Cellulose Acetate Microsphere in Cosmetics Application and Sustainability Benefits
AI summary Read the abstract
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.

Effect of Addition of Spheroidal Cellulose Powders on Physicochemical and Functional Properties of Cosmetic Emulsions
AI summary Read the abstract
The cosmetics industry has historically used tiny plastic microbeads as scrubbing and texturizing agents in face creams, but these are now widely banned due to environmental harm. This study evaluated spheroidal cellulose powders — derived from plant material — as a biodegradable replacement, finding that creams containing cellulose particles of two different sizes (2 and 7 µm) performed best, delivering good skin hydration, favorable texture, and high consumer sensory ratings. The results support cellulose-based particles as a viable and genuinely biodegradable substitute for synthetic microplastics in personal care products.
Development of Cellulose Acetate Spherical Microparticles by Means of Melt Extrusion of Incompatible Polymer Blend
AI summary Read the abstract
Researchers developed cellulose acetate (CA) spherical microparticles using melt extrusion of incompatible polymer blends comprising CA with triacetin plasticizer and polyvinyl alcohol (PVA), followed by selective removal of the secondary polymers. Drawing on Wu's equation, particle size was controlled by adjusting shear rate and viscosity ratios, offering a biodegradable alternative to synthetic microplastic particles.
