Definitions

  • the present invention relates to steel wool and to steel wool scouring pads.
  • Steel wool is widely used as a household scouring agent for the cleansing of soiled cooking utensils, many of which are fabricated of aluminum. In conjunction with this scouring, it is desirable that the surface of the aluminum be left not only clean, but polished as Well. Unfortunately, scouring aluminum with steel wool per se leaves the aluminum surface in a dull and lusterless condition.
  • a process for cleansing and polishing aluminum comprises scouring aluminum with steel wool in the presence of an aqueous medium and a partial ester of phosphoric acid and an aliphatic alcohol.
  • Another aspect of the present invention is a body of steel wool, such as a scouring pad, containing or impregnated with a partial ester of phosphoric acid and an aliphatic alcohol.
  • the instant esters are aliphatic partial esters of phosphoric acid.
  • Suitable aliphatic substitutents are those aliphatic radicals containing at least 4 and preferably from 8 to 20 carbon atoms, and mixtures thereof.
  • the aliphatic radicals of the instant esters may be derived from aliphatic alcohols which are straight or branched chain in nature, they may be either saturated or unsaturated, and they may be connected directly to the phosphoric acid moiety or indirectly, as through an intermediate linkage such as a lower polyhydric alcohol, e.g. glycerine.
  • the phosphoric acid portion of the esters may be orthophosphoric acid as well as polyphosphoric acids, e.g.
  • esters and trimers of orthophosphoric acid corresponding to self-condensation products thereof prepared by elimination of water, e.g. pyrophosphoric acid and tripolyphosphoric acid.
  • the instant partial esters may be employed in the acid (i.e. acidic or unneutralized) form or as neutralized salts. Suitable salts are those of alkali metals such as sodium and potassium, alkaline earth metals such as magnesium, and ammonium and amine salts such as triethanolamine, decylamine, and the like.
  • the esters of the present invention are generally water soluble, i.e.
  • esters being sodium butyl orthophosphate (mixed primary and secondary ester), a mixture of approximately equal molar proportions of the mono-ester and di-ester of orthophosphoric acid and lauryl alcohol, di-sodium monomyristal orthophosphate, the sodium salt of the mixed monoand di-ester of orthophosphoric acid and the fatty alcohols derived from coconut oil fatty acid by hydrogenation thereof, the sodium salt of the mixed monoand di-ester of orthophosphoric acid and the fatty alcohols derived from hydrogenated tallow fatty acid, the sodium salt of the mixed monoand di-ester of orthophosphoric acid and oleyl alcohol, and the sodium salt of the mixed monoand di-ester of orthophosphoric acid with either decyl alcohol or tridecyl alcohol.
  • suitable esters being sodium butyl orthophosphate (mixed primary and secondary ester), a mixture of approximately equal molar proportions of the mono-ester and di-ester of orthophosphoric acid and lauryl alcohol, di-s
  • Additional suitable phosphoric acid esters include those derived from pyrophosphoric acid, such as the sodium salt of the di-ester of 2- ethylhexyl alcohol and pyrophosphoric acid, as well as those derived from tripolyphosphoric acid such as, for example, R Na -(P O wherein R is 2-ethylhexyl or capryl.
  • pyrophosphoric acid such as the sodium salt of the di-ester of 2- ethylhexyl alcohol and pyrophosphoric acid
  • tripolyphosphoric acid such as, for example, R Na -(P O wherein R is 2-ethylhexyl or capryl.
  • other alkali metal or alkaline earth metal salts such as the potassium and magnesium salts may be employed in place of the foregoing sodium salts. It is particularly preferred to employ salts of primary and secondary esters of orthophosphoric acid and higher (e.g.
  • C C monohydric primary aliphatic alcohols for instance disodium monolauryl orthophosphate, magnesium monolauryl orthophosphate, and disodium monooleyl orthophosphate, as these particular ester salts have been found to be characterized by outstanding polishing, anti-seizing, and hydrophobic film-forming properties when used with steel wool to scour aluminum in the presence of water.
  • Steel wool to be employed for scouring aluminum may be contacted with the instant partial esters at the moment of scouring or at any time prior thereto.
