Interfacial
Entropic
Natural, biobased, and biodegradable sustainable sensory powder for cosmetics and personal care that is used both as a biodegradable replacement for synthetic polymeric microspheres (microplastics) such as Nylon-12 and PMMA and as a cost-conscious replacement for biodegradable solutions such as cellulose microspheres.

Skincare & Personal Care FormulationFunction Description:
Biodegradable polymeric microspheres that provide sensory modification and aesthetic effects in personal care formulations — delivering soft-focus, mattifying, texturizing, and a smooth/ball-bearing feel. They act as a particulate extender/filler and influence feel, opacity, and stability in both anhydrous and emulsion systems.Applications & Uses:
- Designed for color cosmetics (loose powder, pressed powder, liquid foundation, lip & cheek sticks, mascaras), skincare and suncare (serums, creams, lotions, SPF lotions/oils), and hair care (dry shampoo, styling aids). Suitable for hot-pour, emulsion, anhydrous systems and powder applications
- used to impart soft-focus, mattifying, texture, opacity, and stabilizing effects in formulations.
Benefits:
- Biobased and biodegradable alternative to synthetic microplastics
- non-nano spherical shape for predictable optical and tactile effects
- median particle size 5–10 μm optimized for soft-focus and mattifying performance
- compressible for pressed powders (works at 400–600 psi)
- compatible with common cosmetic oils and humectants
- Index of Natural Origin (INO) = 1
- helps formulators replace Nylon-12/PMMA or cellulose microspheres.
Performance Attributes:
- Spherical microspheres with a median particle size of 5–10 μm and relative density ~1.27 g/cm³ provide consistent soft-focus and mattifying performance
- melting point ~150°C provides thermal stability during processing
- highly compressible for pressed powders (compatible with standard and higher compression pressures)
- compatible with a wide range of lipophilic and hydrophilic carriers, enabling formulation versatility and reduced usage levels versus some synthetic microspheres.
