Description

2410741Compositions of N-acylated proline or derivatives thereof and their useThis invention deals with specific compositions of N-acylated proline or derivatives thereof (in this present invention abbreviated as "inventive composition” or "compounds of the invention” whenever the inventive compositions are meant) comprising at least one N-acylated proline or derivative thereof and at least one N-acylated glutamate or derivative thereof, their uses and compositions including the inventive compositions, particularly as laundry detergent compositions.Anionic surfactants, particularly the sulphonates such as linear alkylbenzene sulphonate (LAS) and the sulphates such as alkyl ether sulfates (AES, in particular SLS (sodium laureth sulfate)) and primary alkyl sulphate (PAS), are the key ingredients of modern laundry detergents, providing excellent detergency performance on a wide range of soils and stains.However, detergent formulators are continuously faced with the task to improve the environmental "footprint” of any product, be it in terms of its origin like being from natural or renewable resources, or compared to previous products, its production in terms of production efficiency and thus reduced usage of energy, its efficiency in usage such as reduced amounts for the same performance or higher performance at the same amount levels used, its persistence in the natural environment after its usage, especially its biodegradation, since recycling is technically very challenging and therewith economically not attractive.Hence, due to the climate change, one of the most important targets of the detergent and cleaner (D&C) industry today is to significantly lower the CO2 emission per wash. Surfactants, such as LAS are based on fossil carbon sources and therefore their production is incompatible with the environmental-friendly aims of the D&C industry. AES might comprise 1 ,4-dioxane as by-product and therefore alternatives free of 1 ,4-dioxane are desired.Additionally, the industry is looking for surfactants that provide a high degree of biodegradability after their use and release into the environment.To overcome these problems, alternative surfactants that provide significant wash performance and which are (or can potentially be) based on non-fossil carbon sources and provide a high degree of biodegradability are of interest for the D&C industry.One such alternative group of surfactants are amino acid-based surfactants, such as N-acylated lysine and proline.In the following, a summary of the current knowledge and most relevant publications in the field of the present invention, the use of N-acylated proline and similar compounds is given.WC2018206878 A1 and WC2009118493 A2 describe specific synthesis methods for N-acylated proline. However, these patents documents provide no information about functional data of the synthesized compounds, let alone any data with respect to cleaning and wash performance. Therefore, these documents provide no hint to combine N- acylated proline with N-acylated glutamate to increase its surfactant and wash performance.2410742CN104219964 B and US10, 711 ,230 B2 describe the use of N-acylated proline in food compositions. In CN104219964 B the N-acylated proline is described as a food fragrance compound, whereas in US10, 711 ,230 B2 it is mentioned that N-acylated proline can be used as a food flavoring compound. As before, none of these documents provides no hints to combine N-acylated proline with N-acylated glutamate to increase its surfactant and wash performance.EP3621959 A1 describes a composition comprising acylated amino acid based on proline, acylated dipeptide (based on the proline), fatty acid and optionally dipeptide based on proline. In addition, a process for the manufacturing and cosmetic compositions are revealed. Also here, the document provides no hints to combine N- acylated proline with N-acylated glutamate to increase its surfactant and wash performance.Sreenu et al. (Sreenu, M. et al. (2015), j. Oleo Sci. 64, (11), pages 1175-1184) describe the surface-active properties of N-acyl prolines. When the N-acyl prolines are compared to sodium laureth sulfate (SLS) they show inferior performance in wetting time, surface tension and foam height. These disadvantages can be overcome by combining the