"IMPROVEMENTS IN THE MANUFACTURE OF SOAP AND OTHER MATERIALS USED
FOR LIKE PURPOSES
Our invention relates to improvements in the manufacture of soap, washing
powder and other materials used for like purposes, and has for its objects to
improve the quality and to reduce the cost of the soap or other material.
We have discovered that by combining a suitable proportion of starch sugar
(grape-sugar or glucose) with the ingredients usually employed in the manufacture
of soap the quality of the latter is greatly improved, and the soap is, moreover,
rendered more agreeable to the skin than heretofore, and, by reason of the low
price of grape sugar or glucose as compared with that of ordinary soap, the cost of
manufacture is considerably reduced. Our invention is based upon this discovery
and comprises the methods or processes hereinafter described, that is to say :-
According to one method or process, during the manufacture of the soap, washing
powder, or other material, we add to the ingredients ordinarily employed, starch-
sugar (grape-sugar or glucose) either in a liquid or a solid state, and in, or about in,
the following proportions, viz-One part of starch-sugar (grape-sugar or glucose)
and three parts of soap or of the ingredients ordinarily employed in the

page_text: manufacture thereof. These proportions may, however, be somewhat varied
according to the quality of the soap to be produced.
The ingredients are mixed in a manner similar to that ordinarily employed in
the saponification of oils and fatty matters, but, this operation can be varied
according to the machinery or apparatus in use at the soap works, or the quality of
the soap to be produced. We prefer that the quality or richness in carbon of the
grape-sugar or glucose should be equal, or nearly equal, to that of glycerine, but
ordinary grape-sugar or glucose is suitable for many classes of soap.
According to another method or process, we manufacture the soap, washing
powder, or other material in the ordinary manner and then mix with the same
starch-sugar (grape-sugar or glucose) in the proportions above stated.

"IMPROVEMENTS IN THE MANUFACTURE OF SOAP AND OTHER MATERIALS USED
FOR LIKE PURPOSES
"
Our invention relates to improvements in the manufacture of soap, washing
powder and other materials used for liko purposes, and has for its objects to
improve the quality and to reduce the cost of the soap or other material.
We have discovered that by combining a suitable proportion of starch-sugar
(grape-sugar or glucose) with the ingredients usually employed in the manufacture
of sonp, the soap is greatly improved in quality, and is rendered more useful and
effectual when employed for manufacturing purposes. It is, moreover, rendered
more agreeable to the skin than soap as heretofore usually manufactured, and, by
renson of the low price of starch-sugar as compared with that of ordinary soap, the
cost of manufacture is considerably reduced. Our invention is based upon this
discovery and the improved soap is made in the manner hereinafter described, that
is to say:
According to one method or process, during the manufacture of the soap, washing
powder or other material, we combine with the fatty or oily matter and the alkali,
with or without other ingredients ordinarily employed, starch-sugar (grape-sugar or
glucose) in either a liquid or a solid state and in, or about in, the following
proportions, viz-One part of starch-sugar (grape-sugar or glucose) and three
parts of soap or of the ingredients ordinarily employed in the manufacture thereof.
These proportions may, however, be varied according to the quality of the soap to
be produced.
The starch-sugar can, if desired, be made at the soap works and is then used
before it has attained its ordinary commercial form, that is to say, while it is in a
liquid state, and it is sufficiently diluted to form a very cheap ingredient for use in
the manufacture of the soap. The liquid starch-sugar should be used at a density
of about 12° Baumé, more or less. The other ingredients of the soap are added in
the usual manner and in suitable proportions according to the quality of soap
desired.
When the starch-sugar is used in its commercial form, it is added to the
ingredients of the soap in either a solid or a liquid state (in the latter case the
sugar is dissolved either in water or by the application of heat) and this addition
may be effected either before or after the saponification takes place. With some
low classes of soap the sugar must be added before saponification takes place,
whilst with most of the higher qualities of soap the sugar can be added after the
saponification has taken place, and while the mixture is in a semi-liquid state.
In some cases ordinary soap, after it has been manufactured, is dissolved by the
application of heat until it assumes a semi-liquid form and the desired quantity of
starch-sugar is then added thereto in either a solid or a liquid state.
After either of the above described processes, the improved soap is placed in
moulds and allowed to set or harden in the ordinary manner.
We prefer that the quality or richness in carbon of the starch-sugar should be
equal or nearly equal to that of glycerine, but ordinary grape-sugar or glucose is
suitable for many classes of soap. Cleaning soaps for scouring cloths, when combined

page_text: with starch-sugar in the manner above described, will be found to give excellent
results.
Having thus fully described our, said Invention and the manner of performing
the same, we wish it understood that we claim.
First. The above described improved soap formed by the combination of
starch-sugar (grape-sugar or glucose) with fatty or oily matter and an alkali,
with or without other ingredients ordinarily employed in the manufacture of soup.
Second. The above described method or process of manufacturing the improved
soap, consisting in combining the starch-sugar in a liquid state, before it has
attained its commercial form, with fatty or oily matter and an alkali, with or
without other ingredients, and then placing the mixture in moulds and allowing it
to set or harden, substantially as set forth.
In Witness whereof we the said James Tarbotton Armstrong and William
Bostock have hereunto set our hands and seals this Twenty-seventh day
of April in the year of our Lord One thousand eight hundred and eighty
three
