^{Attorney Docket No. 84991-WO-PCT} AQUEOUS LAUNDRY DETERGENT COMPOSITION [0001] The present invention relates to an aqueous laundry detergent composition. In particular, the present invention relates to an aqueous laundry detergent composition, comprising: water; a cleaning surfactant; wherein the cleaning surfactant comprises a blend of a nonionic surfactant and an anionic surfactant; wherein the anionic surfactant comprises an alcohol ethoxysulfate surfactant of formula I (I) wherein each R ¹ sum of the carbon 1 atoms in R and to a charge of the -SO3- anion of formula I; and wherein n is 1 in 95 to 100 mol% of the alcohol ethoxysulfate surfactant of formula I. [0002] Aqueous laundry detergent formulations frequently include alkyl ethoxy sulfate anionic surfactants (e.g., alcohol ethoxysulfate surfactants). However, such surfactants have been associated with undesirable 1,4 dioxane content. Regulators are increasingly restricting the amount of 1,4 dioxane that may be present in consumer products. For example, New York State has banned all but trace amounts of 1,4 dioxane in cleaning products. Typically, a consumer product must contain less than 10 parts per million by weight (ppm) of 1,4 dioxane to be compliant with the regulations. One contributor of the unintended incorporation of 1,4 dioxane in consumer products can be the inclusion of alkyl ethoxy sulfate anionic surfactants. [0003] Inclusion of 1,4 dioxane in conventional AES surfactants is believed to occur at multiple points in time. A first point of 1,4 dioxane generation in conventional AES surfactants is believed to occur during the sulfation process of alcohol ethoxylates to make alcohol ethoxy sulfates. The alcohol ethoxylate intermediates for the production of conventional alcohol ethoxy sulfate surfactants are made via ethoxylation (i.e., the reaction of an alcohol with ethylene oxide) that typically results in a distribution of alcohol ethoxylate oligomers. It is believed that under the sulfation process conditions during the manufacture of conventional AES surfactants, 1,4 dioxane can form. A second point of 1,4 dioxane generation in association with conventional AES surfactants is believed to occur during handling and processing of the conventional AES surfactants. Handling and processing of conventional AES surfactants often involves acidic conditions at ambient, or elevated, ^{Attorney Docket No. 84991-WO-PCT} temperature. Prolonged exposure to acidic environments for conventional AES surfactants and their alcohol ethoxylate precursors may result in the formation of 1,4 dioxane. Further, exposure to elevated temperatures (e.g., up to 280 °C) during processing, storage and/or handling may result in the decomposition of conventional AES surfactants resulting in the formation of dioxane. [0004] Traditionally, 1,4 dioxane content in conventional AES surfactants and products incorporating such surfactants has been addressed by the use of stripping techniques. For example, where 1,4 dioxane concentrations are above a target threshold, a stripping process is employed to remove excess 1,4 dioxane from the conventional AES surfactants or product incorporating same. The stripping process is not only expensive and time consuming, but also is not a guarantee to meet the increasingly stringent regulatory requirements. Further, as 1,4 dioxane may form over time as a response to how the conventional AES surfactant or product is handled and further processed, any previously applied stripping techniques may be nullified by the generation of new 1,4 dioxane. As such, ensuring that a product comprising an AES surfactant is compliant with the appropriate regulations by the time it is sold to an end consumer is a difficult challenge. [0005] Accordingly, there remains a need for aqueous laundry detergent compositions having an anionic alcohol ethoxysulfate surfactant that resists forming 1,4-dioxane both during the sulfation process to form the surfactant and subsequently when the alcohol ethoxysulfate surfactant is exposed to elevated temperatures of up to 280 °C. [0006] The present invention provides an aqueous laundry detergent composition, comprising: water; a cleaning surfactant; wherein the cleaning surfactant comprises a blend of a nonionic surfactant and an anionic surfactant; wherein the anionic surfactant comprises an alcohol ethoxysulfate surfactant of formula I (I) wherein each R ¹ sum of the carbon atoms in R ¹ and R ² is 7 to 17; wherein M ⁺ is a cation balancing the negative charge of the -SO3- anion of formula I; and wherein n is 1 in 95 to 100 mol% of the alcohol ethoxysulfate surfactant of formula I. ^{Attorney Docket No. 84991-WO-PCT} [0007] The present invention provides an aqueous laundry detergent composition, comprising: water; a cleaning surfactant; wherein the cleaning surfactant comprises a blend of a nonionic surfactant and an anionic surfactant; wherein the anionic surfactant comprises an alcohol ethoxysulfate surfactant of formula I; wherein each R ¹ and R ² is independently a C1-16 alkyl group; wherein the sum of the carbon atoms in R ¹ and R ² is 7 to 17; wherein M ⁺ is a cation balancing the negative charge of the -SO ₃ - anion of formula I; wherein n is 1 in 95 to 100 mol% of the alcohol ethoxysulfate surfactant of formula I; and wherein the alcohol ethoxysulfate surfactant of formula I contains < 9 ppm of 1,4-dioxane.