N-acylated proline with N-acylated glutamate as experimentally demonstrated by the present inventors.The cleaning and personal care industry is well-aware of the potential of acylated amino acids as surfactants. One example of such amino acid-based surfactants is N-acylated lysine as described by Shi et al. (Shi, T.T. RSC Adv. 2019 Mar 1 ; 9(13): 7587-7593.). However, a combination of N-cocoyllysine sodium salts shows significantly weaker overall wash performance than combinations of N-acylated prolines.In contrast to above-described documents, the present invention is not directed to a single N-acylated proline or N- acylated lysine but to a combination of N-acylated proline and N-acylated glutamate.Thus, the present inventors surprisingly found that combining at least one N-acylated proline and at least one N- acylated glutamate, preferably in a ratio wherein the N-acylated proline possesses the weight majority, will provide synergistic effects in wash properties over the ones observed for comparable single compounds. This results in a composition of surfactants that has significant wash performance and can potentially be based on non-fossil carbon sources and can potentially provide a significant degree of biodegradability.Therefore, the object of the present invention is to provide novel compositions comprising(1) at least one compound according to Formula (1)whereinR1 is an aliphatic, saturated or unsaturated, linear or branched moiety comprising 7 to 17 carbon atoms, and241074 the dotted lines indicate ording to Formula (2)whereinM+is selected from the group consisting of H+, Na+, K+, NH4+, protonated amine and protonated amino alcohol, or ii) bonds to the remaining parts of the compound according to Formula (1), wherein at least one remaining part comprises at least one five-membered ring and a directly bound moiety according to Formula (3); and(2) at least one compound according to Formula (3)wherein n is an integer between 1 and 5;R2 is an aliphatic, saturated or unsaturated, linear or branched moiety comprising 7 to 17 carbon atoms; andM+is as defined above.In another aspect, the invention is directed to a cleaning method and uses of the inventive composition in cleaning formulations and compositions.Thus, subjects of the present invention are the following Embodiments 1 to 15 as defined and further explained with further embodiments hereinafter and further exemplified in the experimental section.Embodiment 1A composition comprising(1) at least one compound according to Formula (1)241074whereinR1 is an aliphatic, saturated or unsaturated, linear or branched moiety comprising 7 to 17 carbon atoms, and the dotted lines indicateI) a moiety according to Formula (2)whereinM+is selected from the group consisting of H+, Na+, K+, NH4+, protonated amine and protonated amino alcohol, or ii) bonds to the remaining parts of the compound according to Formula (1), wherein at least one remaining part comprises at least one five-membered ring and a directly bound moiety according to Formula (3); and(2) at least one compound according to Formula (3)wherein n is an integer between 1 and 5;R2 is an aliphatic, saturated or unsaturated, linear or branched moiety comprising 7 to 17 carbon atoms; andM+is as defined above.The inventive composition is directed to I) N-acylated proline or derivatives thereof and ii) N-acylated glutamate or derivatives thereof. Basically, these compounds comprise at least one alkyl part that is attached to the nitrogen atom of the amino acids.Proline, the starting compound for N-acylated proline, can be derived by chemical synthesis or by fermentation. If derived by chemical synthesis, the synthesis of proline is based on using glutamic acid as a raw material,2410745 subsequent esterification with absolute ethanol under the catalysis of sulfuric acid, and then triethanolamine is added to free the aminosulfate to obtain glutamic acid-6-ethy I ester. The glutamic acid-5-ethyl ester is then reduced with a metal reducing agent potassium borohydride to obtain crude proline, which is finally separated and purified to obtain crude L-proline.In preferred embodiments, the proline of the N-acylated proline is obtained by fermentation. Such processes are well-known in the art, for example as described in US4444885 A. More preferably a