Beschreibung description
Verwendung von hohen Elektrolytkonzentrationen in kosmetischen ReinigungsmittelnUse of high electrolyte concentrations in cosmetic cleaning agents
Die vorliegende Erfindung betrifft kosmetische Reini¬ gungsmittel .The present invention relates to cosmetic cleaning agents.
Derartige Mittel sind an sich bekannt. Es handelt sich dabei im wesentlichen um oberflächenaktive Substanzen oder Stoffgemische, die dem Verbraucher in verschiedenen Zube¬ reitungen angeboten werden.Such means are known per se. These are essentially surface-active substances or mixtures of substances which are offered to the consumer in various preparations.
Zubereitungen dieser Art sind beispielsweise Schaum- und Duschbäder, feste und flüssige Seifen oder sogenannte "Syndets" (synthetische Detergentien ) , Shampoos, Hand¬ waschpasten, Intimwaschmittel, spezielle Reinigungsmittel für Kleinkinder und dergleichen.Preparations of this type are, for example, foam and shower baths, solid and liquid soaps or so-called "syndets" (synthetic detergents), shampoos, hand wash pastes, intimate detergents, special cleaning agents for small children and the like.
Oberflächenaktive Stoffe - am bekanntesten die Alkalisalze der höheren Fettsäuren, also die klassischen "Seifen" - sind amphiphile Stoffe, die organische unpolare Substanzen in Wasser emulgieren können.Surface-active substances - best known are the alkali salts of higher fatty acids, ie the classic "soaps" - are amphiphilic substances that can emulsify organic non-polar substances in water.
Diese Stoffe schwemmen nicht nur Schmutz von Haut und Haaren, sie reizen, je nach Wahl des Tensids oder des Tensidgemisches , Haut und Schleimhäute mehr oder minder stark . Das gebräuchlichste Tensid für kosmetische Zusammenset¬ zungen ist das Natriu laurylethersulfat . Obwohl es gute Waschkraft besitzt und einigermaßen haut- und schleimhaut¬ verträglich ist, sollten empfindliche Personen den häufi¬ gen Kontakt damit meiden.These substances not only wash away dirt from the skin and hair, they irritate the skin and mucous membranes to a greater or lesser extent, depending on the choice of surfactant or mixture of surfactants. The most common surfactant for cosmetic compositions is sodium lauryl ether sulfate. Although it has good washing power and is somewhat compatible with the skin and mucous membrane, sensitive people should avoid frequent contact with it.
Es ist zwar eine große Zahl recht milder Tenside erhält¬ lich, jedoch sind die Tenside des Standes der Technik entweder mild, reinigen aber schlecht, oder aber sie reinigen gut, reizen jedoch Haut oder Schleimhäute.Although a large number of very mild surfactants are available, the surfactants of the prior art are either mild, but clean poorly, or they clean well, but irritate skin or mucous membranes.
Es war somit die Aufgabe der vorliegenden Erfindung, den Mißständen des Standes der Technik abzuhelfen.It was therefore the object of the present invention to remedy the shortcomings of the prior art.
Erfindungsgemäß wird diese Aufgabe gelöst durch die Ver¬ wendung von Elektrolyten in wäßrigen kosmetischen Reini¬ gungsmitteln oder für die wäßrige Reinigung bestimmten wasserarmen oder wasserfreien Reinigungsmittelkonzentra¬ ten, wobei der oder die Elektrolyte in höheren Konzentra¬ tionen als 6 Gew.-%, bezogen auf das Gesamtgewicht der Reinigungsmittel bzw. der Konzentrate, vorliegen, zur Be¬ kämpfung und Prophylaxe von Dermatosen, insbesondere Kopf¬ schuppen, sowie zur Verhinderung der Penetration der in den Reinigungsmitteln enthaltenen grenzflächenaktiven Sub¬ stanzen und/oder anderer in diesen Reinigungsmitteln ent¬ haltenen Substanzen in die äußeren Hautschichten.According to the invention, this object is achieved by the use of electrolytes in aqueous cosmetic cleaning agents or water-poor or water-free cleaning agent concentrations intended for aqueous cleaning, the electrolyte (s) being present in higher concentrations than 6% by weight, based on the total weight of the cleaning agents or the concentrates are present, for combating and prophylaxis of dermatoses, in particular dandruff, and for preventing the penetration of the surface-active substances contained in the cleaning agents and / or other substances contained in these cleaning agents into the outer layers of the skin.