^{Attorney Docket No. 84991-WO-PCT} Experimental Materials Material Description metallosilicate catalysts defined by BEA structure and having silica to 2 A S g ^{Attorney Docket No. 84991-WO-PCT} Synthesis S1: C12EO [0036] A 3 liter (L) 3-neck glass round bottom flask, equipped with an overhead stirred through the center neck, reflux condenser and a heating jacket was used for the etherification of 1-dodecene and monoethylene glycol with the catalyst. To ensure good mixing, a pitch blade impeller was used for agitation. A reaction mixture of 551.7 grams (g) ethylene glycol and 505.8 g 1-dodecene was prepared and loaded in the reactor together with 61 g catalyst in powdered form at 23 °C. The impeller stirring rate was set to be at 400 revolutions per minute (“rpm”). The reactor was heated to 135 °C in over the course of 30 minutes, held at 135 °C for 18 hours and then the reactor was cooled down to 23 °C by shutting off the heater. The reaction mixture was separated into a monoethylene glycol and catalyst phase and an olefin phase using a separation funnel. [0037] A distillation apparatus was constructed using a 1-liter round bottom flask connected to a short path distillation head with a thermometer adapter and a condenser with a vacuum adapter at the outlet. The distillation flask was heated in an aluminum block by an IKA heated stir-plate. The distillation pot was charged with the combined olefin phase and then stirring and vacuum were applied. Significant boiling was observed but no condensate was observed or collected. The temperature of the heating block was raised to 75 °C and unreacted dodecane was collected at a distillation head temperature of 25 °C to 50 °C and a pressure of 13.3-40 pascals (Pa). The heating block temperature was raised gradually to 140 °C and an intermediate fraction containing both monoether alcohol ethoxylates and dodecenes was recovered while the head temperature increased from 50 °C to 75 °C at a pressure of 13 Pa. The C12EO was collected at a head temperature of 70 °C to 115 °C and a pressure of 6 Pa to 33 Pa. The heating block temperature was raised gradually to 200 °C and an intermediate fraction containing both monoether alcohol ethoxylates and diether was collected while the head temperature increased from 115 °C to 130 °C at a pressure of 6 Pa. The distillation was discontinued and the diether, which remained in the pot, was collected. The C12EO was carried to the next sulfation process to make sulfate anionic surfactant. Synthesis S2: C14EO [0038] A 300 mL Parr reactor with a heating jacket and controller was used for the etherification of 1-tetradecene and monoethylene glycol with a catalyst. To ensure good mixing, a pitch blade impeller was used for agitation. [0039] The reaction mixture of 100.0 g monoethylene glycol and 100.0 g 1-tetradecene was prepared and loaded in the reactor together with 10.0 g powder form catalyst at 23 °C. The impeller stirring rate was set to be at least 600 rpm. The reactor was heated up to 135 °C in ^{Attorney Docket No. 84991-WO-PCT} 30 minutes, held at 135 °C for 6 hours and then the reactor was cooled down to room temperature by shutting off the heater. The reaction mixture was separated by a separation funnel. The reaction mixture was separated into a monoethylene glycol and catalyst phase and an olefin phase using a separation funnel. Fifteen batches were generated and the olefin phases were collected and combined for distillation. [0040] The same distillation apparatus as used in the Synthesis S1 was used for distillation of the C14EO. The