Definitions

  • the present invention tends to overcome these disadvantages and to markedly improve scouring pads, in particular those made from metal wool, and has as its main objects to provide an impregnating agent which clings to the surfaces of the fibers, inhibits corrosion and staining of the pad or carrier in use and provides surface active properties, such as foaming, lathering, etc. without being rapidly dissolved.
  • the scouring pad containing the soap composition remains substantially elastic and pliable when used during the washing and scrubbing operations.
  • a soap made in accordance with this invention may advantageously be used to replace the soap compositions presently employed in commercial steel Wool pads and to fulfill all the needs and requirements of the practice. While reference hereinafter is primarily made to steel Wool pads, it is to be understood that any other metal or plastic fiber may be substituted therefor.
  • the soap impregnating agent for this purpose may be composed of the following ingredients within the following ranges:
  • Water is employed at 25-50% by weight of the soap composition to provide a soap which may be applied to the scouring pad ribbon by any conventional means, e.g. dipping, spraying, etc. and which sets upon cooling.
  • Sodium nitrite when employed at 1-3% by weight of the soap composition acts in combination with the other components to provide improved rust resistant properties in steel wool scouring pads. While sodium nitrite has been used in the past for such purposes, the soap composition of the present invention provides significantlysuperior rust inhibiting properties.
  • the alkali metal carbonate employed in the present invention at 3-10% by weight of the soap composition is selected from the group consisting of sodium or potassium carbonate. It creates a desired fluidity in the soap composition to provide maximum distribution of soap throughout entire cross section of the scouring pad. Furthermore, the alkali metal carbonate and particularly the sodium carbonate provide improved setting of the soap composition after application on the scouring pads due to its high Water of crystallization.
  • the polyglycols when employed in an amount less than 6% by weight of the soap composition, act as humectants to prevent the soap composition from drying out in storage with resultant high losses due to dusting.
  • Typical of the humectants which may be employed are polyethylene glycol, sorbitol, manitol, glycerine and the like. Glycerine is the preferred humectant for use in the present invention.
  • the potassium high lauric acid soap employed in the present invention at 10-45% by weight of the soap composition may be made from a high lauric acid oil such as commercial coconut oil, palm kernel and babassu nut oil which has been saponified to provide the potassium soap. It is preferred to employ coconut oil soaps having lower moisture contents. Where commercially available potassium coconut oil soaps are employed, it may be necessary to reduce the moisture level of the soap composition after preparation in order to provide a water content of 25-50% by weight.
  • a high lauric acid oil such as commercial coconut oil, palm kernel and babassu nut oil which has been saponified to provide the potassium soap. It is preferred to employ coconut oil soaps having lower moisture contents. Where commercially available potassium coconut oil soaps are employed, it may be necessary to reduce the moisture level of the soap composition after preparation in order to provide a water content of 25-50% by weight.
  • the alkali metal high lauric acid soap of the present invention is selected from the group consisting of sodium and potassium soaps and employed at O.5-22.5% by weight of the soap composition. It may be obtained from a high lauric acid source such a commercial coconut oil, palm kernal oil and babassu nut oil or from the fatty acids of such oils which are saponified or neutralized to provide the alkali metal soap.
  • the alkali metal tallow soap of the present invention is selected from the group consisting of sodium and potassium soaps and employed at 5-45 by weight of the soap composition. It is prepared by saponification of commerically available tallow or neutralization of fatty acids derived from tallow or other sources that give predominantly palmitic, stearic and oleic acids. It is essential that unsaturated oleic acid which is a normal component of many sodium tallow soaps be at a level of less than 18% by weight of the total soap composition. It has been found that levels of oleic acid in excess of 18% of the total soap composition cause noticeable foam deterioration.
  • the foam builder employed in the present invention at less than 6% by weight of the soap composition may be a saturated fatty alcohol having a chain length of C to C
  • the foam builders frequently create handling problems and provide the soap composition with an undesirable physical appearance. While the lower chain length, e.g., C to C fatty alcohols provide acceptable results from the standpoint of foam characteristics, they may be less desirable for some uses due to their odor which may be objectionable. Where the higher chain length e.g. C to C fatty alcohols are employed, it has been found preferable to use such fatty alcohols in combination to obtain optimum foaming effect.
  • Typical of the fatty alcohols that may be employed in the present invention are octanol, decanol, tetradecanol, hexadecanol, octadecanol, dodecanol alcohols and the like.
  • the dodecanol is preferred in carrying out the present invention.
  • the foam builders unexpectedly extend the use life of the scouring pads as compared to equivalent pads wherein no foam builder is added to the soap.
  • the chloride and sulfate ion concentration in the soap composition of the present invention must be less than 1% by weight of the total composition and preferably less than 0.2% by weight.
  • Such ions are commonly a carry-over in salts formed in conventional soap making processes and exist in many commercial soap sources.
