how does zoono work?

Check out the list of frequently asked questions below! If you don’t find the answer to your question, please feel free to get in touch.


Zoono works by the formation of a mono-molecular layer of covalently bound biocidal molecules based around silicone polymer chemistry. When applied to a surface by spraying, wiping or ‘fogging’, Zoono leaves behind a mono-molecular layer that permanently bonds to the surface. Our water-based sanitisers add a long lasting antibacterial protective layer to hands and surfaces. Once dry, Zoono becomes active.  It resembles a layer of microscopic pins that attract, pierce and kill pathogens and germs – the same principle as a pin popping a balloon. These molecules are antimicrobial, silane-based polymers that covalently bond to the surface forming a barrier of positively charged microscopic pins. The positively charged microscopic pins attract and pierce negatively charged pathogens. The pins rupture the cell walls. This causes the pathogen to break up with lethal effect. It is designed to help support routine hand washing and surface cleaning to provide enhanced protection in between

Our products are made from 99% deionised water, 1% active ingredient – Quaternary Ammonium Compound. QAC is derived from a molecule of sand which goes through a synthetic process to activate it. Our products do not contain alcohol, phenoxyethanol, triclosan or fragrance. 

Zoono can be used on all surfaces in the home. Follow the instructions on the label – use Zoono after your regular cleaning routine on clean, dry surfaces and allow approx. 10 minutes for drying. For commercial / technical applications, industry specific written protocols are recommended and are provided as required. Zoono is designed to be used alongside regular cleaning habits to provide enhanced protection in between.

Simply apply the Zoono GermFree24 Hand Sanitizer 50ml foam pump with two squirts liberally to washed, clean, dry hands and gently rub hands until dry.

On application, the hands feel silky and moisturised without leaving a visible film or coating. A single application of Zoono Hand Sanitiser will act like a glove, providing an invisible bond to the skin for 24 hours without the need for reapplication.

No. GermFree24 Hand Sanitiser does not wash or rub or evaporate off and will remain active on the skin for 24 hours. Normal washing of the hands and drying with a towel, will not affect efficacy.

No. Once GermFree24 has bonded to the skin, it remains effective until such time the skin naturally exfoliates. An application of alcohol in the meantime, will not affect GermFree24 efficacy.

Yes. Zoono Hand Sanitiser has been dermatologically tested in Germany on a range of skin types (older people, young people, fair skinned and dark skinned people etc) – with zero reactions recorded. 

No. It forms an antimicrobial barrier on the skin and will not stain clothing nor discolour skin.

You don’t have to… Hand Sanitiser remains active on the skin until natural exfoliation occurs and this usually takes 72 hours or so (it varies due to factors like exercise, work environment etc). But within high risk environments (Health Care etc), some professionals prefer to use GermFree24 more frequently.

Whilst all substances have a ‘toxicity’ level (even water), Zoono has a ‘toxicity rating’ similar to that of Vitamin C. So yes – Zoono can be safely used around people, pets and plants alike. Unlike traditional sanitisers that kill bacteria by poison or high alcohol content, Zoono is a food-safe, water-based surface sanitiser that works – and keeps working – after it dries

No. Unlike other hand sanitisers that contain up to 70% alcohol (that remove natural oils and dry the skin), GermFree24 is a mild, non-alcohol formulation. On application, Zoono Hand Sanitiser leaves hands soft and silky.

Yes. GermFree24 Hand Sanitiser does not inhibit the normal function of the skin. The antimicrobial layer produced by application GermFree24 Hand Sanitiser bonds to the skin yet allows the skin to “breathe” normally.

Yes. ZOONO is one of the only disinfectant products on the market that can back up its claims with multiple independent lab results. Zoono has approx 150 Test Results on file from accredited laboratories around the world, including New Zealand, Australia, UK, Germany, USA, South Africa, Korea, China and Japan. These are provided as part of the Regulatory process for Approvals and Registrations globally.  ZOONO has been successfully tested against a variety of pathogens and germs including the hospital superbug MRSA, Staph, E.coli, H1N1, MERS, Norovirus, SARS COVID plus many more.  

Yes. Because it’s free from alcohol and other harmful ingredients you can use the Surface Sanitiser Spray to keep germs off toys. Make sure you clean the toys first then spray and let it completely dry before giving it back to them.

Using hand sanitisers, usually containing alcohol (70% to 90%) and many other chemicals cause health problems and skin irritation, especially if you have sensitive skin, are asthmatic or suffer from eczema. Normal hand sanitisers kills germs and pathogens at the point of use and when wet. Once dry, they no longer work, and many don’t achieve the contact time stipulated in their laboratory tests. Traditional alcohol based hand sanitisers lasts only up to 7 minutes on our hands.  ZOONO®’s protective shield has been proven to kill 99.9% of germs and pathogens such as Mould, Yeast, Fungi, Virus and Bacteria for up to 30 days on surfaces and up to 24 hours on the skin.
