The existing plastic microbeads are undecomposed and toxic, and become permanent pollutants, which harm the survival of marine organisms, and after being eaten by organisms such as fishes and shellfishes, the toxic plastic microbeads return to human beings through a food chain, thus threatening the health of human beings.
Therefore, there is a need to design a new bio-based plastic microbead for cosmetics and a preparation method thereof to overcome the above problems.

2) then reacting for 15-20 minutes under 12000-15000psi homogenizing pressure to obtain suspension;
3) and drying the obtained suspension, and screening to obtain the bio-based plastic microspheres.
Further, in the step 3), the obtained suspension is dried by an oven until the moisture content is less than 1%.
