According to Mark, Biofilm Solutions'
innovative technology has resulted in
the company's Laurinex Health product
recently gaining TGA (Therapeutic Goods
Administration) approval as 'hospital
grade disinfectant for use within the
healthcare industry' in Australia and
New Zealand. He said it also meets all
the regulatory requirements for use in the
Based on research, Mark explains that
90 per cent of bacteria live in biofilm, and
extensive scientific studies have shown
existing disinfectants and sanitisers in use
within the healthcare cleaning industry have
been ineffective in removing biofilm.
"Laurinex provides an exceptional clean
on most hard surfaces and fittings, including
stainless steel, hard floors, fabric, carpets,
concrete, porcelain, rubber, plastic and
aluminium," he said. "For example, it can
clean tile grout back to near new in a matter
of a few minutes."
A study carried out by scientists from the
Healthcare Infection Society in New South
Wales in an intensive care unit in 2011
(Vickery et al), found that multi-resistant
organisms (MROs) continued to be present
on surfaces in a hospital environment after
routine disinfecting and sanitising programs.
According to Vickery et al (2011),
'A biofilm is a structured community
of organisms encased and attached to
a surface by exopolymeric substances
(EPS). The EPS makes up to 90 per cent
of the biofilm providing protection from
environmental desiccation and this EPS
is extremely difficult to remove using
detergents. Additionally, bacteria within
biofilms are up to 1500 times (typically
100 to 250 times) more resistant to
biocides than the same 'planktonic'
bacteria growing in liquid culture.
'Biofilms are generally found in moist
environments, causing infection on
implantable medical devices such as
catheters and breast implants or on
instruments routinely immersed in fluid....
despite the decreased moisture availability
on dry surfaces, bacteria within the ICU
environment also reside in biofilms, and
that within these biofilms, MROs are
protected from physical removal and
Scientific biofilm breakthrough
raises bar for healthcare cleaning
A South Australian company based in Adelaide has introduced a botanically-derived, non-toxic, food-grade product
that will set new standards in removing bacteria and viruses that cause healthcare-associated infections (HAIs).
Lorraine Day interviews Biofilm Solutions' co-founders Mark Losasso and Blair Baxter about this innovative technology.
'Using destructive sampling, followed by
SEM and culture, we have demonstrated
the presence of biofilm and biofilm
containing MROs on clinical surfaces
from an ICU despite terminal cleaning,
suggesting that current cleaning practices
are inadequate to control biofilm
development. The presence of MROs being
protected within these biofilms may be the
mechanism by which MROs persist within
the hospital environment.'
Biofilm Solutions' chief executive officer
Asia and co-founder Blair Baxter said that
until now, no-one has addressed the removal
of biofilm. "It is a significant issue inside
healthcare facilities and hospitals," he said.
"The key to better performance against
HAIs is to incorporate rigorous biofilm
detection protocols and implement new
standards in environmental surface cleaning,
plus introducing solutions which remove
'If you disrupt the EPS you can dislodge
the biofilm, then you remove and kill the
polymicrobial bacteria. No hospital grade
disinfectant cleaning product in use today at
Log 3 has the capability of removing EPS,
let alone dislodging biofilm," he declared.
"Our product, Laurinex Health, is
scientifically proven to be 100, 000 times
greater anti-microbial performance than
sodium hypochlorite (bleach). Bleach, the

current industry health standard is Log
3 bacteria kill whereas Laurinex is Log
10 bacteria kill on hard surfaces, with no
regrowth of bacteria," Blair explained.
Biofilm testing has been carried out in the
United States in world class laboratories
using CDC Biofilm Reactors, confirming the
performance and local Australian testing
using TGA protocols have confirmed a Log
10 kill rate.
"Laurinex Health is a TGA-approved
hospital grade disinfectant that is
environmentally friendly, non-corrosive,
100 per cent biodegradable and doesn't
require a poisons number on the Australian
labelling," revealed Blair.
The patented biotechnology
behind Laurinex solutions is called
Hyperprotonation and is a foundation
pioneering breakthrough with considerably
more scientific studies underway to solve
biofilm-related in the healthcare sector.
The non-toxic all food-grade components
in Laurinex have been shown to defeat
biofilms and eradicate microorganisms
completely; and the solutions are wholly
manufactured in Australia, and registered as
"The difference between our clean and
a standard chemical clean is dramatic,"
stated Blair. "Laurinex Health, which is
our hospital grade and also our commercial
grade Laurinex Trade, are HACCP
approved as a food grade disinfectant,
suitable in food processing plants, for
stainless steel preparation benches and
"Biofilm Solutions has many customers
nationally and has also received enquiries
internationally across healthcare, food
processing and hospitality sectors,
given the dramatic performance of our
products," he shared.
"Because Laurinex is non-toxic, you
don't need dangerous chemical handling
procedures, so patients, healthcare workers
and cleaners using the product, have better
work health and safety environmental
standards," Blair added.
"Laurinex is a game-changer in the
industry. There's been nothing like it since
bleach was invented."
