Improvements in the Manufacture of Soaps and Cleansing
Compositions.
I, FREDERICK RAINBOW of 43 Duke Street High Town Luton in the County of
Bedford Straw Hat Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a peculiar process or Method of Converting Mineral oils
known as Kerosene and Petroleum into Soaps of Hard, Soft, Dry, and Fancy
Manufacture, Washing powder and cleansing Compositions respectively, by the
compounding and mixing of two ounces, more or less, of the aforesaid mineral oils,
with one pound of Soap or the necessary products of animal, vegetable and mineral
substances, used in manufacturing the same into soaps and cleansing compositions, by
the aid of, or chemical action of Alkali, by which process and the converting and
mixing of the aforesaid mineral oils with soaps and cleansing compositions, the
corrosive or injurious properties of the Alkali is neutralised, and thereby becomes
harmless in its use for washing, cleansing and disinfecting purposes.

page_text: I FREDERICK RAINBOW of 43, Duke Street, High Town, Luton in the County of
Bedford Straw Hat Manufacturer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to a peculiar process or Method of converting and mixing
Mineral oils, known as Kerosene and Petroleum into soaps of Hard, Dry, and Fancy
manufacture, washing powder and cleansing compositions respectively.
My method of compounding and mixing the aforesaid mineral oils with the
necessary products of animal vegetable and other nineral substances used in manu-
facturing the same into soaps, washing powder and cleansing compositions by the
aid of, or, chemical action of Alkali is as follows:-1 dissolve or boil the necessary
animal and vegetable products used in manufacturing soaps, washing powder
and cleansing compositions, with an Alkali or Soap Makers Lye, until a sapo-
naceous mixture is formed, which is allowed to cool to about 100 degrees Far:
heat; to this saponaceous mixture, equal to every pound of soap, I add 2 ounces,
more or less, of the aforesaid mineral oils with 15 grains, more or less of carbolic
acid in a crystalised form, or 1 drachm, more or less, of the said acid in a liquid
form, and for disinfecting purposes, 1 ounce, more or less, of a solution of chloride
of lime These compounds are then briskly stirred until the aforesaid mineral
oils become thoroughly incorporated and mixed with the saponaceous mixture,
which if intended for hard soaps, is, while in a liquid state poured into boxes
or moulds, if for liquids or soft soaps into cans, if for dry soaps or washing powder,
in packages when cold, previously pulverised; the said mineral oils are not required
to be mixed or boiled in the first instance with the Alkali or Lye, by the above-
mentioned process or method the offensive odour of the said mineral oils is absolutely
neutralised or destroyed, and is thereby rendered suitable for soap making purposes;
The said mineral oils neutralises the corrosive or injurious action of any surplus
Alkali not taken up or destroyed by the other ingredients, and becomes harmless in
its use for washing, cleansing purifying and disinfecting purposes-That soaps
washing powder, and cleansing compositions made and manufactured by the above-
mentioned process or method are not acted upon by a damp atmosphere and may be
kept for any length of period without any material deterioation by evaporation, while
the peculiar feature or process relates principally in the mixing and incorporating
the aforesaid mineral oils with other compounds into soaps, washing powders, and
cleansing compositions.
Soaps, washing powders, and other cleansing compositions, prepared and manu-
factured as hereinbefore described are rendered buoyant, which enables them to be
readily detected when used in the bath.

page_text: A further advantage attending my invention is that the soaps etc. is not corrosive
or destructive to fabrics, at the same time it contains all the cleansing properties
common to other soaps washing powders etc. and is not harsh for toilet use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1-Soaps, washing powders, and other cleansing compositions, consisting of the
ingredients and proportioned as hereinbefore set forth and prepared and manufactured
substantially as and for the purposes described.
