84526-AR-NP LAUNDRY DETERGENT FORMULATION The present invention relates to a laundry detergent formulation. In particular, the present invention relates to a laundry detergent formulation incorporating a detergent component, wherein the detergent component comprises a detergent surfactant; optionally, a crosslinked cellulose ether; and a drain aid component, wherein the drain aid component comprises: 40 to 99% by weight of an organopolysiloxane comprising: 0 to 60% by moles of units of Formula I R X1SiO(4-X) / 2 (I) at 100 mol % of Formula II units R y1R z2SiO(4-yz ) / 2 (II) wherein x is selected from the group consisting of 0, 1, 2 and 3; wherein y is selected from the group consisting of 0, 1 and 2; wherein z is selected from the group consisting of 1 and 2; with the proviso that y + z is 1, 2 or 3; wherein R1 is a hydrogen, a hydroxy group or a group having 1-8 carbon atoms; wherein R2 is a -AcR3 group; wherein A is a divalent linking group; wherein c is 0 or 1; wherein R3 is a group having 9-35 carbon atoms; 1 to 30% by weight of an organosilicon resin; 0 to 30% by weight of a hydrophobic additive; provided that when the laundry detergent formulation contains >0.02% by weight of the drain aid component, the laundry detergent formulation 2006555 of 53 84526-AR-NP laundry shall also contain at least 0.1% by weight of crosslinked cellulose ether containing 0.1 to 0.6% by weight of polyether groups. There is growing pressure from governments and consumers to improve the energy efficiency of everyday activities such as laundry. A historical approach to improving laundry energy efficiency has been the development of laundry detergent formulations that offer cleaning at reduced wash temperatures. However, consumers increasingly exhibit a tendency to increase wash temperatures, perceiving that higher wash temperatures will better kill contaminating microbes present in the laundry. Consequently, there remains a desire to find alternative ways to reduce the energy required for laundry. One method to further improve the energy efficiency of the laundry process would be to reduce the energy required to dry laundry after washing. One way to achieve this goal includes improved wastewater removal from the laundry during the spin cycle, which leaves fabrics drier when removed from the washer. Drier fabrics outside the washer would produce less water that requires removal during the drying process. In addition, improved wastewater removal from fabrics can be anticipated to reduce malodor, particularly when drying is performed under humid conditions (e.g., line drying during the wet season). Another approach to further improve the energy efficiency of the laundry process is to provide the detergent formulation in condensed form, preferably in a solid format which helps reduce transportation costs associated with certain liquid formats. For example, tablet detergent formulations provide several advantages over conventional formulations. 2006555 of 53 84526-AR-NP formulations provided in liquid form; for example, ease of dosing, storage, transportation, and handling. Tablet-shaped detergent formulations are typically prepared by premixing the detergent formulation ingredients and then forming the premixed ingredients into tablets using suitable equipment, e.g., a tablet press. Detergent tablets are typically formed using compression of the components to provide tablets that are sufficiently robust to facilitate shipping and handling without damage. In addition to robustness, detergent tablets must dissolve quickly enough so that the detergent ingredients can be released into the wash water as soon as possible at the beginning of the wash cycle. A dichotomy persists in conventional formulations. Higher compression forces used in the preparation of detergent tablets generally correlate with improved robustness. Meanwhile, lower compression forces used in the preparation of detergent tablets generally correlate with improved (faster) dissolution in wash water. This dichotomy is compounded by the fact that conventional detergent tablet formulations tend to exhibit relatively poor long-term storage stability; this has historically been compensated for by using a higher compression specification during manufacturing. A detergent tablet composition is described in Whitaker et al., U.S. Patent No. 6,974,789. Whitaker et al. describe a detergent tablet for use in a washing machine, the tablet having two or more phases, at least one of which comprises one or more of the following: a) a polymeric disintegrant having a particle size distribution such that at least 90% 2006555 of 53 84526-AR-NP by weight thereof has a particle size of less than about 0.3 mm and at least 30% by weight thereof has a particle size of less than about 0.2 mm; or b) a water-soluble hydrated salt having a solubility in distilled water of at least about 25 g / 100 g at 25 ° C; wherein said salt is selected from hydrates of sodium acetate, sodium metaborate, sodium orthophosphate, sodium dihydrogen phosphate, disodium hydrogen phosphate, sodium potassium tartrate, potassium aluminum sulfate, calcium bromide, calcium nitrate, sodium citrate, potassium citrate, and mixtures thereof; and wherein the detergent tablet comprises: i) a first phase in the form of a shaped body having at least one mold therein, the shaped body being compressed under a pressure of at least 250 kg / cm2;and ii) a second phase is in the form of a compressed particulate solid fixed within the mold, the compressed particulate solid being compressed to a pressure of less than about 350 kg / cm2; Therefore, there remains a significant need for new laundry detergent formulations that facilitate a reduction in the energy demand associated with laundry washing. In particular, there remains a need for new laundry detergent formulations that improve the removal of residual water from fabrics during the rinse cycle and / or reduce the transportation costs associated with distributing laundry detergent formulations to consumers.

Caustic soda (NaOH, 50% by weight aqueous concentration, 1.9 mol NaOH / mol AGU) was added to the autoclave in 3 portions over 2 minutes at a temperature of 40 °C. The reaction mixture was held at 40 °C for 30 minutes. Then, ethylene oxide (0.45 mol / mol AGU) was added and the reaction mixture was held for 10 minutes at 40 °C. The crosslinker (EPILOX™ M985 crosslinker; 0.0025 mol / mol AGU) was dissolved in 20 ml of isopropanol and added to the autoclave contents in six increments at 30-s intervals. The autoclave contents were then heated to 80 °C for 40 minutes.At 80 °C, a water-soluble monovalent copper ligand (MCL 2; 1.3 mol / mol AGU) was rapidly injected into the autoclave. NaOH (0.67 mol / mol AGU) was then added in 7 portions over 30 minutes, followed by a 70-minute cooking time at 80 °C. After this, the cross-linked cellulose ether product was washed in hot water (>95 °C), neutralized with formic acid, granulated, dried, and ground. 2006555 of 53 84526-AR-NP Comparative Example C6 and Examples 12-13: Detergent Tablet Detergent tablets were prepared in Comparative Example C6 and Examples 12-13 having the composition set forth in Table 8.

Each laundry load comprised 6 pillowcases, 5 bath towels, and 1 bed sheet. Each load was pre-washed (3 cycles) prior to testing.The stained fabrics (one with eleven stains — tallow with carbon black on cotton; tallow with carbon black on polyester / cotton blend, grass / mud on polyester / cotton blend, dirty motor oil, tomato puree, chocolate drink on cotton, standard clay on cotton, red pottery clay on cotton, dried ink on cotton, spaghetti sauce and lard) (one with three stains — grass, balsamic salad dressing and potato starch) would be sewn into one monitor placed in the laundry load. Both stained monitors were line dried overnight. 2006555 of 53 84526-AR-NP The spots were measured with a MACH 5+ instrument (L, a and b).
