GLASS CLEANING PREPARATION <br><br>
This invention relates to a glass cleaning preparation and more particularly to a preparation for cleaning- the 5 windscreens of motor or like vehicles. <br><br>
In motor vehicles, the ability to see clearly through the windscreen is critical not only for the safety of the driver and his passengers but also for the safety of 10 other road users. For this reason, all motor vehicles travelling on public highways are fitted with windscreen wipers whose job is to clear the windscreen of any rain thereon and, to a limited extent, with the help of washers, to remove mud and grime from the windscreen. <br><br>
15 <br><br>
However, for the windscreen wipers to work satisfactorily, it is essential that grease and other matter which sticks to the windscreen be removed at regular intervals as otherwise the wipe becomes streaky 20 and visibility is impaired. <br><br>
O <br><br>
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 25 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 30 after use or dry in such a way as to leave smears on the glass. <br><br>
23 MAR1990S <br><br>
.T^is 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 <br><br>
«.) j. o I JL <br><br>

of motor and like vehicles. <br><br>
According to the invention, a glass cleaning preparation comprises a light abrasive, finely divided silica, water 5 and alcohol in proportions suitable to produce a cream and a wetting agent. <br><br>
The finely divided silica may be fumed, precipitated or in colloidal form. <br><br>
Preferably, 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 15 methanol and isopropanol. The wetting agent may be propylene glycol-ethylene glycol fatty alcohol polymer. <br><br>
In a particular formulation of the glass cleaning preparation in accordance with the invention, the 20 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. <br><br>
The invention will now be described in greater detail by 25 way of example. <br><br>
In a particular example of a batch of glass cleaning preparation, the preparation comprised:- <br><br>
30 100 gm. calcium carbonate <light> <br><br>
50 gm. fumed silica <br><br>
"fiSJO cc. water <br><br>
250 cc. ethanol <br><br>
10 <br><br>
24 cc. propylene glycol-ethylene glycol fatty alcohol polymer <br><br>
tUu'ti <br><br>
3 <br><br>
To formulate the preparation, 50 gm. fumed silica powder was placed in a mixing vessel to which <300 cc. water was then added. The contents of the mixing vessel were stirred to a smooth creamy consistency. Then the calcium 5 carbonate powder was added to the mixing vessel and the contents were again stirred to a smooth creamy consistency. <br><br>
At this point, 250 cc. ethanol and 24 cc. propylene 10 glycol-ethylene glycol fatty alcohol polymer were added as a mixture and the the final preparation was again stirred to a smooth consistency. The preparation was then ready for bottling. <br><br>
15 The proportions used could suitably be varied in the ranges: - <br><br>
50-200 gm. calcium carbonate 20-70 gm. fumed silica 20 6 -48 cc. propylene glycol-ethylene glycol fatty alcohol polymer <br><br>
© <br><br>
The amount of water and ethanol used would depend on the amount of powder present, the liquid being in sufficient 25 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. <br><br>
30 <br><br>
Other alcohols may be used instead of ethanol, for , ejca^ple methanol and isopropanol. The finely divided silica could be obtained by precipitation or used in colloidal form. Other forms of calcium carbonate, such 35oe»s heavy chalk, could be used. Talc, Kaolin or other 23 MAR 1990 suitable light abrasives may be used instead of the <br><br></p>
