Formulation & Performance of GlassMira VBG87A
The Borosilicate Advantage for Unmatched Sparkle
GlassMira VBG87A is engineered on a Calcium Aluminum Borosilicate substrate—precision glass flakes that are exceptionally smooth and highly transparent. This allows for superior light reflection and color purity compared to natural mica. With a tightly controlled 40–150 μm particle size, VBG87A produces a brilliant, glittering appearance with dramatic multi-chrome travel from violet to blue to green.
Optical layering of Titanium Dioxide and Tin Oxide on the borosilicate platelets tunes interference and reflection, yielding a vibrant, angle-dependent color shift with a high-end, sparkling finish.
Mastering Large Particle Formulations
The large particle size is essential for sparkle intensity but requires specific formulation strategies. In liquid and gel systems, use robust, shear-thinning rheology (e.g., hectorite/synthetic clays, organoclays, or appropriate gellants) to form a stable, gel-like network at rest that prevents settling while allowing smooth application.
For pressed powders, employ a strong binder system to optimize adhesion and minimize fallout while preserving the reflective, faceted look. In loose formats, proper surface treatment or base selection can enhance payoff and comfort despite the larger particle size.
Key Formulation Benefits
- Dramatic Color Travel: Striking violet–blue–green shift for premium, multi-chrome effects across eyes, lips, face, and nails.
- Superior Sparkle & Brilliance: Borosilicate glass delivers exceptional clarity and reflectivity for a brighter, more eye-catching finish than mica-based pearls.
- Clean & Conscious: Vegan, cruelty-free, and classified as natural under ISO16128 to meet modern clean beauty expectations.
- Versatile Application: Performs in pressed and loose powders, gels, liquid eyeliners, lip gloss, and nail systems with proper suspension or binding.
