Definitions
- the invention relates to detergent compositions containing amphoteric polymers to control the deposition of lime soap, particularly machine dishwashing compositions containing lipolytic enzymes.
- a critical criteria for an effective machine dishwashing composition is the appearance of both the washed glassware and plastic articles to the consumer. Spotting and filming of such tableware, when washed with commercial products, generally results from mineral deposition during the evaporation of undrained wash solution in the drying step.
- the deposited minerals are from many sources, including salts of ingredients in the product formulations, calcium carbonate from temporary water hardness, and suspended soil.
- a prior art solution to the removal of these white mineral spots has been the addition of a rinse aid composition to the rinsing water of the machine cycle. Although the visual appearance of the washed tableware is improved, some spotting, but especially mineral film formation has still been observed even with the use of this additional product. Moreover, use of a rinse aid is inconvenient to the consumer.
- hydrophobic soil fragments that are present on washed tableware are believed to be triglyceride and fatty ester soil. Consequently, machine dishwashing and rinse aid compositions incorporating lipolytic enzymes which assist in breaking down these soils have been described in EP-A-346,136 and EP-A-271,155. Although lipolytic enzymes can reduce the formation of mineral spots due to hydrophobic soil fragments, the enzymes can also cause a different type of white deposits to build up on hydrophobic surfaces such as plastics.
- Prior art solutions to these problems include formulations of machine dishwashing compositions incorporating certain lime soap dispersants with lipolytic enzymes as described in WO-94/07984 and WO-94/07985 (Proctor & Gamble). Tableware washed with compositions containing lipases and these lime soap dispersants have been observed to have low lime soap film scores (i.e. little to no filming is observed). However, a large number of white mineral spots on the washed articles have been observed. It is thus believed that the lime soap dispersants described in these publications actually inhibit the action of the lipase.
- Hydrophobically modified copolymers of especially acrylic acid, have been described in copending Gordon et al.; U.S. Serial No. 08/457,690 for incorporation in machine dishwashing compositions. Calcium soap deposition is reduced by the presence of these polymers.
- US-A-4,891,149 describes polymeric lime soap dispersants which consist of copolymers and water soluble salts of copolymers of acrylic acid, methacrylic acid and mixtures thereof and acrylamide, alkyl or alkylol substituted acrylamide, or mixture of said acrylamides.

- Silica, silica gel, and aluminosilicate may also be used as thickeners.
- Salts of polyacrylic acid (of molecular weight of from about 300,000 up to 6 million and higher), including polymers which are cross-linked may also be used alone or in combination with other thickeners.
- clay thickeners for machine dishwashing compositions is disclosed for example in US-A-4,431,559; US-A-4,511,487; US-A-4,740,327; US-A-4,752,409.
- Commercially available synthetic smectite clays include Laponite supplied by Laporte Industries.
- Commercially available bentonite clays include Korthix H and VWH ex Combustion Engineering, Inc.; Polargel T ex American Colloid Co.; and Gelwhite clays (particularly Gelwhite GP and H) ex English China Clay Co.
- Polargel T is preferred as imparting a more intense white appearance to the composition than other clays.
- the amount of clay thickener employed in the compositions is from 0.1 to about 10%, preferably 0.5 to 5%.
- Use of salts of polymeric carboxylic acids is disclosed for example in GB-A-2,164,350, US-A-4,859,358 and US-A-4,836,948.
- a chlorine-resistant polymeric thickener is particularly useful for liquid formulations with a "gel" appearance and rheology, particularly if a clear gel is desired.
- US-A-4,260,528 discloses natural gums and resins for use in clear machine dishwashing detergents, which are not chlorine stable.
- Acrylic acid polymers that are cross-linked manufactured by, for example, B.F. Goodrich and sold under the trade name "Carbopol” have been found to be effective for production of clear gels, and Carbopol 940, 617 and 627, having a molecular weight of about 4,000,000 are particularly preferred for maintaining high viscosity with excellent chlorine stability over extended periods.
- Further suitable chlorine-resistant polymeric thickeners are described in US-A-4,867,896 incorporated by reference herein.
