Embodiment 1

[0196] Example 1: Washing performance of liquid detergent compositions comprising endo-beta-1,3-glucanase

[0197] The wash performance of endo-β-1,3-glucanase to remove cosmetic stains from cotton was determined in the environment of liquid laundry detergent as follows:

[0198] Stains were prepared on 5 cm x 5 cm swatches of knitted cotton supplied by Warwick Equest Ltd (Consett, U.K.). Makeup (Living Nature foundation, Pure Honey 30 mL, product code B0014596QE) was applied with a sponge at four locations on each swatch using a well plate with round holes of 1.2 cm in diameter. The stained samples were hung to dry for 24 hours before use and the images were analyzed prior to testing.

[0199] Stain removal tests were performed using a Tergotometer detergent tester supplied by Copley Scientific Ltd (Nottingham, U.K). Two jars were filled with 400 mL of tap water (6.5 grains per US gallon) heated to 40°C, and 1.04 mL of Ariel's liquid (purchased from Asda Stores Ltd, UK, F...

Embodiment 2

[0207] Example 2: Comparison of the Washing Performance of Endo-β-Glucanases of Liquid Detergent Compositions

[0208] The above procedure was repeated, but using two stain samples, each containing five stains, and the images were analyzed for CIELab values ​​(DigiEye, VeriVide, Leicester, U.K.) prior to testing. The test was repeated using each of the following: 0.4 mg active endo-β-1,3-glucanase (CZ0861, Lot No. 18011 from NZYTech, Lisbon, Portugal); 0.4 mg active endo-β-glucanase 1,3(4)-glucanase (E-LICACT from Clostridium thermocellum, Lot No. 160201b, available from Megazyme, Bray Co. Wicklow, Ireland); and 0.4 mg active endo-β- 1,4-Glucanase (Celluclean 5000L, lot number CEN010785 from Novozymes A / S, Bagsvaerd, Denmark).

[0209] This process was performed four times for each enzyme, alternating treatments between two tanks. This resulted in a total of 40 washed stains per treatment, ie 4 external replicates, each replicate comprising 2 samples of 5 stains. CIELab o...