microorganism is used for fermentation, such as a bacterium, preferably selected from the group consisting of Corynebacterium, Arthrobacter, Brevibacterium, and Microbacterium or a yeast, such as Saccharomyces. The fermentatively derived proline acids possess at least 10%, at least 20%, at least 40%, at least 70%, at least 95% or even 100% non-fossil derived carbon atoms.Also, glutamate or glutamic acid, starter compounds for N-acylated glutamate, can be derived by chemical synthesis or by fermentation. The chemical synthesis may involve hydrolysis of vegetable proteins with hydrochloric acid to disrupt peptide bonds or direct chemical synthesis with acrylonitrile.However, preferably the glutamate or glutamic acid is derived from fermentation. The producing organism may be chosen among the genus of bacteria including Corynebacterium glutamicum, Brevibacterium lactofermentum, and Brevibacterium flavum. The fermentatively derived glutamate or glutamic acid possess at least 10%, at least 20%, at least 40%, at least 70%, at least 95% or even 100% non-fossil derived carbon atoms.The above-described amino acids proline and glutamate can be reacted with fatty acids to arrive at the N-acylated proline and N-acylated glutamate of the inventive composition. The fatty acids are aliphatic, saturated or unsaturated, linear or branched compounds comprising 8 to 18 carbon atoms. The fatty acids are preferably derived from animal oils, such as fish oil, or plant oils, such as coconut oil, palm kernel oil, palm oil, seed oils, in particular peanut, olive oil, corn oil, soya bean oil, sunflower oil, sunflower seed oil, linseed oil and rapeseed oil. Thus, the fatty acids possess at least 10%, at least 20%, at least 40%, at least 70%, at least 95% or even 100% non-fossil derived carbon atoms.Thus, in preferred embodiments the amount of non-fossil carbon atoms in one or all of the N-acylated amino acids of the inventive composition is at least 10%, at least 20%, at least 40%, at least 70%, at least 95% or they solely comprise non-fossil derived carbon atoms compared to the total amount of carbon atoms in the N-acylated amino acids.The integer “n” is preferably 1 , 2, 3, 4 or 5.The term "salts of the inventive compounds”, as used herein, refers to compound complexes having an anionic part and a cationic part. The amino acid, proline or glutamate, represents the anionic part (usually in form of a deprotonated carboxyl group). It is noted that the stoichiometric ratios between the anionic and cationic part may be 1 : 1 , but also ratios, such as 1 :2, 1 :3, 2:3, 2:1 , 3:1 and 3:2 are possible. In further preferred embodiments, at2410746 least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99% or 100% of the amino acids of the inventive composition are represent as a salt.Each of the N-acylated prolines and the N-acylated glutamates of the inventive composition comprises ester bonds. It is expected that these ester bonds can be hydrolyzed by enzymes of microorganisms, forming non-toxic degradation products, including proline or glutamate and fatty acids. Therefore, significant biodegradability rates can be expected for the composition of the invention and in preferred embodiments the inventive composition demonstrates at least 20%, preferably at least 40%, more preferably at least 60% or even more preferably at least 80% biodegradability according to standard OECD 301 F within 56 days, preferably within 28 days. For the purposes of this invention, aerobic biodegradation in wastewater according to OECD 301 F is expressed as a percentage of the theoretical oxygen demand (ThOD, which is measured by the elemental analysis of the compound of interest), which is needed to completely biodegrade the polymer sample. Thus, the amount of oxygen taken up by the microbial population during biodegradation of the test substance (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD. The obtained values are preferably measured in triplicate using the OECD 301 F manometric respirometry method. The consumption of oxygen is determined by measuring the change in pressure in the apparatus using an OxiTop® C (Xylem 35 Analytics Germany Sales GmbH & Co KG).

