Modified Alkoxylated Polyol Compounds
FIELD OF THE INVENTION
This invention relates to modified alkoxylated polyol compounds, methods of
making
modified alkoxylated polyol compounds, and cleaning compositions comprising
the same.
BACKGROUND OF THE INVENTION
Polyol compounds such as sugars like sucrose or maltitose are known as a
sustainable and
readily available raw material. Ethoxyates of maltitol is known, e.g., CAS
503446-80-8. This
material has been widely disclosed as a surfactant for cosmetic and other
personal care
applications such as that discussed in JP 2003-096182. Other known ethoxylated
polyols
include: ethoxylated manitol (CAS 53047-O1-2), ethoxylated inostol (CAS 503446-
79-5),
ethoxylated sorbitol (CAS 53694-15-8). JP 10-081744 discusses the production
of
polyetherpolyols by adding alkylene oxides to saccharide in the presence of
amine catalysts.
However, as "catalyst" implies, the amine catalysts do not become incorporated
into the
polyetherpolyol structure.
Also known are a series of amine terminated ethoxylates known in the trade as
JEFFAMINES~ sold by Huntsman. These are mainly derived from polyethylene
glycol and
mixtures of polyethylene glycol and polypropylene glycol where the glycols are
aminated
directly with ammonia and a catalyst. These are called JEFFAMINE D~ and
JEFFAMINE ED~
series. The most complex mixture of the JEFFAMINES~ series is the T series.
The
JEFFAMINES~ are based on either trimethylolpropane or glycerine and thus have
three
ammonia terminated ethoxy/propoxy branches radiating from the glycerin or
trimethylolpropane
core.
Amination of polyols with ammonia and other amines is further exemplified in
US
5,371,119, but uses modification of the polyol specifically via
epichlorohydrin to form a polyol
bis-halohydrin followed by reaction with ammonia or an amine to form repeating
networks of
amino polyols. This results in formation of a complex polymerized mixture
containing multiple
polyols linked randomly via the reactive halo hydrin. This complex mixture is
not believed to be
of value to formulators of cleaning compositions fox the purpose of providing
cleaning benefits
and is targeted towards forming emulsifiers.
Simple amination ofpolyols are described in WO 01/98388 A1 discussing simple
aminated
polyols, further reacted with aldehydes, in particular formaldehyde, to make
complex polymeric
networks. Included in these complex structures is the ability to have sulfide,
carboxylate, alkyl
esters, alkyl sulphonates, and alkyl phosphates as a functional unit of the
complex structure.

However, the resulting complex polymeric networks is not believed to be of
value to formulators
of cleaning compositions for the purpose of providing cleaning benefits.
Additionally, it has not
been taught to manipulate these materials in a controlled and specific manner.
Selective
modification of sugar derived polyols to provide modified polyols where the
star like structure is
tuned to meet the needs of detergent formulators is highly desirable.
There also exists a need for materials that are relatively easy to manufacture
from
sustainable and readily available raw materials, which may be broadly tuned to
address specific
performance requirements. .
Stressed conditions also give the additional problem of having anionic
surfactants such as
linear alkylbenzene sulfonates or alkyl sulfates form larger order aggregates.
The aggregation of
the anionic surfactant reduces the amount of the anionic surfactant available
to clean.
There exists a need fox materials that are relatively easy to manufacture from
sustainable
and readily available raw materials, which may be tuned in a controlled and
specific manner to
address specific formulability and performance requirements. A multifunctional
material that
provides cleaning and gives increased surfactant availability by preventing
formation of larger
ordered aggregates of anionic surfactant with free hardness during use is
desired.
Specific performance requirements include providing cleaning of hydrophobic
stains
(grease, oil) to hydrophilic stains (clay) associated with outdoor soils.
Other performance
requirements include used in personal care compositions, such as contact lens
solution, uses in
adhesives, vulcanization of rubbers, use in polyurethane processes, use as dye
additives, use as a
dispersant in agricultural applications, use as dispersants for inks, asphalt
dispersants, surfactant
dissolution aides, in use surfactant solubilizers in presence of calcium and
magnesium among
other performance requirements.
Formulability of some of the current commercial polymers, which provide
cleaning of
outdoor soils, into granular and liquid laundry detergents, hard surface
cleaners, dish cleaning
compositions, personal care compositions as well as oil drilling compositions
continues to
challenge detergent formulators.

comprises the step
of reacting the alkoxy moiety of the alkoxylated polyol with at least one
anionic capping unit
containing as least one of the following anionic groups; sulfate, phosphate
and carbonate; to form
an anionic alkoxylated polyol. The process may partially or completely react
the alkoxy moiety

