Complete Specification Accepted, 23rd Feb., 1889
I, THOMAS SAMUEL SAUNDERS of 16 Grove Terrace, Highgate in the County of
Middlesex; Chemist, do hereby declare the nature of this invention to be-as
follows:-
My invention has for its object the production of an improved soap baving án
emollient property in its action on the skin.
To this end my invention consists in considerably increasing the amount of the
saponifiable fatty or oily matters employed in the manufacture, for the purpose not
only of entirely exhausting and neutralizing the alkali but of having an excess of
fatty or oily substances more or less intimately distributed throughout the mass so
that the alkali naturally set free when a soap is dissolved in water cannot affect the
skin as it goes to saponify the excess of fat.
It will be understood that in other respects the process of manufacture employed
may be any of the usual ones, but in any case there must be a combination of
fat and soap: In a word, then, the idea of this soap is to supply an excess of fat
so that the alkali naturally set free by dissolving the soap in water will have
something to act upon instead of upon the epithelium of the skin.

page_text: I, THOMAS SAMUEL SAUNDERS of 16 Grove Terrace, Highgate, in the County of
Middlesex, 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:—
My invention has for its, object the production of an improved soap having an
emollient as well as cleansing property in its action on the skin.
It is known that directly after soap has been manufactured the saponification is
incomplete and therefore to improve same it is kept or allowed to stand a certain
length of time to mature during which the saponification proceeds, the free alkali
in the soap being to a certain extent sweated out, though not entirely so. It is
the presence of this free alkali in the soap when the latter is being used that is
injurious to the skin as it leaves it hard and dry.
According to my invention the amount of the usual saponifiable. fatty or oily
matters employed in the manufacture, is considerably increased so that any alkali
set free when the soap is dissolved in water will not affect the skin as in other soaps as
there is this excess of saponifiable fat present for it to act upon, while the excess
which I introduce is such that after saponification there is still an excess of unacted on
fat remaining which will act as an emollient to the skin by forming a film of oil
il or
fat thereon.
The saponifiable fats or oils which I employ may be any of the usual animal or
vegetable ones usually employed in soap manufacture, such as palm oil or other
fats or oils, easily saponifiable, 'as it is only an excess o the usual fat which 1
desire to have.
The percentage of the saponifiable fat which I prefer should remain as an excess in
the finished soap I have found by experiment should be about from two to three
per cent, though I do not confine myself to these exact proportions.
Shortly stated my invention consists in a superfatted soap, or a soap containing, an
excess of any saponifiable fats or oils..
It will be understood that the process of manufacture employed may be any of the
usual or improved ones and that the superfatting will not interfere in any way. with
any medicating or perfuming of the soap which may be desired.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
1 claim is :-
As an article of manufacture the improved soap containing an excess of saponi-
fable fatty or oily matter, substantially as described.