Seit langem ist die Verwendung von Kochsalz und anderen Elektrolyten in wäßrigen Reingungsmitteln bekannt. In solchen Formulierungen dienen sie im Zusammenspiel mit bestimmten grenzflächenaktiven Substanzen als Konsistenz¬ geber. In solchen Zusammensetzungen betragen die Elektro¬ lytkonzentrationen im allgemeinen etwa 1 - 3 Gew.-%.The use of table salt and other electrolytes in aqueous cleaning agents has been known for a long time. In such formulations, they serve as a consistency agent in conjunction with certain surface-active substances. In such compositions, the electrolyte concentrations are generally about 1-3% by weight.
Ferner . eschreibt die EP-OS 0 447 519 die Verwendung was¬ serlöslicher, mit Tensiden ohne Ausfällung kompatibler Alkali-, Erdalkali- oder Aluminiumsalze anorganischer oder organischer Anionen in einer Menge von mindestens 2 Gew.-%, vorzugsweise mindestens 5 Gew.-% (berechnet als wasserfreies Salz), zur Konservierung konservierungsmit¬ telfreier, flüssiger, wasserhaltiger Tensidsyste e, ent¬ haltend 2 - 50 Gew.-%, vorzugsweise 5 - 35 Gew.-% eines oder mehrerer Tenside.Furthermore. EP-OS 0 447 519 describes the use of water-soluble, compatible with surfactants without precipitation Alkali, alkaline earth or aluminum salts of inorganic or organic anions in an amount of at least 2% by weight, preferably at least 5% by weight (calculated as anhydrous salt), for preserving preservative-free, liquid, water-containing surfactant systems holding 2-50% by weight, preferably 5-35% by weight of one or more surfactants.
Pökelung und die damit verbundene konservierende Wirkung sind seit dem Altertum bekannt.Pickling and the associated preservative effect have been known since ancient times.
In Kenntnis der letzteren Schrift, die, was diesen Sach¬ verhalt angeht, nicht über eine Bestätigung der konservie¬ renden Wirkung hoher Salzkonzentrationen hinausgeht, wäre der Fachmann zu dem Schluß verleitet worden, daß Elektro- lyte in höherer Konzentration, nämlich durch ihre os oti- sche Wirkung, biozide Eigenschaften besitzen.Knowing the latter document, which does not go beyond confirming the preserving effect of high salt concentrations in this regard, the person skilled in the art would have been led to the conclusion that electrolytes in higher concentration, namely by their os oti - effective, biocidal properties.
Nicht selten nämlich ist mit antimikrobieller Wirkung, zu¬ mal, wenn sie nicht gegen spezielle ikrobielle biochemi¬ sche Vorgänge gerichtet ist, sondern auf für alle Lebewe¬ sen gleichbedeutende Wirkprinzipien beruht, eine schädli¬ che Wirkung auf den Menschen, bestenfalls Wirkungslosig- keit, verbunden.It is not uncommon for an antimicrobial effect, especially if it is not directed against specific microbial biochemical processes, but is based on principles of action that are equivalent for all living beings, is a harmful effect on humans, at best ineffectiveness, connected.
Folglich führt diese Schrift in die der vorliegenden Erfindung entgegengesetzte Richtung.Consequently, this document leads in the opposite direction to the present invention.
