Description

"Gefor te Körperreinigungsmittel" "Required body cleansers"
Gegenstand der Erfindung sind geformte Körperreinigungsmittel auf Basis von Natriumsalzen von Ci2-Ci8-Acylisethionaten mit Zusätzen zur Verbesserung der Formbarkeit und der Schaumeigenschaften.The invention relates to shaped body cleansers based on sodium salts of Ci2-Ci8-acyl isethionates with additives for improving the formability and the foam properties.
Es ist bekannt, die Natriumsalze von Ci2-Ci8-Acylisethionaten ähn¬ lich wie Seifen auf Fettsäurebasis durch Kneten, PiTieren, Strang¬ pressen, Extrudieren, Schneiden und Stückpressen in eine geeignete Form für den Transport und für die Anwendung zu bringen. Auf diese Weise lassen sich Nadeln, Granulate, Nudeln, Riegel und handliche Toilettenseifen-Stücke erzeugen. Die geringe Plastizität der Acyl- isethionate bedingt erhebliche Probleme bei der Verarbeitung zu geformten Produkten. Darüber hinaus ist das Schaumverhalten der Acylisethionate unbefriedigend, sie haben eine geringe Schaum¬ konsistenz und ein zu schwaches Anschäumverhalten. Es hat daher nicht an Versuchen gefehlt, durch Zusätze die Verarbeitungs- und Anwendungseigenschaften der Acylisethionate zu verbessern und für die Herstellung geformter Körperreinigungsmittel geeigneter zu machen.It is known to convert the sodium salts of Ci2-Ci8-acyl isethionates into a suitable form for transport and use, similar to fatty acid-based soaps, by kneading, pitting, extruding, extruding, cutting and bar-pressing. In this way, needles, granules, pasta, bars and handy toilet soap pieces can be produced. The low plasticity of the acyl isethionates causes considerable problems when processing into shaped products. In addition, the foaming behavior of the acyl isethionates is unsatisfactory, they have a low foam consistency and the foaming behavior is too weak. There has therefore been no lack of attempts to improve the processing and application properties of the acyl isethionates by additives and to make them more suitable for the production of shaped personal cleansers.

Acylisethionate sind seit langem bekannte, hautfreundliche ober¬ flächenaktive Stoffe, die durch Veresterung von Fettsäuren mit dem Natriumsalz der 2-Hydroxyethan-sulfonsäure (Isethionsäure), z. B. nach dem Verfahren, das in US 3,320,292 beschrieben ist, zugäng¬ lich sind. Wenn mann für diese Veresterung Fettsäuren mit 12 bis 18 C-Atomen, also z. B. Laurin-, Myristin-, Palimitin- oder Stearinsäure oder auch technische Fettsäurefraktionen, z. B. die aus Kokosfettsäure erhältliche Ci2-C18~rTet'tsäurefraktion einsetzt, erhält man die erfindungsgemäß geeigneten Ci2-Ci8-Acylisethionate. Die Sulfobernsteinsäure onoalkyl(Cs-CisJ-ester-dinatriumsalze wer¬ den nach bekanntem Verfahren z. B. dadurch hergestellt, daß man Maleinsäureanhydrid mit einem Fettalkohol mit 8 - 18 C-Atomen zum Maleinsäuremonoester des Fettalkohols umsetzt und diesen mit Natriumsulfit zum Sulfobernsteinsäureester sulfitiert. Besonders geeignete Sulfobernsteinsäureester leiten sich von Fettalkohol¬ fraktionen mit 12 - 18 C-Atomen ab, wie sie z. B. aus Kokosfett¬ säure oder Kokosfettsäuremethylester durch Hydrierung zugänglich sind.Acyl isethionates have long been known, skin-friendly surface-active substances which, by esterification of fatty acids with the sodium salt of 2-hydroxyethanesulfonic acid (isethionic acid), e.g. B. are accessible by the method described in US 3,320,292. If man for this esterification fatty acids with 12 to 18 carbon atoms, so z. B. lauric, myristic, palimitic or stearic acid or technical fatty acid fractions, e.g. B. uses the Ci2-C18 ~ rTet 'acid fraction available from coconut fatty acid, the Ci2- Ci8 acyl isethionates suitable according to the invention are obtained. The sulfosuccinic acid onoalkyl (Cs-CisJ-ester disodium salts are prepared according to the known method, for example by reacting maleic anhydride with a fatty alcohol having 8-18 C atoms to form the maleic acid monoester of the fatty alcohol and sulfitating it with sodium sulfite to the sulfosuccinic acid ester. Particularly suitable sulfosuccinic acid esters are derived from fatty alcohol fractions with 12-18 C atoms, such as those obtained from coconut fatty acid or coconut fatty acid methyl ester by hydrogenation.
