Physical and Chemical Properties: Neutral pH stability: pH 6.8-7.8 (matches human physiological environment), avoiding tissue irritation from traditional high alkaline glass (pH > 8). Nanoporous structure: Porosity 40%-70%, pore size 10-500nm (adjustable), specific surface area 50-300 m²/g, providing cell adhesion and nutrient transmission channels. Ion-controlled release: Ca²⁺ (5-20mM), Si⁴⁺ (1-5mM), Na⁺ (10-30mM) etc. (release rate controlled by ingredient design). Biodegradability: Degradation cycle 3-24 months (synchronized with bone regeneration/ tissue repair), degradation products participate in body metabolism (e.g., silicate →Sugar from grapesAmine Synthesis).

2. Biological Characteristics - Bioactivity: Rapidly forms hydroxyapatite (HA) layer on the surface (bionically mineralized, activated in 12-24 hours), promoting cell adhesion (osteoblasts/fibroblasts). Neutral environment inhibits inflammatory factors (e.g., TNF-α, IL-6), protecting macrophage activity (phagocytic efficiency increased by 20%-30%). Synergistic Effectiveness: Complexed with hyaluronic acid (HA) (hydrogen bond action) to enhance moisturizing power (water retention extended by 4 hours), and with plant extracts (Centella asiatica extract) (inhibits COX-2 by 75%). Tissue Compatibility: pH neutral value is stable, matches physiological environment, avoids irritation, maintains structural stability in aqueous phase (pH 5.5-7.0), and in oil phase (petrolatum, silicone oil), with better compatibility than traditional active ingredients (e.g., vitamin C, retinol).
