Description

Gebiet der ErfindungField of the invention

Die Erfindung befindet sich auf dem Gebiet der perlglänzenden Zubereitungen, speziell der Kosmetik und betrifft ein Verfahren zur Herstellung dieser Mittel auf kaltem Wege.The invention is in the field of pearlescent preparations, especially cosmetics and relates to a process for preparing these agents by the cold route.

Stand der TechnikState of the art

Der weich schimmemde Glanz von Perlen hat auf den Menschen schon seit Jahrtausenden eine besondere Faszination ausgeübt. Es ist daher kein Wunder, daß die Hersteller von kosmetischen Zubereitungen versuchen, ihren Produkten ein attraktives, wertvolles und gehaltvolles Erscheinungsbild zu verleihen. Der erste seit dem Mittelalter in der Kosmetik eingesetzte Perlglanz war eine perlglänzende Paste aus natürlichen Fischschuppen. Zu Anfang dieses Jahrhunderts entdeckte man, daß Wismutoxidchloride ebenfalls in der Lage sind, Perlglanz zu erzeugen. Für die moderne Kosmetik sind hingegen Perlglanzwachse, insbesondere vom Typ der Glycolmono- und -difettsäureester von Bedeutung, die überwiegend zur Erzeugung von Perlglanz in Haarshampoos und Duschgelen eingesetzt werden. Eine Übersicht zu modernen, perlglänzenden Formulierungen findet sich von A.Ansmann und R.Kawa in Parf.Kosm. 75, 578 (1994). The soft, shimmering sheen of pearls has exerted a special fascination on humans for millennia. It is therefore not surprising that the manufacturers of cosmetic preparations try to give their products an attractive, valuable and full-bodied appearance. The first pearlescent used in cosmetics since the Middle Ages was a pearlescent paste made from natural fish scales. At the beginning of this century, it was discovered that bismuth oxide chlorides are also capable of producing pearlescence. On the other hand, pearlescing waxes, in particular of the glycol mono- and di-fatty acid ester type, which are predominantly used to produce pearlescence in hair shampoos and shower gels, are of importance for modern cosmetics. An overview of modern, pearlescent formulations can be found by A.Ansmann and R.Kawa in Parf.Kosm. 75 , 578 (1994).

So sind beispielsweise aus den beiden deutschen Patentanmeldungen DE 3843572 A1 und DE 4103551 A1 (Henkel) Perlglanzkonzentrate in Form fließfähiger wäßriger Dispersionen bekannt, die 15 bis 40 Gew.-% perlglänzender Komponenten, 5 bis 55 Gew.-% Emulgatoren und 0,1 bis 5 bzw. 15 bis 40 Gew.-% Polyole enthalten. Bei den Perlglanzwachsen handelt es sich um acylierte Polyalkylenglycole, Monoalkanolamide, lineare, gesättigte Fettsäuren oder Ketosulfone. In den beiden Europäischen Patentschriften EP 0181773 B1 und EP 0285389 B1 (Procter & Gamble) werden Shampoozusammensetzungen vorgeschlagen, die Tenside, nicht-flüchtige Silicone und Perlglanzwachse enthalten. Gegenstand der Europäischen Patentanmeldung EP 0205922 A2 (Henkel) sind fließfähige Perlglanzkonzentrate, die 5 bis 15 Gew.-% acylierte Polyglycole, 1 bis 6 Gew.-% Fettsäuremonoethanolamide und 1 bis 5 Gew.-% nichtionische Emulgatoren enthalten. Gemäß der Lehre der Europäischen Patentschrift EP 0569843 B1 (Hoechst) lassen sich nichtionische, fließfähige Perlglanzdispersionen auch erhalten, indem man Mischungen von 5 bis 30 Gew.-% acylierten Polyglycolen und 0,1 bis 20 Gew.-% ausgewählten nichtionischen Tensiden herstellt. Aus der Europäischen Patentanmeldung EP 0581193 A2 (Hoechst) sind femer fließfähige, konservierungsmittelfreie Perlglanzdispersionen bekannt, die acylierte Polyglycolether, Betaine, Aniontenside und Glycerin enthalten. Schließlich wird in der Europäischen Patentanmeldung EP 0684302 A1 (Th.Goldschmidt) die Verwendung von Polyglycerinestem als Kristallisationshilfsmittel für die Herstellung von Perlglanzkonzentraten vorgeschlagen.The prior art knows a variety of formulations which impart the desired pearlescence to surfactants. Pearlescent concentrates in the form of flowable aqueous dispersions are known, for example, from German Patent Applications DE 3843572 A1 and DE 4103551 A1 (Henkel), which contain 15 to 40% by weight pearlescent components, 5 to 55% by weight emulsifiers and 0.1 to 5 or 15 to 40 wt .-% polyols. The pearlescent waxes are acylated polyalkylene glycols, monoalkanolamides, linear, saturated fatty acids or ketosulfones. The two European patents EP 0181773 B1 and EP 0285389 B1 (Procter & Gamble) propose shampoo compositions containing surfactants, non-volatile silicones and pearlescent waxes. The subject of European Patent Application EP 0205922 A2 (Henkel) are flowable pearlescent concentrates which contain 5 to 15% by weight of acylated polyglycols, 1 to 6% by weight of fatty acid monoethanolamides and 1 to 5% by weight of nonionic emulsifiers. According to the teaching of European Patent EP 0569843 B1 (Hoechst), nonionic, flowable pearlescent dispersions can also be obtained by preparing mixtures of 5 to 30% by weight of acylated polyglycols and 0.1 to 20% by weight of selected nonionic surfactants. European Patent Application EP 0581193 A2 (Hoechst) also discloses flowable, preservative-free pearlescent dispersions which contain acylated polyglycol ethers, betaines, anionic surfactants and glycerol. Finally, European Patent Application EP 0684302 A1 (Th.Goldschmidt) proposes the use of polyglycerol esters as crystallization auxiliaries for the preparation of pearlescent concentrates.

