Novel mixtures of sugar amides or sugar amines are disclosed that have improved thermal properties over the individual components.
Surfactants are the single most important cleaning ingredient in cleaning products. Environmental regulations, consumer habits, and consumer practices have forced new developments in the surfactant industry to produce lower-cost, higher-performing and environmentally friendly products. Examples of developments in the surfactant industry are described by J. Scheibel in the Journal of Surfactants and Detergents, “The Evolution of Anionic Surfactant Technology to Meet the Requirements of the Laundry Detergent Industry,” volume 7, number 4, October, 2004 (“Scheibel JSD Article” hereinafter). Today, challenges facing the surfactant industry include colder wash temperatures, less efficient builders, liquid products without calcium control, and a push for reduced surfactant use overall because of the perceived environmental impact of surfactants.
Sugar amide surfactants were commercialized and used by Procter & Gamble for a number of years in various consumer products. See Chemical Economics Handbook Marketing Research Report, Janshekar et al, “Surfactants, Household Detergents and Their Raw Materials”, June 2010, 43. They were based on existing feedstocks available at that time such as coconut and palm kernel oils and glucose as the sugar source for the n-methylglucamine. The physical properties of pure sugar amides can be found in literature references; see Zhu et al, Journal of Surfactants and Detergents, Vol. 2, No. 3, July 1999, pp 357-362, (“Zhu et al” hereinafter). Previously commercialized sugar amide surfactants based solely on glucose and the methyl esters of coconut and palm kernel oils suffered from high thermal properties such as melting point and Krafft point, which limited the true potential of the surfactant for broader application in consumer products. See also Laughlin et al, Surfactant Science Series (1998), 74 (Novel Surfactants), 1-30 and Laughlin et al, Surfactant Science Series (2003), second ed., 114 (Novel Surfactants), Chapter 1, 1-36.
It has now been discovered that new feedstocks based on both the surfactant tail as well as the sugar head group allow for improved physical properties of sugar amide surfactant mixtures and thus improved formulatability. New cellulosic sugar mixtures can give novel and improved sugar amines and sugar amide surfactants with improved thermal properties. Furthermore new sources of unique methyl esters from both bioengineering and or co-metathesis of fats and oils can also provide novel and improved sugar amide surfactant mixtures.
Furthermore, there is a desire by consumers for sustainable products and ingredients. The current existing sustainable surfactants have limitations in terms of formulatability, cost and formulation flexibility. Thus there is a need for high performing sustainable surfactants in the marketplace with improved properties over the existing materials.
The present invention provides a novel mixture of sugar amides or sugar amines that have improved thermal properties over the individual components. The mixture comprising a first chemical and a second chemical, wherein said first chemical has the chemical structure of Formula I and said second chemical has the chemical structure of Formula II:

Sugar Amides and Amines
Sugars suitable for making a mixture of sugar amides or sugar amines can come from a variety of sources. Glucose can be derived from starch, the disaccharide sucrose or cellulose. Xylose can be derived from xylans or from the hemicellulosic portion of a lignocellulosic material. Sugar amides or sugar amines made from these individual sources can then be combined together to provide a mixture of sugar amides or sugar amines.
Alternatively, the sugars can come from a single source such as a lignocellulosic material. Lignocellulosic materials containing both cellulose and hemicellulose can provide both glucose and xylose for reaction into mixed sugar amines and mixed sugar amides. Suitable lignocellulosic materials include wood and wood residues from hardwoods and softwoods; crops, energy crops, agricultural residues and grasses such as wheat, straw, switchgrass, sorgum, bagasse, and stover; or wastes such as industrial or municipal solid waste.
Alternatively, the sugars can come from a combination of sources including a primarily glucose containing source such as starch and a mixed sugar containing source such as a lignocellulosic material for example, wheat.
Other groups besides a fragment derived from sugar are attached to the nitrogen atom. In Formula I and Formula II, R1 and R3 are independently selected from hydrogen, C1-C16 alkyl, C1-C3 hydroxy- or methoxy-alkyl while R2 and R4 are independently selected from hydrogen, C1-C16 alkyl, C1-C3 hydroxy- or methoxy-alkyl, or a structure of Formula III.

