DETAILED DESCRIPTION [0056] Whenever the term “at least,” “greater than,” or “greater than or equal to” precedes the first numerical value in a series of two or more numerical values, the term “at least,” “greater than” or “greater than or equal to” applies to each of the numerical values in that series of numerical values. For example, greater than or equal to 1, 2, or 3 is equivalent to greater than or equal to 1, greater than or equal to 2, or greater than or equal to 3. [0057] Whenever the term “no more than,” “less than,” or “less than or equal to” precedes the first numerical value in a series of two or more numerical values, the term “no more than,” “less than,” or “less than or equal to” applies to each of the numerical values in that series of numerical values. For example, less than or equal to 3, 2, or 1 is equivalent to less than or equal to 3, less than or equal to 2, or less than or equal to 1. [0058] Certain inventive embodiments herein contemplate numerical ranges. When ranges are present, the ranges include the range endpoints. Additionally, every sub range and value within the range is present as if explicitly written out. The term “about” or “approximately” may mean within an acceptable error range for the particular value, which depends in part on how the value is measured or determined, e.g., the limitations of the measurement system. For example, “about” may mean within 1 or more than 1 standard deviation, per the practice in the art. Alternatively, “about” may mean a range of up to 20%, up to 10%, up to 5%, or up to 1% of a given value. Where particular values are described in the application and claims, unless otherwise stated the term “about” meaning within an acceptable error range for the particular value may be assumed. [0059] The abbreviations used herein have their conventional meaning within the chemical and biological arts, unless otherwise specified. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts. [0060] Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., -CH ₂ O- is equivalent to -OCH ₂ -.

[0099] Methods of producing a biomass derived surface-active compositions. [0100] Described herein are methods of producing biomass derived surface-active compositions [0101] A method of producing a biomass derived surface-active composition may comprise: (a) providing a lignocellulosic biomass, (b) isolating a saccharide mixture from the lignocellulosic biomass, the saccharide mixture comprising oligosaccharides; and (c) reacting the saccharide mixture with one or more fatty chain compounds in one of a plurality of steps. [0102] The lignocellulosic biomass may comprise grain, grain chaff, oat, oat hulls, oat husks, bean pods, seed coats, seed materials, seaweeds, corn cob, corn stover, corn leaves, corn stalks, straw, wheat, wheat straw, wheat bran, wheat middlings, rice straw, soy stalk, bagasse, sugar cane, sugar beet, sugar cane bagasse, miscanthus, sorghum residue, switchgrass, bamboo, monocotyledonous tissue, dicotyledonous tissue, fern tissue, water hyacinth, leaf tissue, roots, vegetative matter, vegetable material, vegetable waste, hardwood, hardwood stem, hardwood chips, hardwood pulp, softwood, softwood stem, softwood chips, softwood pulp, paper, paper pulp, cardboard, wood-based feedstocks, grass, nut shell, poplar, willow, sweet potato, cotton, hemp, jute, flax, ramie, sisal, or cocoa. [0103] The saccharide mixture may be obtained from the lignocellulosic biomass by hydrolysis, including by partial hydrolysis. [0104] Hydrolyzing the lignocellulosic biomass may comprise using enzymes from a fungus.

The aqueous phase was extracted with additional DCM. The combined organic phase washed with saturated aqueous NH ₄ Cl solution, then the aqueous phase extracted with additional DCM. The combined organic phases were dried over anhydrous magnesium sulfate, filtered, then concentrated under reduced pressure to give a yellow oil. The oil was purified by FCC eluting with MeOH (2-15%) in DCM (120 g normal phase silica cartridge with wet loading). Fractions containing the product were combined and evaporated to dryness to give the desired product (4.1 g, 49%) as a yellow gum. LC-MS (Method A), Rt = 1.69 min, [M+H] ⁺ = 332.2.

