Safety Class - HCLO Does No Harm

Does your sanitizer harm your skin?

Our Gloves Is Harmless To Humans And Animals.

You may wonder whether your sanitizer is performing efficiently or if it hurts your skin. There is one factor that will affect the efficiency and skin safety of your sanitizer, and it is an important one.

You may have heard about the concept of concentration in sanitizer and disinfectant. But do you know that there is another concept ‘pH level’, which can change the concentration in our daily-use sanitizing products?

  • Different pH level will affect the concentration of free available chlorine in the water. When chlorine dissolves in water, it is available in three forms: chlorine gas (Cl2), hypochlorous acid (HClO) and hypochlorite ion (ClO−). 
  • Hypochlorous acid and hypochlorite ion are disinfection agents. But hypochlorite has low bactericidal efficacy and is unstable because it is ionic. Only the hypochlorous acid form has good antimicrobial activity. Hypochlorous acid is 80-100 times more efficacious than hypochlorite.

Why is pH important?

  • The amount of hypochlorous acid in the solution depends on the pH of the sanitizers. When pH is less than 4, the chlorine will leave as chlorine gas. It will become more and more unstable, toxic and corrosive as the pH decreases. The sanitizer will lose its disinfecting effect immediately.
  • When pH is over 7.5, more than 50% will be hypochlorite (ClO−). As the pH increases, the concentration of hypochlorite will increase. At pH 8, only 20% of the free chlorine molecules are hypochlorous acid. The sanitizer will become more and more inactive as the ClO− form being unstable. It may be concluded that in free residual chlorination, the higher the pH value the less active is the residual because of its lower proportion of hypochlorous acid.

  • Only when the pH is between 4 and 7.5, the free chlorine solution is dominated by hypochlorous acid (HClO). This is why the pH is important. Because hypochlorous acid will be the dominant free chlorine molecule between these pH levels. At pH 5, over 99% of the free chlorine molecules is HClO. At pH 6, over 90% will be HClO.

Measure pH

  • Hypochlorous acid is a weak acid. We can measure the pH with a standard pH test paper. pH test paper has different colors that match each full pH unit from 1 – 14.

  • Hypochlorous acid is the active ingredient of HICC disinfectants. We have performed pH testings at HICC lab on HICC disinfectant products. As the results showed, HICC disinfectant spray has a pH level between 5 - 6.5. At this pH level, the solution consists of most HClO and at the peak level of its activity, which can perform its utmost efficacy of disinfection. 
  • Between pH 5 - 6.5, HICC disinfectant spray can work most effectively because of the purity of the hypochlorous content.

Skin neutral pH

  • Also, it is a pH value range closes to the pH level of human skin and saliva. The pH value of our face and body skin lies between 4.7 – 6 and our saliva has a pH range of 6.2 – 7.6. HICC disinfectant maintains its pH level at 5 - 6.5, which complies with human skin pH degree and performs its disinfecting function at the most actively level.
  • In the same way, the pH value of HICC disinfectant is also in line with the pH value of animal skin, and it can also exert the greatest disinfection effect on animal skin without causing any harm.
  • It has a skin neutral pH and is non-irritant & non-toxic to human skin, even for baby skin. This is why HICCGROOM disinfectant products can be so effective and safe for the skin of pets at the same time. HICCGROOM disinfectant spray can be used for the disinfection of pets disinfecting, baby products, household daily sanitizing, fruits & vegetable cleaning.
