Chemical formula

[0004] Liquid and gel-form laundry detergents that provide excellent overall cleaning are desirable to consumers. Such laundry detergents typically contain surfactants among other ingredients to achieve the desired cleaning benefits for consumers. Nevertheless, due to the increasing environmental sensitivity and rising material costs, there is a growing trend to reduce the use of surfactants in laundry detergents. As a result, the detergent industry is seeking ways to reduce the amount of surfactant per unit dose of laundry detergent while maintaining the overall cleaning performance.

[0005] One approach to reducing the unit dose of surfactant is to incorporate polymers into liquid detergent formulations, as described by Boutique et al. in U.S. Patent Application Publication No. 2009 / 0005288. Boutique et al. disclose graft copolymers of polyethylene, polypropylene, or polybutylene oxide and vinyl acetate in a weight ratio of about 1:0.2 to about 1:10 for use in liquid or gel laundry detergent formulations having about 2 to about 20% by weight of surfactant.

[0006] Nevertheless, there remains a continuing need for liquid laundry detergent formulations that exhibit maintained primary cleaning performance at reduced surfactant loadings and preferably also provide improved soil redeposition prevention performance. There is also a continuing need for new cleaning boosters that have improved biodegradability according to the OECD 301F protocol when compared to conventional cleaning boosters.

[0054] Synthesis of S7 - S10: Preparation of alkoxylate polymers In Syntheses S7 - S10, CH3O-(EO) m (PO) nThe alkoxylate polymer was prepared by -H in a Symyx Parallel Pressure Reactor (PPR (registered trademark)) equipped with a glass insert and a removable polyether ether ketone (PEEK) paddle for mechanical stirring. Both the glass insert and the removable PEEK stirring paddle were dried overnight in a vacuum oven at 125 °C prior to the reaction. By ethoxylation of 2-methoxyethanol (manufactured by Sigma-Aldrich), an ethoxylation intermediate of type CH3O-(EO) m -H was prepared. Under nitrogen, a stock solution was prepared by dissolving potassium hydride in an amount of about 3 wt% based on the weight of 2-methoxyethanol in 2-methoxyethanol. Next, a calculated amount of the stock solution was added to the glass insert under nitrogen. Then, the glass insert was loaded into the reactor, followed by attaching the stirring paddle.

[0055] Next, the reactor was sealed, heated to 120 °C, and pressurized to 345 kPa with nitrogen. Then, ethylene oxide was delivered to the reactor in several injections via an Isco syringe pump equipped with a robotic control needle and a compressed gas microvalve connected to the reactor. The total amount of ethylene oxide added to the reactor was calculated to provide a (EO) block of the desired length assuming that the ethylene oxide added to the reactor was completely consumed. After the addition of ethylene oxide, the temperature was maintained at 120 °C and the reaction mixture was stirred for 4 hours. Then, the contents of the reactor were cooled. The reactor was vented and purged with nitrogen to remove any residual ethylene oxide. n Next, the reactor was heated to 50 °C and pressurized with nitrogen to a pressure of 345 kPa. Then, the reactor was filled with propylene oxide via the Isco syringe pump. The amount of propylene oxide added to the reactor was calculated to provide a (PO) of the desired length of the target substance assuming that the propylene oxide added to the reactor was completely consumed.

[0056] n ​It was calculated to correspond to the block. After the addition of propylene oxide, the temperature was raised to 115 °C and maintained at that temperature while the contents of the reactor were stirred for 20 hours. Then, the contents of the reactor were cooled. The reactor was evacuated and purged with nitrogen to remove any residual ethylene oxide. The product from the reactor was used without further purification. As reported in Table 1, the molecular weight of the recovered product was determined by GPC and the composition was determined 13 by 13C NMR.

The flask was sealed with silicone grease, purged with nitrogen, and then heated in an OptiTHERM® Reaction Block attached to an IKA magnetic heating plate at a set point temperature of 120 °C. After the contents of the flask reached an internal temperature of 120 °C, a vacuum was applied to the flask contents via a mechanical pump with an intermediate solvent trap cooled by dry ice in a Dewar bin. The mixing speed setting was constant at 230 rpm since the contents of the flask maintained a constant viscosity during heating. The contents of the flask were held under vacuum at a temperature of 119 - 121 °C for 8.5 hours. The flask contents were then cooled and characterized. The degree of substitution of the methyl ester groups was estimated by the integrated peaks in the quantitative 13C NMR spectrum for the methyl groups of the methyl ester (51.5 ppm) and the α-methylene groups on the heptanediamine-dimethyl maleate adduct (38.1 ppm). This ratio was 0.12:1, and since the original unreacted heptanediamine-dimethyl maleate adduct had a methyl ester:α-methylene ratio of 2.18:1, this suggests that approximately 94% of the methyl groups were converted.

The washed fabric was rinsed in an Eberbach E6000 reciprocating shaker at 260 osc / min pm for 5 minutes with 300 mL of 100 ppm (2 / 1 Ca 2+ / Mg 2+ ) hardness-adjusted water at ambient temperature. The soiled fabric and soiled ballast used in the test were PCS-S-132 high-identification sebum BEY pigment and PCS-S-94 sebum / dust ASTM stain from Testfabrics sewn onto pre-shrunk cotton interlock fabric. The size of the cotton interlock was 5×5 cm. The size of the stained specimen was 2.5×3 cm. One 5×5 cm section of SBL-CFT soiled ballast was added to each canister to provide a baseline stain for the wash solution. The total surfactant concentration in the wash liquor was 200 ppm.
