Bucasan D 40 clears EN 14476

Bucasan D 40 has completed virucidal testing to EN 14476, which means it can now be specified for enveloped and non-enveloped virus claims across acute wards, theatres and high-touch furniture. The test report ships with every order and is the document to attach to an audit file.

What the standard actually covers

EN 14476 is the European suspension test for virucidal activity of chemical disinfectants in the medical area. It is deliberately unkind: the test is run under dirty conditions, with an interfering substance standing in for the organic soil a real surface carries. A product that passes has been shown to work through the mess, not just on a clean coupon in a lab.

For Bucasan D 40 the claim holds at the labelled contact time of five minutes, at every dilution in the 1–5% range. That last part matters more than it sounds. A disinfectant whose claim only holds at its strongest dilution is a disinfectant that will fail in practice, because nobody doses at outbreak strength on a Tuesday morning.

Why we went alcohol-free

Alcohol is fast on a clean surface and unreliable on a dirty one. It flashes off before it finishes the job, and the smell in an occupied ward drives staff to open a window and under-dose the bucket. Neither of those failure modes shows up in a lab test; both show up in a facility six months after handover.

The quat and amine system in Bucasan D 40 stays wet for the full contact time and keeps working through light soil. It also lets housekeeping clean an occupied bay without clearing the room, which removes an entire scheduling problem from the ward round.

What changes for existing customers

Nothing about the product has changed — the formulation, the dilution chart and the article number are the same. What has changed is the documentation you can put in front of an infection-control lead. If you already hold stock, the efficacy report covers it.

Sites running a terminal-clean protocol should note that the five-minute contact time applies at the 3% dilution too. Several customers had been holding ten minutes out of caution; that is no longer necessary and it gives a bed back to the ward sooner.
