Definitions

  • the invention is an emulsion blend containing a toothpaste formula which is discharged from a dispensing container by a liquid gas propellant through a manually closable valve as foam, applied directly onto the bristles of a toothbrush.
  • Foaming of the toothpaste emulsion blend in it's various formulations occurs at the valve orifice exit as the emulsion comes under atmospheric pressure because a liquid gas is used as the propellant.
  • composition of packaging an emulsion blend containing a toothpaste formula in an aerosol type container by volume would be 90% to 95% emulsion and 5% to 10% liquid gas propellant.
  • Sufficient quantity of foam is discharged from a pressurised container through a manually operated valve to satisfactorily reduce to an acceptable level the flamable properties of liquid gas.
  • the loading of the toothpaste formula in the blended emulsion and the satisfactory discharge of the emulsion blend as a toothpaste foam is governed by the flow rate at the valve exit of .5 to 2 grams per second and the liquid gas propellant pressurised at 140 to 280 kilopascals.
  • Sufficient foam product is discharged by this method as to be economic and waste material is minimal.
  • the product volume to propellant ratio of 90% to 95% product and 5% to 10% propellant contributes to some reductions in the cost of the manufacturing process and even with low volume of propellant there is no loss of efficiency in product delivery or quality of foam.
  • the emulsifying agent for forming the emulsion being 'Span 81 ' (R) ur 'Emcol 14' (R), but the invention is not limited to these two emulsifying agents, for forming the emulsion of glycerine and or other carriers and water.
  • the emulsion blend contains abbrasives and polrshing agents, a softner-sorbital flouride compounds for strengthening tooth enamel. Harmless flavouring, colouring and perfume materials may also be included in the composition.
  • the emulsion blend may contain other optional ingredients in varying proportions.
  • Humectants which may contain a glycerine and sodium laurly sulphade mixture, from about 5% to about 75%. Abbrasive and polisning agents from about 30% tp about 55% of the composition. Compounds containing flouride from about 0.1% to about 5%. Materials for flavouring, colouring and perfumes and preservatives from about 1% to about 5%. An emulsifying agent from about 0.5% to about 10%, binders in an amount from about 0.5% to about 25%. Water at about 20% to about 70%.
  • the invention of which the emulsion blend is a step described in the foregoing is not to be limited to the description given because a substitution of equivalents for, elements, and materials could occur without going outside the scope of the invention step set out herein.
  • the present invention is the only invention known that dispenses a blended emulsion from a pressurised container as foam. Said method comprising the steps of :
  • the present invention causes the emulsion blend and the liquid gas to produce foam toothpaste when dispensed into the atmosphere.
  • toothpaste compositions are in paste, gel, powder or cream form and at some period of time of the prior art, been dispensed from collapsible tubes, squeeze containers and aerosol pressure packs.
  • the invention foamed toothpaste and method for producing same is new and innovative to the prior art.
