50% Hydrogen Peroxide Food Grade H2O2

Whether you're treating irrigation water, sanitizing grow rooms, or supporting aerobic composting, you need a peroxide that performs at the highest level — reliably, safely, and with full regulatory backing. Our 50% Food Grade Hydrogen Peroxide (H₂O₂) delivers maximum oxidizing power in a certified, stabilizer-optimized formula trusted by commercial growers, water treatment professionals, and processing facilities nationwide.

Why 50% Food Grade H₂O₂

Not all hydrogen peroxide is created equal. Our 50% concentration tests at ~50.4% active H₂O₂ — the highest food-grade concentration we carry — and is formulated with an organophosphonate stabilizer package that replaces the transition metal stabilizers found in conventional peroxide solutions. This means a cleaner, more stable product with a longer shelf life and fewer unwanted byproducts.

Certified under ANSI/NSF Standard 60 Drinking Water Additives – Health Effects, this peroxide meets the strictest independent safety and quality standards recognized by health departments, government agencies, and industry associations worldwide. When purity and performance matter, growers and processors choose NSF-certified 50% H₂O₂.

Key Benefits

• NSF® Certified (ANSI/NSF Standard 60) – Independently verified for safety, sanitation, and quality — accepted by health departments and regulatory agencies.
• ~50.4% Active Concentration – Maximum-strength food-grade peroxide for high-demand applications requiring superior oxidizing power.
• Organophosphonate Stabilizer Package – Replaces transition metal stabilizers for a cleaner, more stable solution with fewer impurities.
• Exceptional Shelf Stability – Loses less than 0.5% concentration per year, ensuring long-term potency and value.
• Versatile Sizing – Available from 1 Quart to 55-Gallon drums to match any scale of operation.
• Colorless & Odorless – Easy to handle and integrate into existing workflows without sensory interference.
• Completely Water Soluble – Mixes uniformly into irrigation systems, tanks, and treatment vessels with no residue.

Use Cases

• Hydroponic & Aeroponic Systems – Oxygenates root zones, eliminates anaerobic pathogens, and prevents root rot in recirculating systems.
• Irrigation Water Treatment – Oxidizes biofilm, algae, and organic contaminants in drip lines, reservoirs, and irrigation infrastructure.
• Grow Room & Greenhouse Sanitation – Disinfects surfaces, trays, tools, and equipment between cycles to reduce pathogen pressure.
• Drinking Water Treatment – NSF 60-certified for use as a drinking water additive at approved dosage levels.
• Aerobic Composting – Accelerates decomposition and suppresses anaerobic bacteria in compost piles and windrows.
• Food Processing & Sanitation – Used in food-contact surface sanitation and processing environments where food-grade certification is required.

Directions for Use

• Always wear appropriate PPE: chemical-resistant gloves, eye protection, and protective clothing before handling.
• Dilute to the required concentration using clean water before application — never apply at full strength to plants or food-contact surfaces.
• For hydroponic reservoir treatment, typical dosage is 1–3 mL of 3% equivalent per gallon — dilute accordingly from 50% stock.
• For irrigation line flushing, dilute to 3–5% and circulate through lines; flush with clean water afterward.
• For surface sanitation, dilute to 3% and apply via spray or wipe; allow contact time before rinsing.
• Dosage levels for drinking water applications shall be in strict accordance with NSF Standard 60 requirements.
• Store in original container in a cool, dry, well-ventilated area away from combustibles and incompatible materials.

What Growers Are Saying

"The 50% concentration gives us the flexibility to dial in exact dosing for our reservoir system. Root health has been noticeably better since switching."

— Marcus T., Commercial Hydroponic Grower

"NSF certification was a non-negotiable for our facility. This product checks every box — clean formula, consistent concentration, and reliable supply."

— Sarah P., Greenhouse Operations Manager

"We use it for both irrigation treatment and end-of-cycle sanitation. One product, multiple applications — and the shelf life is excellent."

— Daniel R., Indoor Cultivation Facility

Frequently Asked Questions

What makes this 50% H₂O₂ different from standard hydrogen peroxide?
This is a food-grade, NSF-certified formulation with an organophosphonate stabilizer package — not the transition metal stabilizers found in most commercial peroxide. It's cleaner, more stable, and independently verified for safety and quality.

Is this safe to use in hydroponic systems?
Yes. When properly diluted, food-grade H₂O₂ is widely used in hydroponic and aeroponic systems to oxygenate root zones and eliminate anaerobic pathogens. Always dilute to the appropriate working concentration before use.

How do I dilute 50% H₂O₂ to a lower concentration?
Use the formula: C1V1 = C2V2. For example, to make 1 gallon of 3% H₂O₂ from 50% stock: (3/50) × 3785 mL = ~227 mL of 50% H₂O₂ topped up to 1 gallon with water. Always add peroxide to water, not water to peroxide.

How long does 50% H₂O₂ stay potent?
Hydrogen peroxide at 50% concentration loses less than 0.5% of its initial concentration per year under proper storage conditions. Store in a cool, dry, well-ventilated area away from heat, light, and combustibles.

Is this product compatible with organic growing programs?
Hydrogen peroxide is not OMRI-listed for certified organic use. However, it is widely used in conventional and transitional growing programs. Check with your certifier before use in certified organic operations.

What sizes are available and which is right for me?
We offer 1 Quart, 4x Quarts (1 gallon, no hazmat fee), 15 Gallon, and 55 Gallon drum. Home growers and small operations typically start with quarts; commercial facilities and processing operations favor 15G or 55G drums for cost efficiency.