distillation pot was charged with the products in the olefin phase from multiple batch reactor runs and then stirring and vacuum were applied. Significant boiling was observed but no condensate was observed or collected. The temperature of the heating block was raised to 95 °C and unreacted 1-tetradecene was collected at a distillation head temperature of 30 °C to 60 °C at a pressure of 27 Pa to 5 Pa. The heating block temperature was raised gradually to 170 °C and an intermediate fraction containing both monoether and tetradecene was recovered while the head temperature increased from 60 °C to 85 °C at a pressure of 7 Pa to 5 Pa. The C14EO was collected at a head temperature of 80 °C to 115 °C and a pressure of 8 Pa to 5 Pa. The distillation was discontinued when no more material would distill over with the pot temperature set at 170 °C. Synthesis S3: C12EO Sulfate [0041] All chemical manipulations were conducted under a dry nitrogen atmosphere. Prior to the experiment all glassware was heated in a laboratory oven to remove residual water. A 2-L three-neck round bottom flask was loaded with dichloromethane (500 mL) and C12EO prepared according to Synthesis S1 (40 g, 0.173 mol, 1.0 equivalents). The reaction flask was equipped with an overhead mechanical stirrer, additional funnel, and thermocouple. Next, chlorosulfonic acid (12.7 mL, 0.191 mol, 1.1 equivalents) was carefully loaded into the additional funnel. The reaction flask was then submerged into an ice-bath and allowed to cool for 20 minutes, down to 0 °C. Once the reaction was cooled, chlorosulfonic acid was added to the reaction flask dropwise, at a rate of approx.1.0 mL per minute, over approximately 20 minutes. During the addition of chlorosulfonic acid the reaction temperature did not exceed 5 °C. After the addition, the reaction was allowed to react, and the temperature was kept between 0 and 5 °C, for 3 hours. At this time, the reaction was neutralized by slow dropwise addition of an aqueous NaOH solution (18.0 g NaOH in 500 mL of water, 0.9 molar). The rate of addition was slow enough to not exceed 5 °C over the course of addition. The solution became basic after the addition of ~300 mL of 0.9 molar NaOH solution. Dichloromethane was then carefully removed from the biphasic reaction in vacuo. During the removal of the dichloromethane, a large amount of foam was observed. ^{Attorney Docket No. 84991-WO-PCT} Upon removal of the dichloromethane, the remaining aqueous solution was placed in a freeze drier/lyophilizer to yield the secondary alcohol ethoxylate sulfate product, C ₁₂ EO Sulfate, as a whiteish solid (61.9 grams). Synthesis S4: C14EO Sulfate [0042] All chemical manipulations were conducted under a dry nitrogen atmosphere. Prior to the experiment all glassware was heated in a laboratory oven to remove residual water. A 2-L three-neck round bottom flask was loaded with dichloromethane (500 mL) and C14EO prepared according to Synthesis S2 (50 g, 0.193 mol, 1.0 equivalents). The reaction flask was equipped with an overhead mechanical stirrer, additional funnel, and thermocouple. Next, chlorosulfonic acid (14.2 mL, 0.213 mol, 1.1 equivalents) was carefully loaded into the additional funnel. The reaction flask was then submerged into an ice-bath and allowed to cool for 20 minutes, down to 0 °C. Once the reaction was cooled, chlorosulfonic acid was added to the reaction flask dropwise, at a rate of approximately 1.0 mL per minute, over approximately 20 minutes. During the addition of chlorosulfonic acid the reaction temperature did not exceed 5 °C. After the