is released from PLA per unit time From the perspective of biocompatibility, PHA is an excellent choice for open porous microspheres (OPM) in this study Ningbo Neon Lion Technology Co., Ltd. has been focusing on the production and research and development of bio-based materials for more than 10 years. Through more than 10 years of efforts, it has formed a complete industrial chain of bio-based degradable plastics and bio-based plastic additives. At present, the company produces PBS, PBAT, PLA, PVA, PBSA, PBST, PHA, PPC, PCL, and a series of epoxy vegetable oils. The comp…