Handelsübliche Perlglanzwachse weisen Schmelzpunkte oberhalb von 80 °C auf und lassen sich daher nicht kalt in wäßrige Formulierungen einarbeiten. Der Fachmann ist daher gezwungen nach einem Heißverfahren zu arbeiten, d.h. die Wachse aufzuschmelzen und in der Formulierung langsam auskristallisieren zu lassen, wobei die Feinteiligkeit der Kristalle und damit die Brillanz des Perlglanzes eine Funktion der Abkühlgeschwindigkeit ist. Es ist daher sofort klar, daß solche Verfahren zeit- und energieaufwendig sind, so daß der Wunsch nach einer günstigeren Alternative besteht. In der Regel wird der Fachmann daher auf sogenannte Perlglanzkonzentrate ausweichen, bei denen es sich um mehr oder minder konzentrierte tensidische Zubereitungen handelt, die die Perlglanzwachse bereits in feinverteilter, d.h. perlglanzaktiver Form enthalten und durch Emulgatoren stabilisiert sind. Solche Perlglanzkonzentrate lassen sich zwar kalt weiterverarbeiten, doch wird das eigentliche Problem dadurch nicht gelöst, sondern nur auf die Stufe der Hersteller dieser Zwischenprodukte verlagert, da die Konzentrate ihrerseits natürlich wieder nur durch ein Heißverfahren zugänglich sind.Commercially available pearlescent waxes have melting points above 80 ° C and therefore can be do not mix cold into aqueous formulations. The skilled person is therefore forced to one Hot process to work, i. melt the waxes and slowly crystallize in the formulation let the fineness of the crystals and thus the brilliance of the pearlescent a Function of the cooling rate is. It is therefore immediately clear that such processes take time and energy are so that there is a desire for a cheaper alternative. Usually will the expert therefore to dodge so-called pearlescent concentrates, which are more or less concentrated surface-active preparations which already contain the pearlescent waxes in finely divided, i.e. pearlescent form and are stabilized by emulsifiers. Such pearlescent concentrates can be processed cold, but the actual problem is thereby not solved, but only shifted to the stage of the manufacturer of these intermediates, as the concentrates in turn, of course, are accessible only by a hot process again.

Die Aufgabe der vorliegenden Erfindung hat daher darin bestanden, ein Verfahren zur Verfügung zu stellen, welches die kalte Einarbeitung von Perlglanzwachsen in tensidische Zubereitungen - seien es Zwischenprodukte, wie z.B. Perlglanzkonzentrate oder Endformulierungen, wie z.B. Shampoos - gestattet. Gleichzeitig sollte durch den Kaltprozeß weder die Brillanz des Perlglanzes noch die Stabilität der Formulierungen negativ beeinflußt werden.The object of the present invention has therefore been to provide a method available which is the cold incorporation of pearlescent waxes into surfactant preparations - be it Intermediates, such as e.g. Pearlescent concentrates or final formulations, e.g. Shampoos - allowed. At the same time, neither the brilliance of the pearlescence nor the stability was due to the cold process the formulations are adversely affected.

