Cellulose Acetate Microsphere in Cosmetics Application and Sustainability Benefits
Summary
Researchers developed biodegradable cellulose acetate microspheres as a sustainable replacement for synthetic microplastic particles in cosmetics, producing smooth spherical particles via thermal phase separation that deliver comparable sensory performance while avoiding persistent plastic pollution in the environment.
In recent years, microplastics have become a global issue. Our research group is working on the development of spherical particles using cellulose acetate, which is safe and environmentally friendly, through a polymer thermal phase separation. The cellulose acetate particles produced by our group exhibit high surface smoothness, which results in a smooth texture when used as a cosmetic sensory modifier.
