Performance & Formulation Insights for Biluna Fine UVS
Ultra-Fine BiOCl for Invisible Skin Perfection
Biluna Fine UVS achieves its uniquely smooth, invisible finish through an ultra-fine 4–8 μm bismuth oxychloride particle size. At this scale, the individual particles are too small to create visible pearl or shimmer, instead producing a soft-focus satin finish that blurs imperfections and evens skin texture. The inherent high refractive index of BiOCl still provides light-scattering benefits and UV screening at this size.
As the finest grade in the Biluna range, Biluna Fine UVS is the preferred choice for formulators seeking the functional benefits of bismuth oxychloride—creamy texture, superior adhesion, UV screening—without any visible pearl or sparkle effect.
Key Technical Advantages in Formulation
The ultra-fine particle size provides exceptional skin feel and blendability, creating a smooth, silky base in powders, creams, and liquids without any grittiness or visible shimmer.
In pressed powders, Biluna Fine UVS delivers excellent binding and cake cohesion at the finest particle level, reducing the need for excessive binders while maintaining a premium creamy texture.
The invisible finish makes it ideal for functional applications such as mattifying powders, soft-focus foundations, and skincare-makeup hybrids where shimmer is unwanted.