LC-MS (Method G) Rt = 1.99 min, [M-H]- = 550.4. [0314] When the feedstock is 100% COS, the surface-activity of the products is acceptable, but surprisingly, reaction times are very long, and the yields are low. It was additionally unexpected that water was required as part of the solvent medium in step (i) to achieve an appreciable rate of reaction, despite it being known that water may degrade the intermediate. When the feedstock is 100% monosaccharides, the surface-activity of the products is surprisingly improved versus when the feedstock is 100% COS, across a range of different carbon chain-lengths, but the products are generally viscous oils that lack particular processing options. When the feedstock is 100% XOS, the reaction is more effective due to fewer side-products being detected and the products are solids. However, when the feedstock is a mixture of XOS and COS, the products retain their solidity and additionally perform unexpectedly superior in application tests than other aforementioned feedstocks.

The peak area of signals corresponding to monosaccharide products was 35.7% of the total area for all selected compounds (and 64.3% of the peak area was from signals corresponding to compounds wherein the saccharide component had a DP of 2-10). No further monosaccharide products to those stated in FIG. 19B were detected. [0354] When the feedstock is 100% COS, the surface-activity of the products is acceptable, but reaction times are unexpectedly very long, and the yields are low. When the feedstock is 100% monosaccharides, the surface-activity of the products is acceptable, but they are generally viscous oils that lack particular processing op When the feedstock is 100% XOS, the reaction is unexpectedly more effective due to fewer side-products being detected and the products are solids. However, when the feedstock is a mixture of XOS and COS (excluding monosaccharides), the products surprisingly and additionally perform superior in application tests than other aforementioned feedstocks. When the feedstock is a mixture of XOS and COS, which includes monosaccharides, the overall product performed similarly well in application testing to if the feedstock mixture of COS and XOS did not include monosaccharides, but has the additional, surprising advantage that the amine intermediate mixture (e.g., N-dodecyl-N- oligosylamine) is readily separated from the reaction mixture by filtration.

The use of the trans-esterification method of section L. allowed products with a higher DP in the sugar component to be detected on some occasions than the direct method of section K. M.

To this gel base was added one part (by mass) of 52 wt% aqueous solution of Example 5 composition (N-dodecyl-N-acetylxylo-oligosylamine), for every nine parts of gel base. The resulting mixture was stirred under vigorous magnetic stirring until forming a beige-brown gel phase. N.

[0392] a) Example 54 – gel product using guar gum base and example 34 composition [0393] The gel base (90 wt%) was mixed with pre-dissolved Example 34 composition (N- dodecyl, N-acetyl oligosylamine, 2.5 wt%) in water (7.5 wt%) to form a yellow gel that was stable for at least 1 week.

A photograph of this product is depicted in FIG. 27A. [0401] b) Example 58 – attempt at preparing a gel product using xanthan gum base and larger amount of Example 5 composition [0402] The gel base (90 wt%) was mixed with pre-mixed Example 5 composition (N-dodecyl- N-acetylxylo-oligosylamine, 5.2 wt%) and water (4.8 wt%). The mixture failed to form a stable gel. [0403] c) Example 59 – gel product using xanthan gum base and lesser amount of Example 5 composition [0404] The gel base (90 wt%) was mixed with Example 5 composition (N-dodecyl-N- acetylxylo-oligosylamine, 2.5 wt%) in water (7.5 wt%) to form a cream gel that was stable for at least 1 week.