Beschreibung der ErfindungDescription of the invention

Gegenstand der Erfindung ist ein Verfahren zur kalten Herstellung von perlglänzenden Tensidzubereitungen, bei dem man wäßrige Tensidlösungen vorlegt und bei Temperaturen im Bereich von 10 bis 45, vorzugsweise 15 bis 25 °C Mischungen aus Perlglanzwachsen und Polyolestem einrührt. The invention relates to a process for the cold preparation of pearlescent surfactant preparations, in which aqueous surfactant solutions are initially introduced and at temperatures in the range from 10 to 45, preferably 15 to 25 ° C mixtures of pearlescent waxes and Polyolestem stirred.

Überraschenderweise wurde gefunden, daß schon der Zusatz geringer Mengen von Polyolestem den Schmelzpunkt von Perlglanzwachsen so weit herabsetzt, daß ihre kalte (10 bis 25 °C) Einarbeitung in tensidische Formulierungen problemlos möglich wird. Unabhängig davon, ob es sich bei den Zubereitungen um Zwischenprodukte (z.B. Perlglanzkonzentrate) oder Endformulierungen für den Verbraucher (z.B. Shampoos, Geschirrspülmittel) handelt, weisen die Mittel einen brillanten Perlglanz auf, sind lagerstabil und erlauben auch die Einarbeitung schwierig zu formulierender Inhaltsstoffe, wie z.B. Silicon-öle. Die Erfindung schließt die Erkenntnis ein, daß auf diese Weise nicht nur perlglänzende Mittel hergestellt werden können, sondern - in Abhängigkeit des Wachstyps und des Emulgators - auch solche, die über eine intensive Weißtrübung verfügen.Surprisingly, it has been found that even the addition of small amounts of Polyolestem the Melting point of pearlescent wax so low that their cold (10 to 25 ° C) incorporation into Surfactant formulations is easily possible. Regardless of whether it is the preparations intermediate products (e.g., pearlescent concentrates) or final formulations for the consumer (e.g., shampoos, dishwashing detergent), the agents have brilliant pearlescence, are storage stable and also allow the incorporation of difficult-to-formulate ingredients, e.g. Silicone oils. The invention includes the recognition that not only pearlescent agents are produced in this way but, depending on the type of wax and the emulsifier, also those which have an intense white turbidity.

Als Perlglanzwachse (a8) kommen femer Fettether vorzugsweise der Formel (IX) in Frage, R16-O-R17    (IX) in der R16 und R17 unabhängig voneinander für Alkyl- und/oder Alkenylreste mit 1 bis 22 Kohlenstoffatomen stehen, mit der Maßgabe, daß sie in Summe mindestens 24 und vorzugsweise 32 bis 48 Kohlenstoffatome aufweisen. Fettether der genannten Art werden üblicherweise durch saure Kondensation der entsprechenden Fettalkohole hergestellt. Fettether mit besonders vorteilhaften Pertglanzeigenschaften werden durch Kondensation von Fettalkoholen mit 16 bis 22 Kohlenstoffatomen, wie beispielsweise Cetylalkohol, Cetearylalkohol, Stearylalkohol, Isostearylalkohol, Oleylalkohol, Behenylalkohol und/oder Erucylalkohol erhalten. Further preferred pearlescing waxes (a8) are fatty ethers of the formula (IX) R 16 -OR 17 (IX) in which R 16 and R 17 independently of one another are alkyl and / or alkenyl radicals having 1 to 22 carbon atoms, with the proviso that they have in total at least 24 and preferably 32 to 48 carbon atoms. Grease ethers of the type mentioned are usually prepared by acid condensation of the corresponding fatty alcohols. Fatty ethers having particularly advantageous perturbing properties are obtained by condensation of fatty alcohols having 16 to 22 carbon atoms, such as cetyl alcohol, cetearyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, behenyl alcohol and / or erucyl alcohol.

