Description

The i.nvention rela-~es to hair cosrnet.ic
p.~eparations, such as ha.ir ~onics, rest.orers, shampoos an~
the like.
Hair cosmetic preparations, such as hair tonics,
restorers, shampoos and the like for looking after ~he hair
and the scalp have long been known and a very lar~e number
of different compositions exist for these (cf. e.g.
Taschenbuch der ~odernen Parfumerie und Kosmetik, Hugo
Janistyn, 3rd edition, 1966). However, despite numerous
attempts, the hair gro~th-aiding action of these agents has
not as yet been satisfactory. It has now surprisingly been
found that such agents can be given a good hair
growth aiding action if specific extracts are added
thereto.
The invention therefore relates to hair cosmetic
- preparations containing a solvent extracted extract
obtairled from at least one of the group consistinq of olivs
stones, pomegranate pips, seeds of the fruit of
Glossostemon bruguierl, and tubers of Pueraria mirifica, saic
extract having been obtained by extracti.ng with a polar
organic solvent.
The preparation of the extracts to be used
according to the invention takes place through conventional
extraction of olive stones, pomegranate pips lPunica
granatum), seeds of the fruit of Glossostemon bruguieri,
and ~ubers of Pueraria mi.rlfica ~a type of legume). For
example defatted or non-defatted ol.ive stones are extracted
with suitable polar organic solvents such as methanol,
.,.~ n propanol, isopropanol~ glacial acetic

acid or mixtures thereof and f`rom these fluidl Spissum or
dried extrac-ts are prepared. These are then added to the
ha-ir cosmetic preparation. Conventionally, the olive
stones used in this mannel^ are ground prior -to extractlon.
The pits can be grollrld In a cross beater mill to particle
size of 0.5 to 1 mm in diameter.
The most important of the usual extraction
procedures that can be used are: maceration, turbulent
extraction~ counter-current or counter-flow extraction,
percolation5 repercolation, evaculation (extraction under
reduced pressure)~ and dicoalation. All of these
procedures are described in Hagers Handbuch der
Pharmazeutischen Praxisg fourth edition, vol. 7, Springer
Verlag, Berlin Heide1ber~, 1971.
For the preparation o-F the hair tonics the
aForementioned vegetable constituents, such as ground olive
stones, are preferably extracted with isopropanol or
ethanol, so that optionally after removing excess
extractant, fluid extracts are obtained and these can be
immediately used as a constituent of hair tonics. Normally
such hair tonics contain further known substances which
have a beneficial action on the hair or scalp.
In the preparation of the hair tonics according
to the invention in general 10 to 25 vol.% and in
part-icular 20 vol.% of fluid extract are used~ The solids
content o~ the fluid extract is generally approximately 6%,

'I'herefore, w'hen using Spissum or dry extract smaLler
quan-tities, e.g. 4 to 6% of dry extrac-t are used in the
pr~paration of the hair tonics. It is pointed out in this
connection that a fluid extract, is generally an extract in
which the ratio of the substance to be extracted to th~
extxae~ant is 1:1.
Extracts from olive pits can be prepared by
percolation using isopropanol at room temperatures over a
time period of seven days. In using this procedure, about
1~2 Kg of isopropanol is used for each kilogram of pits.
As indica~ed usllally the weight ratio or a fluid extract
is 1:1 but a slight excess of isopropanol is required
because the pits absorb some ~olvent. It is assu~ed that
phytosterines are extracted by this process but no exact
information on the chemical composition and structure of
these compounds is available at present.
The hair cosmetic preparations according to the
invention have proved surprisingly effective in assisting
hair growth, as is demonstrated by means of the following
example.
Example
A fluid extract is prepared by extracting ground
olive stone~ with isopropanol. 12 Kg of the fluid extract
obtained after removing ~xcess propanol (1:1), 200 g of
methanol, 200 9 of pantothenyl alcohol and 800 g of perfume
are then topped up to 100 litres with a liquid comprising
50 vol.% of isopropanol and 50 vol.~ water. The thus
prepared hair tonic was then tested on twenty p~rsons

q~
5 ---
teen women and five men of different age).
It was fo~nd that the hair tonic had a very good
compatability. l~e 24 hour ~alue of the hair tonic gave a
~+ positive result in one case, a ~ positive result in four
S cases, a weak positive reaction in four further cases and
no reaetion in the remaining ten cases. In the 48 hour
test the reactions were naturally retrogressive, so that in
only one case was there a ~+ reaction, in one case a +
reaction and in two cases limited positive reactions. The
remainder of the fifteen patients were completely negative
in 48 1nour tests~
This result must be considered excellent for a
hair tonic because a certain stimulating reaction is
desired. Thus, the hair tonic according to the invention,
compared with the numerous commercially available
cosmetics~ is very suitable as a hair cosmetic
preparation.
It was also found that in the case of several
patients the product not only strengthened the hair and
stopped the exis~ing falling out of hair, bu~ also led to
new hair grQwth~ The further tests carried out on the
bas.is of these observations revealed that the hair tonic
according to the invention has a marked grow~h~aiding
activn.