[0407] a) Example 60 – gel product using carbomer base and example 34 composition [0408] The gel base (90 wt%) was mixed with pre-dissolved Example 34 composition (N- dodecyl, N-acetyl oligosylamine, 2.5 wt%) in water (7.5 wt%) to form an off-white gel that was stable for at least 1 week. [0409] b) Example 61 – attempted preparation of a gel product using carbomer base and larger amount of Example 5 composition [0410] The gel base (90 wt%) was mixed with pre-dissolved Example 5 composition (N- dodecyl-N-acetylxylo-oligosylamine, 5.2 wt%) and water (4.8 wt%). The mixture failed to form a stable gel. [0411] c) Example 62 – gel product using carbomer base and lesser amount of Example 5 composition [0412] The gel base (90 wt%) was mixed with Example 5 composition (N-dodecyl-N- acetylxylo-oligosylamine, 2.5 wt%) in water (7.5 wt%) to form a cream gel that was stable for at least 1 week. Q. Preparation of water-in-oil emulsions from the new surface-active ingredients [0413] a) Example 63 – Water-in-oil emulsion using Example 5 composition [0414] A viscous, water-in-oil emulsion using an inventive surface-active composition as the emulsifier was prepared by combining water (27 wt%) with sunflower oil (70 wt%), and Example 5 composition (N-dodecyl-N-acetylxylo-oligosylamine, 3 wt%) to form a cream gel. A photograph of this gel product is depicted in FIG. 27B. [0415] b) Example 64 – Alternative water-in-oil emulsion using example 34 composition [0416] A viscous, water-in-oil emulsion using an inventive surface-active composition as the emulsifier was prepared by combining water (27 wt%) with sunflower oil (70 wt%), and Example 34 composition (N-dodecyl, N-acetyl oligosylamine, 3 wt%) to form a white gel. A photograph of this gel product is depicted in FIG. 27C. R. Application tests of the described inventive surface-active compositions [0417] a) Example 65 – Emulsion Stability Application Testing [0418] Step (i) Water in Oil emulsions [0419] 0.5 mL deionized water containing 2 wt% of the stated inventive or comparative compound was added to 1.5 mL commercial, food-grade sunflower oil, in a sample vial. The vials were each agitated with a IKA Vortex mixture for 30 seconds. The vials were left to stand and inspected visually for emulsion quality after 5 minutes, 1 hour, 4 hours and finally 24 h (FIG. 14 and FIG. 15). These test results show that the ability of the new inventions as emulsifiers is competitive with or even superior to commercial alternatives. The results also show an unexpected increase in emulsifying performance for the inventive compositions comprising oligosaccharide mixture-derived surface-active agents (such as example 4-6 compositions) compared with those derived from a single monomeric sugar (xylose) alone (such as example 12 and 13 compositions). In particular, Example 6 composition was surprisingly found to form an exceptionally stable water-in-oil emulsion that had not separated after 5 months. The results are shown in table 1. Table 1: results of the water-in-oil emulsion tests of Example 65.

Mixtures of water, vegetable oil and inventive surface-active composition were prepared as per table below, by adding groundnut oil, water, and surface-active composition in the desired mass ratio. The mixtures were heated at 60 °C in a homogenizer (stirring for 10 minutes at 800 rpm, then further homogenized at this speed and ambient temperature for 5 min). The visual appearance of each mixture was acknowledged. The mixtures were then treated by centrifugation at 1500 rpm for 5 min and the visual appearance was again acknowledged. The results show that the inventive surface-active compositions tested are good water-in-oil emulsifiers and surprisingly that the example 34 composition, which consists of mixed mono and oligosaccharides, could form more stable emulsions than other formulations. The results are shown in table 2. Table 2: Emulsification tests of different inventive surface-active compositions of Example 66 Surface-Active Composition Water-oil ratio Visual interpretation of results.