Als Komponente (a9) kommen weiterhin Fettcarbonate vorzugsweise der Formel (X) in Betracht, R18O-CO-OR19    (X) in der R18 und R19 unabhängig voneinander für Alkyl- und/oder Alkenylreste mit 1 bis 22 Kohlenstoffatomen stehen, mit der Maßgabe, daß sie in Summe mindestens 24 und vorzugsweise 32 bis 48 Kohlenstoffatome aufweisen. Die Stoffe werden erhalten, indem man beispielsweise Dimethyl- oder Diethylcarbonat mit den entsprechenden Fettalkoholen in an sich bekannter Weise umestert. Demzufolge können die Fettcarbonate symmetrisch oder unsymmetrisch aufgebaut sein. Vorzugsweise werden jedoch Carbonate eingesetzt, in denen R18 und R19 gleich sind und für Alkylreste mit 16 bis 22 Kohlenstoffatomen stehen. Besonders bevorzugt sind Umesterungsprodukte von Dimethyl- bzw. Diethylcarbonat mit Cetylalkohol, Cetearylalkohol, Stearylalkohol, Isostearylalkohol, Oleylalkohol, Behenylalkohol und/ oder Erucylalkohol in Form ihrer Mono- und Diester bzw. deren technischen Mischungen.Also suitable as component (a9) are fatty carbonates, preferably of the formula (X) , R 18 O-CO-OR 19 (X) in which R 18 and R 19 independently of one another are alkyl and / or alkenyl radicals having 1 to 22 carbon atoms, with the proviso that they have in total at least 24 and preferably 32 to 48 carbon atoms. The substances are obtained by, for example, transesterifying dimethyl or diethyl carbonate with the corresponding fatty alcohols in a manner known per se. As a result, the fatty carbonates can be symmetrical or asymmetrical. Preferably, however, carbonates are used in which R 18 and R 19 are the same and are alkyl radicals having 16 to 22 carbon atoms. Transesterification products of dimethyl or diethyl carbonate with cetyl alcohol, cetearyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, behenyl alcohol and / or erucyl alcohol in the form of their mono- and diesters or their technical mixtures are particularly preferred.

    Emulgatorenemulsifiers

    Wie schon ausgeführt, können die tensidischen Zubereitungen grundsätzlich alle Typen von Tensiden enthalten; deren Auswahl richtet sich allein nach dem gewünschten Anwendungsprofil für den Endverbrauch. In einer bevorzugten Ausführungsform der Erfindung handelt es sich bei den tendischen Zubereitungen jedoch um Perlglanzkonzentrate, also Zwischenprodukte. Hier ist die Auswahl der Tensidkomponente kritischer, da das anwendungstechnische Anforderungsprofil primär darin besteht, möglichst hohe Mengen des Perlglanzwachses dauerhaft zu stabilisieren und die Viskosität der Mittel dabei so niedrig zu halten, daß sie noch problemlos gepumpt und dosiert werden können. Für diesen Zweck kommen beispielsweise nichtionogene Tenside aus mindestens einer der folgenden Gruppen in Frage:

  • Anlagerungsprodukte von 2 bis 30 Mol Ethylenoxid und/ oder 0 bis 5 Mol Propylenoxid an lineare Fettalkohole mit 8 bis 22 C-Atomen, an Fettsäuren mit 12 bis 22 C-Atomen, an Alkylphenole mit 8 bis 15 C-Atomen in der Alkylgruppe sowie Alkylamine mit 8 bis 22 Kohlenstoffatomen im Alkylrest;

  • Wollwachsalkohole;
  • Polysiloxan-Polyalkyl-Polyether-Copolymere bzw. entsprechende Derivate;
  • Polyalkylenglycole sowie
  • Glycerincarbonat.
  • As already stated, the surfactant preparations may in principle contain all types of surfactants; their selection depends solely on the desired application profile for the end use. In a preferred embodiment of the invention, however, the tend preparations are pearlescent concentrates, ie intermediates. Here, the selection of the surfactant component is more critical, since the application requirement profile is primarily to permanently stabilize the highest possible levels of pearlescent wax and to keep the viscosity of the agent so low that they can still be easily pumped and dosed. Nonionic surfactants from at least one of the following groups, for example, are suitable for this purpose:
  • Addition products of 2 to 30 moles of ethylene oxide and / or 0 to 5 moles of propylene oxide to linear fatty alcohols having 8 to 22 carbon atoms, to fatty acids having 12 to 22 carbon atoms, to alkylphenols having 8 to 15 carbon atoms in the alkyl group and alkylamines with 8 to 22 carbon atoms in the alkyl radical;
  • Alkyl mono- and oligoglycosides having 8 to 22 carbon atoms in the alkyl radical and their ethoxylated analogs;

