Definitions

  • This invention relates to a glass cleaning preparation and more particularly to a preparation for cleaning the windscreens of motor or like vehicles.
  • glass cleaning preparations there are a number of glass cleaning preparations on the market with generally non specialised application. However, they are far from satisfactory for a number of reasons. For example, many glass cleaning compositions are good at cleaning glass such as house windows, but they leave a surface coating on the glass which interferes with the correct operation of the windscreen wipers. Other preparations require to be washed off after use or dry in such a way as to leave smears on the glass.
  • This invention seeks to provide a glass cleaning preparation in which some or all of the above disadvantages are removed or substantially reduced and which is eminently suitable for cleaning the windscreens of motor and like vehicles.
  • a glass cleaning preparation comprises a light abrasive, finely divided silica, water and alcohol in proportions suitable to produce a cream and a wetting agent.
  • the finely divided silica may be fumed, precipitated or in colloidal form.
  • the light abrasive comprises calcium carbonate in precipitated form suitably in the form known commercially as "light calcium carbonate".
  • the alcohol is preferably ethanol but may suitably include methanol and isopropanol.
  • the wetting agent may be propylene glycol-ethylene glycol fatty alcohol polymer.
  • the preparation comprises, by weight, 4 - 17% precipitated calcium carbonate, 1.7 - 6% fumed silica, 47 - 77% water, 8 - 38% ethanol and 0.5 - 4% wetting agent.
  • the preparation comprised:- 100 g calcium carbonate (light) 50 g fumed silica 800 ml water 250 ml ethanol 24 ml propylene glycol-ethylene glycol fatty alcohol polymer
  • 50 g fumed silica powder was placed in a mixing vessel to which 800 cc. water was then added. The contents of the mixing vessel were stirred to a smooth creamy consistency. Then the calcium carbonate powder was added to the mixing vessel and the contents were again stirred to a smooth creamy consistency.
  • the proportions used could suitably be varied in the ranges:- 50-200 g calcium carbonate 20-70 g fumed silica 6 -48 ml propylene glycol-ethylene glycol fatty alcohol polymer
  • the amount of water and ethanol used would depend on the amount of powder present, the liquid being in sufficient quantities to provide a creamy smooth substance. While it is desirable that the ratio of ethanol to water should be of the order of 5 : 16 parts by volume, this ratio could be varied over a wide range, e. g. between 1 : 8 and 1 : 1.
  • alcohols may be used instead of ethanol, for example methanol and isopropanol.
  • the finely divided silica could be obtained by precipitation or used in colloidal form.
  • Other forms of calcium carbonate, such as heavy chalk, could be used.
  • Talc, Kaolin or other suitable light abrasives may be used instead of the calcium carbonate.
  • Other wetting agents could be used, but these should all be low foaming.
  • the glass cleaning preparation above described may suitably be dispensed directly onto the windscreen to be cleaned from a squeeze bottle.
  • the preparation is rubbed into the glass with a tissue or soft cloth and allowed to dry. After a short time a residual dry powder is left and this can be removed by wiping with a soft dry cloth leaving a clean dry windscreen.
  • the calcium carbonate and the fumed silica provide a light abrasive action.
  • the fumed silica which is a thixotropic material, acts to adhere the preparation to the glass and prevent it from running off before it has been rubbed in.
  • the water and ethanol enable the ingredients to be emulsified into a smooth cream, the ratio of the two determining the drying time required after application.
  • the use of a wetting agent ensures that no residue of the preparation is left adhered to the screen.
