Product Description Sodium Percarbonate (often referred to as "solid hydrogen peroxide"):1. Chemical IdentityChemical Name: Sodium PercarbonateSynonyms: Sodium carbonate peroxyhydrate, Sodium carbonate hydrogen peroxide, PCS, Solid Hydrogen PeroxideEC Number: 239-707-6Molecular Formula: 2Na2CO3 · 3H2O2 (Common representation) / Na2CO3 · 1.5H2O2 (Shows H2O2 ratio)Molecular Weight: 315.98 g/mol (for 2Na2CO3 · 3H2O2)Active Oxygen Content (Theoretical): 15.28% (equivalent to ~32.5% H2O2)Typical Assay (Technical Grade): 12.5% - 14.5% Active Oxygen (~85-95% of theoretical)2. Physical PropertiesAppearance: White, crystalline, free-flowing powder or granules.Odor: Faint characteristic odor (ozone-like during decomposition).Bulk Density: 0.8 - 1.2 g/cm3 (depends on granule size and compaction).Solubility: Highly soluble in water.Solubility (~20°C): ~150 g/L.Solution Properties: Forms solutions of sodium carbonate (Na2CO3) and hydrogen peroxide (H2O2).pH (1% Solution): ~10.5 - 11.0 (alkaline).Melting/Decomposition: Decomposes before melting.Stability:Solid: Moderately stable when stored cool, dry (<30% RH), and protected from moisture, heat, and contamination. Sensitive to humidity (caking, decomposition).Solution: Decomposes rapidly in solution, especially upon heating, exposure to light, transition metals (Fe, Cu, Mn), or alkaline conditions. Stabilizers are often added.Thermal Decomposition: Starts significantly around 50-60°C (122-140°F), releasing oxygen and water vapor. Rapid decomposition/oxygen release typically occurs >100°C (>212°F). Decomposes to sodium carbonate, water, and oxygen.Active Oxygen Stability: Losses occur over time depending on storage conditions (heat, moisture).3. Chemical PropertiesPrimary Function: Strong oxidizing agent (source of active oxygen).Mechanism: Releases hydrogen peroxide (H2O2) upon dissolution in water. H2O2 then acts as the bleach/oxidizer.Bleaching Action: Effective at temperatures as low as 40°C (104°F), optimal around 60-80°C (140-176°F). Works best in alkaline conditions (pH 10-11).Reactivity: Reacts vigorously with strong reducing agents. Incompatible with acids, transition metals, organic materials, ammonium salts (risk of ammonia gas release), chlorine compounds, and certain catalysts.4. Applications (Primary Uses)Laundry Detergents & Boosters: Primary bleaching agent in "color-safe" or "non-chlorine" bleach powders/liquids/gel tabs.Household Cleaners: All-purpose cleaners, bathroom cleaners, mold/mildew removers, carpet cleaners, dishwasher detergents.Industrial & Institutional (I&I) Cleaning: Laundry operations, food & beverage processing equipment cleaners, CIP systems.Organic Synthesis: Oxidizing agent in various chemical reactions.Pulp & Paper: Bleaching agent.Environmental Remediation: Soil remediation, wastewater treatment (oxidizing contaminants).Potable Water Treatment: Disinfection.5. Performance DataBleaching Efficiency: Highly effective on organic stains (coffee, tea, wine, fruit, grass, blood). Less effective on dye stains compared to chlorine bleach.Disinfection: Effective against a broad spectrum of bacteria, viruses, and fungi at appropriate concentrations and contact times (driven by released H2O2).6. PackagingTechnical grade typically supplied in:Multi-wall paper sacks with inner polyethylene liner (25kg, 50kg).Polyethylene-lined fiber drums (200kg).Bulk bags (1000kg).Key AdvantagesConvenient solid form of hydrogen peroxide.Environmentally benign decomposition products (Na2CO3, H2O, O2).Effective bleach at lower temperatures than sodium perborate.Color-safe for fabrics.Biodegradable.
