Title: Stable unit dose compositions

Description:
FIELD OF INVENTION 
     This invention is in the fields of household and industrial cleaning. More particularly, the invention relates to stable unit dose compositions with enhanced pack rigidity. Such unit dose compositions comprise a liquid composition having at least four non-aqueous solvents, a water, a beneficial composition, and a water-soluble container formed from a water-soluble or water-dispersible film material. 
     BACKGROUND OF THE INVENTION 
     Unit dose detergent products are often found by consumers to be preferable for use in automatic dishwashing and laundry applications. Such unit dose products have several advantages, including convenience of use and dispensing, lower cost per use, and avoiding or minimizing skin contact with potentially irritating cleaning compositions. 
     In unit dose formulations with high solvent content, e.g., over 30% wt of total added solvent on the weight of the entire formulation, it is difficult to maintain pack rigidity in multi-chamber products using polyvinyl alcohol (PVOH) or polyvinyl acetate (PVA) film. With increased solvent content, the weight of the liquid composition in the compartment of multi-chamber product makes it ‘sag’ down, making the unit dose composition appear ‘floppy’. Moreover, such unit dose compositions may suffer from unexpected rupturing. This is due to the weight of one compartment putting undue load pressure on the film causing it to overstretch and rupture which will lead to leakage or breakage. 
     Traditional formulas have included a total of three solvents. The most commonly used solvent system includes water, glycerin, and propylene glycol. Recently, an ionic liquid has also been employed as a solvent. 
     There remains a need in the art for a unit dose composition with high solvent content while maintaining pack integrity such as rigidity and stability. 
     It was surprisingly found that employing a solvent system that employs at least five solvents, e.g., glycol ethers, polyethylene glycols, or diols, stabilizes the unit dose system and enhances rigidity to an acceptable level despite the much higher solvent content. This invention shows the benefit of a structured solvent system with five different solvents and how it improves pack rigidity (i.e. height) by up to 15%, which is extremely significant. Overall benefit to the consumer is a more stable unit dose pack that is less prone to leakage or breakage, and one that is more aesthetically pleasing during handling.

Suitable fatty acid amides include C 8 -C 20  alkanol amides, monoethanolamides, diethanolamides, or isopropanolamides. 
     Suitable anti-redeposition agents are typically polycarboxylate materials.

Unsaturated monomeric acids that can be polymerized to form suitable polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polycarboxylates herein of monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40 wt % of the polymer. 
     Particularly suitable polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerised acrylic acid. The average molecular weight of such polymers in the acid form ranges from about 2,000 to 10,000, from about 4,000 to 7,000, or from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials (e.g., those described in U.S. Pat. No. 3,308,067). In one embodiment, the polycarboxylate is sodium polyacrylate. 
     Acrylic/maleic-based copolymers may also be used as a component of the anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form ranges from about 2,000 to 100,000, from about 5,000 to 75,000, or from about 7,000 to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1:1, or from about 10:1 to 2:1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers are known materials (e.g., those described in EP 193360). Other useful polymers include maleic/acrylic/vinyl alcohol terpolymers (e.g., a terpolymer containing 45/43/10 of acrylic/maleic/vinyl alcohol as described in EP 193360). 
     In addition to its role as a solvent, polyethylene glycol can act as a clay soil removal-anti-redeposition agent. Molecular weight of suitable polyethylene glycol can range from about 1,000 to about 50,000, or about 3,000 to about 10,000. Polyaspartate and polyglutamate dispersing agents may also be used herein. 
     Any polymeric soil release agent known to those skilled in the art can optionally be employed herein as well. Polymeric soil release agents are characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit upon hydrophobic fibers and remain adhered thereto through completion of washing and rinsing cycles and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occurring subsequent to treatment with the soil release agent to be more easily cleaned in later washing procedures. 
     Suitable soil-releasing polymers include, but are not limited to, anionic hydrophobic polysaccharides of the type as disclosed in U.S. Pat. No. 6,764,992. Each of the patent references is incorporated herein by reference in its entirety. 
     Any suitable process known to those skilled in the arts of cleaning, color care, fragrance or softening compositions can be used to make the liquid compositions of the present disclosure. 
     Uses 
     The liquid composition or unit dose composition of the present disclosure can be added to a wash liquor to which laundry is present, or to which laundry will be added. It may be used in combination with other laundry detergent compositions, such as, e.g., fabric softeners or stain removers. It may also be used in an automatic washing machine operation and added directly to the drum or to the dispenser drawer of the machine. 
     The unit dose composition of the present disclosure can be added to a wash liquor to which dishes are present, or to which dishes will be added. It may also be used in an automatic dishwashing machine operation and added directly to the drum or to the dispenser drawer of the machine. 
     In some embodiments, the unit dose composition of the present disclosure is substantially free of efflorescence. Efflorescence is a phenomenon when solvated salts precipitate out, on, or in the film. 
     EXAMPLES 
     The following examples are illustrative and non-limiting of the compositions of the present invention. Suitable modifications and adaptations of the variety of conditions, formulations, and other parameters normally encountered in the field and which are obvious to those skilled in the art in view of this disclosure are within the spirit and scope of the invention. 
     Example 1: Unit Dose Composition 
     As shown in Table 1, unit dose compositions were prepared by incorporating solvents, polymers, enzymes, chelators, fragrances, and other functional materials commonly used in a finished product. 2-methyl-1,3-propanediol (MP Diol), polyethylene glycol 400 (PEG 400), diethylene glycol butyl ether (Butyl Carbitol), and ethylene glycol monobutyl ether (Butyl Cellosolve) were added as the fifth solvent (“inventive” samples B-E). As a comparison, “traditional sample” F contained four solvents, consisting of water, propylene glycol (PG), Glycerin (Gly), and Tris (2-hydroxyethyl) methyl-ammonium methylsulfate (an ionic liquid).

     Example 2: Stability Testing of a Multi-Chamber Pack with Five Solvents 
     The liquid composition prepared according to Table 1 was placed into a multi-chamber pack. The multi-chamber pack has two outer chambers each containing 11 grams of liquid composition according to Table 1 and an empty center chamber that was filled with 2.5 grams of powder material. Pacs were created using two different PVOH water-soluble films: MonoSol film M8312 and MonoSol film M8720. Pacs were placed into temperature controlled environment at 68° F. (20° C.), and observations and analyses were performed over a period of time. Height of the chamber was measured over 48 hours and over 3 months as an indicator of pack rigidity. Height of the chamber was measured by Ames Logic Basic Digital Comparator Model BG1110-1-04, on a column mounted indicator, model 99-0697. Height of the sample was measured by placing pack under digital indicator, after the scale was zeroed. 
     As shown in Table 2, the addition of a fifth solvent, such as, MP Diol, PEG, or glycol ether showed various improvements over comparative samples with no additional fifth solvent added. More specifically, the addition of PEG 400 or butyl carbitol improved pack rigidity (i.e. height) by up to 15% over 48 hours and over 3 months.

     Example 3: Rigidity Test 
     Pacs prepared as shown in Table 1 and Table 2 were placed into a temperature controlled environment at 68° F. (20° C.), and studied over 24 hours. Pack rigidity was graded on a 1 to 5 scale with 5 being most floppy and 1 being most firm. As shown in Table 3, Formulas B-E with the addition of a fifth solvent, such as, MP Diol, PEG 400, butyl barbitol, butyl cellosolve, showed improvement of rigidity over a comparative sample (Formula F).
