[0042] Herein, several embodiments of the present invention will be described in detail by the following examples.
[0043] Synthetic S1: Hydrophobically modified cellulose ether-based material In a 500 mL four-necked round-bottom flask, add 27.31 g (containing 25.00 g) of cellulose ether substrate (M, which has a weight-average molecular weight of 1,400,000 daltons and is available from The Dow Chemical Company). WCELLOSIZE (trademark) HEC QP-52000H hydroxyethylcellulose and 125.46 g of isopropyl alcohol were added together with 16.94 g of deionized water. The flask was fitted with a nitrogen inlet connected to a 60 mL pressure-equalizing funnel, a rubber septum cap, a stirring paddle connected to an electric motor, and a Claisen adapter connected to a Friedrich condenser having a mineral oil foaming outlet. 2.47 g of HAGE16 containing 7.20 g of isopropyl alcohol was added to the addition funnel. While stirring the slurry, the headspace of the flask was purged with a slow, steady flow of nitrogen for 1 hour to remove all entrained oxygen from the apparatus. A flow rate of approximately 1 bubble per second was sufficient. While stirring under nitrogen, 1.60 g of 50% sodium hydroxide aqueous solution was added dropwise over 2 minutes using a plastic syringe. After stirring for 1 hour, hexadecyl glycidyl ether (HAGE16) was added dropwise over 3 minutes via an addition funnel. The solution was stirred under nitrogen for 20 minutes, and then heat was applied using a heating mantle. The solution was heated under nitrogen while stirring and held for 4.5 hours. The slurry was then cooled in an ice bath while maintaining a positive nitrogen pressure inside the flask. The slurry was neutralized by adding 2.16 g of glacial acetic acid using a syringe, and the resulting slurry was stirred under nitrogen for 10 minutes. The polymer was recovered by vacuum filtration through a large frit metal Buchner funnel. The filtration cake was washed in a Buchner funnel by stirring the slurry in the funnel for 5 minutes with a specific washing solvent, and the washing solution was then vacuum removed: 36 g of water in 164 g of isopropyl alcohol, 20 g of water in 180 g of isopropyl alcohol, and 200 g of isopropyl alcohol for drying. To impart cold water dispersibility to the final polymer, 0.44 g of a 40% glyoxal aqueous solution and 0.15 g of acetic acid were added to the final drying wash solution. The polymer was recovered by vacuum filtration, air-dried briefly, and then dried overnight under vacuum at 50°C.
[0044] Synthetic S2: Modified Carbohydrate Polymer 22.55 g (containing 19.59 g) of the synthetic S1 product and 168.48 g of isopropyl alcohol were added to a 500 mL four-necked round-bottom flask along with 30.13 g of deionized water. The flask was fitted with a Claisen adapter connected to a Friedrich condenser having a nitrogen inlet connected to a 60 mL pressure-equalizing funnel, a rubber septum cap, a stirring paddle connected to an electric motor, and a mineral oil foaming outlet. 15.12 g of QUAB151 was added to the addition funnel. While stirring the slurry, the headspace of the flask was purged with a slow, steady flow of nitrogen for 1 hour to remove all entrained oxygen from the apparatus. A flow rate of approximately 1 bubble per second was sufficient. While stirring under nitrogen, 2.40 g of 25% sodium hydroxide aqueous solution was added dropwise over 2 minutes using a plastic syringe. After stirring for 1 hour, QUAB151 was added dropwise over 3 minutes via the addition funnel. The solution was stirred under nitrogen for 20 minutes, and then heat was applied using a heating mantle. The solution was heated to 55°C while stirring under nitrogen and held for 1.5 hours. The slurry was then cooled in an ice bath while maintaining positive nitrogen pressure in the flask. The slurry was neutralized by adding 2.50 g of glacial acetic acid using a syringe, and the resulting slurry was stirred under nitrogen for 10 minutes. The polymer was recovered by vacuum filtration through a large frit metal Buchner funnel. The filtered cake was washed in the Buchner funnel by stirring the slurry in the funnel for 5 minutes with a specific washing solvent, and the washing solution was then vacuum removed: 36 g of water in 164 g of isopropyl alcohol, 20 g of water in 180 g of isopropyl alcohol, and 200 g of isopropyl alcohol for drying. To impart cold water dispersibility to the final polymer, 0.44 g of 40% aqueous glyoxal solution and 0.15 g of acetic acid were added to the final drying washing solution. The polymer was recovered by vacuum filtration, air-dried briefly, and dried overnight under vacuum at 50°C. The resulting cationic hmHEC polymer had a volatile matter content of 3.77 wt%, an ash content of 2.41 wt% (as sodium chloride), and a Kjeldahl nitrogen content of 1.76 wt%.The viscosity of a 1% solution (corrected for ash and volatile substances) was measured in 6.31 seconds using a TA Instruments DHR-3 rheometer with a 40 mm, 2.0° stainless steel cone and plate sensor at 25.0°C. -1 Measurements revealed a value of 6,268 mPa·s.

Each load required 10 - 11 liters of wash water with 25° French hardness and 23 TAC. The soil used was 4 SBL 2004. Each load of laundry contained 6 pillow covers, 5 bath towels, and 1 bed sheet. Each load was pre-washed (3 cycles) before testing.

Both monitors with stains were dried overnight on a drying line. The stains were measured using a MACH5+ instrument (L, a, and b). The results are shown in Table 8, where ΔE * is according to the following formula. ΔE * = ΔE aw - ΔE bw In the formula, ΔE aw is measured from the fabric after washing, and ΔE bw is measured from the fabric before washing. A higher ΔE * corresponds to better primary washing performance.
