SafeSol Multi-Application Disinfectant |
|
SafeSol: Introduction |
The modern ideal
water biocide should be lethal to water pathogens like Legionella
but also relatively safe to use.
Hydrogen Peroxide has been used for decades as a disinfectant but
has not been taken seriously in this role because of its relatively
poor biocidal properties.
It is now known that Hydrogen Peroxide is a chemical that with the addition
of trace components can produce significant changes in the property
of the chemical.
In the early 1980’s Dr Hummerbach, a German
research chemist developed a silver catalysed, highly stabilised
hydrogen peroxide which had dramatically increased disinfecting
properties compared with standard hydrogen peroxide.
SafeSol is the UK product name for a silver catalysed,
stabilised hydrogen peroxide which has been tested and applied in
many commercial and industrial situations across the world, but is
only now beginning to come of age. |
This website presents
some of the unique and interesting features of SafeSol, an eco
friendly chemical that offers significant advantages in many
different sectors.
SafeSol is a clear multi - component disinfectant with a hydrogen
peroxide content of 50% and an ionic silver content of around 320
ppm. Around 8 other trace stabilising chemicals are added to the
chemical to ensure that it has long-term stability. SafeSol is
completely miscible with water in all proportions. SafeSol is a
single component biocide. It does not require an activator. In other
words the product supplied in the drum is the only product required
for system disinfection. |

SafeSol
Germicidal Effect |
|
-
SafeSol is a true no gap disinfectant. It is effective against
all bacteria, viruses, algae and fungi without exception.
-
It is highly effective against gram-positive bacteria, gram-negative
bacteria, pathogens like Legionella, Salmonella, and Listeria, and all
virus groups, sheathed or unsheathed.
-
It is effective against yeasts, spores and moulds.
-
SafeSol is effective against biofilms
the adhesive ecosystem, which attaches itself to pipe and vessel walls.
-
SafeSol can be applied as a surface
disinfectant and as a biocide in a water system. It is generally applied
at a concentration of 1%-2% as a surface disinfectant to clean surfaces,
and at a concentration of 2% -5% to dirty surfaces. The exact
concentration will depend on application.
-
SafeSol is applied to water systems as
a biocide at a concentration of 200ppm for disinfection and at a
concentration of 10 –25ppm in a continuous dosing situation.
-
SafeSol can be used at a concentration of up to 50ppm
(generally 20ppm) in aquaculture situations where there is a risk of
fungal or bacterial attack on fish.
-
SafeSol’s main attributes are that it is very stable (up to
950 C), environmentally acceptable in that it breaks down to
water and oxygen, and destroys and removes biofilm.
|
For many years there
has been a move towards more environmentally acceptable biocides and
disinfectants. Hydrogen Peroxide has been used
as a disinfectant, in
situations where there has been no suitable alternative. While hydrogen
peroxide is a relatively poor disinfectant SafeSol offers considerably
improved disinfecting properties while retaining all the environmental
advantages.
