  • biodegradability and performance characteristics of the blend are believed to be at least partly attributable to the ordered structure of the compositions in which limited numbers of propylene oxide groups are directly attached to the alcohol followed by the addition of the ethylene oxide groups and capping using an 1,2-epoxyalkane. While maintaining this ordered structure, it is desired to also have low ratios of propylene oxide groups to ethylene oxide groups.

  • Epoxy compounds useful for making the epoxy-capped poly(oxyalkylated) alcohols of the present invention include any 1,2-epoxyalkanes, or mixtures thereof, having a hydrocarbon chain containing an average of about 2 to about 26 carbon atoms, with the proviso that at least one of the surfactants in the blend (namely the component (a) surfactant described above) contain between two and four carbons on this hydrocarbon chain.
  • the 1,2-epoxyalkane has a linear, aliphatic hydrocarbon chain containing an average of from about 8 to about 20 carbon atoms, and more preferably an average of from about 10 to about 16 carbon atoms.

  • novel surfactant compositions of the present invention provide improved surface treatment of the tableware by the rinse water and subsequently reduces spotting and filming.
  • These epoxy-capped poly(oxyalkylated) alcohols can be formulated in powder and liquid detergent products for automatic dishwashers or in hard surface cleaning products, such as bathroom tile, using methods commercially practiced in the detergent industry.
  • These formulations can include, for example, detergent builders, chelating agents, bleaches, anti-wear agents, and combinations thereof, among others.

  • the STPP may be anhydrous or hydrated, including the stable hexahydrate with a degree of hydration of 6 corresponding to about 18% by weight of water or more.
  • Organic builders can also be used including nitrilotriacetic acid and alkali metal salts of tartaric or citric acid.
  • a chelating agent can be any one of a wide range of organic or inorganic sequestering agents, examples including phosphoric acid, amino polycarboxylic acids such as ethylene diamine tetraacetic acid (EDTA) , NTA and DETPA, and polycarboxylic acids such as lactic acid, citric acid, tartaric acid, gluconic acid, glucoheptonic acid, mucic acid, galactonic acid, saccharic acid, fumaric acid, succinic acid, glutaric acid, adipic acid and their alkali metal or ammonium salts.
  • Citric or tartaric acid are preferred chelating acids.
  • the chelating agent if included is present in an amount of up to about 30% and normally lies in the range from about 5% to about 20% by weight.
  • compositions use from about 5% to about 10% by weight of chelating agent in order to minimize any attack by the chelating agent on the glass.

  • the dishwasher formulations may also include anti-wear or anti-corrosion agents such as an alkali metal silicate, preferably sodium silicate, and may be present in a ratio of 0.1 to 3 and preferably 0.2 to 1 mole per mole of alkali in the cleaning composition.

  • the present invention as described herein provides liquid blends useful as nonionic surfactant/rinse aids and characterized by excellent cleaning efficacy and biodegradability. These products are suitable for use in both industrial and institutional and automatic dishwashing applications, since the liquid blends provide an excellent combination of low foaming, excellent rinsing, and efficient removal of high protein soil. These results are particularly surprising since, in general, prior art linear alcohol alkoxylates capped with 1,2-epoxyalkanes which are efficacious with regards to defoaming in high protein soils are either relatively insoluble in water, thus forming cloudy dispersions, or possess relatively poor rinsing properties.
  • the formulation of the product blends with desirable properties in accordance with the present invention was determined based upon statistical experimental design techniques involving individual compositions of a wide range of molecular structure. This insured the potential for providing blends over a reasonable range of cloud points and possessing the desirable properties of excellent machine defoaming, rinsing efficacy, and solution stability.