Example 5 composition (N- 1:1 Emulsion formed initially, though dodecyl-N-acetylxylo- separated following oligosylamine (3.0 wt%) centrifugation Example 34 composition (N- 1:1 Emulsion formed initially, though dodecyl, N-acetyl separated following oligosylamine (3.0 wt%) centrifugation Example 5 composition (N- 1:2 Emulsion formed initially, though dodecyl-N-acetylxylo- separated following oligosylamine (3.0 wt%) centrifugation Example 5 composition (N- 2:1 Emulsion formed initially, though dodecyl-N-acetylxylo- separated following oligosylamine (3.0 wt%) centrifugation Example 5 composition (N- 1:2.5 Stable emulsion observed, dodecyl-N-acetylxylo- including after centrifugation oligosylamine (3.0 wt%) Example 11 composition (N- 1:2.5 Emulsion failed to form. decyl N-acetyl Complete phase-separation xylosylamine, 3.0 wt%) following centrifugation [0422] c) Example 67 - Stability of emulsions formed by homogenizer treatment [0423] 60 mg of either inventive example surface-active composition, or comparative example substance was dissolved in deionized water (0 L) and sunflower oil (2.25 mL) was added. The resulting mixture was treated with a mechanical homogenizer for 5 min. The visual appearances of the treated mixtures were interpreted by inspection. The mixtures were then treated by centrifugation at 2000 rpm for 2 min. The visual appearances were again interpreted by inspection and compared to the previous appearances before centrifugation. If the mixture had formed a distinct aqueous phase, the volume of the emulsified oil phase was measured. The mixtures were then further treated by centrifugation at 2000 rpm for 2 min. The visual appearances were again interpreted by inspection and compared to the previous appearances. The mixtures were then further treated by centrifugation at 2000 rpm for 2 min. The visual appearances were again interpreted by inspection and compared to the previous appearances before centrifugation. All results were photographed and are shown in FIG. 26. The interpretation of the results is that all inventive surface-active compositions were effective water-in-oil emulsifiers. Some variation was observed: generally, the surface-active compositions generated from feedstocks high in monosaccharide or cellobiose content, appeared less stable and broke more easily than those generated from feedstocks high in xylo- oligosaccharides, though this is based on inspection. [0424] d) Example 68 - Zein Solubilization test [0425] Zein is a water-insoluble corn protein, structurally similar to keratin. The ability of a surfactant to solubilize zein is related to irritation potential. The more zein solubilized, the more irritating the product is deemed to be, according to this test. Zein (25 mg) was added to 1 wt% active surfactant solution (1 mL) and mixed under centrifugation at 30 rpm for 30 min. The solutions were centrifuged, and the protein concentration in the supernatant determined by BCA assay. Each surfactant was tested in triplicate. Protein content was determined from a bovine serum albumin (BSA) standard curve. The test results (FIG. 18 and Table 3) show the new inventions are poor solubilizers for zein and hence can be described as less irritating, when compared to existing Comparative surfactants. Table 3: Results of the zein solubilization test of Example 68 for comparative and inventive compositions.

Air (40 cm ³ ) was bubbled through the surface-active composition solution at a rate of 17 cm ³ /min via a syringe pump and the foam height upon complete addition of air recorded. The foam height was also recorded again 5 min after complete addition of air, 10 min after complete addition of air, 15 min after complete addition of air, 30 min after complete addition of air, 1 hour after complete addition of air and finally 2 hours after complete addition of air. Graphical results and images of the different foams generated are shown in FIG. 12 and table 4.

The results also show that surface-active compositions of oligosaccharides excluding monosaccharides could form more stable foams than mixtures of oligosaccharides that included monosaccharides, however this is apparent only after between 15- 30 minutes and few applications would require a surface-active composition to remain foaming for such a length of time. [0429] g) Example 70 – Flash Foam generation test [0430] 20 mg of each surface-active composition for testing was dissolved in deionized water (4 mL) to give a 10 wt% solution, 2 mL was added to a 15 mL FALCON tube. Each falcon tube was secured in a holder before being vigorously shook for 30 seconds. The initial foam height and structure was noted. The foam height was then noted at 5 min, 10 min, 15 min, 30 min, 45 min, 1 hr and 2 hr after the initial measurement. The experiment was repeated in duplicate. Averaged results are depicted in table 5 and FIG. 11.

