Improvements in Shampooing Lotions.
"I, GEORGE AUGUSTE LE ROY, Chemist, of 8, Rue Jeanne d'Arc, Rouen, in the
Republic of France, 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:-
For the purpose of removing grease from the hair, as well as from the head,
without destroying the curls or undulations of the hair, it has been customary
hitherto, to make use of petroleum ethers or spirits, as all the other more or less
hydrated preparations dry slowly, and, in moistening the hair, destroy the curls.
Unfortunately the petroleum ethers mentioned above, being highly inflammable
have caused numerous accidents, leading to their employment for this purpose
being prohibited by the public authorities.
I have succeeded in preparing shampooing lotions having the useful properties
of those with a base of petroleum ether, but without the same danger of inflam-
mability. With this object I have conceived the idea of employing chlorinated
compounds of carbon or of carbon and hydrogen (C" C and Cl C" H") used
separately or in combination. Amongst these compounds, I would specially
mention the tetrachloride of carbon (CC1) and the dichloride (C² Cl³).
.In order to reduce the cost price of these chlorinated carbon or chlorinated
hydrocarbon liquids, I add thereto less expensive although inflammable liquids,
such as petroleum ethers, anhydrous alcohols, etc., but, in such proportions that
the total resulting mixture is non-inflammable, or but slightly so, as compared
with shampooing lotions composed of petroleum ethers.
In order that the chlorinated carbon or chlorinated hydrocarbon may not cause
any unpleasant sensation to the scalp, upon the lotion being applied when the
scalp is very sensitive, I add to the lotions mentioned above, substances which
are slightly soothing or narcotic, such, for example, cocaine or its salts which at
once remove any disagreeable sensation. In order to prevent the inconvenience
of inhaling the vapours from the lotions during the employment of the latter,
and the necessity of ventilating the room for a length of time after the opera-
tion, I add to the lotions an anhydrous and inoffensive chemical compound, but
one with a peculiar and pungent odour, which, however, disappears after the
Jotion has been used, and leaves no disagreeable scent in the hair which has been
subjected to the cleansing process, for example, ammonia gas dissolved with
the chlorinated hydrocarbon liquid or through the medium of an anhydrous
alcohol, or other anhydrous medium added thereto.
"
وو
I prepare the shampooing lotions which I term undulantines as follows:-
I take 900 parts by volume of tetrachloride of carbon or of some other chloride
or hydrochloride of carbon that is non-inflammable, or only slightly so. To this
I add say 50-100-200 or even 300 parts, according to the degree of inflam-
mability desired, and even still larger quantities, of the inflammable and cleans-
ing hydrocarburet selected, such as spirits of petroleum or of benzine, to which
I add from 5 to 10 parts of an anhydrous alcohol, ethylic, methylic, or butylic.
I distil the mixture to dryness, at a sufficiently low temperature. To the dis-

page_text: tilled liquid I add from 0.5 to 0.05 parts by weight of crystallised cocaine or of
one of its salts, dissolved in the smallest possible quantity of anhydrous alcohol.
I further add traces of some colouring matter dissolved in anhydrous alcohol,
and of some kind of essence, for the purpose of perfuming the mixture. Beyond
this, but only if it be necessary that the undulantine" should act more effec-
tually as a regenerator of the capillary bulb, I add from 0.5 to 2 parts in weight
of pilocarpine of the dry extract of jaborandi, dissolved in anhydrous alcohol or
direct in the undulantine, or I may add cantharidine or the like. I finish
the preparation by more or less partially saturating with dried ammonia gas,
either the whole undulantine" liquid, or the quantities above mentioned of
alcohol put apart for this purpose, and only added to the "undulantine" after-
wards, and in which cocaine, the colouring matter, and the substances mentioned
above are dissolved. I reserve the right of dispensing with the ammonia gas,
when so preferred by the customer this being an addition which is made with
the object of giving the "undulantine" a peculiar odour, whilst virtually increas-
ing its cleansing effect.
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 preparation and use of shampooing lotions intended to remove grease
from the hair of the human head, to render the hair supple and aseptic and to
prevent it from falling off, such substances being rendered but slightly inflam-
mable or non-inflammable as compared with lotions having a base of petroleum
ether, being composed of chlorinated carbon or chlorinated hydrocarbon sub-
stances, especially tetrachlorido of carbon (C C14) or dichloride of carbon (C2 CH)
employed either individually, and separately, or in combination with one another,
or in combination with inflammable hydrocarbons, the mixture, if necessary,
having also an addition of (1), a narcotic substance; (2) of a substance possess-
ing a pungent odour; (3) and being suitably coloured and scented by means
employed in perfumery; (4) and, if necessary having an addition of substances
which regenerate the capillary bulb, such as pilocarpine, cantharidine, or the
like.
.
2. The improved shampooing lotion composed substantially as described and
prepared in the manner set forth.