In another embodiment of sugar amides, the ratio of the first chemical (based on Formula I) to the second chemical (based on Formula II) is from 50:50 to 0.5:99.5 in the mixture, n1 is equal to 4, n2 is equal to 3, R1 and R3 are methyl groups, and R2 and R4 have the structure of Formula III and R5 is a mixture of C11 and C13 alkyl, wherein the weight ratio of C11 to C13 alkyl is between 99:1 and 60:40. The chemical fragment in Formula I not including the nitrogen atom, R1 or R2 has 6 carbon and 5 oxygen atoms. This chemical fragment can be derived from a six carbon sugar including but not limited to glucose, mannose or galactose. The chemical fragment in Formula II not including the nitrogen atom, R3 or R4 has 5 carbon, and 4 oxygen atoms. This chemical fragment can be derived from a five carbon sugar or polyol including but not limited to xylose or arabinose and mixtures thereof. Suitable sources of the fatty esters required to make the sugar amide compositions to provide the structure of Formula III can come from any of the following sources: triglycerides, fatty acids, fatty esters, bioengineered fatty acids or esters, or synthetic esters. Suitable fatty acids, or esters of fatty acids can come from the following oils: vegetable oil such as coconut oil, palm kernel oil, camelina oil, cuphea oil, soybean oil, palm oil, and canola oil. Other suitable oils are tung oil, meadowfoam oil, coriander oil, camelina oil, safflower oil, jatropha oil, cramby oil, high erucic rapeseed oil, algal oil, high oleoyl soybean oil (HOSBO), high oleoyl sunflower oil, castor oil, animal fats, and waste fats and oils as non-limiting examples.
Another source of both even and odd chain length, saturated and unsaturated fatty acids or esters for use in the making the amides of the invention can come from co-metathesis of short chain olefins with the various oils described above. U.S. Patent Application Publication No. 2006/0079704, incorporated herein by reference, discloses the metathesis of ethylene with unsaturated fats and oils (e.g., oleic sunflower oils, oleic rapeseed oils, and mono-alcohol esters thereof) in the presence of a ruthenium metathesis catalyst.
The α-alkene can include 1-propene, 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, and higher alkenes. PCT Patent Application No. WO 2008/046106, incorporated herein by reference, discloses the metathesis of terminal alkenes with fats and oils (e.g., soybean oil, sunflower oil, canola oil, safflower oil, cottonseed oil, castor oil, rapeseed oil, peanut oil, corn oil, olive oil, palm oil, sesame oil, grape seed oil) to form linear metathesis products using a ruthenium alkylidene catalyst. PCT Patent Application No. WO 2009/020667, incorporated herein by reference, discloses a method for improving catalyst efficiency by chemically treating a natural feedstock before introducing the metathesis catalyst to reduce the amount of catalyst poison. Similarly internal olefins can be used as above to generate a wider variety of even and odd chain length esters. The final unsaturated esters obtained from the above metathesis can be partially hydrogenated or fully hydrogenated to give mono-unsaturated esters or saturated esters for preparation of the sugar amides.
Furthermore, esters can also be branched as disclosed in WO 2011/088089A1 and WO 2012/009525A2.
In the above manner various mixed chain lengths, even and odd, branched or non-branched, saturated or unsaturated or mixtures of any of the above can be obtained for use in making the sugar amides. Other sources of even and odd chain length fatty acids or esters are disclosed in WO 2012/135760, US2011/0146142, EP2480680, US2010/0071259A1, and US2012/0070868. The above metathesis chemistry can also provide unique chain combinations that can be skewed, bimodal, peaked to allow the formulator to tune the type of properties they wish to obtain from use of the sugar amide compositions in various detergent applications. Examples in the literature where such combinations can potentially add additional performance vectors are disclosed in production of unique alkylbenzene sulfonate surfactants by Scheibel et al., US 2012/0214724A1, incorporated herein by reference. Examples of other developments in the surfactant industry are described in the Scheibel JSD Article, which is incorporated herein by reference. The potential for sugar amide combinations, however, is not limited to C10-C13 combinations as disclosed in the above cited reference. The sugar amide functional group allows for a much wider range of chain length options and unique chain combinations. The unique hydrophobic tail combinations described above can also allow for unique properties for non mixed sugar head groups such as Formula I or Formula II alone.