  • steel wool pads may be impregnated, coated, or otherwise loaded or charged with a suitable ester, and the ester may be employed alone or in "conjunction with additional agents suitable for use with steel wool.
  • the steel wool may be of any grade, e.g. No. 00 or No. Land of any otherwise desirable analysis or carbon content.
  • the instant esters in steel wool which is also loaded with a detergent or detergent composition in order to facilitate soil removal and grease emulsification.
  • a detergent or detergent composition may be provided separately from the body of'steel wool, e.g. in the form of a powder, cake, liquid, paste, cream or the like, to be applied to the steel wool or used in conjunction therewith at the time of scouring.
  • such detergent compositions are combined with the instant esters to form a fluid, e.g. paste, liquid or cream, or solid, erg. particulate or unitary, product which is used as .an integral part of a steel wool scouring pad, as by coating, impregnation, envelopment, or mechanical entrapment in or on the steel wool.
  • Organic detergents which are preferably used in conjunction with or as part of a body of steel wool employed with an aliphatic phosphate ester according to the instant invention include anionic, non-ionic and amphoteric nonsoap detergents, especially those which generate at least about mm. of foam at 0.1% concentration by weight in the Ross-Miles pour foam test (see Ross and Miles, Oil and Soap, May 1941, pages 99-102; or see Ross and Miles, US. Patent 2,315,983).
  • Suitable such anionic detergents are well known and include alkali metal and alkaline earth salts of various organic sulfates and sulfonates such as the higher alkyl aryl sulfonates, e.g., the sulfonates of alkylated benzene, toluene, cresol, naphthalene and the like in which the alkyl group contains from about 10 to 18 carbon atoms, for instance, sodium pentadecyl benzene sulfonate and sodium tetrapropylene benzene sulfonate; higher fatty alcohol sulfates such as potassium lauryl sulfate and the lithium salt of sulfated alcohols derived from coconut oil by reduction; sulfated higher'fatty acid 'monoglycerides such as the sodium or magnesium salts of monosulfated glyceryl monomyristate; and the higher fatty acid N-substituted taurates such
  • Amphoteric detergents which may be used alone or in admixture with other detergents include water soluble salts of N-higher alkyl beta-aminopropionic acid such as the triethanolamine salt 'of-N-lauryl'beta-alanine, and the sodium salt of N-higher alkyl beta iminodipropionic acid, the water soluble salts of higher-alkyl substituted quaternary hydroxy'cycloimidinic'acid metal alcoholates such as the disodium salt of "l-(z hydroxyethyl)-l-(carboxymethyl)- 2 hendecyl-4,5 dihydro-imidazolinium hydroxide, and water soluble salts of trialkyl ammonium carboxylic acids such as the sodium salt of lauryldimethylammonium aceticacid.
  • N-higher alkyl beta-aminopropionic acid such as the triethanolamine salt 'of-N-lauryl'beta-alan
  • Suitable non-ionic detergents includethe solid-water-soluble ethylene oxide condensates of waterinsoluble (molecular weight 900 to 2,400) polypropylene glycols, and thehigher fatty acid alkanolamides such as lauric monoand di-ethanolamide.
  • normally solid synthetic detergents normally' liquid high'foaming detergents such as the ethylene oxide condensates of alkyl phenols, e.g., nonyl phenol condensed with from 6 to 16 mols of ethylene oxide, may also beused, in which case they may, if desired, be mixed with sufficient buffer salt, starch or similar solid material to absorb the liquid and in effect, convert the detergent to a normally solid form.
  • the present steel Wool products befree of or used in the absence-of higher fatty acid soap (in'view of itstendency to become rancid and to form insoluble curds on-exposure to hard water), some soap may be present. In such cases, it is desirable to also have present sufficient non-soap organic detergent to protect the soap from the harmful effects of hard water.
  • the beneficial properties of the instant phosphate esters are especially significant in that they remain at a high level of efficacy in the presence of inorganic salts, which are generally antagonistic toward potential aluminum polishing agents for use in conjunction with steel wool.
  • inorganic salts which are generally antagonistic toward potential aluminum polishing agents for use in conjunction with steel wool.
