About Hydrogen Peroxide


Hydrogen Peroxide is an organic, naturally occurring chemical.  It consists of two hydrogen molecules and two oxygen molecules (H 2 O 2 ). 


Hydrogen peroxide has been used for decades for sterilisation of various surfaces including surgical tools and has demonstrated broad-spectrum efficacy against viruses, bacteria, yeasts and bacterial spores.  

Hydrogen peroxide is seen as an environmentally safe alternative to chlorine-based bleaches, as it degrades to form oxygen and water and it is generally recognised as safe as an antimicrobial agent by the U.S. Food and Drug Administration (FDA).


About Sundew Surface Disinfectant
Sundew Surface Disinfectant uses stabilised hydrogen peroxide instead of commonly found quaternary ammonium compounds (quats or QACs).

Why use hydrogen peroxide instead of QACs?


Mode of Action

QAC compounds are a large family of chemicals that all have a quaternary ammonium group in common. They usually have a chemical name ending with ‘…ammonium chloride’ or ‘…onium chloride’, e.g. ‘didecyldimethyl ammonium chloride’ (DDAC) or ‘benzalkonium chloride’ (BAC). The mode of action of QACs is still poorly understood and is often characterised as charged spikes that
can penetrate the cell membranes of microorganisms.


Hydrogen peroxide has been shown to be effective against all forms of microorganisms, including dormant forms with known high resistance (such as bacterial spores and protozoal cysts), and also infectious proteins (such as prions). Hydrogen peroxide is a powerful oxidiser with the basic mechanism of chemical oxidation of cellular components. As a result, hydrogen peroxide provides a broader spectrum of control than other chemical modes of action.


Hydrogen peroxide is highly reactive which advantageously allows it to rapidly eliminate microorganisms with the added unique advantage that it degrades rapidly to benign elements. The components in Sundew Surface Disinfectant will degrade quickly to water, carbon dioxide and oxygen when wiped clean with a damp cloth making it very safe and eco-friendly.

Efficacy
There is conflicting data available around the effectiveness of QACs, the concentration and the contact time needed for control of microorganisms. Some data suggests that QACs can be effective against coronaviruses with a contact time of at least 10 minutes, while other data suggests that QACs aren’t effective against coronaviruses1. Likewise, data exists that suggests QACs may not be as effective in treating robust bacteria such as biofilm formers2. The same studies show that hydrogen peroxide is an effective sanitiser for coronaviruses with a contact time of 30 seconds, and is also effective on robust bacteria. One of the reports recommends hydrogen peroxide as the sanitising solution for medical equipment over QACs.

Independent laboratory tests on surfaces with 29,500,000 per mL Staphylococcus and 23,900,000 per mL E.coli demonstrated that Sundew Surface Disinfectant killed 99.9999% in less than 60 seconds.