The mixture can also contain additional chemicals beyond those shown in Formulas I and II. In one embodiment, the mixture further comprises a third chemical, said third chemical having the chemical structure of Formula IV:
wherein R6 is selected from hydrogen, C1-C16 alkyl, C1-C3 hydroxy- or methoxy-alkyl; R7 is independently selected from C7-C23 alkyl, mono-alkenyl, di-alkenyl, or tri-alkenyl and mixtures thereof; and n3 is 2 to 4.
According to one embodiment, n3 is equal to 4. The chemical fragment in Formula IV not including the nitrogen atom, R6 or R7 has 6 carbon and 5 oxygen atoms. This chemical fragment can be derived from a six carbon sugar including but not limited to glucose, mannose or galactose and mixture thereof, provided it is not the same fragment derived from a sugar found in Formula I. For the avoidance of doubt, one embodiment of such a mixture comprises: a chemical of Formula I that contains a fragment derived from glucose, a chemical of Formula II that contains a fragment derived from xylose and a chemical of Formula IV that contains a fragment derived from mannose or galactose or mixtures of mannose and galactose.
According to a second embodiment, n3 is equal to 3. The chemical fragment in Formula IV not including the nitrogen atom, carbonyl, R6 or R7 has 5 carbon, and 4 oxygen atoms. This chemical fragment can be derived from a five carbon sugar including but not limited to xylose or arabinose and mixtures thereof provided it is not the same fragment derived from a sugar found in Formula I or Formula II. For the avoidance of doubt, one embodiment of such a mixture comprises: a chemical of Formula I that contains a fragment derived from glucose, a chemical of Formula II that contains a fragment derived from xylose and a chemical of Formula IV that contains a fragment derived from arabinose.
According to another embodiment, n1 is equal to 4, n2 is equal to 1 and n3 is 2 to 4. The chemical fragment in Formula I not including the nitrogen atom, R1 or R2 has 6 carbon and 5 oxygen atoms. This chemical fragment can be derived from a six carbon sugar including but not limited to glucose, mannose or galactose. The chemical fragment in Formula II not including the nitrogen atom, R3 or R4 has 3 carbon, and 2 oxygen atoms. This chemical fragment can be derived from a three carbon sugar or polyol including but not limited to glyceraldehyde or glycerol. The chemical fragment in Formula IV not including the nitrogen atom, carbonyl, R6 or R7 has 6 carbon and 5 oxygen atoms, 5 carbon and 4 oxygen atoms, or 4 carbon and 3 oxygen atoms. The chemical fragment in Formula IV can be derived from a six carbon sugar including but not limited to glucose, mannose or galactose and mixtures thereof, provided it is not the same fragment derived from a sugar found in Formula I. The chemical fragment in Formula IV can be derived from a five carbon sugar including but not limited to xylose and arabinose and mixtures thereof. The chemical fragment in Formula IV can be derived from a four carbon sugar. For the avoidance of doubt, one embodiment of such a mixture comprises: a chemical of Formula I that contains a fragment derived from glucose, a chemical of Formula II that contains a fragment derived from glycerol, and a chemical of Formula IV that contains a fragment derived from xylose, arabinose, mannose or galactose and mixtures thereof.