See FIGS. 9-10, 13A- 13B. FIG. 9 illustrates foaming tests conducted for the stated inventive surface-active agents (0.5 % wt) in water and a solution of 10% ethanol in water compared with the xylooligosaccharides mixture, decylamine and dodecyl glucoside at time zero minutes (immediately after agitation). FIG. 10 depicts the results of the same experiments after 0 minutes (immediately after agitation) but also after 5 min and 30 min. FIG. 13B further depicts specifically the illustrates foaming tests conducted for examples 5, 6 and 7 in water (0.5% wt) at time zero minute, five minutes, and thirty minutes, with FIG. 13A showing an image of the foam appearance after 10 minutes. [0432] The surface-active compositions all demonstrated flash-foam generation upon agitation of their aqueous solutions. For XOS-derived surface-active compositions with shorter alkyl chains (example compositions 4 and 5), the foam height and stability were notably lower in ethanol/water (1:9 v/v) compared with for pure water. Surprisingly, it was found that the foam heights for XOS-derived surface-active compositions with longer chains (example compositions 6 and 7) were higher in ethanol/water (1:9 v/v) compared with for pure water, and that the presence of ethanol did not significantly destabilize the foam (FIG. 10). Generally, compositions containing higher proportions of XOS versus COS reached greater foam heights than compositions with higher COS than XOS proportions, though this did not translate to significant differences in foam lifetime. [0433] h) Example 71 – Lipophilic substances solubilization test – Lemongrass Oil [0434] Determination of the solubilization improvement of an example lipophilic oil (lemongrass essential oil) was determined by stepwise addition (2.5 µL) of neat lemongrass essential oil to 2 mL of 5 wt% surface-active compound aqueous solution. After each addition, the sample was agitated with a vortex mixture for 60 s and left to stand for 5 min. If no heterogenous phase was observed visually, the oil was said to be fully soluble. If a heterogenous, immiscible biphasic or emulsion was visible, then the saturation limit for that surface-active component was said to have been exceeded. Each surface-active composition was tested in duplicate. The results (table 6) show th t the new inventions are surprisingly effective solubilizers for lemongrass essential oil, and likely essential oils and lipophilic chemical compounds in general. Interestingly, example 11 composition was a notably good solubilizer for lemongrass oil. Table 6: Lemongrass oil solubilization test results Substance Inventive or Maximum volume of Comparative lemongrass oil solubilized (µL) Sodium Dodecyl Sulfate Comparative 2.5 Decyl glucoside Comparative 2.5 Emulsifan Comparative 3.75 Water Comparative 0.0 Example 14 composition Inventive 5.0 (N-octyl-N- acetylxylosylamine) Example 11 composition Inventive 8.75 (N-decyl-N- acetylxylosylamine) Example 13 composition Inventive 5.0 (N-dodecyl-N- acetylxylosylamine) [0435] i) Example 72 – Lipophilic substances solubilization test- Preservative P12 [0436] Determination of the solubilization improvement of an example lipophilic oil (preservative 12 oil) was determined by stepwise addition (10 µL) of neat preservative 12 oil (supplier) to 2 mL of 5 wt% surface-active compound aqueous solution. After each addition, the sample was agitated with a vortex mixture for 60 s and left to stand for 5 min. If no heterogenous phase was observed visually, the oil was said to be fully soluble. If a heterogenous phase or emulsion was visible, then the saturation limit for that surface-active component was said to have been exceeded. Each surface-active composition was tested in duplicate. The results (table 7) show that the new inventive compositions are surprisingly effective solubilizers for preservative P12. They also show that surface-active compositions containing COS and XOS product mixtures are more effective solubilizes of Preservative P12 if the COS content is 25% or lower, which was unexpected.