[0042] of Reference RF1.241074ExamplesI) Synthesis:GeneralA long-chain aliphatic fatty acid chloride is dissolved in acetone and added to an aqueous solution of a ringcomprising amino acid in presence of potassium carbonate. After work-up, the obtained products show an acylation degree of at least 90%. Optionally, fatty acid, which is generated by hydrolysis of the fatty acid chloride, is removed by distillation.Inventive example (IE)I E1 : N-cocoylproline sodium salt : N-cocoylglutamate sodium salt = 95 : 5C11 H23 / C13H2795% w / w N-cocoylproline sodium salt : 5% w / w : N-cocoylglutamate sodium salt (each with R' = C11H23 1 C13H27 = 75 / 25)I) L-Proline (Pyrrolidine-2-carboxylic acid, 10.5 g, 91 mmol, 1 eq) and potassium carbonate (39.2 g, 283 mmol, 3.1 eq) was dissolved in water (400 ml) in a 750 ml vessel and cooled to 0 °C. A mixture of lauroyl chloride (n-dodecanoic acid chloride, 15.0 g, 69 mmol, 0,75 eq) and myristoyl chloride (n-tetradecanoic acid chloride, 5.6 g, 23 mmol, 0.25 eq) in acetone (200 ml) was added dropwise at -1 - 2°C within 30 minutes. Reaction mixture was stirred and warmed to 22°C within 180 minutes. Acetone was removed under mellow temperature and reduced24107417 pressure (32°C, 100 mbar), the remaining solution was acidified to pH = 1 with concentrated HCI (58.6 g). The mixture was extracted 3 times using ethyl acetate. The combined organic layers were washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under mellow temperature and reduced pressure (32°C, 6 mbar), the residue was solved in ethanol (200 ml). A solution of sodium hydroxide (4.0 g) in ethanol (100 ml) was added and the mixture was stirred for 30 minutes. Ethanol was removed under mellow temperature and reduced pressure (32°C, 6 mbar). The slightly yellowish, waxlike product was analyzed by proton NMR spectroscopy and structure was confirmed.In case of larger amounts (>10 mol%) of fatty acid as by-product one can purify the compound in the following way:The crude product was acidified with HCI (pH = 1) and then purified by a "Kugelrohr” distillation. To separate N- cocoyl proli nic acid and cocoyl acid (mixture of 0.75 eq dodecanoic acid and 0.25 eq tetradecanoic acid) the product mixture (25 g with 20-30 mol% of cocoyl acid) was pre-distilled on a rotary evaporator at 50°C and 6 mbar. Then, the mixture was filled in the terminal bulb of the "Kugelrohr” and the pressure was reduced to 0.2 mbar. The tube furnace was heated to 120°C and the temperature was further increased up to 190°C. The remaining product in the terminal bulb (17.2 g) was dissolved in water and sodium hydroxide was added to adjust the pH to 7. The solution comprises 20 wt% surfactant in water. The product was analyzed by proton NMR spectroscopy and structure was confirmed.II) Glutamic acid (2-Aminopentanedioic acid, 13 g, 88.4 mmol, 1 eq) and potassium carbonate (37.9 g, 274 mmol, 3, 1 eq) was dissolved in water (400 ml) in a 750 ml vessel and cooled to 0 °C. A mixture of lauroyl chloride (n-Dodecanoic acid chloride, 14.5 g, 66.3 mmol, 0.75 eq) and myristoyl chloride (n-tetradecanoic acid chloride, 5.5 g, 22.1 mmol, 0.25 eq) in acetone (200 ml) was added dropwise at -1 - 2°C within 30 minutes. Reaction mixture was stirred and warmed to 22°C within 180 minutes. Acetone was removed under mellow temperature and reduced pressure (32°C, 100 mbar), the remaining solution was acidified to pH = 1 with concentrated HCI (52.8 g). The mixture was extracted 3 times using ethyl acetate. The combined organic layers were washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under mellow temperature and reduced pressure (32°C, 6 mbar). The crude product is recrystallized two times in toluene (50 ml) and solved in ethanol (100 ml). A solution of sodium hydroxide (7 g) in ethanol (100 ml) was added and the mixture was stirred for 30 minutes. Ethanol was removed under mellow temperature and reduced pressure (32°C, 6 mbar). The crystalline, white product was analyzed by proton NMR spectroscopy.In case of larger amounts (>10 mol%) of fatty acid as by-product one can purify the compound in the following way:The crude product was acidified with HCI (pH = 1) and then purified by a "Kugelrohr” distillation. To separate N- Cocoylglutamic acid and cocoyl acid (mixture of 0.75 eq dodecanoic acid and 0.25 eq tetradecanoic acid) the product mixture (26 g with 20-30 mol% of cocoyl acid) was pre-distilled on a rotary evaporator at 50°C