Patent GB-430024-A (GB)
Title: Process of producing mineral oil powders
Filed: 1933-12-12
Abstract: Mineral oil powders are obtained by converting mineral oils such as petroleum, brown coal tar oil, and naphtha into semi-liquid condition by treatment with soap powder and a mixture of paraffin wax and beeswax, the quantity of beeswax being at least 1 per cent of the weight of oil, and then adding pulverulent substances.  The term "beeswax" includes the synthetic wax known as "I.G. wax."  Part of the beeswax may be replaced by other waxes, and the mixture of paraffin and beeswax may amount to about 10 per cent of the weight of oil.  The waxes may be mixed while heating with petroleum in which a few per cent of soap are suspended.  While cooling, 30--40 per cent by weight of thickeners such as starch, magnesium carbonate, or kaolin are added. Pulverulent substances such as talc or magnesium carbonate are then added in amounts up to 100 per cent by weight. The powder may be aromatized and is suited for disinfecting, destruction of parasites, or as a remedy for perspiration and chafing.  In an example: 20 g. each of paraffin and beeswax are melted with 1 litre of petroleum containing 20 g. of soap powder. The mixture is stirred and kept at 100 DEG  C. for some time.  During cooling, but while still hot, 100 g. of starch and 200 g. of magnesium carbonate are added.  A further 300 g. of talc and 900 g. of p  magnesium carbonate are then added with continued stirring. The Specification as open to inspection under Sect. 91 includes the use of the constituents of beeswax in place of the latter. This subject-matter does not appear in the Specification as accepted.ALSO:Mineral oil powders are obtained by converting mineral oils such as petroleum, brown coal tar oil, and naphtha into semi-liquid condition by treatment with soap powder and a mixture of paraffin wax and beeswax, the quantity of beeswax being at least 1 per cent of the weight of oil, and then adding pulverulent substances.
