How to spot fake or substandard hand sanitizer
A substandard sanitizer usually gives itself away on the label: no alcohol percentage, no batch number, no expiry date or no manufacturer. Add a suspiciously low price or an unusual smell and you should not buy it. For bulk orders, ask for the batch test result before you pay.

Quick answer
- No alcohol type or percentage on the label is the biggest warning sign.
- Missing batch number, dates or manufacturer name means nobody is accountable.
- A sharp, unusual or fuel-like smell, or cloudy liquid, can signal contamination.
- Never use a product that lists methanol.
Ten checks before you buy
- Alcohol type (ethanol or isopropyl alcohol) is named.
- Alcohol percentage is printed, ideally as % v/v, at least 60% ethanol or 70% isopropyl.
- Batch number is printed, not handwritten.
- Manufacturing and expiry dates are printed.
- Manufacturer or distributor name and address are given.
- Seal or cap is intact and the bottle does not leak.
- Liquid looks clear (unless a gel), with no sediment.
- Smell is of alcohol, not of fuel or something sharp and unfamiliar.
- Price is in line with other labelled products of the same size and strength.
- For bulk: a test result exists for the batch, with matching batch number.
Why weak sanitizer is a real problem
Below about 60% alcohol, a sanitizer may only slow the growth of germs rather than kill them, while people believe their hands are clean. In a clinic, school or food business, that false confidence can do more harm than having no sanitizer at all.
The methanol danger
Methanol is sometimes substituted because it is cheaper than ethanol. It can be absorbed through the skin, and swallowing it can cause blindness or death. Health regulators abroad have recalled many hand sanitizers found to contain methanol. If anyone swallows sanitizer, or develops headache, blurred vision or vomiting after using one, get medical help immediately.
What to do if you suspect a bad batch
- Stop using it and keep the bottle with its label.
- Note where and when you bought it and the batch number.
- Tell the seller and ask for the batch test result.
- Report concerns about substandard products to PSQCA.

Frequently asked questions
Can I test alcohol content at home?
Not reliably. Home tricks such as checking how fast it evaporates or whether it burns are inaccurate and the burn test is dangerous. Rely on the label and a laboratory test result for bulk purchases.
Is a sanitizer that smells strongly of alcohol always good?
No. Smell tells you there is some alcohol, not how much or which kind. Check the label.
Does a famous brand guarantee quality?
A known brand is more accountable, but counterfeit copies of popular brands exist. Buy from traceable suppliers and check the batch details.
