Hypochlorous Acid PPM: What to Choose for Every Use

Different Hypochlorous Acid applications require different strengths, measured in parts per million (PPM). Use our guide below to choose the right concentration for your needs.

HOCI 50–100 PPM — Ultra-Gentle Skin & Daily Care

Best for:

• Facial misting and daily skin care
• Sensitive or reactive skin
• Eyelid and lash hygiene
• Baby skin care
• Post-procedure calming (non-open skin)

Why use this strength:
Very gentle for frequent, everyday use.

HOCI 100–200 PPM — Skin, Wound & Personal Hygiene

Best for:

• Acne-prone skin
• Minor cuts and scrapes
• Post-shaving or razor irritation
• First-degree burn aftercare
• Foot and nail hygiene
• Pet skin and minor wound care

Why use this strength:
Stronger antimicrobial action while remaining safe for repeated skin contact.

HOCI 200–300 PPM — Home & Food-Contact Sanitation

Best for:

• Hands and general hygiene
• Kitchen counters and sinks
• Cutting boards and food prep surfaces
• Produce washing
• Makeup brushes and beauty tools
• Pet bowls and toys

Why use this strength:
Food-contact safe with no harmful residue.

HOCl 300–500 PPM — Medium-Heavy Duty Cleaning & Odor-Control

Best for:

• Bathrooms and restrooms
• Gym and fitness equipment
• Shoes and sports gear
• Trash cans and litter areas
• Pet areas, crates, and bedding
• Mold and mildew prevention on hard surfaces
  Break rooms and shared household spaces

Why use this strength:
500 PPM is ideal when you need a stronger cleaning and odor-control option than everyday cleaning, but still want something safe for frequent use around people and pets. It targets odor-causing bacteria and common household microbes without harsh fumes or chemical residue.

HOCl 1,000 PPM — Professional & Heavy-Duty Cleaning

Best for:

• Medical and dental surface cleaning (non-critical equipment
• Daycares, schools, and classrooms
• Commercial kitchens and food service areas
• Veterinary clinics, kennels, and animal shelters
• Warehouses and industrial workspaces
• Large-area misting or fogging applications
• Water-damage and odor remediation projects
  

Why use this strength:
1,000 PPM is the highest-strength option and is designed for high-traffic or higher-risk environments that require rapid, broad cleansing. It offers maximum versatility, as it can be used directly for heavy-duty applications or diluted for lighter tasks, making it popular among commercial, institutional, and professional users.

Not sure which Hypochlorous Acid PPM to choose?

Choose 500 PPM for stronger everyday cleaning and odor control, and 1,000 PPM for commercial-level cleaning, fogging, or situations where you want the most powerful option available. Best for rapid microbial reduction for high-traffic or high-risk environments.

Agriculture, Hydroponics & Post-Harvest Uses

(Typical range: 30–200 PPM, often diluted from higher concentrations)

Best for:

• Irrigation line cleaning
• Root zone pathogen control
• Foliar disease prevention
• Post-harvest produce washing
• Packing and processing sanitation

Why use this strength:
Controls biofilm and microbes without harming plants or leaving chemical residue.

Why Hypochlorous Acid PPM Matters

• Lower PPM = gentler applications for skin and frequent use
• Mid-range PPM = household and food-safe sanitation
• Higher PPM = commercial-grade and heavy-duty sanitation

Higher-strength HOCl (such as 500 or 1,000 PPM) can be used directly or diluted for lighter applications, offering maximum versatility.

Safe, Effective, and Eco-Friendly

• No harsh fumes or strong chemical odors
• No harmful residues
• Safe for use around people and pets when used as directed
• Breaks down naturally into saline (salt water)