  • Polysiloxane-polyalkyl-polyether copolymers or corresponding derivatives;
  • Polyalkylene glycols as well
  • Glycerol carbonate.
  • Die Anlagerungsprodukte von Ethylenoxid und/oder von Propylenoxid an Fettalkohole, Fettsäuren, Alkylphenole oder an Ricinusöl stellen bekannte, im Handel erhältliche Produkte dar. Es handelt sich dabei um Homologengemische, deren mittlerer Alkoxylierungsgrad dem Verhältnis der Stoffmengen von Ethylenoxid und/ oder Propylenoxid und Substrat, mit denen die Anlagerungsreaktion durchgeführt wird, entspricht. C12/18-Fettsäuremono- und -diester von Anlagerungsprodukten von Ethylenoxid an Glycerin sind aus DE 2024051 PS als Rückfettungsmittel für kosmetische Zubereitungen bekannt. C8/18-Alkylmono- und -oligoglycoside, ihre Herstellung und ihre Verwendung sind aus dem Stand der Technik bekannt. Ihre Herstellung erfolgt insbesondere durch Umsetzung von Glucose oder Oligosacchariden mit primären Alkoholen mit 8 bis 18 C-Atomen. Bezüglich des Glycosidrestes gilt, daß sowohl Monoglycoside, bei denen ein cyclischer Zuckerrest glycosidisch an den Fettalkohol gebunden ist, als auch oligomere Glycoside mit einem Oligomerisationsgrad bis vorzugsweise etwa 8 geeignet sind. Der Oligomerisierungsgrad ist dabei ein statistischer Mittelwert, dem eine für solche technischen Produkte übliche Homologenverteilung zugrunde liegt.The addition products of ethylene oxide and / or of propylene oxide to fatty alcohols, fatty acids, alkylphenols or castor oil are known, commercially available products. These are mixtures of homologues whose mean degree of alkoxylation corresponds to the ratio of the amounts of ethylene oxide and / or propylene oxide and substrate, with which the addition reaction is carried out corresponds. C 12/18 fatty acid mono- and diesters of addition products of ethylene oxide with glycerol are known from DE 2024051 PS as refatting agents for cosmetic preparations. C 8/18 alkyl mono- and oligoglycosides, their preparation and their use are known in the art. They are prepared in particular by reacting glucose or oligosaccharides with primary alcohols having 8 to 18 carbon atoms. With regard to the glycoside radical, both monoglycosides in which a cyclic sugar residue is glycosidically linked to the fatty alcohol and oligomeric glycosides having a degree of oligomerization of preferably approximately 8 are suitable. The degree of oligomerization is a statistical mean, which is based on a homolog distribution typical for such technical products.

    Weiterhin können als Emulgatoren zwitterionische Tenside verwendet werden. Als zwitterionische Tenside werden solche oberflächenaktiven Verbindungen bezeichnet, die im Molekül mindestens eine quartäre Ammoniumgruppe und mindestens eine Carboxylat- und eine Sulfonatgruppe tragen. Besonders geeignete zwitterionische Tenside sind die sogenannten Betaine wie die N-Alkyl-N,N-dimethylammoniumglycinate, beispielsweise das Kokosalkyldimethylammoniumglycinat, N-Acylaminopropyl-N,N-dimethylammoniumglycinate, beispielsweise das Kokosacylaminopropyldimethylammoniumglycinat, und 2-Alkyl-3-carboxylmethyl-3-hydroxyethylimidazoline mit jeweils 8 bis 18 C-Atomen in der Alkyl- oder Acylgruppe sowie das Kokosacylaminoethylhydroxyethylcarboxymethylglycinat. Besonders bevorzugt ist das unter der CTFA-Bezeichnung Cocamidopropyl Betaine bekannte Fettsäureamid-Derivat. Ebenfalls geeignete Emulgatoren sind ampholytische Tenside. Unter ampholytischen Tensiden werden solche oberflächenaktiven Verbindungen verstanden, die außer einer C8/18-Alkyl- oder -Acylgruppe im Molekül mindestens eine freie Aminogruppe und mindestens eine -COOH- oder -SO3H-Gruppe enthalten und zur Ausbildung innerer Salze befähigt sind. Beispiele für geeignete ampholytische Tenside sind N-Alkylglycine, N-Alkylpropionsäuren, N-Alkylaminobuttersäuren, N-Alkyliminodipropionsäuren, N-Hydroxyethyl-N-alkylamidopropylglycine, N-Alkyltaurine, N-Alkylsarcosine, 2-Alkylaminopropionsäuren und Alkylaminoessigsäuren mit jeweils etwa 8 bis 18 C-Atomen in der Alkylgruppe. Besonders bevorzugte ampholytische Tenside sind das N-Kokosalkylaminopropionat, das Kokosacylaminoethylaminopropionat und das C12/18-Acylsarcosin.Furthermore, zwitterionic surfactants can be used as emulsifiers. Zwitterionic surfactants are those surface-active compounds which carry at least one quaternary ammonium group and at least one carboxylate and one sulfonate group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines such as the N-alkyl-N, N-dimethylammoniumglycinate, for example Kokosalkyldimethylammoniumglycinat, N-acylaminopropyl-N, N-dimethylammoniumglycinate, for example Kokosacylaminopropyldimethylammoniumglycinat, and 2-alkyl-3-carboxylmethyl-3-hydroxyethylimidazoline each having 8 to 18 carbon atoms in the alkyl or acyl group and the Kokosacylaminoethylhydroxyethylcarboxymethylglycinat. Particularly preferred is the fatty acid amide derivative known under the CTFA name Cocamidopropyl Betaine . Also suitable emulsifiers are ampholytic surfactants. Ampholytic surfactants are understood as meaning those surface-active compounds which, apart from a C 8/18 -alkyl or -acyl group in the molecule, contain at least one free amino group and at least one -COOH or -SO 3 H group and are capable of forming internal salts. Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids each having about 8 to 18 C Atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkylaminopropionate, cocoacylaminoethylaminopropionate and C 12/18 acylsarcosine.