A test compound 10 mg/mL stock solution was prepared by dissolving Example 11 composition (N-decyl-N-acetylxylosylamine) (inventive surface-active composition) in DMSO. Buffer solutions, comprised of simple, commercially-available acidic or basic substances in deionized water were prepared at pH 1, pH 3, pH 4, pH 5, pH 6, pH 7, pH 9, pH 11 and pH 13. 950 µL of each buffer solution were dispensed into a sample vial and to each was added 50 µL of the test compound stock solution (hence preparing solutions with initial concentration of 0.5 mg/mL. The solution was immediately placed in an insulated autosampler maintained at 25 ºC and injected without delay into the UPLC-MS (Waters Acquity-TQD). Additional injections were performed at appropriate time points. Concentrations of the test compound were determined from the MS response. Results, shown in table 8, were categorized by the % of the original concentration that had been lost to degradation after 12 hours and again after 1 week of incubation. The result was said to be ‘full stability’ if the change in concentration detected was within the expected error of the starting concentration. Table 8: The results of the hydrolytic stability study of Example 11 composition, from Example 73. Buffer Stability During 12-hour Stability During 1-week pH Assay (daily monitoring) 1 Minor (< 1%) degradation Significant degradation (< 50%) 3 Extremely Minor (< 0.1%) Extremely Minor (< 0.1%) degradation degradation 4 Full stability Full stability 5 Full stability Full stability 6 Full stability Full stability 7 Full stability Full stability 9 Full stability Full stability 11 Extremely Minor (< 0.1%) Extremely Minor (< 0.1%) degradation degradation 13 Extremely Minor (< 0.1%) Partial degradation (< 10%) degradation [0439] k) Example 74 - Relative Viscosity [0440] To Solutions of 10 wt% sodium dodecyl sulfate (10 mL) was added 0.3 g of NaCl and 0.655 mL of 30 wt% testing surface-active composition solution. The mixtures were then stirred for 15 min until homogeneous and maintained at 27 ^o C, with stirring, until the time of testing. 4.5 mL of each testing mixture was added to separate 5 mL stripettes (cut at the 5 mL line). The time taken for precisely 3 mL of testing mixture to pass out of the stripette by gravity was recorded. The test was repeated in triplicate. Averaged results are depicted in FIG. 20 and table 9. It was unexpected that example 11 composition recorded such high viscosity over example 14 composition, which differs by a slightly smaller alkyl chain (octyl instead of decyl). Table 9: The results for relative viscosity tests of Example 74. Testing surface- Inventive or Average time active composition Comparative (s) Example 14 composition (N- Inventive 10.0 octyl-N- acetylxylosylamine) Example 11 composition (N- Inventive 270.3 decyl-N- acetylxylosylamine) D _{odecyl glucoside} ^{Comparative 4.0} Lauryl glucoside Comparative 1.9 C _{oco glucoside} ^{Comparative 20.7} Cocamidopropyl b _etaine ^{Comparative 524.0} No testing surface- a _{ctive composition} ^{Comparative 1.5} [0441] l) Example 75 - Horizontal Pseudo-two-dimensional foam stability [0442] For each sample, 4.0 x 1.0 x 3.5 cm strips of 1 mm thick double-sided tape were cut and stuck to the inside lid of a petri dish in an arrangement shown in FIG. 24 as to create a 3x3 cm square cell. [0443] For this test the following inventive surface-active compositions were trialed: Example 11 composition, Example 7 composition, Example 6 composition, Example 4 composition, Example 5 composition, Example 27 composition, Example 26 composition, Example 25 composition, Example 23 composition. As a comparative example, decyl glucoside was also trialed. 10 mg of example surface-active composition was dissolved in 2 mL of deionized water in a 15 mL FALCON tube and was then shaken vigorously for 30 seconds, to generate a foam in the head-space above the solutions. FIG. 24 depicts a diagram of top view and side view to show how an application test of the foaming characteristics of some surface-active compositions was performed. Further, FIG. 25 depicts photographs of isolated foaming phases generated from agitated aqueous solutions of surface-active, immediately after isolation and then 5 h later using a setup depicted in FIG. 24. A 400 µL sample was pipetted from the midpoint of the foaming head-space above the solutions and placed onto the prepared petri-dish lid, within the boundaries of the double-sided tape cell (FIG. 24). The base of the petri-dish was then placed inside the up- turned lid of the petri-dish and stuck to the double-sided tape. The foam was then photographed initially and again after 5 hr. The photographs obtained are