[0049] Some embodiments of the present invention will now be described in detail in the following examples.

[0051] Volatile matter and ash content (measured as sodium chloride) were determined as described in ASTM Method D-2364.

[0053] Example S1: Synthesis of cationic dextran polymer

[0054] Add dextran (30.33 g; Aldrich product #D4876) and deionized water (160.75 g) to a 500 mL four-necked round-bottom flask equipped with a rubber serum cap, nitrogen inlet, pressure equalization feeding funnel, a stirrer and motor, a ground thermocouple connected to a J-KEM controller, and a Friedrich condenser connected to a mineral oil bubbler. Add 27.13 g of a 70% aqueous solution of 2,3-epoxypropyltrimethylammonium chloride to the feeding funnel. 151 (available from SKW QUABChemicals). Stir the contents of the flask until the dextran dissolves in the deionized water. While stirring, purge the system with nitrogen to displace any entrained oxygen. The nitrogen flow rate is approximately 1 bubble / second. Purge the mixture with nitrogen while stirring for one hour. Using a plastic syringe, add 4.76 g of a 25% sodium hydroxide aqueous solution to the contents of the flask over several minutes with stirring under nitrogen. Then stir the contents of the flask under nitrogen for 30 minutes. Then, with continuous stirring under nitrogen, add the contents of the feeding funnel dropwise to the contents of the flask over several minutes. After transferring the contents of the feeding funnel to the contents of the flask, stir the mixture for 5 minutes. Then apply heat to the contents of the flask using a heating mantle controlled by a J-KEM controller set at 55°C. Heat the contents of the flask to 55°C and maintain this temperature for 90 minutes. Then cool the contents of the flask to room temperature while maintaining positive nitrogen pressure in the flask. When the contents of the flask reached room temperature, acetic acid (2.50 g) was added dropwise to the contents of the flask via a syringe, and the contents were stirred for 5 minutes. The polymer was recovered by non-solvent precipitation of the aqueous solution with excess methanol. The precipitated cationic dextran polymer was then recovered by filtration through a Buchner funnel and vacuum dried overnight at 50°C. The product, a branched cationic dextran polymer, was a grayish-white solid (24.3 g) with a volatile content of 3.65% and an ash content of 0.37% (based on sodium chloride). 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 matter and ash content), which corresponds to a trimethylammonium substitution degree CS of 0.19. The weight-average molecular weight M of the product cationic dextran polymer was... W It is 1,820,000 Daltons.

[0064] Fragrance deposition during washing

[0065] Fragrance deposition during washing of cotton fabrics with the fragrance-containing fabric care compositions was evaluated for each of the compositions in Comparative Examples CF1-CF3 and Example F1, with five replicate tests performed for each fragrance-containing fabric care composition. Cotton fabrics were washed with the fragrance-containing fabric care compositions using the following procedure. One cotton sheet was cut for each experiment, and the initial dry weight was recorded. 20 mL of 200 ppm (3:1 calcium:magnesium by weight) water was added to a 25 mL vial. A magnetic stir bar was added to the vial, followed by 0.4 g of the fragrance-containing fabric care composition. The vial was stirred at 1,000 rpm on a 15-position stir plate. One cotton sheet was added to the vial, and the wash was performed for 15 minutes. The solution was poured out, and 200 mL of 200 ppm water was added, followed by rinsing for 3 minutes. As described in Table 5, the cotton sheet was removed and placed on a drying rack for 40 or 60 minutes to dry. The dried sheet was added to a 20 mL gas chromatograph (CG) headspace vial and immediately sealed with a rolled edge. Record the final quality.

[0066] Gas chromatography / mass spectrometry analysis

[0067] Using an Agilent 7890B GC equipped with a 5977MS detector and an Agilent 7697A headspace sampler with the settings shown in Tables 3 and 4, the mass of fragrance deposited on fabrics using the fragrance-containing fabric care compositions of Comparative Examples CF1-CF3 and Example F1 was quantified by gas chromatography-mass spectrometry (GC-MS). Standards for four fragrances (benzyl alcohol, citronellol, linalool, and limonene) were prepared by weight in hexane (concentration range 10-1000 ppm, wt / wt). Standards for headspace GC-MS analysis were prepared by weighing 10-15 mg of each calibration mixture into 22 mL headspace vials and sealing them with Teflon-lined septa. Headspace analysis of the standards was performed in total evaporation mode to eliminate matrix effects that may occur in static headspace sampling. In this mode, small sample volumes are used, and the headspace vial temperature is set high enough to allow complete evaporation of the volatiles of interest. Calibration curves were prepared for each individual fragrance using at least five standard concentrations of the compound. The amount of each fragrance in each sample was then determined from the calibration curves using a linear least squares equation. The amount of fragrance detected in each fabric was then converted to ng of fragrance. The average mass (in ng) of fragrance components detected on the surface of the test fabric in five repeated tests is reported in Table 5.

[0074] Viscosity comparison

[0075] The viscosities of the fragrance-containing fabric care compositions of Comparative Examples CF1, CF3, and Example F1 were determined using an Anton Parr dynamic mechanical analyzer (model MCR 702 MultiDrive) in a cup-pendulum configuration. The cup diameter was 28.917 mm, and the pendulum diameter was 26.656 mm. Twenty-five grams of the fragrance-containing fabric care composition were placed in the cup. Measurements were taken at a constant temperature of 25°C. A linear shear rate curve was applied to the samples. The shear rate ranged from 1 to 100 s over a period of 550 seconds. -1 The data reported in Table 6 are from the 20s. -1Viscosity measured at the shear rate.
