The worst removable side products of human activities:
-car exhaust fumes
-cigarette smoke
-organic solvents released from
adhesives,paints and various chemical
processes
-microbes, mildev germs
You can't see them, nevertheless, they
are harmful.
Fig.1 Photosynthesis
of plant:
After the sunlight has been adsorbed, plants will converse
carbon dioxide and water to complex organic molecules
The reverse process is photo-degradation:
Organic substances decompose to elementary ones,
especially water and carbon dioxide.
To start this process a higher light intensity and longer
exposition time are needed.
The photo-degradation is photo-catalytic process.

Photo-catalysers = substances extraordinarily sensitive to light
TiO2 - titanium dioxide known as white pigment.
Its photo-catalytic efficiency strongly depends on particle size and the
method of particle preparation.
The finest TiO2 parts (nano-size) are characterized by a large active
surface.
They are effective mainly in case of an intensive lighting, especially
with UV part of solar spectrum.

Into crystalline structure foreign metal atoms were purposely
introduced (similarly to semiconductors).
On their surface, only minimum light energy release a part
of electrons that will, together with oxygen from the air,
attack all around them very intensely.
Even this may be a reflected light, or artificial light.
Decomposition of gaseous and liquid harmful
substances may thus run even in building interiors
A big amounts of biologically detrimental organisms are
floating in the air all around us, such as microbes,
mildew germs, etc.
In contact with photo-catalyst, the surface of their cells is
strongly attacked so they rapidly die.
The reflected sunlight or artificial light is suffices.
Detoxy Color
is the first paint which is really efficient in
case of both gaseous and liquid pollutants
and has an anti-microbial and fungicide
effect in both daily and artificial light
conditions.
The paint is based on a special photo-catalyst, produced
using own, copyright protected manufacturing procedure.
The determination of photo-degradation efficiency of
Detoxy Color was performed by Institute of Inorganic
Chemistry of the Czech Academy of Sciences in the
testing photo-reactor.
The result is displayed in the graph 1. and 2.
The decomposition of organic pollutants is running with
simultaneous creation of carbon dioxide.

The Czech National Institute of Public Health has tested
the action of Detoxy Color on the most common microorganisms.
The measurement results evidenced that micro-organisms
die on the surface of Detox Coloru within several hours.
The same action mechanism was observed also in case of
mildews monitored.

Detoxy Color may therefore be rightfully classified as a
color which cleans the air.
It decomposes bacilli and germs efficiently, as well as all
aliphatic and aromatic hydrocarbons (propane, butane,
petrol, xylol and benzene) and all dangerous smoking
products.
Detoxy Color is therefore really a meaningful contribution
to environmental protection.
Detoxy Color may be recommended for any place where
humans are exposed to a strong, negative action of
civilization.
DETOXY COLOR ® is suitable for use in hospitals, offices,
consulting rooms and apartments.
Especially in hospitals, where (according to available
statistics ) 7 to 10% of deaths are caused by
confrontations of viruses and weakened organisms, is
Detoxy Color is enormly important
DETOXY COLOR® is the result of the common
research conducted by Rokospol a.s.
Corporation and the Institute of Inorganic
Chemistry of the Academy of Sciences of the
Czech Republic.
