Sodium Hypochlorite dilution – Hospital grade disinfectants

[Pamela Ann Boon]

Good morning everyone,

I am comparing two Sodium Hypochlorite products for hard surface cleaning/disinfection (floors etc).
They have widely different recommended ppm dilutions for reconstitution as hospital grade disinfection (one is 1000ppm, the other is 5000ppm).

Does anyone have any suggestions where I can locate advice on approximate ppm Sodium Hypochlorite dilution for microbial kill?

Thanks so much,
Kind regards,
Pam

Hi Pam,

Generally in Australia 1000ppm Sodium Hypochlorite is recommended and used
however you will find in the USA Sodium Hypochlorite 5000ppm is general
what is used.

In outbreak control reports (i.e. multiple strategies) you will find both
concentrations of Sodium Hypochlorite noted.

If your including spores in your query find below an extract from the recent
“ASID/ACIPC position statement – Infection control for patients with
Clostridium difficile infection in healthcare facilities” which explains
further the use of chlorine based agent.

. “If using a chlorine based agent (i.e. household bleach) high
levels of chlorine (5000 mg/L free chlorine) have been shown to have
consistent efficacy against C difficile spores however lower dilutions of
chlorine (1000 and 3000 mg/L free chlorine) show varying capacity to
eradicate spores. Sporicidal agent contact times recommended by the
manufacturer/supplier need to be practical for healthcare n settings. Long
contact times (the time the surface needs to remain wet) of 10-30 min may be
an occupational health and safety hazard and are not practical for a
healthcare setting”.

I hope this is helpful.
