Description
Deicing composition comprising a deicing agent, a native protein and a molasses
The present invention s to a deicing composition and to a process for the
preparation of said deicing composition. It furthermore relates to a process for deicing
a e and to a kit of parts for use in said process. y, it relates to the use of a
combination of a native protein and a molasses for improving the efficiency of a
deicing composition.
Wintry conditions provide eniences to roads and traffic in the form of snow or
black ice. Obviously, eliminating snow, frost, and ice of roads and ys has
enormous benefits for the . Sodium chloride (NaCl) is commonly used to control
snow and ice formation on roadways, highways, and sidewalks. The sodium chloride
works as a deicing agent by dissolving into precipitation on roadways and lowering
the ng point, thereby melting ice and snow. Other salts that can be used as
deicers include for example calcium chloride and magnesium de. These
compounds depress the ng point of water to an even lower temperature than
sodium de. Also potassium chloride is sometimes used as a deicer. Another,
commonly known alternative to road salt is calcium magnesium acetate. Other, less
known deicer salts include potassium acetate, sodium acetate, sodium formate, and
potassium formate.
The wintry conditions also create damage to asphalt, bituminous, and concrete
surfaces. These surfaces have porous structures. Especially asphalt comprises a
number of subsurface channels. When the ound temperature becomes
sufficiently low, an aqueous solution which is present in the channels of the asphalt
will expand upon freezing, thus, creating mechanical stress in the asphalt. Especially
after repeated freezing and thawing, the asphalt will break, resulting in potholes. Not
only large sums of money have to be spent each year to repair damaged roadways
and highways, potholes may also result in dangerous situations for traffic.
Furthermore, the additional maintenance required will result in additional traffic jams.
The problem of damage to ys and highways because of the expansion and
ction of water or water-based solutions during freezing and g cycles has
become an even bigger issue since the introduction of a new type of t, the so-
called highly porous asphalt in the nineties. This highly porous asphalt concrete may
comprise up to 20% of hollow space. This has the advantage that rain and melt water
will flow away quickly from the asphalt surface through the subsurface channels into
the soil. The asphalt road surface itself s practically no moisture, and hence, is
not slick and slippery even in case of heavy rainfall. While the use of this type of
asphalt has an us beneficial effect on safety under rainy conditions, a
disadvantage is that under wintry conditions more of the deicing agent is needed in
order to keep the roads free of snow and ice during the winter as the deicing agent
will also flow away with the melt water from the road surface.
It is an object of the present invention to provide a deicing composition which has
improved deicing properties. More particularly, it is an object of the present invention
to provide a deicing composition which remains effective over a longer period of time
so that the deicing agent can be applied less frequently and the damage to especially
highly porous road surfaces will be reduced even after repeated freezing and
thawing. The foregoing s should be read disjunctively with the object of at least
providing the public with a useful choice.
Surprisingly, the objective has been met by adding a combination of two types of
additives, viz. a protein and a molasses, to a deicing agent. in more ,
the present invention relates to a deicing composition sing (i) a deicing
agent selected from the group consisting of sodium chloride, calcium
magnesium acetate, calcium chloride, ium chloride, potassium
W0 2012/168206
chloride, potassium acetate, sodium acetate, sodium formate, and potassium
formate, (ii) native protein, and (iii) a molasses (with the proviso that
components (ii) and (iii) are not the same).
It was found that the deicing composition according to the t invention
has an ed mance. It has been found that by using the specific
ation of es and native protein, the deicing agent will remain
active over a longer period of time. Furthermore, due to better adhesion
properties of the deicing composition compared to use of the deicing agent
alone, less deicing agent will be blown away and the deicing agent is retained
on the road for a longer period of time.
In addition, it was found that the use of the deicing composition according to
the present invention reduces damage to road surfaces after repeated
freezing and thawing.
The deicing ition according to the present invention has been found to
be less corrosive than conventional deicing compOsitions.
The deicing agent present in the deicing composition according to the present
invention is selected from the group consisting of sodium chloride, calcium
ium acetate, calcium chloride, magnesium chloride, potassium
chloride, potassium acetate, sodium e, sodium formate, and potassium
formate. Preferably, however, the deicing agent is a de salt, i.e. it is
preferably selected from the group consisting of sodium chloride, calcium
chloride, magnesium chloride, and potassium chloride. More preferably
m chloride is used as the deicing agent in the compositions according to
the present invention. Most preferably, sodium chloride is used as the deicing
agent in the compositions according to the present ion as it is cheap
and available in large quantities.
