PROVISIONAL SPECIFICATION.
An Improved Manufacture of Soap.
1, CHARLES ACHILLE SERRE, of 1, South West Road, Leytonstone, in the
County of Essex, Chemist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of an improved soap for toilet purposes
the object being to provide a powdered soap, the particles of which will not adhere
together or become clogged under the effect of atmospheric moisture the powder
remaining light and feathery thereby rendering it particularly applicable for
toilet use.
In carrying out my invention I take ordinary soap and slice, dry and powder it
in the usual manner after having first by analysis determined its moisture and I
make up the loss in weight of water by the addition of powdered tale which has
the effect of improving the cleansing qualities of the soap and helps to keep the
particles from adhering together. The powdered soap is then colored in the usual
manner after which the required scent or perfinne, which may be a spirit or an
essential oil, is added. This effect by mixing, dissolving or emulsifying the
perfume with olive oil, the mixture being gradually added to the soap which is
undergoing a finer powdering until the oily magma has covered every particle of
soap with a film of oil which, although invisible, is sufficient to ensure the
particles of soap from clogging under the effect of the moisture in the atmosphere.

COMPLETE SPECIFICATION.
An Improved Manufacture of Soap.
[, Charles AchILLE SERRE, of 1, South West Road, Leytonstone, in the
County of Essex, Chemist, 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 the manufacture of an improved soap, the object being
to provide a powdered soap, the particles of which will not adhere together or become
clogged under the effect of atmospheric moisture the powder remaining light and
feathery thereby rendering it particularly applicable for toilet use or for antiseptic
or disinfecting purposes.
In carrying out my invention I take an ordinary soap, preferably olive oil soap,
and slice, dry and powder it in any usual known manner after having first by analysis
determined its moisture and I make up the loss in weight of water by the addition
of powdered tale which has the effect of improving the cleansing qualities of the
soap and helps to keep the particles from adhering together; or instead of powdered
tale I incorporate with the powdered soap powdered pumice stone or silica and I
may add a suitable disinfecting or antiseptic substance according to the purpose
for which the soap is intended. The powdered soap is then coloured in the usual
manner after which the required scent or perfume, which may be a spirit or an
essential oil is added, the whole being then submitted to a further grinding operation
to reduce it to a fine homogeneous powder.
In practice I find it advantageous to mix, dissolve or emulsify the perfunc with
olive oil, the mixture being gradually added to the soap while it is undergoing the

page_text: re-grinding until the oily magna has covered every particle of soap with a film of
oil which, although invisible, is sufficient to ensure the particles of soap from
clogging under the effect of the moisture in the atmosphere.
By this means cau make antiseptic or toilet soaps according to any desired
formula always retaining the purity of the soap.
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
he purposes hereinbefore described.