  • soap compositions of the present invention may be applied to scouring pads by any common application means, it has been found that the soap composition is particularly suitable for use in a process utilizing a spray application.
  • soap compositions of the prior art due to their physical characteristics have been unsuitable for spray application on scouring pads.
  • Such soaps when spray application was attempted, generally provided pads having extremely poor appearance, uneven soap distribution and in addition thereto, the spraying resulted in high soap losses in the manufacturing operations.
  • a particularly satisfactory product may be prepared with the present soap composition or other suitable sprayable detergent which may be soap or synthetic detergent using a method wherein a flat ribbon of suitable scouring pad wool or fibers having a thickness and width sumcient to provide finished scouring pads of desired shape is sprayed with a detergent composition on at least one side.
  • the detergent is supplied through a spray nozzle and pump connected to a suitable source of supply.
  • the ribbon then has placed upon it, at spaced intervals, metered quantities of a detergent core in a semi-solid, plastic, paste-like form which is capable of maintaining its position and shape as a discrete body.
  • the detergent may be the same detergent used in spraying or any other compatible detergent.
  • the frequency of discharge of the semi-solid core composition and the linear speed of the ribbon are so correlated as to provide discrete bodies of the core composition on the ribbon.
  • the ribbon may then be cut by cutting means at equally spaced intervals to provide each cut strip of ribbon with a unitary discrete body of soap.
  • the ribbon may be divided into desired lengths by tearing or cutting before applying the core.
  • the cut ribbon is rolled into a cylinder with the discrete body of detergent in the center and compressed to form -a finished scouring pad.
  • the term cut refers to the cutting or tearing of steel Wool or other ribbons to divide the ribbon into proper length.
  • steel wool is the scouring pad fiber employed. It has been found that the type steel wool employed may be varied considerably depending upon the abrasiveness and texture desired in the finishing scouring pad. Preferably, commercial steel wools having the grade in the order of about 1 to 00 are employed. It is preferred to employ long fibered steel wool capable of giving the finished pads desired elasticity and spring while at the same time reducing the number of short ends which can abrade the users hands.
  • any spray system capable of handling soap may be employed. It is desired to provide the finished ribbon with a uniform soap coating which is free from visual droplets or beads.
  • soap compositions When steel wool ribbon is employed, it is preferred to use a soap composition as the detergent to be applied Typically, spray nozzles having orifice diameters of about 0.0050.025 inch Will provide satisfactory results with most soap compositions.
  • the soap composition to be sprayed is maintained at a temperature above which the soap is fluid and may be atomized and below which the atomized soap dries too rapidly to permit satisfactory adhesion to the steel wool ribbon. At extremely high temperatures, the moisture in the soap flashes off instantaneously thereby partially drying the soap and reducing it adhesive properties.
  • soap compositions at temperatures in the order of about l10210 F. will provide satisfactory results.
  • soap compositions having temperatures in the order of about -l60 F. are employed.
  • the soap composition is sprayed onto the steel wool ribbon in an amount of about 3-7 grams of soap solids per 6 gram of steel wool ribbon. While the soap may be sprayed onto either or both sides of the fiattened steel wool ribbon, it is preferred in carrying out the present invention that the soap be sprayed onto one side of the steel wool ribbon.
  • the detergent employed in the core of the present invention may be any detergent composition which is compatible with the sprayed detergent composition employed and which can be extruded as a semi-solid, plastic, pastelike mass capable of substantially maintaining its position and shape as a discrete body after extrusion. It is preferred when soap is employed that about 0-3 grams of soap solids are employed per 6 grams of steel wool ribbon.
  • the steel wool pads are formed from steel wool ribbons having a length of approximately 18 inches and weighing about 6 grams.
  • the ribbon may be cut or torn before or after the soap core is applied by use of conventional steel wool tearing or cutting equipment.
  • the soap core is placed upon the steel wool and preferably located so that after formation of the pad the core is in the proximate center of the finished pad.
  • the cut or torn steel wool ribbon, preferably with the soap core on the soap-free side of the ribbon, is then rolled in the cylindrical form by conventional steel wool pad rolling equipment and then pressed in conventional steel Wool pad presses to form the finished pad.
  • the soap composition may be prepared by the following examples.
  • Example I A solution was prepared by dissolving 7 pounds of sodium carbonate and 2% pounds of sodium nitrite in 26.9 pounds of water and the solution heated to 140 F. in a crutcher. 32.1 pounds of molten 70% solids kettle soap containing 80% sodium tallow soap and 20% sodium coconut soap was addedto the solution with agitation. 10.5 pounds of 50%v potassium hydroxide solution and 20.5 pounds of coconut oil were simultaneously added to the previously prepared mixture with continuous agitation While maintaining the temperature of the mixture at 170 F. 3 pounds ofdodecanol was added to the mixture and agitation continued for an additional 90 minutes while the temperature was maintained at 170 F. to complete saponification.