- the amount of thickener employed in the compositions is from 0 to 5%, preferably 0.5-3%.
- Stabilizers and/or co-structurants such as long-chain calcium and sodium soaps and C 12 to C 18 sulfates are detailed in US-A- 3,956,158 and US-A-4,271,030 and the use of other metal salts of long-chain soaps is detailed in US-A-4,752,409.
- Other co-structurants include Laponite and metal oxides and their salts as described in US-A-4,933,101, herein incorporated by reference.
- the amount of stabilizer which may be used in the liquid cleaning compositions is from about 0.01 to about 5% by weight of the composition, preferably 0.01-2%. Such stabilizers are optional in gel formulations.
- Co-structurants which are found especially suitable for gels include trivalent metal ions at 0.01-4% of the compositions, Laponite and/or water-soluble structuring chelants at 0.01-5%. These co-structurants are more fully described in the US-A-5,141,664, hereby incorporated by reference.
- the formulations of the cleaning composition comprising surfactant may further include a defoamer.
- Suitable defoamers include mono-and distearyl acid phosphate, silicone oil and mineral oil. Even if the cleaning composition has only defoaming surfactant, the defoamer assists to minimize foam which food soils can generate.
- compositions may include 0.02 to 2% by weight of defoamer, or preferably 0.05-1.0%.
- Preferred antifoam systems are described in Angevaare et al.; US S/N 08/539,923, herein incorporated by reference.
- lime soap dispersant properties of amphoteric polymers within the scope of the invention was compared to that of lime soap dispersants known in the prior art as described below.
- the polymers were evaluated for their lime soap dispersing power value (LSDP), which is a conventional measurement of the effectiveness of a material for dispersing lime soap.
- the lime soap dispersing power value (LSDP) is defined as the (weight ratio of dispersant to sodium oleate X 100) based on the amount of dispersant required to disperse lime soap curd formed by 0.025g sodium oleate and 30mls of water of 333 ppm. CaCO 3 equivalent hardness. According to the test, a low LSDP value is an indication of an effective lime soap dispersant. A detailed description of the test is found in an article by H.C. Borghetty and C.A. Bergman, J. Am. Oil Chem.
- amphoteric polymers within the scope of the invention are extremely effective lime soap dispersants in comparison to similar polymers outside the scope of the invention and in comparison to the preferred lime soap dispersants claimed in WO 94/07984 and WO 94/07985
- a base machine dishwashing detergent composition was prepared as described in Table 2 below.
- STPP 51.0 Sodium silicate (PQ Britesil H20) 30.0 Sodium Percarbonate 9.0 TAED (tetraacetylethylenediamine) 3.6 Protease (Novo Savinase 6T) 3.0 Amylase (Novo Termamyl 60T) 1.8 Lipase (Novo Lipolase 100T) 0.2 Nonionic (BASF Plurafac LF403) 1.4 Lime soap dispersants were incorporated into the described base at a level of 5% by wt. in addition to the above composition.
- the number of spots on each item was counted, with the average number of spots per article reported.
- the number of spots on the glass tumblers gives an indication of the effectiveness of the lipase.
- the lowest number of spots corresponds to the most effective lipase action.
- composition 2 addition of lipase to the base formulation results in a significant reduction in the number of spots on the glass tumblers (Composition 2). This is indicative of lipase functioning in the system.
- Filming on polyethylene items is very high, due to lime soap deposition.
- Addition of an amphoteric polymer within the scope of the invention (Composition 3) significantly reduces the film score on polyethylene items, while the excellent glassware appearance produced by lipase is retained, as seen by the low spotting scores on the glass tumblers.
- the materials described in WO94/07984 and WO/07985 reduce lime soap deposition, they also greatly reduce
- amphoteric polymers to reduce lime soap deposition without inhibiting the antispotting benefit provided by lipase was further demonstrated as follows:
- This example further illustrates the effectiveness of amphoteric polymers within the scope of the invention in improving glass and plasticware appearance by inhibiting the deposition of lime soap while maintaining the antispotting benefit provided by lipase.