Als gesättigte lineare Fettsäuren eignen sich vor allem die aus pflanzlichen und tierischen Fetten nach Hydrierung der Doppel¬ bindungen erhältlichen Fettsäuren. Bevorzugt sind Palmitin- und Stearinsäure und technische Gemische dieser Fettsäuren.Particularly suitable as saturated linear fatty acids are the fatty acids obtainable from vegetable and animal fats after hydrogenation of the double bonds. Palmitic and stearic acid and industrial mixtures of these fatty acids are preferred.
Als feinteilige, wasserunlösliche Alkalialuminiumsilikate eignen sich synthetische, gebundenes Wasser enthaltende, kristaline Natriumalumosilikate, vorzugsweise Zeolith NaA. Brauchbar ist auch der Zeolith NaX sowie dessen Gemische mit Zeolith NaA. Geeignete Zeolithe besitzen ein Calciumbindevermögen, das nach den Angaben in DE 24 12 837 bestimmt wird und das im Bereich von 100 bis 200 mg CaO/g liegt. Bevorzugt kommt der mit dem Handelsnamen Wessalith P (Degussa) erhältliche Zeolith NaA mit einem Gehalt von ca. 20 Gew.-% gebundende Wasser in einer Menge von 8 - 15 Gew.-% zur Anwendung.Suitable finely divided, water-insoluble alkali aluminum silicates are synthetic, bound water-containing, crystalline sodium aluminosilicates, preferably zeolite NaA. The zeolite NaX and its mixtures with zeolite NaA can also be used. Suitable zeolites have a calcium binding capacity which is determined according to the information in DE 24 12 837 and which is in the range from 100 to 200 mg CaO / g. The zeolite NaA obtainable with the trade name Wessalith P (Degussa) with a content of approx. 20% by weight bound water is preferably used in an amount of 8-15% by weight.
Als weitere Plastifikatoren und Bindemittel können die erfindungs¬ gemäßen geformten Körperreinigungsmittel die für solche Zwecke bekannten Stoffe enthalten. Dies sind z. B. neutrale Fettstoffe, bevorzugt solche aus der Gruppe der Fettalkohole mit 12 - 22 C-Atomen, der Fettsäureglyceride von Ci2~C22-f:ettsäu en oder der Fettsäure (Ci2-C22)-r^tta^ohol(Ci2-C22)"es'ter' "*^e bevorzugt in Mengen von 1 - 15 Gew.-%, bezogen auf die geformten Körperreini¬ gungsmittel, eingesetzt werden.As further plasticizers and binders, the shaped personal cleansing agents according to the invention can contain the substances known for such purposes. These are e.g. B. neutral fatty substances, preferably those from the group of fatty alcohols with 12-22 carbon atoms, the fatty acid glycerides of Ci2 ~ C22-f : ettsäu en or the fatty acid (Ci2-C22) - r ^ tta ^ ohol (Ci2-C22) "es'ter'" * ^ e preferred in Quantities of 1-15% by weight, based on the shaped body cleansing agents, are used.