addition, the reaction was allowed to react and the temperature was kept between 0 °C and 5 °C, for 3 hours. At this time, the reaction was neutralized by slow dropwise addition of aqueous NaOH (18.0 g in 500 mL of water, 0.9 molar). The rate of addition was slow enough to not exceed 5 °C over the course of addition. The solution became basic after the addition of about 400 mL of 0.9 molar NaOH solution. Dichloromethane was then carefully removed from the biphasic reaction in vacuo. During the removal of DCM, a large amount of foam was observed. Upon removal of DCM, the remaining aqueous solution was placed in a freeze drier/lyophilizer to give the secondary alcohol ethoxylate sulfate product (68.6 grams). Synthesis S5: ALEO1 Sulfate [0043] ALEO1 sulfate was prepared from ALEO1 in the same manner as described in Synthesis S3. Synthesis S6: SA3EO Sulfate [0044] SA3EO sulfate was prepared from SA3EO in the same manner as described in Synthesis S3. EO Distribution of Surfactants [0045] The distribution of EO adducts in the surfactants listed in TABLE 1 was determined by NMR or UHPLC-MS as noted using the methodology set forth below with the results provided in T ^ABLE 1. ^{Attorney Docket No. 84991-WO-PCT} Nuclear Magnetic Resonance EO Distribution Characterization (NMR) [0046] Samples of surfactant to be analyzed were prepared by dissolving the surfactant in deuterated dimethyl sulfoxide containing 0.025 M chromium (III) acetylacetonate. Nuclear magnetic resonance ( ¹³ C NMR) spectra of the samples were then collected on a Bruker AVANCE 400 MHz spectrometer equipped with a 10 mm cryo-probe set to 25 °C, with the following parameters: a 90°-pulse, inverse-gated decoupling, a 1.38 second acquisition time, and a 6.4 second recycle delay. 2048 scans were collected. The data was processed in MNOVA, and the chemical shifts were referenced to the solvent peak at 39.52 ppm. A DEPT-135 experiment was also acquired with the same parameters, but with a 2.0 second recycle delay, and 2048 acans. The ratios of different EO adducts are calculated by integrating and comparing the intensity of the ethylene oxide alcohol end groups from about 60-61 ppm, the ethylene oxide backbone groups from about 69-70 ppm, the ethylene oxide end group ether peak from about 71-72 ppm, the unreacted primary alcohol peaks from about 60-61 ppm, and the unreacted secondary alcohol peaks from about 65-66 ppm.

For the analysis, stock solutions were prepared at concentrations of 25 ppm in a 50/50 mixture of methanol/water. The alcohol ethoxylate samples were diluted 1:100 in 50/50 methanol/water in duplicate and vortexted for a few seconds. Then they were diluted 1:10 in 50/50 methonol/water to give a final dilution of 1:1,000. Ethal ^® LA-4 was the standard used for the commercial 1-mole sodium laureth sulfate and Ethal ^® LA-7 was the standard used for the commercial 3-mole sodium laureth sulfate. Calibration standards were prepared at 10 ppm, 5 ppm, 2 ppm and 1 ppm in 50/50 methanol/water. [0049] Alkyl sulfates were diluted from the 1:1,000 preparation in 50/50 methanol/water to give a final solution of 1:20,000. POLYSTEP ^® B-N-5 was used as the standard for the alkyl sulfate analysis. Standards were prepared in 50/50 methanol/water at concentrations of 5 ppm, 2 ppm, 1 ppm and 0.5 ppm. [0050] The samples were analyzed using a Waters ACQUITY ^® UPLC system equipped with a Waters BEH C181.7 μm 1 x 50 mm column. Mass spectrometry was conducted using a Waters LCT Premier TOF Mass Spectrometer with ESI. Measurements were conducted in both positive and negative ion mode. Each sample preparation was injected three times for analysis. The ratios of the different EO adducts were calculated by the peak area and are reported in TABLE 1. ^{Attorney Docket No. 84991-WO-PCT} TABLE 1 EO Adduct (i.e., n) (mol %) Surfactant 0 1 2+ [0051] At S5 had an n of 1 and no m ore than 5 mol% the oligomers have an n of ≥ 2. Specifically, ≥ 98 mol% of the oligomers of the products of Syntheses S4 and S5 had an n of 1 and ≤ 2 mol% of the oligomers had an n of ≥ 2. 