and 6 mbar. Then, the mixture was filled in the terminal bulb of the "Kugelrohr” and the pressure was reduced to 0.2 mbar. The tube furnace was heated to 120°C and the temperature was further increased up to 190°C. The remaining product in the terminal bulb (18 g) was dissolved in water and sodium hydroxide was added to adjust the pH to 7. The24107418 solution comprises 20 wt% surfactant in water. The product was analyzed by proton NMR spectroscopy and structure was confirmed.N-cocoylprolin sodium salt (5.97 g, 95 wt%) and N-cocoylglutamic sodium salt (0.28 g, 5 wt%) where dissolved in the exact amount of water (23.87 g) that was needed to yield a clear solution comprising 20 wt% of active content.The above mixture is called the Inventive Example 1 (IE1).Comparative examplesCE2: N-Cocoyllysine sodium saltNaLysine (2,6-Diaminohexanoic acid, 20.0 g, 137 mmol, 1 eq) and potassium carbonate (58.6 g, 424 mmol, 3.1 eq) was dissolved in water (600 ml) in a 1 ,000 ml vessel and cooled to 0 °C. A mixture of lauroyl chloride (n-dodecanoyl chloride, 22.5 g, 103 mmol, 0.75 eq) and myristoyl chloride (n-tetradecanoyl chloride, 8.4 g, 34.2 mmol, 0.25 eq) in acetone (300 ml) was added dropwise at -1 - 2°C within 30 minutes. Reaction mixture was stirred and warmed to 22°C within 180 minutes. Acetone was removed under mellow temperature and reduced pressure (32°C, 100 mbar), the remaining solution was acidified to pH = 1 with concentrated HCI (58.7 g). The precipitate that formed was collected using vacuum filtration, washed with water, dried and solved in ethanol (500 ml). A solution of sodium hydroxide (3.8 g) in ethanol (100 ml) was added and the mixture was stirred for 30 minutes. Ethanol was removed under mellow temperature and reduced pressure (32°C, 6 mbar). The product was dissolved in water to obtain a solution of 20 wt% surfactant in water.24107419CE3: C12C14 - 2 EO - SO4NaThe well-known detergent surfactant alkyl ether sulfate (AES) sodium salt C12C14 - 2 EO - SC^Na (commercially sold as Texapon N70) was used for comparative studies. The C12C14 alkyl chain is linear and saturated. The average carbon number is around 12.5 carbon atoms in the alkyl group. A linear C12C14 fatty alcohol is reacted with ca. 2 eq of ethylene oxide by use of KOH catalysis. The obtained alkyl ethoxylate is sulfated with sulfur trioxide in a falling film reactor (sulfation degrees are 90% and higher). The intermediate semi sulfuric acid ester C12C14- 2EO-OSO3H is then neutralized with a base. In this case it was neutralized with NaOH.II) Functional tests:The amounts and concentrations of surfactants in the following tests refer to active material.A) Wetting timeAs shown for IE1 in Table 1 , the inventive surfactants wet a cotton rag in 26 seconds at 20°C (test according to EN 1772, cotton rag is put below surface of aqueous surfactant solution, once the rag is fully wetted and air is released from cotton rag it starts to sink to the bottom; the time is noted once the cotton rag starts to sink). The comparative example CE2 based on lysine requires more than 300 seconds and is a very bad wetter. The detergent surfactant alkyl ether sulfate sodium salt C12C14 - 2 EO - SO4Na (45 seconds in comparative example CE3) also needs significantly longer than the inventive surfactants. The inventive surfactants are almost two-times faster to fully wet a cotton rag.Table 1 : Wetting of cotton rag at 20°C in hard water (10 °dH)B) FoamabilityAs shown in table 2, inventive compounds of IE1 show a much better foamability (450 ml in inventive example IE1) at 40°C in hard water (10° dH) using 2 g of material per liter in a test regarding whipped foam (EN 12728, DIN 53902) compared to other, acyclic, modified amino acids, such as N-Cocoyllysine sodium salt (30 ml in comparative example CE2). The detergent surfactant alkyl ether sulfate sodium salt C12C14 - 2 EO - SO4Na shows the best foamability (725 ml in comparative example CE3), however, the inventive structures (inventive example IE1) are surprisingly close regarding foamability. A good foamability is of interest e.g., for hand dishwashing in presence of hardness (such as calcium ions).24107420Table 2 Foamability of 2 g surfactant per liter of hard water (10° dH) at 40°C using whipped foam methodC) Dynamic surface tensionTable 3 underlines that