Als Zusätze zur weiteren Verbesserung der Cremigkeit des Schaumes und des Hautgefühls während und nach der Anwendung haben sich auch noch weitere Stoffe bewährt, deren zusätzliche Verwendung zur Her¬ stellung der erfindungsgemäßen, geformten Körperreinigungsmittel empfohlen werden kann: Besonders bevorzugt sind daher erfindungs¬ gemäße geformte Körperreinigungsmittel mit einem zusätzlichen Gehalt von 1 - 10 Gew.-% an nichtionischen Tensiden vom Typ der Polyglycolether mit einem HLB-Wert von 12 - 18. Solche Produkte werden durch Anlagerung von Ethylenoxid an z. B. Fettalkohole mit 12 - 18 C-Atomen, an Fettsäuren mit 12 - 18 C-Atomen oder an Glycerin- oder Sorbitanfettsäure-Partialester auf Basis von Ci2-Ci8-Fettsäuren oder an Fettsäurealkanolamide hergestellt. Der HLB-Wert bedeutet den Anteil an hydrophilen Gruppen, z. B. an Glycolether- oder Polyol-Gruppen bezogen auf das Gesamt-Molekül und er errechnet sich nach der BeziehungAs additives for further improving the creaminess of the foam and the feeling of the skin during and after use, other substances have also proven themselves, the additional use of which can be recommended for the production of the shaped body cleansing agents according to the invention: Shaped body cleaning agents according to the invention are therefore particularly preferred with an additional content of 1-10% by weight of nonionic surfactants of the polyglycol ether type with an HLB value of 12-18. Such products are made by adding ethylene oxide to e.g. B. fatty alcohols with 12-18 C atoms, on fatty acids with 12-18 C atoms or on glycerol or sorbitan fatty acid partial esters based on Ci2-Ci8 fatty acids or on fatty acid alkanolamides. The HLB value means the proportion of hydrophilic groups, e.g. B. on glycol ether or polyol groups based on the total molecule and it is calculated according to the relationship
HLB = 1/5 x (100-Gew.% L),HLB = 1/5 x (100 wt.% L),
wobei Gew.-% L der Gewichtsanteil an liphophilen Gruppen, also z. B. an Alkyl- oder Acylgruppen mit 12-18 C-Atomen im Tensid- molekül darstellt.where wt .-% L is the proportion by weight of lipophilic groups, ie z. B. represents alkyl or acyl groups with 12-18 C atoms in the tenside molecule.
Weiterhin sind solche erfindungsgemäßen, geformten Körperreini¬ gungsmittel bevorzugt, die zur Verbesserung des Schaumverhaltens und der Hautverträglichkeit einen Zusatz von 1 - 10 Gew.-% eines wasserlöslichen Salzes eines wasserlöslichen Eiweißhydrolysat- Fettsäure-Kondensationsproduktes enthalten. Diese werden durch Kondensation von Fettsäuren, bevorzugt von Fettsäuren mit 12 - 18 C-Atomen mit Aminosäuren, Mono-, Di- und wasserlöslichen Oligopep- tiden und Gemischen solcher Produkte hergestellt, wie sie bei der Hydrolyse von Proteinen anfallen. Diese Eiweißhydrolysat-Fett- säure-Kondensationsprodukte werden mit einer Base neutralisiert und liegen dann bevorzugt als Alkali-, Ammonium-, Mono-, Di- oder Trialkanolammoniumalz vor. Solche Produkte sind unter dem Waren¬ zeichen LAMEPON (R) oder MAYPON (R) seit langem im Handel erhält¬ lich und werden als hautfreundliche Tenside eingesetzt.Furthermore, those shaped body cleansers according to the invention are preferred which contain an addition of 1-10% by weight of a water-soluble salt of a water-soluble protein hydrolyzate-fatty acid condensation product to improve the foaming behavior and skin tolerance. These are obtained by condensing fatty acids, preferably fatty acids with 12-18 Carbon atoms made with amino acids, mono-, di- and water-soluble oligopeptides and mixtures of such products as are obtained in the hydrolysis of proteins. These protein hydrolyzate-fatty acid condensation products are neutralized with a base and are then preferably present as alkali, ammonium, mono-, di- or trialkanolammonium salt. Such products have long been commercially available under the trademark LAMEPON ( R ) or MAYPON ( R ) and are used as skin-friendly surfactants.