1,4-Dioxane Content of Surfactants [0052] The 1,4-dioxane content in the surfactants listed in T ^ABLE 2 was determined by liquid injection low temperature gas chromatography-mass spectrometry (GC-MS) method for organic layer and liquid chromatography-mass spectrometry (LC-MS) method for aqueous layer as noted using the methodology set forth below with the results provided in TABLE 2. [0053] Gas chromatography-Mass spectrometry (GC-MS) conditions for organic layer 1,4-dioxane measurement: GC system Agilent 7890 GC system Anal tical column DB-130m x 032mm x 5 m ^{Attorney Docket No. 84991-WO-PCT} SIM Ion 88.00 m/z Dwell Time 250 [0054] Sta and diluting down to 0. - 00 ppm. [0055] Samples were prepared by mixing 3.3 g from the organic (DCM) layer of the crude process mixture and 6.7 g of THF, the solution was then allowed to shake for about 20 minutes. The solids were then centrifuged to the bottom and the supernatant was vialed in an autosampler vial. Spiked samples were prepared by spiking dioxane standard in THF into separate samples at 5-10 ppm. [0056] Liquid chromatography-mass spectrometry (LC-MS) conditions for aqueous layer 1,4-dioxane content measurement: Instrument Agilent 1260 Infinity Series w/ 6470 Triple Quad MS Column Waters Atlantis T33.0 x 150mm, 3 µm [005 d by preparing a dioxane in THF stock solution and the diluting down with water to 0.1-100 ppm. ^{Attorney Docket No. 84991-WO-PCT} Calculation of Dioxane Content Relative to Solids [0058] The ppm of dioxane content relative to solids content in the sample is calculated according to equation 1. ^^^^^^^^^^^^^ ^^ ^^^^^^^ ^^ ^^^^^^^^ ^ ^{^^} ^ ^^ ^^^^∗^^^^^ ^^^^^^^^ ^^^^^^ ^^^ ^ _{^^^^^^^^^ !^^^" ^^ ^^^"^^^ ^^#^} x 10' ^{(Eq. 1)} T ^ABLE 2 1,4 Dioxane (ppm) Sample Organic Phase (GC) 3 d secondary alcohol with an average of 3 moles of ethylene oxide per molecule contained 2 ppm of 1,4-dioxane in the organic phase at 110 ^o C and indicates the potential for structures having n ≥ 2 to produce 1,4-dioxane. Interestingly, when the inlet temperature was increased to 280 ^o C, the dioxane content of SA3EO sulfate increased from 2 ppm to 1,471 ppm 1,4-dioxane in the organic phase. This result indicates that sulfated surfactants having n ≥ 2 may develop observable 1,4-dioxane at 110 ^o C, but also that such surfactants may be unstable at elevated temperatures of 280 ^o C which could result in significant 1,4-dioxane formation. Similarly to SA3EO sulfate, gas chromatography results for the ALEO1 sulfate surfactant indicate the formation of > 9 ppm of 1,4-dioxane relative to the solids at 110 °C. Further, the ALEO1 sulfate surfactant also exhibited a large generation of 1,4-dioxane (259 ppm) at 280 °C, suggesting that the ALEO1 sulfate surfactant lacks stability at high temperatures. The inventive C12EO sulfate surfactant with ≥ 95 mol% having n of 1 and ≤ 5 mol% having n ≥ 2 demonstrates a low 1,4-dioxane content. Surprisingly, the inventive C12EO sulfate surfactant also demonstrates an extremely low 1,4-dioxane content and falls below the limit of detection (LOD) of the GC and LC