the inventive structures (I E1) show after 0.1 seconds in hard water a much lower dynamic surface tension (43.1 mN / m in inventive example IE1 ) compared to other, acyclic, modified amino acids such as N- Cocoy llysine sodium salt (68.7 mN / m in comparative example CE2). Such lower dynamic surface tension indicates that the surfactant is fast at interfaces e.g., at oil-water interface and can start the removal of e.g., oil earlier. This is of relevance for l&l processes, laundry, and dishwashing. The detergent surfactant alkyl ether sulfate sodium salt C12C14 - 2 EO - SC>4Na shows an even slightly lower dynamic interfacial tension (42.1 mN / m in comparative example CE3), however the inventive structures (inventive example IE1) are surprisingly close to a commercial standard cleaning surfactant regarding dynamic interfacial tension.Table 3 Dynamic surface tension of 1 g surfactant per liter of hard water (10° dH) at room temperature after 0.1 sD) Interfacial tensionTable 4 describes that inventive structures (IE1) show in hard water after 3 minutes lower interfacial tension against olive oil or n-hexadecane (0.21 mN / m and 1.09 mN / m in inventive example IE1) compared to other, acyclic, modified amino acids such as N-Cocoyllysine sodium salt (11 mN / m and 4.3 mN / m in comparative example CE2). Such lower interfacial tension indicates that the surfactant can remove oil in a better way. Olive oil is a triglyceride and thereby a model oil for soil in laundry or dishwashing; n-hexadecane is a model oil for aliphatic oils e.g., from the lubricant sector. This is of relevance for l&l processes, laundry, and dishwashing. A comparison with detergent surfactant alkyl ether sulfate sodium salt C12C14 - 2 EO - SO4Na (0.6 mN / m and 0.8 mN / m in comparative example CE3) shows that the inventive structures (inventive example IE1) are on the same level regarding interfacial tension or even lower.24107421Table 4 Interfacial tension of 1 g surfactant per liter of hard water (10° dH) at room temperature after 3 minE) Mineral oil removalTable 5 underlines that the inventive surfactants (IE1) show in hard water a better removal of mineral oil from a copper surface after 25 minutes (73.9% of oil removed in example IE1) compared to other, acyclic, modified amino acids such as N-Cocoyllysine sodium salt (40.3% of oil in comparative example CE2). The detergent surfactant alkyl ether sulfate sodium salt C12C14 - 2 EC - SO4Na (69.9% of oil in comparative example CE3) removes less oil than the inventive surfactants.Table 5: Mineral oil removal from copper surface by use of 1 g surfactant per liter of hard water (10° dH) at pH = 9 and at room temperature after 25 minF) BiodegradabilityTable 6 shows a significant biodegradability of 81 % within 28 days under aerobic conditions using a sludge from a communal sewage plant in Germany for the inventive surfactants IE1. Test conditions according to OECD 301 F were used as described above. The value of 81 % within 28 days fulfills the requirement of min. 60% within 28 days for a detergent surfactant.Table 6: Biodegradability within 28 days under aerobic conditions with sludge from communal sewage plant24107422G) Washtests including enzymesThe washing test was conducted with a protease (Lavergy Pro 114 LS was used as protease). Following detergent formulations were prepared on weight basis. Beside the previously described inventive surfactant mixture, detergent surfactants such as C10-C13-Ph-SO3H (Maranil DBS / LC from BASF), C13C15 - 7 EO (Lutensol AO7 from BASF), and 012014 - 2 EO - S04Na (Texapon N70) were used. The surfactant amounts in formulation table below refer to active material. The rest is as is. Edenor K 12-18 (from KLK Oleo) is a mixture of fatty acids with 12 to 18 carbon atoms. Formulation E is another example for a typical detergent formulation. Formulation F is Formulation E without the alkyl ether sulfate. Formulation G is Formulation F with the inventive surfactant mixture (N-cocoylproline sodium salt : N-cocoylglutamate sodium salt = 95 : 5 (as described above each with R' = C11 H23 / C13H27 = 75 / 25, and M+= Na+, IE1). Formulation H is Formulation F with the comparative surfactant (N- Cocoyllysine sodium salt, CE2).The washing performance was determined as follows:The L*, a* b* values of the single