Als besonders vorteilhaft hat sich auch ein Zusatz eines an sich bekannten Emulgators vom Typ Wasser-in-Öl in einer Menge von ca. 1 - 5 Gew.-% erwiesen. Dabei handelt es sich um einen Mischester, der ein Kondensationsprodukt aus einem Pentaerythrit-di-fettsäure- ester und einem Zitronensäure-di-fettalkoholester darstellt, wie es in DE-PS 11 65574 näher beschrieben ist. Durch den Zusatz sol¬ cher Mischester wird ein besonders cremiger, feinblasiger Schaum und ein angenehmes Hautgefühl bei der Anwendung des Körperreini¬ gungsmittels erreicht.An addition of a water-in-oil type emulsifier known per se in an amount of about 1-5% by weight has also proven to be particularly advantageous. This is a mixed ester, which is a condensation product of a pentaerythritol di-fatty acid ester and a citric acid di-fatty alcohol ester, as described in more detail in DE-PS 11 65574. The addition of such mixed esters results in a particularly creamy, fine-bubble foam and a pleasant feeling on the skin when using the body cleanser.

Für die Herstellung von handlichen Syndet-Seifenstücken hat sich die folgende Verfahrensweise besonders bewährt:Degree of oxyethylation 10-20) 3-10% by weight protein hydrolyzate-fatty acid condensation product 1-5% by weight water The cleaning agents shaped according to the invention can be produced in the manner customary for such products, the combination of additives according to the invention resulting in a particularly readily formable mass which is plastic under heat and hard after cooling, and the shaped products have a smooth surface . Usual methods for mixing or homogenizing, kneading, optionally piling, extrusion, optionally pelleting, extruding, cutting and unit pressing, as described in the publication in JAOCS, vol. 59, no. 10 (October 1982) can be used for the production of the cleaning agents shaped according to the invention. The following procedure has proven particularly useful for the production of handy Syndet soap bars:
Die schmelzbaren Komponenten, z. B. der Fettalkohol, die Fett¬ säuren, die nichtionogenen Tenside und gegebenenfalls enthaltene, schmelzbare organische Füll- und Hilfsstoffe werden bei Temperatu¬ ren von 60 bis 90 °C in einem heizbaren Kneter oder Mischer aufge¬ schmolzen und gemischt. Dann erfolgt die Zugabe des Ci2-Ci8~Acyl- isethionat-Natriumsalzes, des Sulfobernsteinsäuremonoalkyl- (Ci2-Ci8)-ester-Dinatriumsalzes, des Zeolith NaA und des Fett- säure-Oligopeptid-Kondensationsproduktes sowie gegebenenfalls weiterer bei 60 bis 90 °C nicht schmelzbarer Komponenten und des Wassers, sowie eine Vermischung oder Verknetung des Ansatzes bei einer Temperatur von ca. 70 °C. Eine weitere Homogenisierung läßt sich dadurch erreichen, daß die Masse mehrfach durch Siebe gepreßt und schließlich bei einer Kopftemperatur von 40 bis 70 °C zu einem Strang verpreßt wird, der zu gleich äßgen Stücken geschnitten wird. Die Stücke können schließlich in einer Formpresse in eine endgültige Form gebracht werden. Anstelle der Strangpresse kann auch eine Extrusion durch eine Lochplatte erfolgen, wobei die erfindungsgemäßen Reinigungsmittel nach dem Erkalten in Form von Nadeln oder, wenn der Lochplatte Messer nachgeschaltet sind, in Form von Granulaten erhalten werden.The fusible components, e.g. B. the fatty alcohol, the fatty acids, the non-ionic surfactants and any fusible organic fillers and auxiliaries contained are melted and mixed at temperatures from 60 to 90 ° C. in a heatable kneader or mixer. Then the addition of the Ci2-Ci8 ~ acyl isethionate sodium salt, the sulfosuccinic acid monoalkyl- (Ci2-Ci8) ester disodium salt, the zeolite NaA and the fatty acid-oligopeptide condensation product and optionally not at 60 to 90 ° C are not added meltable components and the water, as well as mixing or kneading the mixture at a temperature of approx. 70 ° C. A further homogenization can be achieved in that the mass is pressed several times through sieves and finally pressed at a head temperature of 40 to 70 ° C into a strand which is cut into equal pieces. The pieces can finally be brought into a final shape in a molding press. Instead of the extrusion press, extrusion through a perforated plate can also take place, the cleaning agents according to the invention can be obtained after cooling in the form of needles or, if the perforated plate is followed by knives, in the form of granules.
