Description

Verfahren zur Einarbeitung antimikrobieller Produkte in Seifenmassen Process for incorporation of antimicrobial products in soap masses
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Konzentraten antimikrobieller Wirkstoffe, die Konzentrate selbst sowie ihre Verwendung zur Herstellung fester, flüssiger oder pastöser Körperreinigungsmittel, wie insbesondere Seifen.The present invention relates to a process for the preparation of concentrates of antimicrobial agents, the concentrates themselves and their use for the preparation of solid, liquid or pasty body cleansing compositions, in particular soaps.
Feste, flüssige oder pastöse Reinigungsmittel, wie insbesondere Seifen, enthalten Substanzen wie zum Beispiel Alkalisalze gesättigter oder ungesättigter Fettsäuren, die von Mikroorganismen leicht zersetzt werden können. Dabei entstehen Abbauprodukte, die die Reinigungswirkung vermindern und häufig eine unerwünschte Geruchsänderung herbeiführen.Solid, liquid or pasty detergents, in particular soaps, contain substances such as alkali salts of saturated or unsaturated fatty acids, which can easily be decomposed by microorganisms. This results in degradation products that reduce the cleaning effect and often cause an undesirable odor change.
Daher und vor dem Hintergrund einer erwünschten antimikrobiellen Wirkung enthalten Körperreinigungsmittel typischerweise antimikrobielle Wirkstoffe.Therefore, and in the context of a desired antimicrobial effect, personal cleansers typically contain antimicrobial agents.
Beispielsweise erfolgt die Herstellung von Stückseifen so, dass in einem ersten Schritt Seifenpellets hergestellt werden, indem die nach der Verseifung des zugrundeliegenden Fetts oderFor example, the production of bar soaps is carried out so that in a first step soap pellets are prepared by the after saponification of the underlying fat or

In einem zweiten Schritt werden die Seifenpellets mit weiteren Additiven wie z.B Duftstoffen, Farbstoffen, Pigmenten, optischen Aufhellern, antimikrobiellen Wirkstoffen oder deodorierende Zusätzen vermischt und über geeigneteOil base soap, which usually has a water content of about 30 to 40 wt .-%, with additives such.