Scheme II is distinguished from Scheme I in two areas; (1) direct substitution
of the terminal
hydroxy moieties is accomplished by catalytic oxidationlreduction using metal
catalysts and
hydrogen; (2) sulfation is carried out after amination and quatemization by
transulfation as
disclosed in LTS 6,452,035. A zwitterionic alkoxylated polyol of the same
composition may be
prepared by either Scheme I or Scheme II above. One of skill in the art will
recognized that other
amine capping units may be used, including but not limited to ammonia or
dimethylaminopropylamine.
A specific description of the process of the present invention is described in
more detail
below.
Ethoxylation of Polyol
Ethoxylation of the polyol, such as sorbitol, may be completed by any known
technique,
such as that described in EP 174436 A1 Propoxylation and butoxylation may also
be completed
by known techniques.
Add sorbitol (17.5g, 0.0962 mol) to an autoclave, purge the autoclave with
nitrogen, heat
sorbitol to 110-120°C; autoclave stirred and apply vacuum to about 20
mmHg.
Vacuum is continuously applied while the autoclave is cooled to about 110-
120° C. while
introducing 6.2g of a 25% sodium methoxide in methanol solution (0.0288 moles,
to achieve a
5% catalyst loading based upon hydroxy moieties). The methanol from the
methoxide solution is
removed from the autoclave under vacuum. A device is used to monitor the power
consumed by
the agitator. The agitator power is monitored along with the temperature and
pressure. Agitator
CA 02549571 2006-05-31
WO 2005/063847 PCT/US2004/043074
power and temperature values gradually increase as methanol is removed from
the autoclave and
the viscosity of the mixture increases and stabilizes in about 1.5 hours
indicating that most of the
methanol has been removed. The mixture is further heated and agitated under
vacuum for an
additional 30 minutes.
Vacuum is removed and the autoclave is cooled to or kept at 110° C.
while it is being
charged with nitrogen to 1725 kPa (250 psia) and then vented to ambient
pressure. The autoclave
is charged to 1380 kPa (200 psia) with nitrogen. Ethylene oxide is added to
the autoclave
incrementally while closely monitoring the autoclave pressure, temperature,
and ethylene oxide
flow rate while maintaining the temperature between 110 and 120° C. and
limiting any
temperature increases due to reaction exotherm. After the addition of 483g of
ethylene oxide
(10.97 mol, resulting in a total of 19 moles of ethylene oxide per mol of OH),
the temperature is
increased to I20° C. and the mixture stirred for an additional 2 hours.
The reaction mixture is then collected into a 22 L three neck round bottomed
flask purged
with nitrogen. The strong alkali catalyst is neutralized by slow addition of
2.8g methanesulfonic
acid (0.00288 moles) with heating (110° C.) and mechanical stirring.
The reaction mixture is then
purged of residual ethylene oxide and deodorized by sparging an inert gas
(argon or nitrogen) into
the mixture through a gas dispersion frit while agitating and heating the
mixture to 120° C. for 1
hour. The final reaction product, approximately SOOg, is cooled slightly, and
poured into a glass
container purged with nitrogen for storage.
Alternatively, polyol may be purchased with a degree of alkoxylation that is
at or below
that desired, such as CAS S262S-13-S, a propoxylated sorbitol or sorbitol
polyoxy ethylene ether
available from Lipo Chemicals Inc. Wherein the desired degree of alkoxylation
is achieved by
the processes known and/or described above.
Sulfation of Sorbitol EO,~d (Average of 19 EO moieties per hydroxy moiety)
Weigh into a SOOmI Erlenmeyer flask Sorbitol El4 (299.7g, O.OS8 mol) and
methylene
chloride (300g) ("the solution") . Equip the flask with a magnetic stirring
bar and stir until
complete dissolution. Place the flask in an ice bath until the solution
reaches about 10°C. Stir
vigorous while slowing pouring chlorosulfonic acid (48.3g, 0.415 mol) over the
period of about S
minutes to form a reaction solution. Stir the reaction solution in the ice
bath for 1.5 hours.
Place a solution of sodium methoxide (197g of 2S% in methanol) in SOg of
methylene
chloride in a IL Erlenmeyer flask ("base solution") and chill in an ice bath
until the temperature
of the solution reaches about 10°C. Stir the base solution vigorous
using a magnetic stirring bar.
Slowly pour the reaction solution into the base solution over a period of
about 3 minutes. A mild
exotherm should be observed. The resulting solution becomes milky as salts
form. After addition
is complete, measure the pH to be about 12. Add to this resulting solution
about 100 ml of
distilled water, and transfer the resulting emulsion to a 1L round bottom
flask and use a rotary

evaporator at 50°C to strip, in portions, to obtain a clear solution.
Transfer the clear solution to a
Kulgelrohr apparatus. At 60°C and 133 Pa (lmm Hg) strip the solution to
yield 366g of off white
waxy solid, 90% active (10% salts).
Carbon NMR spectrum (500 MHz; pulse sequence: s2pul, solvent D20; relax. delay
0.300 sec, pulse 45.0; acq. time 1.090 sec) shows an absence of alcohol groups
at about 60ppm
and the emergence of a new peak at about 67ppm consistent with formation of
the end group
sulfate. Proton NMR spectrum (500 MHz or 300 MHz; pulse sequence: s2pul,
solvent DzO;
relax. delay 1.000 sec, pulse 45.0; acq. time 2.345 sec) shows a new peak at
about 4ppm which
was integrated against the ethoxy group protons at about 3.Sppm and is
consistent with the
molecule having 6 end group sulfates.
Example 2: Amination of Sorbitol EO"n Hexasulfate Of Example 1
Weigh into a 200m1 glass liner sorbitol EO"4 hexasulfate (61.3g of 90% active,