The processes to make sugars as well as the processes to make sugar amine and sugar amide structures have the potential to also make additional chemicals simultaneously. The additional chemicals may or may not be separated from the sugars, sugar amines, or sugar amides, and thus could be additional chemicals in the mixture. Additional chemicals that could be found in the mixture include sugar alcohols such as but not limited to glycerol, sorbitol, xylitol, dehydrated sugar alcohols such as but not limited to anhydrosorbitols, sorbitan and isosorbide; furan species, such as but not limited to furfural, furfural alcohol, hydroxymethylfurfural and dihydroxymethyl furan; tetrahydrofuran species such as but not limited to tetrahydrofurfuryl alcohol, and 2,5-bis(hydroxymethyl)tetrahydrofuran; an organic acid in either an acidic or neutralized form, such as but not limited to acetic acid, sodium acetate, ammonium acetate, or methyl ammonium acetate; monosaccharides; disaccharides; oligosaccharides; lignin residue including but not limited to phenolics; additional components derived from an enzymatic or microbial demixture; or a component with the chemical structure of either Formula I or Formula II with the proviso that an additional monosaccharide including but not limited to glucose, galactose, manose, xylose or arabinose, is attached to the primary alcohol in place of the hydrogen with a glycosidic bond.

A 160 ml Parr reactor was charged with Raney nickel (2.7 g, 15 wt % based on D-glucose, Grace 4200) and water (20 g). The reactor was sealed, purged three times with 300 PSI N2 followed by three times with 300 PSI H2. The reactor was then charged with 300 PSI Hz, at which point stirring was begun at 400 RPM, and heated to 100-110° C. for 1 hr. The reactor and contents were cooled to ˜10° C. with external cooling; stir rate was slowed to 100 RPM and vented to ˜100 PSI. Next D-glucose was added (45 g 40% aqueous solution, 100 mmoles, Amresco) followed by methyl amine (15.37 g 40% aqueous solution, 150 mmoles, Aldrich) via an HPLC pump at 5 ml/min while maintaining a temperature of around 10° C. Reactor was charged to 450 PSI H2, stir rate was increased to 400 RPM and allowed to warm to ambient temperature over 30 min. The reactor was then externally heated to 35° C. for 18 hrs, 50° C. for 1 hr, 75° C. for 1 hr and finally 100° C. for 1 hr during which time pressure was maintained at 300-500 PSI H2. The reactor was cooled to ambient temperature, vented and purged three times with 300 PSI N2. The contents were filtered and stripped of water under reduced pressure on a rotary-evaporator at 70° C. The resultant solid was dissolved in refluxing methanol (35 ml) and allowed to stand at ambient temperature 18 hrs to yield a white solid, which was filtered and dried to yield 12.2 g (62.5% yield); GC Analysis was conducted by derivatizing 2 mg analyte in pyridine (1.5 ml, Aldrich BioTech Grade) with 99:1 BSTFA+TMCS (0.5 ml, Supelco, Sylon BFT) at 70-80° C. for 30 min.

Krafft Point analysis was performed on a Phase Technology® NK60-KPA Analyzer that used a Diffusive Light Scattering (DLS) detection method. A 1 wt % solution was prepared in deionized water and 0.150 ml of this solution was added to the sample cell of the instrument at room temperature (20-25° C.). The following heating and cooling cycle was executed on the sample. Samples were warmed to 40° C. at a ramp rate of 5° C./min and held for 30 seconds. Next, Samples were cooled to −20° C. at a rate of −10° C./min and held for 60 seconds. Samples were then warmed to 0° C. at a rate of 5° C./min, held for 0 seconds, warmed to 30° C. at a rate of 2° C./min, held for 0 seconds and lastly warmed to 40° C. at a rate of 5° C./min.

At the beginning of temperature cycle, crystal count of the solution remained steady versus temperature defining a baseline crystal count value for the solution. When a sample froze upon cooling, the crystal count increased. During final warming cycle, when crystal count returned to original baseline, the temperature at that point was recorded as the Krafft point.

Additionally, in systems where the majority of the material is C12-NMG, small additions (5% or more) of C12-NMX can lower the Krafft point of the mixture below that of C12-NMG alone.

After partially stripping, propylene glycol (108 g) was added and stripping continued. 1284 g crude product paste resulted which was allowed to stand overnight in the flask. GC analysis using derivatization procedure in Example 1 showed conversion of 96.5% active materials. Citric acid (25 g), ethanol (216.4 g) and water (366 g) were used to prepare the final solutions (58.6% active product, 10% ethanol, 30% water. pH=7.29)
500 g solutions of title material blends (ratio given by weight) were prepared by weighing appropriate amount of C1214-NMG solution from Example 40 in a beaker. Next the appropriate amount of C1214-NMX solution from Example 41 was added. Solutions of 70:30 C1214-NMG:C1214-NMX and 30:70 C1214-NMG:C1214-NMX were prepared in this way.