Problematisch beim vorstehend beschriebenen Prozeß ist die Tatsache, daß eine homogene Einarbeitung der üblicherweise verwendeten antimikrobiellen Wirkstoffe aufgrund ihrer pulverfÖrmigen Konsistenz schwierig aber erforderlich ist, um eine gleichmäßige Wirkung im gesamten Produkt zu erreichen, einen sandigen Griff des Endproduktes jedoch zu vermeiden.A problem in the process described above is the fact that a homogeneous incorporation of the commonly used antimicrobial agents due to their powdery consistency is difficult but necessary to achieve a uniform effect throughout the product, however, to avoid a sandy grip of the final product.
Häufig verwendete antimikrobielle Wirkstoffe sind dabei beispielsweise N-(4-Chlorphenyl)-N'- (3,4-dichlorphenyl)-harnstoff (auch als Trichlorcarbanilid oder TCC bezeichnet), TriclosanFrequently used antimicrobial agents are, for example, N- (4-chlorophenyl) -N'- (3,4-dichlorophenyl) urea (also called trichlorocarbanilide or TCC), triclosan
(TCS) sowie verschiedene Parabene.(TCS) as well as various parabens.
Um eine im Wesentlichen homogene Verteilung der in der Regel in Wasser nahezu unlöslichen und in gängigen Tensiden schwerlöslichen antimikrobiellen Wirkstoffe im Produkt zu bewerkstelligen werden bei der Herstellung von Seifen üblicherweise sogenannte Slurries hergestellt, die der festen Seifengrundlage (auch Seifennudel genannt), die typischerweise über ein Schneckengetriebe gefordert wird, über Dosierpumpen kontinuierlich zugegeben werden. Diese Slurries bestehen üblicherweise zu bis zu 99 Gew.-% aus Parfümöl, Farbstoffen oder Farbstoffpräparationen und, sofern erforderlich, meist flüssigen, parfümlöslichen weiteren Bestandteilen zur Verbesserung derIn order to accomplish a substantially homogeneous distribution of the generally in water almost insoluble and sparingly soluble in common surfactants antimicrobial agents in the product In the production of soaps, so-called slurries are usually prepared, which are added continuously to the solid soap base (also called soap noodle), which is typically required via a worm gear, via metering pumps. These slurries are usually up to 99 wt .-% of perfume oil, dyes or dye preparations and, if necessary, usually liquid, perfume-soluble other ingredients to improve the
Anwendungstechnik, Dermatologie oder Toxikologie. Aufgrund der Restriktionen durch gesetzliche Auflagen sind dem Einsatz von Lösungsmitteln, Lösungsvermittlern, Emulgatoren oder speziellen Tensiden äußerst enge Grenzen gesetzt und würden weiterhin noch einen hohen verfahrenstechnischen Aufwand erfordern. Die Zugabe fester Inhaltsstoffe ist nach obigem Verfahren auf eine Einsatzmenge von in der Summe max. ca. 1 Gew.-% begrenzt. In der Summe bedeutet dabei, dass häufig noch weitere feste, wasserunlösliche Stoffe zugegeben werden und diese nur durch intensives Rühren im Slurry homogen verteilt werden können. Sollen größere Mengen der wasserunlöslichen Stoffe zudosiert werden, bietet sich die Möglichkeit der Feststoffeinwaage über Dosierschnecke, oder Bandwaage an. Hierbei tritt jedoch die vorgenannte Staubproblematik auf.Application engineering, dermatology or toxicology. Due to the restrictions imposed by legal requirements, the use of solvents, solubilizers, emulsifiers or special surfactants are extremely narrow limits and would still require a high procedural effort. The addition of solid ingredients is according to the above method to a use amount of a total of max. about 1 wt .-% limited. In sum, this means that often more solid, water-insoluble substances are added and they can be distributed homogeneously only in the slurry by intensive stirring. If larger quantities of the water-insoluble substances are to be added, the possibility of solids weighing via a dosing screw or belt scale is available. In this case, however, the aforementioned dust problem occurs.
Eine weitere Möglichkeit der Zugabe der in der Regel in Wasser nahezu unlöslichen und in gängigen Tensiden schwerlöslichen antimikrobiellen Wirkstoffe besteht über den Einsatz von Mischern, wie zum Beispiel Knetern, Z-Mixern oder ähnlichen Vorrichtungen mit geeigneter Austragsvorrichtung. Die Seifennudel wird bei diesem Verfahren vorgelegt, alle erforderlichen weiteren Rezepturbestandteile in der Lieferform zugegeben und bei Raumtemperatur bzw. Kühlung homogen vermischt. Mit Hilfe dieses Verfahrens kann man, ohne Zugabe weiterer Lösungsmittel, bis zu 15 Gew.-% fester oder pastöser Bestandteile der Seifennudel hinzufügen. Durch den daraus resultierenden Chargenbetrieb mit hohem Zeit- und Personalaufwand wird diese Verfahrensweise jedoch unwirtschaftlich, weiterhin wird das Problem der auftretenden Staubentwicklung nicht gelöst.Another possibility for adding the antimicrobial active ingredients, which are generally insoluble in water and sparingly soluble in common surfactants, is the use of mixers, such as kneaders, Z mixers or similar devices with a suitable discharge device. The soap noodle is presented in this process, added all the necessary additional formulation ingredients in the form and homogeneously mixed at room temperature or cooling. With the aid of this process, it is possible to add up to 15% by weight of solid or pasty constituents of the soap noodle without the addition of further solvents. Due to the resulting batch operation with high time and personnel expenses, however, this procedure is uneconomical, furthermore, the problem of dust formation occurring is not resolved.
Es bestand daher das Bedürfnis ein Verfahren bereitzustellen, das die homogene Einarbeitung eines antimikrobiellen Wirkstoffes in feste, flüssige oder pastöse Reinigungsmittel, wie insbesondere Seifen ermöglicht.There was therefore a need to provide a method which allows the homogeneous incorporation of an antimicrobial agent in solid, liquid or pasty detergents, in particular soaps.
Es wurde nun ein Verfahren zur Herstellung von Körperreinigungsmitteln, wie insbesondere Seifen gefunden, das dadurch gekennzeichnet ist, dass erfindungsgemäße Konzentrate mit einer Körperreinigungsmittelbasis vermischt werden, so dass der Gehalt an einem oder mehreren antimikrobiellen Wirkstoffen in den Körperreinigungsmitteln insgesamt 0,05 bis 5 Gew.-%, vorzugsweise 0,05 bis 1,5 Gew.-% beträgt. Vorzugsweise sind die Körperreinigungsmittel flüssig, pastös oder fest, besonders bevorzugt pastös oder festThere has now been found a process for the production of personal cleansing compositions, in particular soaps, which are characterized in that concentrates according to the invention are mixed with a body cleanser base, so that the content of one or more antimicrobial active substances in the body cleansing agents totals 0.05 to 5 wt. -% preferably 0.05 to 1.5 wt .-% is. Preferably, the body cleansing agents are liquid, pasty or solid, more preferably pasty or solid

Besonderer Vorteil der erfindungsgemäßen Konzentrate ist, dass Sie als leicht handhabbare Komponente in den üblichen Prozess der Seifenherstellung integrierbar sind, und insbesondere die im Stand der Technik geschilderten Probleme der homogenen Verteilung, des Staubverhaltens und unerwünschten Hilfsmitteln im Endprodukt erheblich reduzieren.A particular advantage of the concentrates according to the invention is that they can be integrated as easily manageable component in the usual process of soap production, and in particular significantly reduce the problems described in the prior art of homogeneous distribution, dust behavior and undesirable aids in the final product.
Des Weiteren ermöglicht die erfindungsgemäße Herstellung von Reinigungsmitteln die aufwändige Vorbehandlung der zugesetzten antimikrobiellen Wirkstoffe, wie z.B. Lösen und Anpasten gegebenenfalls bei höherer Temperatur. Dadurch wird weiterhin die Bildung von Neben- oder Abbauprodukten minimiert. Furthermore, the preparation according to the invention of cleaning agents allows the elaborate pretreatment of the added antimicrobial active ingredients, such as, for example, dissolution and pasting, optionally at elevated temperature. This further minimizes the formation of by-products or degradation products.
