PROVISIONAL SPECIFICATION.
An Improved Toilet and Nursery Powder.
I, HUGO WALDEMAR LANGBECK, of No. 2 Claremont Villas, Loughton, in the
County of Essex, Analytical Chemist, do hereby declare the nature of this invention
to be as follows:-
My invention has for its object the production of a toilet or nursery powder, which
shall have both a drying, soothing, and healing action when applied to the skin.
For this purpose I mix purified wool-fat or the preparation thereof known as
"Lanolin" with any suitable absorbent powder, such as starch, flour, fullers earth,
kaolin, french chalk, and the like, taking the two ingredients in such proportions as to
leave the mixture in a perfectly dry pulverulent condition.
Thus for example I find that a good product is formed by mixing about one part of
the purified wool fat or "Lanolin" with about nine parts of the above mentioned
materials in a finely powdered condition, to which may be added any desired innocuous
colouring pigment, such for example as carmin, and it may also be flavoured by
admixture of essences and the like.

COMPLETE SPECIFICATION.
An Improved Tollet and Nursery Powder.
I, HUGO WALDEMAR LANGBECK of No. 2 Claremont Villas, Loughton, in the
County of Essex, Analytical 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:
The healing and soothing qualities of woolfat as well as its quick absorption by the
skin are greatly improved when it is purified, that is to say deprived of free fatty acids
present in the fat when obtained from wool-washing water by means of acids. It is
also known that powders in general use such as so called "violet powder" and Fuller's
earth possess a great absorbing and soothing power.
According to my invention I combine these substances, thereby producing a com-
pound which possesses the good qualities of both.
Violet powder generally consists of perfumed starch powder, or starch powder and
wheat flour, sometimes also with an addition of French chalk or precipitated carbonate
of lime etc.
In order to produce a perfect toilet or nursery powder containing woolfat I proceed
as follows:-
Purified woolfat is slightly warmed and mixed with an absorbent substance, such as
carbonate of lime, gypsum, Fuller's earth or by preference white clay previously
reduced to impalpable powder, and known as kaolin, either by rubbing and kneading
the said mixture in a mortar or other suitable vessel, or better in a kneading and
mixing machine such as Pfleiderer's, for instance. By this means I can incorporate
up to 20 p.c. of purified woolfat with kaolin without the latter losing its powdery
appearance.
One part of the so prepared powder is then mixed with from 1 to 4 parts of starch
powder or a mixture of starch powder and wheat flour and sufficient perfume, and the
mixture is then equal in appearance to well prepared ordinary violet powder, but
containing from 4 to 10 p.c. of woolfat. In using Fuller's earth powder, I proceed as
above without however the addition of kaolin, Fuller's earth itself being clay. The

page_text: proportion of woolfat is in this case also from 5 to 10 p.c. For some special purposes
I mix one part of purified woolfat with from 5 to 10 or 20 parts of kaolin or Fuller's
earth powder or a mixture of both, with or without the addition of other absorbent
powders such as carbonate of lime, gypsum etc., and I incorporate therewith either
carbolic, salicylic or boric acid, iodoform, perchloride of mercury or other substances
having a disinfecting or soothing quality. In the case of carbolic, boric, salicycle
acid, iodoform I use a percentage of from 1 to 4; in the case of perchloride of mercury
I prefer 1 part in from 1000 to 10000 parts of powder.
As woolfat varies somewhat in its consistency, containing sometimes more cholesterine
and in consequence being harder, I in such cases melt the woolfat with from 10 to
30 p.c. of vaseline or lard previous to its being mixed with powder thus rendering it
softer and more suitable for certain applications.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An improved manufacture of toilet aud nursery powders consisting of the
admixture of woolfat or preparations thereof with absorbent pulverulent material, with
or without the addition of other substances substantially as set forth.
2. In the manufacture of toilet and nursery powders referred to in the preceding
claim, mixing the woolfat first with carbonate of lime, kaolin, Fuller's earth or other
absorbent powders of a similar nature or mixtures thereof, and then adding to this
mixture starch powder or farina with or without perfumes, substantially as herein
described.
