Leveraging advanced thermo-mechanical properties, Wacker HDK N20 PHARMA is a pharmaceutical-grade hydrophilic fumed silica with 175-225 m²/g surface area and ≥99.8% SiO₂ purity. Its nano-structured particles (7-40nm) enhance powder flowability and liquid thickening, compliant with EP/USP/NF pharmacopeias (produced under ISO 9001, ISO 14001, FSSC 22000, and IPEC standards) for tablet, capsule, and liquid formulations
Pharma-Safe: EP/USP/NF certified, ultra-low heavy metals (As<3ppm, Pb<25ppm), GMP-compliant
Flow Control: 0.1-1% dosage reduces angle of repose by 30%, eliminating hopper bridging
Thixotropic Efficiency: Thixotropic index 2.0-2.5 in liquids with 0.5-5% adjustable viscosity
Fast Disintegration: Cuts tablet disintegration time by 40% as a disintegrant
Process Stability: <5% batch variation, 24-month shelf life at 50℃
Tableting: Improves powder flow (e.g., acetaminophen blend angle of repose from 55° to 35°), reducing capping
Capsule Filling: Prevents API segregation, +25% filling uniformity
Liquid Formulations: Thickens syrups/suspensions, extends stability to 36 months
Wet Granulation: +15% yield as anti-adherent in granulation
Topicals: Enhances thixotropy in creams/gels, +20% spreadability
