  • a minimum of 20 panelists are employed to obtain statistically significant data points. Panelists thoroughly wash and dry their hands (or use alcohol based hand sanitizer) immediately prior to panel testing, without using any lotion or other moisturizers.
  • the GelWhite GP provided the most preferred softening between the various clay compounds employed as the softening boosters.
  • TABLE 29 Sample Product Grams Booster Grams of Booster A L2000/Bleach/ Clearly Soft 90/70/52 Clearly Soft as booster at 5% actives 26 B L2000/Bleach/ Clearly Soft 90/70/52 Gelwhite GP (10%) clay added at 5% actives before CS dosing 26 C L2000/Bleach/ Clearly Soft 90/70/52 Barlox 16S (6%) added at 5% actives 43.3
  • the addition of the softening booster (Gelwhite GP with Clearly Soft) provided preferred softening.
  • the HunterLab Color Quest Spectrophotometer was conducted after the 6 th cycle employing the softening booster compositions according to the invention were added
  • Reading Towels on the Hunterlab The purpose is to measure reflectance oftowels.
  • the HunterLab Colorquest XE spectrophotometer is employed. As shown in Table 44, the data generated appear as L*, a*, b*, WI 313, YI 313, and Z %.
  • WI 313--Whiteness Index This an index of overall whiteness that also takes the "b" number into account. The higher the number, the whiter the sample.
  • YI 313--Yellowness Index This an index of overall yellowness that also takes the "b" number into account. The higher the number, the yellower the sample.
  • the softening boosters provide desired softness without imparting any detrimental yellowing of the treated linens.
  • Wicking testing was conducted to assess absorption of water from evaluated towels treated with softening boosters.
  • the absorbency of towels from the softness panel in Example 2 were evaluated to determine how different fabric treatments affect the wicking/absorption volume of a fabric.
  • test swatches (approximately 4"x7") are cut.
  • the swatches are marked with a line 10 mm from the bottom and placed in the colored dye solution (water soluble dye of any concentration) using a wicking apparatus.
  • One test swatch is suspended from the top of the wicking apparatus using a large paper binder clamp.
  • the test swatch is lowered into the colored dye solution up to the scored line and let to sit undisturbed for 6 minutes. Thereafter, the test swatch is raised from the dye solution and the highest point reached by the dye solution is marked by a dot (using a permanent marker). The distance from the 10 mm line to the dot (in millimeters) is measured and recorded.
  • Example 3 Additional wicking testing was conducted after the evaluation of Example 3 using the conditions set forth in Table 46.
  • the Conditions C and D each refer, respectively, to the booster added in an additional 6 th cycle where they towels were either not dried or dried prior to the 6 th cycle. All towels were dried after completing the cycles in the washer to build up the appropriate amount of chemistry (with or without softening booster).
  • the test conditions where the liquid traveled farthest were the control an Gelwhite GP added during the 5 th cycle.
  • the two conditions where an additional 6 th cycle was added to provide Clearly Soft and Gelwhite GP demonstrated considerably lower wicking ability.
  • only the condition D with a drying step before the 6 th cycle provided wicking below the threshold level of 20 mm (conventional wicking standard).
  • the softness evaluation was conducted as shown in Table 48.
  • a softness panel (varying number of participates with average score) completed one-on-one sensory comparisons of evalulated towels treated with the fabric treatment composition according to the invention.
  • the towel with the preferred softness based on the touch (sensory) evaluation of the panelist was ranked numerically based on a standard towel as a comparison (tanked 1 to 5).
  • a high panel testing number correlates to softer panel evaluation results.
  • the panel results show that the 2x/2x combination was equally soft as the 1x/1x combination.
  • the highest softness rating was achieved for the 1x/2x combination (1x softening booster composition / 2x fabric softening composition)
  • a limitation of the testing was the lack of consistency among the fill towels (not equal in treatment or age which may have introduced variability into the test results).
  • the boosting agent provided significant improvement in softening.
  • the present invention refers to the following aspects:
