What is the difference between Hypochlorous acid (HOCl) and sodium hypochlorite (NaOCl) for the Echo Clean

The Echo Clean and the Echo Ultimate can both produce Hypochlorous acid (HOCl). 

Only the Echo Clean can also produce sodium hypochlorite (NaOCl) because it requires the addition of Kosher Salt prior to the electrolysis process.

Hypochlorous acid (HOCl) and sodium hypochlorite (NaOCl) are both chlorine-based disinfectants with different chemical properties and applications. Here is a comparison of the two:

Hypochlorous Acid (HOCl):

  1. HOCl is a weak acid that forms when chlorine dissolves in water.
  2. It is a powerful oxidant and highly effective disinfectant, killing bacteria, viruses, fungi, and algae.
  3. HOCl is considered to be a more potent germicide than NaOCl due to its ability to penetrate cell walls more efficiently.
  4. It has a neutral pH, which makes it less corrosive and safer for use on various surfaces, including sensitive materials.
  5. HOCl is commonly used in wound care, eye care, and dental care products due to its lower cytotoxicity compared to NaOCl.
  6. It has a short shelf life and can lose its effectiveness over time when exposed to light, heat, or air.

Uses of Acid Water (Hypochlorous Acid):

  1. Treats acne, eczema, and other skin issues.
  2. Powerful disinfectant for surfaces.
  3. Wound care. 
  4. Eye care (HOCI can only be used for eye care in very small, diluted doses. Do not use HOCI on your eyes before consulting your primary healthcare professional.)
  5. Used in organic crop production. 
  6. Produces preservatives. 
  7. Used for diabetic skin ulcers.
  8. Food disinfectant.

Sodium Hypochlorite (NaOCl):

  1. NaOCl is an alkaline compound that forms when chlorine reacts with sodium hydroxide (NaOH).
  2. It is a widely used disinfectant, popularly known as household bleach, and is effective against a broad range of microorganisms.
  3. NaOCl is less effective as a germicide compared to HOCl, but it is still a potent disinfectant when used at higher concentrations.
  4. It has a higher pH, which makes it more corrosive and potentially harmful to certain surfaces and materials.
  5. NaOCl is not typically used in medical applications due to its higher cytotoxicity compared to HOCl.
  6. It has a longer shelf life and is more stable compared to HOCl, making it a popular choice for large-scale disinfection and water treatment.

Uses of Sodium Hypochlorite (acid water with dissolved salt):

  1. Bleaching agent.
  2. Strong disinfectant.
  3. Used in healthcare facilities for cleaning and disinfecting.
  4. Antiseptic, used to clean topical wounds.
  5. Anti-infective. 
  6. Can remove mold stains and dental stains.

Both hypochlorous acid and sodium hypochlorite are effective disinfectants, but their specific properties and applications can vary. Choosing the appropriate disinfectant depends on factors such as the desired germicidal strength, material compatibility, shelf life, and safety considerations.
