Definitions

  • the present invention relates generally to compositions for use in machine dishwashers to facilitate the cleaning of dishes and the like. More particularly, it relates to compositions which reduce water spot formation on articles cleaned in machine dishwashers.
  • Machine dishwashers are widely used to clean soiled dishes, cooking utensils and other containers for serving and preparing food, such as, for example, plates cups, glasses, silverware, pots and pans, generically referred to as "dishes". While the construction and composition of these items vary widely, most usually have glossy, solid surfaces on which the presence of dried water spots is readily noticeable. These dried water spots are aesthetically unappealing and thus methods and compositions for reducing their number and size are of great concern to the detergent industry as well as to the consumer.
  • Typical machine dishwashers operate by subjecting food-soiled dishes and the like to alternating wash and rinse cycles inside a closed washing chamber. Spray nozzles inside the chamber direct powerful streams of hot wash liquor and rinse water onto the soiled dish surfaces. A considerable amount of food residue is thereby removed by the force exerted by these pressurized water streams. There is, however, a substantial amount of food residue which resists dislodgement by the water jets. It is known that by adding certain detergent compositions to the wash water, a much greater quantity of food-soil can be removed from soiled article surfaces during the washing cycle.
  • surfactants not only help remove food residue by emulsification, they also provide cleaning power through wetting, foaming, dispersing and penetrating actions.
  • Automatic dishwashing detergents also contain detergent builders such as, for example, complex phosphates, carbonates, sulphates and silicates which compliment the detersive action of surfactants. for example, by sequestering certain metallic ions which are present in most water sources, phosphates reduce hard water film formation caused by the deposition of metallic precipitates.
  • alkalinity builders provide alkaline cleaning power which is particularly important in automatic dishwashing compositions since, by its very nature, automatic dishwashing does not provide the mechanical action of hand dishwashing. Since physical contact with the wash liquor by the consumer does not occur when dishes are cleaned in a machine dishwasher, alkalinity builders are especially suitable for use in automatic dishwashing detergents.
  • Bleaches can also be used in connection with these other dishwashing detergent composition components to remove food residue by breaking down the food residue to simpler components.
  • the cleaning action of bleaches differs somewhat from most other dishwashing composition components in that bleaches clean by breaking chemical bonds within molecules rather than the physical bonds which exist between molecules.
  • bleaches are reducing agents
  • typical bleaches employed in dishwashing compositions are oxidizing agents. Basically, oxidizing bleaches cause the oxidation of chemical bonds, thereby reducing large molecules to smaller units. The smaller units can then be more easily removed during the dishwashing process.
  • the most widely used oxidizing bleaches, particularly in dishwashing compositions are dry chlorine bleaches.
  • hypochlorite generators such as, for example, sodium dichloroisocyanurate and chlorinated trisodium phosphate.
  • Chlorine bleaches are strong oxidizing agents but their usefulness is limited by their tendency to cause unwanted oxidation of other wash compound components and by their brief shelf life. Chlorine bleaches are such strong oxidizing agents that great care must be taken to ensure that the other components with which they are mixed are not adversely affected during storage and, moreover, during use. Due to these and other drawbacks inherent in the use of chlorine bleaches in dishwashing compositions, many formulators have instead proposed that oxygen bleaches be used as the principal oxidizing agent in dishwashing compositions.
  • Oxygen bleaches not only possess greater potential compatibility with other dishwashing composition components, they exhibit much greater stability during storage. While the most frequent oxygen bleach proposed for use is sodium perborate, the use of many inorganic peroxides, such as, for example, sodium percarbonate, potassium monopersulphate, and hydrogen peroxide has also been proposed.
  • proteolytic enzymes are capable of reducing the amount of particulate protein soil on dish surfaces during machine dishwashing operations.
  • proteases are effective in the removal of protein food soil by virtue of their ability to catalyze the hydrolysis of protein peptide linkages. Proteins, which are very high molecular weight compounds, are thereby converted into smaller peptide units which are more easily removed from article surfaces during the cleaning process.
  • Automatic dishwashing compositions have thus been formulated in the past which contain proteases such as that disclosed in US-A- 4 101 457.
  • Proteolytic enzymes are themselves proteinaceous molecules. Therefore, it has been generally held that when these enzymes are brought in contact with bleach, the enzymes are oxidized into simpler components, thus losing their ability to catalyze the breakdown of peptide bonds. That is, it has been thought that unless the proteolytic enzymes are protected somehow from oxidation by the bleach, they are unable to perform their catalytic function.
  • This widely-held belief has resulted in numerous attempts to isolate bleaches from proteases both during storage of compositions containing both of these ingredients as well as during the wash cycle. For example, attempts have been made to microencapsulate bleach to delay its oxidizing action in the wash liquor until after the proteolytic enzymes have had an opportunity to catalytically break down protein soils.
