The weight average molecular weight of the dextran polymer was 100,000-200,000 Daltons. The addition funnel was charged with a 70% aqueous solution of 2,3-epoxypropyltrimethylammonium chloride (30 g; QUAB® 151 available from SKW QUAB Chemicals) and a 40% aqueous solution of 3-chloro-2-hydroxypropyl-lauryl-dimethylammonium chloride (39.3 g; QUAB® 342 available from SKW QUAB Chemicals). While stirring the contents of the flask, the apparatus was purged with nitrogen to remove any oxygen trapped in the system for 1 hour. The nitrogen flow rate was approximately 1 bubble per second.

[0052] Using a plastic syringe, 25% aqueous sodium hydroxide (11 g) was added to the contents of the flask over a period of several minutes while stirring under nitrogen. The contents of the flask were then allowed to stir under nitrogen for 1 hour. The contents of the addition funnel were then dripped into the contents of the flask over a period of several minutes under nitrogen with continued stirring. After the contents of the addition funnel were transferred to the contents of the flask, the mixture was allowed to stir for 20 minutes. Heat was then applied to the contents of the flask with a heating mantle controlled using a J-KEM controller set at 55° C. The contents of the flask were heated to 55° C. and maintained for 1.5 hours.

[0053] The contents of the flask were then cooled in an ice-water bath while maintaining a positive nitrogen pressure in the flask. When the contents of the flask reached room temperature, glacial acetic acid (1.66 g) was added to the contents of the flask. The contents of the flask were then stirred under nitrogen for 10 minutes. The product solution was used without further purification. The product polymer was characterized by nuclear magnetic resonance (1H NMR) spectroscopy for structural analysis and the degree of substitution of the trimethylammonium moiety, DS, reported in Table 2.

[0061] Synthesis S10: Fragrance A fragrance solution having the composition set forth in Table 3 was prepared.

[0062] [Table 3]

[0063] Comparative Examples CF1-CF6 and Examples F1-F4: Fabric Care Compositions Fabric care compositions having the formulations set forth in Table 4 were prepared in each of Comparative Examples CF1-CF6 and Examples F1-F4 and were prepared by standard laundry formulation preparation procedures. The fabric care compositions were observed for formulation stability and those exhibiting phase separation were identified as not stable. These observations are reported in Table 4.

[0064] [Table 4]

[0065] Fragrance adheres during cleaning Perfume deposition from wash liquors containing the fabric care compositions was evaluated on cotton test swatches (Scientific Services S / D Inc. Cotton 400) in five replicates for each of the compositions of Comparative Examples CF1-CF2 and Examples F1-F3. The cotton test swatches were cut into 0.5 inch diameter cotton disks. The initial dry mass of each cotton disk was measured and recorded. A separate 25 mL vial was provided for each fabric care composition tested. Water (20 mL of 200 ppm (3:1 by weight Ca) was then added to each vial. 2+ :Mg 2+)) was added to each vial. A magnetic stirrer and fabric care composition (0.4 g) were then added to each of the vials. The vials were then placed on a stirring plate set at 1,000 rpm. A cotton disk was then added to each vial and left to stir for 16 minutes. The wash solution was then drained from each vial and then fresh water (20 mL of 200 ppm (3:1 by weight Ca 2+ :Mg 2+ ) was added to each vial with the cotton disk and stir bar. The vials were then placed back on the stir plate set at 1,000 rpm and left to stir for 3 minutes. The cotton disks were then removed from the vials and placed on a drying rack for 60 minutes. Each dried disk was then placed into a separate 20 mL gas chromatography (GC) headspace vial and immediately crimp sealed. The final mass of each cotton disk was then measured and recorded.

[0066] Gas Chromatography / Mass Spectrometry The mass of perfume deposited on fabric using each of the perfumed fabric care compositions of Comparative Examples CF1-CF2 and Examples F1-F3 was quantified by gas chromatography / mass spectrometry (GC-MS) using an Agilent 7890B GC equipped with a 5977 MS detector and an Agilent 7697A headspace sampler with the settings described in Tables 5 and 6. Standards of the four fragrances (benzyl alcohol, citronellol, linalool, and limonene) were prepared by weight in hexane (concentration range 10-1000 ppm, wt / wt). The standards were prepared for headspace GC-MS analysis by weighing 10-15 mg of each calibration mixture into 22 mL headspace vials and capping with Teflon-lined septa. Headspace analysis of the standards was performed in full evaporation mode to eliminate possible matrix effects with static headspace sampling. In this mode, small sample sizes are used and the headspace vial temperature is set high enough to completely evaporate the volatiles of interest. For each individual fragrance, a calibration plot was prepared using at least five standard concentrations for that compound. The mg amount of each fragrance in each sample was then determined using a linear least squares equation from the calibration plot for that compound. The mg amount detected in each fabric piece was then converted to ng of fragrance. The average mass (in ng) of fragrance components detected on the surface of the test fabric for the five replicates is reported in Table 7.

[0070] Prevention of contamination reattachment (predictive) The soil redeposition prevention of the fabric care compositions was evaluated on four types of fabric (cotton interlock, cotton, polyester / cotton blend, cotton terry) under typical wash conditions (ambient wash temperature, water hardness: 200 ppm, 3:1 molar ratio Ca) for each of the compositions of Comparative Example CF2 and Example F1. 2+ :Mg 2+ The fabric is evaluated by washing with Terg-O-tometer using a detergent dosage of 0.5g / L at 100°C (1L / wash) for 60 minutes washing and 3 minutes rinsing. Orange (high iron content) clay slurry (0.63g, Red Art Clay) and dust sebum dispersion (2.5g) are the soil loadings. After washing is complete, the fabric swatches are dried and read with Mach5 color instrument to calculate the Whiteness Index (WI) according to ASTM E313. The results are presented as delta whiteness index (ΔWI E313). The lower the value, the better, indicating that Example F1 has better soil redeposition prevention performance than Comparative Example CF2.