The procedure of Example 33 was followed using the C1214-NMG, C1214-NMX and C1214-HMG:C1214-NMX solutions described in Example 40, 41 and 42 respectively, as noted below.
Mixtures of C1214-NMG and C1214-NMX solutions have potential to result in lower Krafft points than the either of the pure materials with a drastically lower point at 70% C1214-NMX and 30% C1214-NMG. When C1214-NMG is mixed with materials based on a shorter starting sugar or polyol group such as C1214-NMX, the physical thermal properties are improved beyond either C1214-NMG or the C1214-NMX. This improvement is shown with a drop in temperature of the Krafft point to a value of 5° C., far below either 100% C1214-NMG at 34° C. or 100% C1214-NMX at 16° C.
N-methylglucamine (25 g, 128.6 mmol, Aldrich), Hexanal (15.5 g, 155 mmol, Aldrich), 5% Pd on Carbon (1 gram, Aldrich) and 40 mL of methanol were added to a 160 mL Parr Reactor. The reactor was sealed, purged three times with 300 PSI N2 followed by three times with 300 PSI H2. The reactor was then charged with 500 PSI Hz, at which point stirring was begun at 400 RPM, and was allowed to remain at room temperature for 1 hr. The reactor was then externally heated to 50° C. for 18 hrs, then 75° C. for 1 hr, during which time pressure was maintained at 300-500 PSI H2. The reactor was cooled to ambient temperature, vented and purged three times with 300 PSI N2. The contents were filtered to remove the catalyst and the methanol removed to yield a white precipitant. Precipitant was filtered and washed with cold methanol to yield white powder, (23 g, 98% desired products using GC using derivatization described in Example 1).
Followed procedure of Example 44 using n-methylxylamine (30.4 g of 65 wt % solution in methanol, 120 mmol, synthesis described in Example 2) in place of n-methylglucamine and less hexanal (14.4 g, 144 mmol, Aldrich). (25.75 g, 95% desired products using GC using derivatization described in Example 1).
0.50 g samples of title material blends (ratio given by weight) were prepared by weighing appropriate amount of individual materials and combining in glass vial with methanol (3 grams). The glass vials were stirred with magnetic stir bars and heated to 35° C. for 1 hour. Solvent was allowed to evaporate under hood air flow and then aged 18 days at ambient temperature prior to thermal property analysis.
The procedure of Example 30 was followed using the mixed NMHG:NMHX samples described in Example 46.
The physical thermal properties of NMHG and NMHX along with mixtures of these two components as measured by DSC can be found in the data presented above. As with other examples, like Example 29, when NMHG is mixed with materials based on a shorter starting sugar or polyol group such as NMHX, the physical thermal properties are improved beyond either NMHG or NMHX. This improvement is shown with a drop in temperature of the initial phase transition (T Intercept in Table 11) to a value below either individual component for the NMHG:NMHX system over a range of around 50-90% NMHX.
The physical thermal properties of pure sugar amide and amine systems can be found in the examples above. When materials based on glucose amides and amines such as C12-NMG are mixed with materials based on a shorter starting sugar or polyol group such as C12-NMX or C12-NMGly, the physical thermal properties are improved beyond either of the glucose derived amide/amine or the other sugar amide/amine with a shorter starting sugar or polyol group. This improvement in thermal properties has been measured by multiple techniques and been demonstrated for multiple thermal transitions including initial phase transition observed in DSC, initial visual melting points and Krafft Points. This improvement has further been demonstrated for multiple fatty chain lengths including both saturated and unsaturated examples. This improvement has been further demonstrated for mixtures of fatty chain lengths such as a mixed distribution from Coconut Oil, and has been demonstrated on mixed chains that are in solution, namely C1214 from CE-1270 (70% C12, 30% C14) at about 58% active in water, ethanol and propylene glycol. This improvement has lastly been shown for amines such as NMHG and NMHX.