  • alkaline bufler salts examples include alkali metal detergent builder salts such as the alkali metal carbonates, e.g., sodium carbonate, sodium sesquicarbonate, and sodium bicarbonate, as well as sodium and potassium silicates, 'borax, and alkali'metal phosphates such as pentasodium tripolyphosphate, tetrasodium pyrophosphate and trisodiumphosphate. It is particularly preferred to use the non-phosphate buffers such as sodium carbonate as it hasbeen found; that the beneficial properties of the instant organic-esters are maintained at their highest levels in the absence of-inorganic phosphate salts.
  • alkali metal detergent builder salts such as the alkali metal carbonates, e.g., sodium carbonate, sodium sesquicarbonate, and sodium bicarbonate, as well as sodium and potassium silicates, 'borax, and alkali'metal phosphates such as pentasodium tripolyphosphate, t
  • the present phosphate esters may be com- 'bined'with appropriate detergents, plasticizers, and optionally'but preferably, with inorganic alkaline detergent builders to form permanently plastic paste-fillers'for steel wool pads.
  • Suitableplasticizers for such paste-fillers include liquid or fluid, essentially non-volatile, water soluble or dispersible non-ionic surface active agents such as the normallyfiuid alkylolamides of higher fatty acids containing to 18 carbon atoms, for example, thediethanolamides of oleic or coconut oil'fatty-aci'ds, and'the correspondingfluid glycerolamides, as well as the wellknown'liquid non-ironic detergents of the ethylene oxide condensate type, e.g., ethylene oxide condensates of higherfatty acids, fatty acid amides, and C alkyl phenols.
  • the instant organic phosphate ester is employed in a small but effective amount suflicient to exert a polishing action on aluminum during scouring thereof by steel wool in the presence of an aqueous medium.
  • the exact minimum amount necessary to such action, as well as the anti-seizing and hydrophobic film-forming action exhibited by the instant esters, is dependent upon the fiber diameter of steel wool employed, the metallurgical properties of the steel wool and aluminum to'be scoured, and the types and amount of other constituents present'in the pad, particularly inorganic salts.
  • very small amounts may sufiice, e.g.
  • Example I A. permanently plastic paste filler for steel wool scouring pads consists 10f:
  • Percent Disodium monolauryl orthophosphate 7 Diethanolamide of coconut oil fatty acids .18 sodiumidodecyl benzenesulfonate (containing about 15% vsodium sulfate) 30 Sodium carbonate (anhydrous) 45
  • the-above ingredients are mixed to form a uniform, permanently plastic detergent paste, grams of this paste are spread along one face of a strip of 0 gauge steel wool weighing7 grams, the strip isrolled up with the paste-carrying face on the inside, and the pad is then compressed to impart a desired shape and'form.
  • Example III A scouring pad exhibiting excellent polishing properties on aluminum may be prepared as set forth in Example II using a paste having the following composition:
  • the detergent of this example may be replaced by sodium lauryl sulfate or the sodium or potassium salt of a sulfated monoglyceride of coconut oil fatty acids.
  • Example IV The following composition may be used in lieu of that of Example II to achieve substantially the same results:
  • Example V Pads prepared containing the following mixed monoand di-esters in lieu of the partial phosphate ester of Example IV exhibit substantially the same properties as those of Example IV: sodium butyl orthophosphate, sodium Z-ethyl hexyl orthophosphate, sodium stearyl phosphate, and sodium oleyl phosphate.
  • Example VI The amphoteric detergent of the foregoing example may, if desired, be replaced by the disodium salt of 1- Z-hydroxyethyl 1 (carboxymethyl -2-(higher alkyl) 4,S-dihydro-imidazolinium hydroxide wherein the higher alkyl group is derived from coconut oil fatty acids (Miranol CM).
  • Example VII A pad of steel wool Weighing 7 grams is impregnated with 10 grams of the following composition:
  • the resulting pad foams well in water, and when used in the dishpan in the course of scouring and cleansing soiled aluminum cooking vessels, readily removes soil therefrom without scratching, seizing or dragging on the aluminum surfaces of the vessels.
