Frequently Asked Questions

How does biofree® work?

Most recently, questions have been focused on SARS-CoV-19, a virus.

Alcohol hand rubs work by dissolving the fatty outside layer of the virus, leading to damage of the virus’s protein structure through denaturation.

So why not 100% alcohol?

Water is also an important part of the formula, with many studies having demonstrated that alcohol on it’s own is less efficient than a water/alcohol mix.1

What percentage of alcohol is biofree®?

biofree® is 75% alcohol.

How do I know biofree® is effective?

biofree® has been tested by healthcare professionals across the world. The microbicidal activity of the WHO-recommended formulation was tested by WHO reference laboratories according to EN standards (EN 1500)2. This ensures its effectiveness as a product.

Why is biofree® a liquid and not a gel?

The World Health Organisation have recommended a liquid sanitising product. This is due to a number of reasons such as economic cost, availability of ingredients, ease of production and versatility of use. Although both gels and liquids are effective, the addition of gelling agents/ additional ingredients would mean the product could not be used for surgical hand preparation (another recommended use of the formulation).

Does this product have a shelf life?

The shelf life of this product is two years. Sanitisers past their expiration date can be less effective, or completely ineffective due to the dropping level of alcohol in the product over time. The product does not become dangerous at this point, simply less able to kill viruses and bacteria.
