This invention relates to an improved hair
(Cl. 167-87)
In the treatment of human hair extreme cau
tion must always be exercised lest some substance
5 employed damage the hair, even though only to a
slight extent. Where the treatment is one, such
as the use of a rinse designed to leave a deposit
upon the hair, the reason for care is doubly ap
parent, for the longer the substanceremains on
10 the hair, the more opportunity is offered for
deleterious action. On the other hand, it is high
ly desirable that the deposited substance stay on
the hair a long time so that an excessive number
other salts which I have found useful are those
which are substantially neutral and in which the
negative radical is that of- a weak- organic acid
preferably containing four to six carbon atoms
and the positive radical is desirably ammonium,
though vsodium, potassium, ethyl amine, or the‘
like, may be used with some success.
By way of a speci?c example, I have found that
good results may be secured by mixing one part
of ammonium citrate with ?fteen parts of am- 10
monium tartrate and adding two grams of this
mixture to a quart of water._ Any suitable
quantity of a coloring material adapted to tint

I have found that while acids, such as tartaric
acid, when applied to the hair tend to hydrolyze
25 and attack the protein-like constituents of the
hair, in moist air, or when the hair is otherwise
wetted, salts of tartaric and citric acid, rather
surprisingly, are not only substantially inert with
respect to the air but also are capable of satis
30 fying the other varied and rather con?icting re ‘
quirements in an even superior manner. That is
to say, such neutral salts, notably ammonium
tartrate, do not, on the onev hand, injure the
texture of the hair appreciably or spoil a wave,
35 but do, on the other hand, remain ?xed in the
hair, apparently in the form of minute crystals ‘

may advantageously be marketed in a powdered
or crystalline form, so that the user may conven- 25

put up in solution or other form.
The coloring or tinting material which may be
employed is preferably not of such a character as
to permanently dye the hair but may be any suit- 30

ably soluble in water. The proportions of such _
coloring or tinting material which may be em

materials are known.
The terms and expressions which I have em

of such terms and expressions, of excluding any 40

More particularly, I have found that an admir

by employing a neutral salt of a weak organic
acid, preferably a water soluble ammonium salt

like, conforming to the indicated requirements,
may similarly be employed. vWhile I distinctly
prefer ammonium tartrate, it will be understood
that mixtures of such salts with or without tint

I claim:
I. A hair rinse comprising a solution-of a sub
stantially neutral salt of an organic hydroxy poly
carboxylic acid containing ‘four to six carbon
atoms adapted to become ?xed on the hair during
application thereof.
2. A hair rinse comprising a neutral salt of tar
taric acid adapted to become ?xed on the hair in
rinsing the same.
3. A hair "rinse comprising ammonium tartrate 55

and a tinting material adapted to become ilxed on
the hair in rinsing the same.
4“. A hair rinse comprising ammonium tartrate,
a relatively small amount of ammonium citrate,
and a‘ tinting material adapted to become ?xed on
the hair in rinsing the same. ‘
5. A hair rinse containing a substantially neu
tral salt of a weak organic acid of the group con
sistingvof tartaric; and citric acids adapted to be
10 come ?xed on the hair in rinsing the same.
6. A hair rinse comprising ammonium citrate
and _a tinting material adapted to become fixed on
the hair in rinsing the same.
7. A hair rinse comprising substantially iiiteen
parts oi’ ammonium tartrate andone partoi am- 5
monium citrate in solution in water, said solution
being adapted to deposit the‘ tartrate and citrate
on the hair in
the same.‘
