About #BYOBclean hand sanitiser

1. What is in the sanitiser? Is it safe and effective?
The sanitiser is water-based, with BKC or Benzalkonium Chloride (0.054%), and Polymeric Biguanide Hydrochloride (0.004%) as its active ingredients. BKC at 0.05% is effective against germs including coronaviruses.

This sanitiser is biodegradable. It has no alcohol, It is not flammable, not toxic, and not corrosive.

It is a safe disinfectant for your skin.

Keep away from children.

Do not apply to the eyes, nose or mouth. Do not drink it.

If you have rashes or allergies from frequent use, stop using it, and see a doctor if necessary.

2. How do I use it?
Spray or pump enough to rub all over your hands. Rub until dry, for at least 20 seconds and leave on. Re-apply every few hours if you wish.

3. Is there an expiry date for the sanitiser?
It is best to use within 6 months, as it is filled in a recycled bottle.

The cleaner your bottle, the longer the sanitiser will be good for. Dirty bottles reduce and shorten the effectiveness of your sanitiser. 

Commercial sanitisers bottled in sterile conditions are typically good for at least 4 years.

When you no longer need it, empty and crush your bottle for recycling.

4. How should I store the sanitiser?
Store it in a cool, dry place. Do not mix it up with drinks or other household liquids, and keep away from children.

5. Are these hand sanitisers coming from our national stockpile?
The santisers are not from the national stockpile.



1. May I collect outside of my allocated date?
From 23 to 29 March, you can collect your hand sanitiser from any Community Centre/Club and participating CapitaLand malls.
Your pamphlet is colour coded for the day of collection, to avoid overcrowding. Priority will be given to those whose pamphlets match the day’s colour. For others holding different colour-coded pamphlets, you may have to wait a little longer to collect your sanitiser, and if there is a queue, you may be asked to come back another time to avoid crowding at the collection centres.
If you have missed your allocated collection from 23 to 29 March, you can still collect from 30 March to 5 April at any participating CapitaLand mall.
The last day of collection is 5 April at any participating CapitaLand mall.

2. May I collect on behalf of my friends or family?
Yes, please bring their pamphlets along to collect on their behalf.
Each pamphlet entitles you to 500ml of hand sanitiser.

3. I lost my collection slip. May I still collect?
Please call the hotline at 1800 738 2000 (16 March - 5 April 2020) if you need any help.

4. Is this on a first-come-first-served basis?
We have enough to supply 500ml of hand sanitiser for every household in Singapore. There is no danger that we will run out before you collect, but this is also why everyone needs to bring their pamphlet with them to collect.

5. On the day of collection, are there any documents to bring along for verification?
All households will receive a collection pamphlet with collection details and other key information. 
To collect the hand sanitiser, you can just bring the pamphlet along to the collection centre, along with a clean bottle.

6. How will I know if this is my bottle of sanitiser?
Before filling your bottle, we will paste a special label to identify your bottle of hand sanitiser.

7. How much hand sanitiser can we get? Can I take more if I have more people in my household?
Each household will receive a collection pamphlet which entitles you to collect up to 500ml of free hand sanitiser.

8. Can I pay to buy from you if I need more than what is provided?
The #BYOBclean initiative distributes up to 500ml of free hand sanitiser to each household to help Singapore residents stay safe and healthy. 
The free sanitiser is not for sale or resale.
500ml of sanitiser can typically last for about a month for a small household (4 persons).


1. What kind of bottles should I bring?
You are recommended to bring:
- Shampoo/liquid soap bottles, with a dispenser pump or
- Any plastic, PET or glass bottle, with a leak-proof cap.

2. How should I clean my bottle?
Wash, rinse and dry the bottle thoroughly, especially the cap or pump area before removing any existing labels on your bottle.

3. May I bring bottles of different sizes instead of a single 500ml bottle?
You may bring up to 5 clean bottles with capacity of at least 100ml each. We are sorry that we are unable to accommodate requests for smaller bottles, or more than 5 bottles.

4. Why do I need to bring my own bottle? What if I do not have a bottle?
To encourage all of us to be environmentally-conscious, we hope everyone can repurpose and re-use their own bottles. Any PET bottle such as mineral water bottles or shampoo bottles can be used for collection.
You can also check if your family, friends or neighbours have extra bottles to share with you.