Erstaunlich und anhand des Standes der Technik nicht vor¬ auszusagen war, daß bei Befolgung der hiermit vorgelegten Lehre zum technischen Handeln Zubereitungen erhältlich sind, welche aus dermatologischer Sicht erheblich milder sind als die Zubereitungen des Standes der Technik.It was astonishing and could not be predicted from the state of the art that if the teaching of technical action presented here is followed, preparations are obtainable which, from a dermatological point of view, are considerably milder than the preparations of the prior art.
Weiterhin war erstaunlich, daß wahlweise klare oder perlglänzende Zubereitungen nahezu beliebiger Viskosität erhältlich sind, welche selbst unter außergewöhnlichen Bedingungen lagerstabil sind.It was also astonishing that either clear or pearlescent preparations of almost any viscosity are available which are stable in storage even under exceptional conditions.
Ferner war erstaunlich, daß Zubereitungen erhältlich sind, welche tägliche Hautwäsche erlauben, ohne daß es selbst bei als empfindlich geltenden Personen zu Austrocknung, Schuppenbildung, Juckreiz oder Entzündungserscheinungen kommt.It was also astonishing that preparations are available which allow daily skin washing without dehydration, dandruff, itching or signs of inflammation occurring even in persons considered sensitive.
Darüberhinaus war erstaunlich, daß Zubereitungen erhält¬ lich sind, welche selbst bei Verwendung sensibilisierender Inhaltsstoffe, vor allem Tenside, die sensibi lisierende oder gar allergisierende Wirkung solcher Inhaltsstoffe stark herabsetzen bzw. schon verhindern, daß solche In¬ haltsstoffe überhaupt durch die äußeren Hautschichten pe- netrieren .In addition, it was astonishing that preparations are available which, even when using sensitizing ingredients, especially surfactants, greatly reduce the sensitizing or even allergic effects of such ingredients or prevent such ingredients from penetrating through the outer skin layers at all. netrate.
Schließlich war erstaunlich, daß Zubereitungen erhältlich sind, welche selbst bei täglicher Anwendung die Neigung der Kopfhaut zu Kopfschuppen beträchtlich mindert.Finally, it was surprising that preparations are available which considerably reduce the tendency of the scalp to dandruff even with daily use.
Unter Elektrolyten im Sinne der vorliegenden Erfindung sind wasserlösliche Alkali-, Ammonium-, Erdalkali- (unter Einbeziehung des Magnesiums) und Zinksalze anorganischer Anionen und beliebige Gemische aus solchen Salzen zu verstehen, wobei gewährleistet sein muß, daß sich diese Salze durch pharmazeutische oder kosmetische Unbedenk¬ lichkeit auszeichnen.Electrolytes for the purposes of the present invention are water-soluble alkali, ammonium, alkaline earth (including magnesium) and zinc salts of inorganic anions and any mixtures of such salts, whereby it must be ensured that these salts are pharmaceutically or cosmetically safe ¬ distinction.
Die erfindungsgemäßen Anionen werden bevorzugt gewählt aus der Gruppe der Chloride, der Sulfate und Hydrogensulfate, der Phosphate, Hydrogenphosphate und der linearen und cyclischen 01 igophosphate sowie der Carbonate und Hydro- gencarbonate.The anions according to the invention are preferably selected from the group of the chlorides, the sulfates and hydrogen sulfates, the phosphates, hydrogen phosphates and the linear and cyclic oil phosphates as well as the carbonates and hydrogen carbonates.
Der bevorzugte Elektrolyt ist Kochsalz. Erfindungsgemäß enthalten die erfindungsgemäßen wäßrigen kosmetischen Reinigungsmittel oder für die wäßrige Reini¬ gung bestimmten wasserarmen oder wasserfreien Reinigungs¬ mittelkonzentrate 6 - 30 Gew.-%, auf das Gesamtgewicht der Zubereitung bezogen, eines oder mehrerer Elektrolyte, be¬ vorzugt Kochsalz.The preferred electrolyte is table salt.