    Schließlich kommen auch Kationtenside als Emulgatoren in Betracht, wobei solche vom Typ der Esterquats, vorzugsweise methylquatemierte Difettsäuretriethanolaminester-Salze, besonders bevorzugt sind.Finally, cationic surfactants are also suitable as emulsifiers, those of the type of Esterquats, preferably methyl-quaternized difatty acid triethanolamine ester salts, more preferably are.

Werden höhere Polyolmengen, vorzugsweise Glycerin oder Ethylenglycol eingesetzt, werden die Konzentrate gleichzeitig gegen mikrobiellen Befall stabilisiert.The amount used of the polyols is - based on the surfactant preparations - typically in Range of 0.1 to 15 and preferably 0.5 to 5 wt .-%. Be higher amounts of polyol, preferably Glycerol or ethylene glycol used, the concentrates are simultaneously against microbial Infestation stabilized.

    Herstellverfahrenmanufacturing

    Üblicherweise erfolgt die Herstellung der tensidischen Zubereitungen, indem man eine wäßrige Tensid- bzw. Emulgatorlösung, gegebenenfalls zusammen mit weiteren Hilfs- und Zusatzstoffen bei 10 bis 25 °C vorlegt, und die Mischung aus Perlglanzwachs und Polyolester bei dieser Temperatur einträgt, homogenisiert und auskristallisieren läßt. Femer ist es möglich, eine konzentrierte wäßrige (Anion)-Tensidpaste vorzulegen, die Mischung aus Perlglanzwachs und Polyolester in der Kälte einzurühren und die Mischung anschließend mit weiterem Wasser auf die gewünschte Konzentration zu verdünnen oder das Vermischen in Gegenwart polymerer hydrophiler Verdickungsmittel, wie etwa Hydroxypropylcellulosen, Xanthan Gum oder Polymeren vom Carbomer-Typ durchzuführen. Schließlich kann die Mischung aus Perlglanzwachs und Polyolester auch schon in einer Teilmenge der wäßrigen Tensidlösung gelöst bzw. dispergiert sein und so mit der Hauptmenge der Zubereitung vermischt werden. The preparation of the surface-active preparations is usually carried out by reacting an aqueous surfactant or emulsifier solution, optionally together with other auxiliaries and additives at 10 to 25 ° C, and the mixture of pearlescent wax and polyol ester enters at this temperature, homogenized and crystallize. Furthermore, it is possible to use a concentrated aqueous (anion) surfactant paste to apply the mixture of pearlescent wax and polyol ester in the cold stir and then diluting the mixture with further water to the desired concentration or mixing in the presence of polymeric hydrophilic thickeners, such as hydroxypropylcelluloses, Xanthan gum or carbomer-type polymers. Finally, the Blend of pearlescent wax and polyol ester even in a subset of the aqueous surfactant solution be dissolved or dispersed and so mixed with the bulk of the preparation.
