Description

Die Erfindung betrifft ein Enthaarungsmittel gemäß The invention relates to a depilatory agent according to

dem Oberbegriff des Patentanspruchs 1.the preamble of claim 1.

Enthaarungsmittel oder Depilatorien sind Präparate, die meist in Cremes eingearbeitete Chemikalien enthalten, die ohne Hautschädigungen Haare von verschiedenen Körperstellen entfernen sollen. Neben oxidierend wirkenden Depilatorien sind vor allem solche, die die Cystinbrücken der Keratine durch Reduktion lösen, gebräuchlich. Depilatories or depilatories are preparations that are mostly used in Creams contain incorporated chemicals that remove hair from skin without damaging the skin should remove from different parts of the body. In addition to oxidizing depilatories are mainly those that break the cystine bridges in keratins through reduction, common.

Frühere Präparate der erstgenannten Art enthielten in der Regel alkalisch reagierende zersetzliche Sulfide oder Hydrogensulfide des Natriums, Calciums, Bariums oder Strontiums. Die Alkalien tragen zur Quellung des Keratins bei und die direkt oder nach erfolgter Hydrolyse abgespaltenen SH-Ionen bewirken die eigentliche Keratolyse.Earlier preparations of the first-mentioned type usually contained alkaline reactive decomposable sulfides or hydrogen sulfides of sodium, calcium, barium or strontiums. The alkalis contribute to the swelling of the keratin and those directly or SH ions split off after hydrolysis cause the actual keratolysis.

Da die Alkali- und Erdalkali-Schwefelverbindungen Schwefelwasserstoff entwickeln, der mit Geruchsstoffen nur unvollkommen überdeckt werden kann, verwendet man heute vorwiegend Calcium- und Strontiumsalze der Thioglykolsäure und ihrer Homologen, die meist in Kombination mit hautpflegenden Mitteln verwendet werden. As the alkali and alkaline earth sulfur compounds are hydrogen sulfide develop that can only be imperfectly masked with odorous substances today mainly calcium and strontium salts of thioglycolic acid and its homologues, which are mostly used in combination with skin care products.

Es ist bekannt, daß fettartige und fettige Materialien in Enthaarungsmitteln vermieden oder auf ein Minimum beschränkt werden müssen. Solche Materialien überziehen den Haarschaft und beeinträchtigen somit den Kontakt mit den wässrigen Thioglykolsäuresalzen. Weiterhin verhindern fettartige Materialien die Benetzung des Haarschaftes und führen zu verlängerten Enthaarungszeiten. It is known that fatty and fatty materials are used in depilatories must be avoided or kept to a minimum. Cover such materials the hair shaft and thus impair contact with the aqueous thioglycolic acid salts. Furthermore, fatty materials prevent wetting of the hair shaft and lead to extended depilation times.

Die gegenwärtig oder bisher verfügbaren Depilatorien weisen jedoch im allgemeinen erhebliche Nachteile auf, d.h. sie berühren aufgrund ihrer Zusammensetzung den Haarschaft nicht effektiv, was zu längeren Enthaarungszeiten führt. Der Verbraucher ist gezwungen eine größere Menge Enthaarungscreme oder -schaum für die gleiche Fläche, die enthaart werden soll zu verwenden. Generell wird unterschieden zwischen mechanisch wirkenden und chemisch wirkenden Mitteln, wobei letztere in Creme- oder Aerosolform vorliegen. Infolge ihrer Zusammensetzung sind letztere nicht unbegrenzt haltbar. However, the currently or hitherto available depilatories show generally have considerable disadvantages, i.e. they affect due to their composition not the hair shaft effective, resulting in longer depilation times leads. The consumer is forced to use a larger amount of depilatory cream or foam to be used for the same area to be depilated. A distinction is generally made between mechanically acting and chemically acting agents, the latter in In cream or aerosol form. Due to their composition, the latter are not Shelf life indefinitely.

Die Aufgabe der Erfindung besteht nun darin, ein Enthaarungsmittel auf chemischer Basis von praktisch unbegrenzter Haltbarkeit und einer besonderen Effektivität vorzuschlagen, durch das die Enthaarungszeiten erheblich verkürzt werden können. The object of the invention is now to provide a depilatory agent on a chemical basis of practically unlimited shelf life and a special one To suggest effectiveness that will significantly reduce depilation times can.

Die Lösung dieser Aufgabe wird durch die im Kennzeichen des Patentanspruchs 1 beschriebene technische Lehre vermittelt. The solution to this problem is provided in the characterizing part of the claim 1 conveyed the technical teaching described.