methods. Using the LOD as a basis, this indicates that the dioxane content for the C12EO sulfate is < 1.6 ppm relative to solids, at 110 ^o C. Interestingly, the inventive C12EO sulfate, when the inlet temperature is increased to 280 °C, ^{Attorney Docket No. 84991-WO-PCT} the 1,4-dioxane content of the material is still less than 1 ppm (i.e., 0.58 ppm), which indicates that the inventive C12EO sulfate has increased thermal stability relative to the comparative materials. Comparative Examples CF1-CF2 and Examples F1-F3: Aqueous laundry Composition [0060] Aqueous laundry detergent compositions were prepared in each of Comparative Examples CF1-CF2 and Examples F1-F3 having the formulation as described in TABLE 3 and prepared by standard laundry formulation preparation procedure. The aqueous laundry detergent compositions were observed for formulation stability, with those exhibiting a phase separation being identified as not stable. The results of these observations are reported in TABLE 3. T ^ABLE 3 CF1 CF2 F1 F2 F3 Ingredient wt% (active) y [0061] The primary cleaning performance of the liquid laundry detergent formulations of Comparative Examples CF1-CF2 and Examples F1-F3 were assessed in a Launder- Ometer (SDL Atlas, Model M228AA) at a set test temperature of 22 °C using a 30 minute wash cycle. Twenty of the 1.2 liter canisters filled with 500 mL of hardness adjusted water at 100 ppm by mass with 2:1 Ca ²⁺ :Mg ²⁺ molar ratio were used for each run. The washed fabrics were rinsed in 300 mL of 100 ppm (2/1 Ca ²⁺ /Mg ²⁺ ) hardness adjusted water at ambient temperature for 5 minutes at 260 osc/min pm on an Eberbach E6000 reciprocal shaker. The stained fabrics and soiled ballasts used in the tests were PCS-S-132 high discriminative sebum BEY pigment and PCS-S-94 sebum/dust ASTM stains from Testfabrics stitched to a pre-shrunk cotton interlock fabric. The size of the cotton interlock was 5x5 cm. The stained ^{Attorney Docket No. 84991-WO-PCT} swatches were 2.5 x 3 cm. One 5 x 5 cm cut SBL-CFT soil ballast was added to each canister to provide baseline soil to the wash solution. The total surfactant concentration in the wash liquor was 200 ppm. Reflectance measurement and Stain Removal Index (SRI) [0062] The soil removal index (SRI) for each of the Liquid Laundry Detergent formulations evaluated in Primary Cleaning Performance Test were determined using ASTM Method D4265-14. The average SRI taken from 8 swatches per condition (two swatches per pot, 4 pots) is provided in TABLE 4. [0063] The L ^* , a ^* and b ^* values of the stained fabrics were measured pre and post wash with a Mach 5 spectrophotometer from Colour Consult. The L ^* , a ^* and b ^* values for the unwashed, unstained polycotton fabric was measured in the SRI calculations as follows: ^∆- ^{∗ ∗} ()* = _^./0.1^ − ∆- _^3/0.1^ ∗ × 100 ∆- wherein US is the fabric area, WS is the washed stain area, ΔE ^* (US-UF) is the color difference between the unwashed stain and the unwashed fabric and ΔE ^* (WS-UF) is the ΔE ^* color difference between the washed stain and the unwashed fabric. The value of ΔE ^* is calculated as ΔE ^* = (ΔL ^*2 + Δa ^*2 + Δb ^*2 ) ^½ .

The results are noted in T ^ABLE 6, wherein ΔE ^* is according to the equation ΔE ^* = ΔEaw - ΔEbw wherein ΔEaw is measured from fabrics after washing, and ΔEbw is measured from fabrics before washing. A higher ΔE ^* corresponds with better antiredeposition performance. For every fabric tested, the blend of the products of Syntheses S3 and S4 (1:1 wt%) provided the highest antiredeposition performance. TABLE 6 ΔE ^* )
