Over the past few months, Surfachem have received an increase in the number of enquiries for biocidal and sanitation products to help fight the COVID-19 outbreak. As a guide, we’ve collated some of the most frequently asked questions to help support you at this time.
At Surfachem we have a range of rheology modifiers that are commonly used to thicken alcoholic hand sanitisers.
The most common are:
Yes. We recommend using the highest active level you can (preferably SURFAC® TELA PURE 90% AQUEOUS) and neutralising this to pH 7.30 – 7.60. It is important to note that ethanol hand sanitisers are more effectively neutralised with aminomethyl propanol (AMP) or 20% sodium hydroxide solution (NaOH(aq)), however they will still work with SURFAC® TELA.
This video is showing an aloe gel that has already been thickened with a Rheology Modifier. Our aloe gel is not thickened, therefore adding this to IPA will result in a watery, cloudy solution.
Statements such as “kills germs”, “kills bacteria” and/or “antibacterial” can all be used on your labels. However, you should not be making quantitative statements such as, “kills 99.9% of bacteria” or specific kinds of bacteria such as “kills salmonella” without having the relevant EN testing evidence to prove this.
EN tests are EU testing standards for providing evidence of biocidal effect. The most common you will come across are;
Surfachem’s hand gel formulation has passed both EN1276 and EN1500 testing.
IPA has now been inscribed for Product Type 1, but you can apply for a derogation from the HSE under Article 55. This will allow you to continue selling IPA hand sanitisers without having to comply with BPR registration.