depicted in FIG. 25. The results demonstrate that the inventive surface-active compositions are capable of forming foams that are stable for more than 5 h, albeit at reducing bubble-density over time. [0444] m) Example 76 – verification of ability of inventive composition to remove common stains from objects [0445] (i) Removing fingerprint stains from glass surface [0446] To a glass mirror that was visibly contaminated with fingerprint stains, as depicted in FIG. 23A, was sprayed 0.5 mL of Example 51 formulated solution product. The treated mirror surface was then wiped across with absorbent laboratory tissue three times. The presence of the fingerprint stains was no longer apparent by visual inspection, as depicted in FIG. 23D. [0447] (ii) Removing grease stain from plastic surface [0448] To a plastic sample-plate box lid that was visibly contaminated with a greasy residue, as depicted in FIG. 23B, was sprayed 0.5 mL of example 51 formulated solution product. The treated plastic surface was then wiped across with absorbent laboratory tissue three times. The presence of the greasy residue was no longer apparent by visual inspection, as depicted in FIG. 23E. [0449] (iii) Removing a cosmetic product stain from veneer benchtop surface [0450] To a synthetic veneer-surfaced benchtop that was visibly contaminated with an oil-based cosmetic product containing a colorant, as depicted in FIG. 23C, was sprayed 0.5 mL of example 51 formulated solution product. The benchtop surface was then wiped across with absorbent laboratory tissue three times. The presence of the cosmetic product stain was no longer apparent by visual inspection, as depicted in FIG. 23F. [0451] n) Example 77 – Salt-induced thickening of solutions containing surface-active compositions [0452] To an aqueous solution of sodium dodecyl sulfate (5 mL, 10 wt%) was added sodium chloride (3 wt%) and selected inventive or comparative surface-active composition (2 wt%). The formed liquid was placed in a jar and rotated 90° and photographed, to obtain a visual interpretation of the thickness. The photograph is depicted in FIG. 17. The surface-active composition included in the test were example 5 composition (inventive, FIG 17). The result showed that the formulations containing inventive surface-active compositions displayed the desired thickened effect expected of surface-active compositions. [0453] o) Example 78 - Critical Micellular Concentration Determination [0454] Stock solutions were prepared of known weight concentration (range spanning 0.005 wt% - 5.000 wt%) of inventive surface-active compositions (by solution of the appropriate weight of example composition in deionized water). For reference, the surface tension of deionized water in the absence of a surface-active composition is 73 mN. The surface tension at the different concentrations was measured and from this data, the CMC was calculated as the concentration where further increases in concentration did not lead to a greater reduction in surface tension. The surface tensions of the solutions at the concentration of the CMC were also noted. Results are shown in table 10 and graphical results are depicted in FIG. 22. Table 10: Results of the critical micellular concentration determination experiments of Example 78 Substance Inventive or CMC (wt %) Solution Surface Comparative tension at CMC (mN) Example 5 composition (N-dodecyl-N- Inventive 0.03 39 acetylxylo- oligosylamine) Example 27 composition (N- dodecyl-N- Inventive 0.02 41 acetyloligosylamine 75:25 (XOS:CB)-C12) Example 26 composition (N- dodecyl-N- Inventive 0.02 43 acetyloligosylamine 50:50 (XOS:CB)-C12) Example 25 composition (N- dodecyl-N- Inventive 0.03 44 acetyloligosylamine 25:75 (XOS:CB)-C12) Example 23 composition (N- dodecyl-N- Inventive 0.03 45 acetylcellobiosylamine) Example 11 composition (N-decyl- Inventive 0.04 36 N-acetylxylosylamine) Example 17 composition (N- tetradecyl N-acetyl Inventive < 0.005% 46 oligosylamine (XOS/COS = 3:1)) [0455] The results show that all the inventive surface-active concentrations greatly reduce the surface tension and reach their CMC at low wt % concentrations. Example 17 composition was found to have an especially low wt% (the value was found to be below 0.005 wt%, but cannot be estimated more precisely). CMC values or the surface tension at the CMC did not correlate significantly with chemical structures or identities of molecules, but the test confirms decisively the surface-active nature of the inventive compositions. Similarly, the surface tensions of the solutions of inventive example were much lower than water alone and competitive with commercially-used surface-active compositions (generally 30-50 mN).