1. Why is Temasek Foundation doing this?
The #BYOBclean project is part of Temasek Foundation’s Stay Prepared initiative to prepare for emergencies and build the community resilience of people in Singapore so that we can all be ready to respond and work together to minimise the impact of emergencies.
To ensure that people in Singapore, especially those in the frontline, stay prepared during this critical period, Temasek Foundation is working with partners to provide free hand sanitisers to the public.

2. What should I do if I do not need the sanitiser?
If you do not need the sanitiser, do consider giving the pamphlet to a friend or neighbour whom you think needs it more.

3. Is it safe to be gathering among crowds at the collection centres?
Volunteers at the collection centres will have their temperature taken before and after their shifts.
The collection schedules are planned such that the crowds at the collection centres are kept manageable and to avoid any overcrowding.
If you are feeling unwell, please see a doctor and rest at home.
Social distancing will also be practiced at the collection centres.  If you come to the collection centre on a day other than your designated one, and there is a queue, you may be asked to come back another time to avoid crowding at collection centres.

4. Who can I call if I have more questions?
You can call the #BYOBClean hotline at 1800 738 2000 from 16 March – 5 April 2020 if you need any help. The hotline operates daily from 9am to 9pm.

  • European Centre for Disease Prevention and Control interim guidance for environmental cleaning in non-healthcare facilities exposed to SARS-CoV-2


The coronavirus that causes COVID-19 might have a stronghold on newspaper headlines, but the truth is, it is pretty vulnerable.


Coronaviruses are “enveloped viruses”, which means they have a delicate coating of lipids (or fats) and protein spikes that surround their genetic material. While this coat may play a role in helping the virus infect cells, it can be easily destroyed by soap or disinfectants, inactivating the virus.

That is why hand sanitisers typically contain active ingredients that target that envelope – if you can’t get to soap and water, you can still disable the virus on your hands before it gets a chance to come into contact with your face.

To kill a coronavirus

Not all germ-killers are created equal. If you would like to check if yours is doing its job, the National Environment Agency’s interim list of “Household Products and Active Ingredients for Disinfection of the COVID-19 Virus” is a good first stop. It is based on published scientific studies on active ingredients that work against coronaviruses, and in the necessary concentrations.

In addition to ethyl alcohol (70%) and isopropyl alcohol (50%), the list includes non-alcohol ingredients like povidine-iodine (1% iodine)benzalkonium chloride (0.05%)chloroxylenol (0.12%), and sodium hypochlorite (0.05-0.5%).

But while all of them might work against coronaviruses and can be found in everyday household cleaning products, not all of them are ideal for splashing on your hands. Some of the active ingredients work better, for instance, in surgical settings, or as surface cleaners.

Povidine-iodine (1% iodine) or iodine in iodophors (50ppm) are commonly used pre- and post-surgery. They stain the area that has been cleaned, letting surgeons know which part of the patient’s skin is sterile. They are also known to provide a disinfecting effect that lasts the duration of most surgeries. Chloroxylenol (0.12%), too, is commonly used as a skin disinfectant and wound cleaner in surgical settings.

The brown stain from iodine-based sanitisers marks the area of skin that has been sterilised.

On the downside, a sanitiser that stains may not be ideal for daily use, and chloroxylenol could irritate the skin and be toxic to pets. Similarly, sodium chlorite (0.23%) and sodium hypochlorite (0.05 – 0.5%), commonly found in household bleaches, are tough on germs, but corrosive on skin.

Deadly for coronaviruses, safe for kids

A common active ingredient in non-alcohol hand sanitisers is benzalkonium chloride (0.05%), or BKC, which kills microorganisms or stops their growth. BKC is also found in wound cleaners, disinfecting wet wipes, lozenges, mouthwashes, and spermicidal creams, as well as spray disinfectants for hard surface sanitisation.

BKC is part of a family of active ingredients called Quaternary Ammonium Compounds, or “quats”, which, in concentrations of at least 0.05%, cause the lipid “skin” of coronaviruses to break and its cell contents to spill out, inactivating the virus, explains infectious disease specialist Dr Leong Hoe Nam.

“Alcohol has been traditionally used, and has become the de facto ingredient (in hand sanitisers) because so many companies use it, but BKC can also kill coronaviruses,” he says, adding that it is important that consumers familiarise themselves with which active ingredients work, and how quickly.

