The reaction involves the endohydrolysis of 1,4-β-D-glycosidic bonds in xyloglucan. For the purposes of the present invention, AZCL-xyloglucan (from Megazyme) is used as a reaction substrate to determine xyloglucanase activity. The assay can be carried out in several ways, for example, as described in Example 2 of WO2023 / 165507 or as described in WO 01 / 62903. The xyloglucanase activity (XyloU) of one unit is defined by the assay method described in WO 01 / 62903, page 60, lines 3-17.

[0101] The detergent composition may be prepared using any suitable method known to the skilled person. Typically, the ingredients are blended together in any suitable order. Preferably, the detersive surfactant is added as part of a concentrated premix to which the other optional ingredients are added. Preferably, the solvent is added last, or if an external structurant is added, the solvent is added immediately before the external structurant, in which case the external structurant is added as the last ingredient.

[0102] Methods of washing fabrics :

[0103] The detergent composition of the present invention can be used for washing fabrics. In such methods, the laundry detergent composition is diluted to provide a wash liquor having a total surfactant concentration of greater than 100 ppm, preferably 200 ppm to 2,000 ppm, more preferably 300 ppm to 1000 ppm. The fabric is then washed in the wash liquor, and preferably rinsed.

[0104] method :

[0105] A) pH measurement:

[0106] The pH is measured at 25° C. using a Santarius PT-10P pH meter calibrated according to the instructions with a gel filled probe such as the Toledo probe, part number 52 000 100. The pH is measured at a 10% dilution in deionized water (ie, 1 part laundry detergent composition and 9 parts deionized water).

[0107] B) Method for measuring viscosity:

[0108] The viscosity was measured using an AR 2000 rheometer from TA instruments using a cone-plate geometry with a 40 mm diameter and a 1° angle. The viscosity at different shear rates was measured via a logarithmic shear rate sweep from 0.1 s-1 to 1200 s-1 over a 3 minute period at 20°C. The low shear viscosity was measured at a continuous shear rate of 0.05 s-1.

[0109] Example

[0110] Dry fabric odor headspace was measured for detergent compositions i) comprising a branched surfactant and no xyloglucanase, ii) comprising a xyloglucanase and no branched surfactant; and iii) comprising a combination of a branched surfactant and a xyloglucanase. A synergistic effect was observed in the case of the detergent composition comprising a combination of a branched surfactant and a xyloglucanase.

[0111] Fabric odor headspace analysis

[0112] The method involves using an oscillating detergent to simulate fabric washing in a washing machine. Terry fabrics were ordered from Calderon (Indianapolis, IN, USA). The fabrics were stripped using 2 wash and rinse cycles (using 48 g AATCC detergent at 140°F and soft water), and 2 wash and rinse cycles (no product at 140°F soft water). 3 detergent / fabric enhancer cycles were used using 85 g of unscented detergent and 48.5 g of unscented liquid fabric enhancer to produce preconditioned fabrics. Each cycle was run at 90°F wash / 60°F rinse with 7 gpg water.

[0113] The wash test consisted of four internal and three external replicates for each treatment AJ (Table 2) described below. Each wash test contained a ratio of 18.93 L of water to 40.5 g of liquid detergent test composition, the fabric was tested at 25°C and 7 US gpg, agitated for 12 minutes, rinsed for 3 minutes in 25°C water at 7 US gpg, and spun dry. After rinsing, the fabric was dried at 145F for 30 minutes. The fabric was exposed to 73F and 50% humidity for 4 hours before analysis. GCMS headspace analysis was performed on each fabric sample using the following method.

[0114] Fabric headspace analysis was performed using solid phase microextraction gas chromatography mass spectrometry (SPME GC-MS) as described below. Generally, greater perfume intensity (as measured by headspace analysis) correlates to higher perfume concentrations on the fabric.

[0115] The headspace analysis was performed on four treated fabrics from three different wash cycles, for a total of twelve fabrics. Approximately eight 1 cm points of the test fabric were placed in a 20 mL headspace sample vial (#24694, purchased from Restek, Bellefonte, PA), and the vial was capped (#093640-094-00, purchased from Gerstel, Linthicum, MD). The dry fabrics were equilibrated in a constant temperature and humidity chamber at 21°C and 50% RH for 4 hours before capping.

[0116] The sample vials were then loaded onto a Gerstel MPS2 autosampler (Gerstel Inc., Linthicum, MD, USA). Before headspace analysis, each sample was preconditioned in the machine at 65°C for 10 minutes. The headspace was extracted onto an Agilent 7890B / 5977A GC-MS system (Agilent Technologies, Santa Clara, Calif, USA) equipped with a Supelco 50 / 30 micron DVB / CAR / PDMS 23Ga solid phase microextraction fiber (Supelco Inc., Bellefonte, PA, USA). GC analysis was performed on a nonpolar capillary column (DB-5MS UI, 30 m nominal diameter, 0.25 mm nominal diameter, 25 μm thickness), and the headspace components (i.e., perfume raw materials) were monitored by mass spectrometry (EI, 70 eV detector). The headspace intensity was calculated using a single-point calibration of perfume raw materials. The total headspace concentration for each vial was calculated from the sum of the concentrations of each fragrance raw material tested, and the headspaces of the twelve treated fabrics were averaged.The improvement in headspace can be determined relative to a reference treatment.

[0117] The results in Table 1 demonstrate the dry fabric odor headspace advantage when combining Whitezyme 2.0 (WZ) and branched-chain alkyl sulfates compared to the expected additional benefit of using Whitezyme 2.0 or branched-chain alkyl sulfates independently.