stains on multi soil monitors are measured before wash with a MACH 5 from CFT / Color consult. Then the fabrics are washed together with cotton ballast fabric and 20 steel balls at 30°C in water with defined water hardness. After the wash the fabrics are rinsed, spin-dried and dried in the air.24107423The washing performance for the single stains is determined by measuring the L*, a* b* values with a MACH 5 from CFT / Color consult after drying. The dE value is calculated from the single values before and after wash. The 2 stains from the monitor are summed up. The higher the value, the better the performance. The experiment was repeated, and the average values were used. The stains cover typical kinds of soil, which are addressed by a protease: egg and blood.Washing conditions:Producer: wfk-Testgewebe, Christenfeld 10, 41379 Briiggen; Swissatest Testmaterialien AG, MbvenstraBe 12, CH-9015 St. Gallen; Center for Testmaterials B.V., Stoomloggerweg 11 , NL-3133 VlaardingenTable 7 shows result of detergency with a protease in a launder-o-meter test at 30°C using each 2 stains on fabric (CFT-C-S-01, CFT-C-S-39), 3 g / l formulation and water with hardness of 2.5 mmol. Steel balls were added to simulate impact of mechanics and fabric was washed for 60 minutes. Remission of fabric before and after washing was detected and difference (in DE) was noted. As shown in example IE1 , the formulation G with the inventive surfactant mixture IE1 (48.1 delta E values at 30°C) removes the 2 stains much better than the formulation E comprising the classical detergent surfactant alkyl ether sulfate (47.3 delta E values at 20°C). At 30°C, the inventive surfactant IE1 (48.1 delta E values at 30°C) is surprisingly much better than the comparative surfactant CE2 (Formulation H, 43.4 delta E values at 30°C). Formulation F provides even a better stain removal (47.3 delta E values at 30°C) than the comparative surfactant CE2. It is noted that the inventive surfactant mixture is provides a good cleaning results at low washing temperature of 30°C compared to standard surfactant. This provides a solution for dioxane-free detergent formulation as alkyl ether sulfates can always be a source of dioxane formation, which is at the end a contribution to sustainability.Table 7: Detergency with protease in a launder-o-meter test at 30°C using 2 stains (CFT-C-S-01 , CFT-C-S-38) on fabrics after 60 min with and without surfactant in hard waterThe next washing test was conducted with an amylase (Lavergy A Star was used as amylase). Following detergent formulations were prepared on weight basis. Beside the previously described inventive surfactant mixture, detergent surfactants such as C10-C13-Ph-SO3H (Maranil DBS / LC from BASF), C13C15 - 7 EO (Lutensol AO7 from BASF), and C12C14 - 2 EO - SO4Na (Texapon N70) were used. The surfactant amounts in formulation table below refer to active material. The rest is as is. Edenor K 12-18 (from KLK Oleo) is a mixture of fatty acids with 12 to 18 carbon atoms. Formulation I is another example for a typical detergent formulation. Formulation J is Formulation I without the alkyl ether sulfate.

Formulation L is Formulation J with the comparative surfactant N- Cocoy llysine sodium salt, CE2).25The washing performance was determined as follows:The L*, a* b* values of the single stains on multi soil monitors are measured before wash with a MACH 5 from CFT / Color consult.

Steel balls were added to simulate impact of mechanics and fabric was washed for 60 minutes. Remission of fabric before and after washing was detected and difference (in DE) was noted. As shown in example IE1 , the formulation K with the inventive surfactant mixture IE1 (63.8 delta E values at 30°C) removes the 2 stains much better than the formulation I comprising the classical detergent surfactant alkyl ether sulfate (61.7 delta E values at 30°C). At 30°C, the inventive surfactant IE1 (63.8 delta E values at 30°C) is also better than the comparative surfactant CE2 (Formulation L, 62.3 delta E values24107426 at 30°C). Formulation J provides a similar stain removal (62.3 delta E values at 30°C) than the comparative surfactant CE2. It is noted that the inventive surfactant mixture is provides a good cleaning results at low washing temperature of 30°C compared to standard surfactant.