If the deicing composition is an aqueous composition, the deicing agent is
preferably present in an amount of at least 5% by weight, more preferably at
W0 2012/168206
least 10% by weight and most preferably at least 20% by weight (based on
the total weight of the deicing composition). Preferably, such aqueous deicing
composition comprises at most the saturation concentration of the deicing
agent. The deicing composition according to the t invention can also
be in the form of a slurry, containing deicing agent at concentrations higher
than the saturation concentration. If the deicing composition is in the form of a
solid, it may comprise as little as 5% by weight of deicing agent (based on the
total weight of the deicing composition), if it is, for example, mixed with gritting
material like sand. However, preferably, the deicing composition according to
the present invention comprises at least 50% by weight of the deicing agent,
yet more ably at least 70% by weight, and most preferably at least 96%
by weight of the deicing agent (based on the total weight of the deicing
composition).
The protein present in the deicing composition according to the present
invention is a protein which is in its native form. In other words, it is a non—
denatured protein. As the d person knows, proteins (or rather
polypeptides in general) can lose their secondary and ry structure if
exposed to chemical, physical, or mechanical stress, such as a strong acid or
base, urea, an organic solvent or heat. Proteins that are denatured under
such harmful circumstances are no longer suitable for use in the deicing
composition according to the present invention as they have lost their
iveness. ingly, with the terms “native protein” and “protein in its
natural state” it is meant that the protein has not been altered under
denaturing ions such as heat, als, enzyme action or the
exigencies of tion.
For the sake of clarity it is noted that the protein is not a protein as present in
molasses.
The protein le for use in the composition ing to the present
invention is preferably a protein selected from the group consisting of soy
W0 2012/168206
based proteins, dairy based proteins, egg proteins and combinations f.
In one ment, for example, the protein is spray dried egg white powder
or yolk from eggs, or es thereof.
The n is typically present in the g composition according to the
present invention in an amount at least 10 ppm, more preferably at least 100
ppm and most preferably at least 500 ppm. It is preferably present in an
amount of less than 10.000 ppm, more preferably in an amount of less than
8.000 ppm and most preferably, in an amount of less than 5.000 ppm.
The protein concentrations are expressed in ppm, herewith defined as mg
protein per kg of the total deicing composition.
The molasses to be t in the deicing composition according to the
present invention can be any molasses conventionally used for deicing
purposes. It is noted that it is le to use molasses which have been
subjected to one or more purification steps, such as the removal of
sulphites, sulphur dioxide, ash, microbial life forms or other insolubles as
removal of these contaminants does not have an adverse effect on the
performance in the deicing composition. It is furthermore noted that it is
possible to use chemically, biologically, physically or otherwise treated
molasses, such as, but not exclusively, desugared beet es,
acid/base treated molasses, carboxylated molasses (wherein the sugars
t in molasses are carboxylated with conventional techniques), and
molasses containing one or more additives. Preferably, the molasses is
selected from the group consisting of molasses derived from corn (syrup),
molasses derived from sugar beet, molasses derived from sugar cane and
molasses derived from grapes.
The term “molasses" es all the above types of treated or untreated
molasses.
W0 2012/168206
Preferably, the es is beet or cane sugar es containing between
and 80 wt% , yet more preferably containing between 40 and 60
wt% sugars, most preferably between 45 and 55 wt% sugars.

All samples were ed following the above exemplified principle.
All s had the exact total weight of 30 grams, contained in a Greiner
tube (PP, 50 mL, r BioOne).
mental conditions
These Greiner tubes were stored in the fridge for maximum 2 days until the
start of the experiment. Upon starting the experiment, the tubes were stored
in the freezer at -29°C and evaluated by eye for their solids content, with an
accuracy of 5—10% per sample. The evaluation of solids content was done
by eye, implying the tion of solids content with respect to the total
volume of the sample. All samples were prepared in three-fold and the
presented solid contents are calculated as the average of all three samples.
Results
Table 1 is a matrix representation of all combinations of proteins and
molasses tested at different concentrations. Molasses is arranged
ntally, with the leftmost column showing the samples without
molasses. The proteins are ed vertically, with the uppermost row
showing the samples without proteins. In the grey bars, the concentrations
of the corresponding additives are given in ppm (mg/kg). All numbers in the
white area represent the solids content after 24 hours.
W0 2012/168206
The reference samples containing either a protein or es do always
show high solids content, gh not always 100% solids. However, after
longer time all these reference samples completely solidified without
exception. All other samples comprising both a protein and molasses do not
solidify completely, if at all. In all cases the solid content is much lower than
that of their respective references. From this table it can be derived that
there is y between proteins and molasses.

All Figures show the synergy between proteins and molasses. All grey dashed lines
(samples containing only one ent) go up quickly to 100% solid content,
whereas all black solid lines (samples containing a mixture of protein and molasses)
stay well below all grey dashed lines.
Proteic material naturally present in compositions comprising molasses (such as
te) clearly has no contribution to keeping brines liquid at very low
temperatures. The addition of very little amounts of native protein (10 ppm) y
leads to the synergistic effect (see Table 3, Table 4).
