I JULIUS QUAGLIO of 25 Louisen Strasse, Berlin, Germany, Engineer do
hereby declare the nature of my said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
It has been found by experience that the ordinary or so-called Violet or toilet
powder is mostly a mixture of the finest starchy flour such as rice flour, white flour,
maize flour, mixed with mineral colours such as talc, zinc white and permanent white
which exercises an injurious effect upon the skin and showing itself in such a manner
that after a continued use of such powders the skin becomes brittle and dry, like
parchment. This appearance of the skin results from the fact that the said powdered
substances deprive the same from its serosity as fatty principle and thus to a certain
extent dries it.
In order to maintain the skin in a healthy condition when the use of powder is
rendered necessary, it is requisite to so.ordain the manufacture of such powder as to
incorporate therewith the same fatty matter as that of the skin which the latter will
thus be able to easily assimilate.
There occurs truly in commerce a class of powder which is called fat or greasy
powder but this does not contain the slightest trace of grease or fat and even if such
was the case the process hereinafter described for the preparation of my Lanolin
powder would still be novel and peculiar.
Amongst all fatty matters Lanolin has been found by experience the substance
which is most easily and to a greatest extent absorbed by the skin. Lanolin however
cannot be mixed such as it is with powdered mineral or organic substances. But if
the said Lanolin is placed in a solvent such as ether, alcohol, chloroform, acetone or
the like, it is partially dissolved therein and partly forms an emulsion therewith.
Magnesia being now added thereto the liquid solvent is expelled by evaporation and
a homogeneous loose mass is obtained which is rich in fatty matters and appears as
an uniform substance which I term "Lanolin-Magnesia."

page_text: The preparation of the latter compound must be carried out during a prolonged
rest and under the action of heat, the solvent being distilled off and thus regained for
further use.
According to my experiments magnesia is highly suitable for the formation of such
loose vehicles of fat.
Similar Lanolin compounds may be obtained with venetian talc, white of zinc,
(oxide of zinc) white of barytes, chalk, but the high specific gravity of these substances
seem generally to interfere, when mixed with Lanolin, with the homogeneity of the
mixture.
The Lanolin-magnesia thus prepared or the other combinations of Lanolin above
mentioned can easily be further mixed with suitable component parts of toilet
powders, such as rice powder and the like and I term the powders thus manufactured
Lanolin powders.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The process for the manufacture of Toilet or Face Powder (Lanolin powder) by
incorporating or mixing Lanolin and partial solvents with magnesia or an equivalent
light mineral powder, the solvents being driven from this mixture by natural
evaporation and the aid of heat, the loose and greasy compounds of Lanolin and
Magnesia (or it may be white of zinc, white of barytes, or chalk) mixed with suitable
substances now used in the manufacture of Toilet powders.
2. The manufacture of Lanolin powder and its use for toilet purpose as
described.
