Definitions

  • This invention relates to low foaming detergent compositions for use in automatic dishwashers.
  • laundry detergents for use in automatic dishwashing machines of the type used in homes and in commercial facilities differ from laundry detergents.
  • Laundry detergents usually contain substantial amounts of anionic surface active agents to increase sudsing (foaming) since the fabrics to be washed are immersed in the detergent solution with soil removal being dependent upon emulsification, peptization and mechanical action by tumbling or by means of an agitator.
  • Nitriloacetate salts such as trisodium nitrilotriacetate monohydrate and disodium monohydrogen nitrilotriacetate monohydrate appear to be satisfactory for use in laundry detergents and in non-chlorinated dishwashing detergents.
  • nitriloacetate salts cause rapid degradation of the chlorine releasing agents frequently employed in detergents thus reducing the amount of available chlorine.
  • nitriloacetate salts would be suspected of contributing to nitrogen pollution of rivers and lakes.
  • Dishwashing detergents normally employ a large proportion of inorganic alkaline detergent salts (builders) such as carbonates, bicarbonates, silicates, borates, perborates and phosphates.
  • inorganic salts as sodium chloride and sodium sulfate are also frequently employed as fillers to increase the bulk of the composition.
  • the phosphate salts in addition to providing alkalinity for detergency, serve as water softening agents by chelating or sequestering magnesium and calcium ions present in hard wash water.
  • dishwashing detergents As chelating agents, low molecular weight linear polymers of maleic anhydride with vinylacetate. Structurally these polymeric materials can be represented as follows:
  • M is hydrogen, ammonium or an alkali metal and n is an integer such that the product has a relative viscosity of from 1.0 to 10.0 when determined on a 4 percent aqueous solution at 25 C.
  • the relative viscosity of the said maleic anhydride polymers be relatively low. Since there are certain inherent viscosity differences depending upon the particular polymer product, the preferred relative viscosities will vary; the limiting criteria being that the polymers be susceptible to handling and blending with the other components of the new detergent as well as affording satisfactory performance. For example, with a Vinylacetatemaleic anhydride polymer it is preferred that the relative viscosity range be from 1.0 to 10.0 when determined on a 4 percent aqueous solution at 25 C. (acid form).
  • Vinylacetate-maleic anhydride copolymers are prepared by charging 98.10 grams (1.0 mole) maleic anhydride, 86.06 grams (1.0 mole) vinylacetate, 2.42 grams (0.01 mole benzoyl peroxide and 1,000 milliliters of an organic solvent, such as benzene, toluene, xylene or mixtures thereof, into a suitable reaction vessel.
  • the reaction vessel if not sealed, should be equipped with a reflux condenser, an agitator, a means of heating and a thermometer or other means of determining temperature.
  • the mixture is heated to C. at which time the copolymer begins to form and depending on the solvent system may require cooling.
  • the temperature is maintained at 80-85 C. for l to 5 hours, preferably 2 to 2-V2 hours.
  • the product can be isolated as the anhydride at this stage by filtering the insoluble copolymer. If the acid form of the copolymer is desired, grams of water can be added and the mixture stirred and heated for an additional 30 minutes. The acid form of the copolymer will then precipitate and can be recovered from the solvent. If, for example, the sodium salt form is desired, the addition of sodium hydroxide can be made at the time water is added.
  • the copolymer thus obtained has a relative viscosity at 1.0 to 10.0 (depending on solvent used for the reaction). The viscosity is determined on a 4 percent aqueous solution.

  • the performance of chelating agents in dishwashing detergents is best evaluated by testing the detergents under dishwashing conditions.

The dishes are allowed to air-dry. This completes a dishwashing cycle. After completion of five such cycles, the glasses are evaluated for filming and spotting. The transparent nature of the glasses makes them more amenable to grading than opaque dishware and furthermore a filmed glass is more conspicuous than a filmed dish.