While BKC does takes longer to dry than alcohol, quats’ germ-killing power for some types of bacteria can linger on the hands for hoursBKC is also non-toxic to children and pets, and less likely to dry or irritate skin since it is gentler on the skin’s natural oils. It is also non-flammable, making it easier to store and safe for use in spaces like kitchens.

But whatever sanitiser you choose, do know that none of them work well on greasy, dirty hands. Nor can they effectively remove some chemicals and viruses like the norovirus, which is a hardier, non-enveloped virus that causes gastrointestinal issues, or spores from bacterium such as C. difficile.

And while hand sanitisers offer a reasonably quick coronavirus kill, the inactivated virus remains on your hands. That’s why proper hand-washing with soap should always be your first choice for a complete kill-and-clean, says Dr Leong.

“Sanitisers are convenient to use but for viruses, nothing beats washing it down the sink.”

  • Allhealth Solutions, the distributor of the liquid concentrate present in the sanitiser solution
  • National Environment Agency Interim List of Household Products and Active Ingredients for Disinfection of the COVID-19 Virus
  • European Centre for Disease Prevention and Control interim guidance for environmental cleaning in non-healthcare facilities exposed to SARS-CoV-2

Over the last few months, fear has spread around the globe as quickly as the SARS-COV-2, the coronavirus that causes COVID-19. It has sparked panic-buying of hand sanitisers and anti-bacterial wipes for a quick hygiene fix. Yet, few understand what it is that gives these products the ability to disable germs like coronaviruses.

The strength of sanitisers lies in having the right active ingredients, in the right concentration. According to guidelines from Singapore’s National Environment Agency as well as the European Centre for Disease Prevention and Control, disinfectants with at least 0.05% benzalkonium chloride or 70% ethyl alcohol are effective against coronaviruses. Both target the virus in a similar way.

Coronaviruses have an “envelope”, or a membrane of lipids, or fats, in addition to the protein spikes that give them the “corona” in their names. That protective layer helps the virus survive and spread. Fortunately, that lipid skin is also vulnerable – if it is broken or dissolved, the virus becomes inactive, much like a popped balloon.

Good old soap and water is the best combination to do this effectively. The next best option is to use a hand sanitiser with the active ingredients mentioned.

Alcohol-based hand sanitisers are commonly found in hospital settings, because at concentrations of over 60%, alcohol effectively kills a wide range of microorganisms, including bacteria and some viruses. According to local infectious diseases specialist Dr Leong Hoe Nam, this makes them a quick and effective way to protect frontline healthcare workers who meet many patients every day, thus helping to minimise the transmission of microorganisms to patients.,.

For day-to-day use, however, hand sanitisers with other active ingredients, like benzalkonium chloride, or BKC as it is more commonly known, are effective as well, he says.

BKC belongs to a family of active ingredients called Quaternary Ammonium Compounds, or “quats”, which, like alcohol, ruptures the outer membrane of the coronavirus, causing the cell contents to spill out. BKC is used in everything from lozenges and mouthwashes, to spermicidal creams and surface cleaners. Concentrations differ according to the product – in hand sanitisers, 0.05% can render coronaviruses inactive.

When applied to skin and surfaces, sanitisers require time to work. Alcohol takes 15 to 20 seconds, while BKC can take longer. But because alcohol works by drying or desiccation – the same reason it dries skin out – it’s easier to sense when it is done, as opposed to counting down, says Dr Leong. You should also wait till a non-alcohol sanitiser dries before touching your face.

Non-alcohol sanitisers have their own advantages. BKC-based sanitisers, for example, are non-toxic, so they are particularly suitable for little hands that might find their way into little mouths, or if you are worried it might be ingested by your pets. It can also be less drying to the skin – alcohol can strip the skin of sebums and essential oils, necessitating the use of lotions or creams to rehydrate your skin.

Some studies have shown that benzalkonium chloride can have a longer-lasting effect. It is also non-flammable, making it safe to store and use anywhere.

Both types of sanitisers, however, do come with limitations. Some viruses like norovirus are not easily killed by either, and they do not work when your hands are too greasy or grimy. And as Dr Leong points out, nothing is cheaper and more effective at killing a wide range of viruses than the combination of soap and water.

However, both alcohol and non-alcohol sanitisers can help keep coronaviruses well at bay if soap and water are not readily available. Just make sure you have one with the right active ingredients, and you’re in good hands.

We thank all our partners for supporting #BYOBclean to prepare and distribute free hand sanitisers to all households in Singapore.
