Sustainable Spheres
75 µm – 450 µm
Sustainable MCC Spheres are fully microcrystalline cellulose-based and available in various particle sizes to meet specific formulation needs.
This innovative product from European Union is engineered for different applications, ensuring optimal performance thanks to its high sphericity. This flagship product is made of 100% cellulose, featuring low nitrite levels, a reduced carbon footprint and full compostability.
Particularly in cosmetics, it can replace microplastics, providing a pure and sustainable alternative from nature.