Das erfindungsgemäße Enthaarungsmittel setzt sich aus 3-10 Gew.-% eines Thioglykolsäuresalzes, 2-30 Gew.-% Calciumsalzen und einem Restgehalt an Stärke zusammen, wobei der pH-Wert der Zusammensetzung zwischen 11,5 und 12,5 liegt. The depilatory agent according to the invention is composed of 3-10% by weight a thioglycolic acid salt, 2-30% by weight calcium salts and a residual content of starch together, the pH of the composition being between 11.5 and 12.5.

Das Mittel hat eine pulvrige Konsistenz, ist absolut fettfrei und wird erst vor der Anwendung mit Wasser zu einem Brei angerührt und dünnflüssig aufgetragen, wobei auf diese Weise der Haar schaft effektiver berührt und dadurch eine schnelle Depilationswirkung erreicht werden.The agent has a powdery consistency, is absolutely fat-free and is mixed with water to a paste and applied thinly before use, In this way, the hair shaft is touched more effectively and therefore quick Depilation effect can be achieved.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels beschrieben: Es wurde eine die folgenden Bestandteile enthaltende Zusammensetzung in den angegebenen Gewichtsprozenten hergestellt: Gewichtsteile Thioglykolsäure 50% 3 - 10 Calciumhydroxid (pharmazeut. Standard) 2 - 4 Calciumcarbonat 26 - 28 Stärke zu 100 Die Thioglykolsäure und das Calciumhydroxid wurden in einen Kessel aus Polyäthylen gegeben und gerührt. The invention is explained below on the basis of an exemplary embodiment described: It became one containing the following ingredients Composition produced in the specified percentages by weight: parts by weight Thioglycolic acid 50% 3 - 10 calcium hydroxide (pharmaceutical standard) 2 - 4 calcium carbonate 26 - 28 strength to 100 The thioglycolic acid and the calcium hydroxide were in one Given a polyethylene kettle and stirred.

Nachdem das Gemisch gut gemischt war, wurde Calciumcarbonat zugesetzt und gut gemischt und dann Stärke zugesetzt.After the mixture was well mixed, calcium carbonate was added and mixed well and then added starch.

Angaben: pH-Wert 11,5 - 12 Ein Test inbezug auf die Enthaarungszeit und die Hautreizung wurde mit dem erhaltenen Depilator-Pulver wie folgt ausgeführt: Enthaarungspulver wurde mit lauwarmem Wasser zu Brei gemiscltund auf den Beinen einer Gruppe von vier Frauen aufgetragen.Information: pH value 11.5 - 12 A test in relation to the depilation time and skin irritation was carried out with the resulting depilator powder as follows: Depilatory powder was mixed into a pulp with lukewarm water and placed on the legs applied to a group of four women.

Gleichzeitig wurde eine andere Enthaarungscreme auf den Beinen der gleichen Gruppe von vier Frauen aufgetragen. At the same time, another depilatory cream was put on the legs same group of four women applied.

Durch Beobachten der Schrumpfwirkung des behandelten Stoppelhaares kann der Endpunkt der Depilationszeit vorausgesehen werden. Alle 30 sec. vor dem erwarteten Endpunkt wird mit einem feuchten Tuch über einen Abschnitt der behandelten Fläche gerieben. Wenn das Haar frei wegwischbar ist, so ist dies die Depilationszeit.By observing the shrinking effect of the treated stubble the end point of the depilation period can be foreseen. Every 30 seconds before the expected endpoint is treated with a damp cloth over a section of the Rubbed surface. If the hair can be freely wiped away, this is the depilation time.

Depilationszeiten: durchschnittl. Depilationszeit a. beim erfindungsgemäßen 5 Minuten Depilator-Pulver b. bei herkömmlicher 9,5 Minuten Enthaarungscreme Um die Haut auf Reizung zu untersuchen, wurde ein Teil des Enthaarungsmittels 15 Minuten auf den Beinen einer Gruppe von vier Frauen belassen, worauf die Haut am Endpunkt der Depilationszeit auf Reizung untersucht wurde. Das Enthaarungsmittel wurde dann entfernt und die Haut nach einer Stunde erneut geprüft. Die Ergebnisse des Reizungsversuchs wurden wie folgt bewertet: keine Reaktion.Depilation times: avg. Depilation time a. in the invention 5 minutes depilator powder b. with conventional 9.5 minutes depilatory cream Um Examining the skin for irritation became part of the depilatory for 15 minutes Left on the legs of a group of four women, whereupon the skin at the end point the depilation time was examined for irritation. The depilatory was then removed and the skin checked again after an hour. The results of the irritation test were rated as follows: no response.

Das Enthaarungsmittel gemäß Erfindung zeigte eine durchschnittliche Reizbewertung von null. The depilatory composition according to the invention showed an average Stimulus rating of zero.
