[0037] Herein, several embodiments of the present invention will be described in detail by the following examples.

[0038] The modified carbohydrate polymers in the examples were characterized as follows.

[0039] The volatile substances and ash content (measured as sodium chloride) were determined according to ASTM method D-2364.

[0040] The total Kjeldahl nitrogen content (TKN) was measured twice using a Buchi KjelMaster K-375 automated Kjeldahl analyzer. The TKN values ​​were corrected for volatile substances and ash content.

[0041] Example S1: Synthesis of cationic dextran polymer A 500 mL four-necked round-bottom flask equipped with a rubber septum cap, a nitrogen inlet, a pressure equalization funnel, a stirring paddle and motor, a subsurface thermocouple connected to a J-KEM controller, and a Friedrich condenser connected to a mineral oil bubbler was charged with dextran (30.33 g, Aldrich product no. D4876) and deionized water (160.75 g). A 70% aqueous solution of 2,3-epoxypropyltrimethylammonium chloride (27.13 g, QUAB® 151, available from SKW QUAB Chemicals) was charged into the funnel. The contents of the flask were stirred until the dextran dissolved in the deionized water. While stirring the contents, the apparatus was purged with nitrogen to remove any oxygen introduced into the system. The nitrogen flow rate was approximately 1 bubble per second. The mixture was purged with nitrogen while stirring for 1 hour. Using a plastic syringe, 4.76 g of a 25% sodium hydroxide aqueous solution was added to the contents of the flask over several minutes while stirring under nitrogen. The contents of the flask were then stirred under nitrogen for 30 minutes. Next, the contents of the addition funnel were added dropwise to the contents of the flask over several minutes while continuing to stir under nitrogen. After transferring the contents of the dropping funnel to the contents of the flask, the mixture was stirred for 5 minutes. The contents of the flask were then heated using a heating mantle controlled with a J-KEM controller set to 55°C. The contents of the flask were heated to 55°C and maintained there for 90 minutes. Next, the contents of the flask were cooled to room temperature while maintaining a positive nitrogen pressure inside the flask. When the contents of the flask reached room temperature, 2.50 g of acetic acid was added dropwise to the contents of the flask via syringe, and the contents of the flask were stirred for 5 minutes. The polymer was recovered by non-solvent precipitation of the aqueous solution with an excess amount of methanol. Next, the precipitated cationic dextran polymer was recovered by filtration through a Buchner funnel and dried overnight at 50°C in vacuum. The resulting branched-chain cationic dextran polymer was an off-white solid (24.3 g) with a volatile matter content of 3.65% and an ash content (as sodium chloride) of 0.37%. Volatile matter and ash content were measured as described in ASTM method D-2364.The Kjeldahl nitrogen content was measured using a Buchi KjelMaster K-375 automated analyzer and found to be 1.41% (corrected for volatile substances and ash), which corresponds to a trimethylammonium substitution degree (CS) of 0.19. The weight-average molecular weight M of the resulting cationic dextran polymer is... W That was 1,820,000 Daltons.

[0042] Comparative Examples CF1-CF4 and Example F1: Fabric Care Formulations Fabric care formulations containing the ingredients listed in Table 1 were prepared in Comparative Examples CF1 to CF4 and Example F1, respectively, using a standard laundry formulation preparation procedure.

[0043] [Table 1]

[0044] Fabric flexibility The fabric softening performance of the fabric care formulations of Comparative Examples CF1-CF4 and Example F1 was evaluated in a Kenmore brand top-load washing machine at a normal / regular setting, medium load, and a temperature of 70°F. A general laundry detergent (32.2g) was added for the wash cycle, and the fabric care formulation of Comparative Examples CF1-CF4 or Example F1 (25g) was added at the start of the rinse cycle. The fabric items treated in each test consisted of two cotton terry towels and ballast to bring the total load weight to 6 pounds. Once the washing machine cycle was complete, all ballast was removed from the washing machine and dried in a tumble dryer at high temperature until dry. Prior to analysis, the cotton terry towels were conditioned for 24 hours in a temperature and humidity chamber at 21°C and 65% relative humidity. After conditioning, at least four small pieces from each cotton terry towel were analyzed using a Phabrometer® system to evaluate their softness. The results are shown in Tables 2 and 3.
