Definitions
- Shaped soap product containing talc, one or more fatty acids in the form of their Alkaline soaps and one or more non-ionic surfactants in the absence of Alkyl (oligo) glycosides.
- the present invention relates to cosmetic cleaning agents in the form of shaped soap products. Such means are known per se. It is essentially about surface-active substances or mixtures of substances that the consumer in different Preparations are offered.
- the invention particularly relates to bar soaps with improved Smoothness and increased lime soap dispersing capacity due to the content of talc and one or more nonionic surfactants in the absence of alkyl (oligo) glycosides.
- Surfactants best known are the alkali salts of higher fatty acids, i.e. the classic "soaps" - are amphiphilic substances, the organic non-polar substances in water can emulsify.
- a simple water bath without the addition of surfactants is the first step swelling of the horny layer of the skin, the degree of this swelling being, for example, from depends on the duration of the bath and its temperature. At the same time, they become water-soluble Fabrics, e.g. water-soluble dirt components, but also the skin's own substances that Water binding capacity of the horny layer are responsible, washed off or washed out.
- water-soluble Fabrics e.g. water-soluble dirt components
- the syndet soap, so-called “Syndetbars” which are free of fatty acid salts except for impurities and contain only synthetic surfactants.
- the main components are the alkali salts of the fatty acids of natural oils and the like. Fat, preferably of chain lengths C 12 -C 18 . Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for fine soap production.
- the sodium salts of the fatty acid mixtures are solid, the potassium salts are soft-pasty. For saponification, the dilute sodium or potassium hydroxide solution is added to the fat raw materials in a stoichiometric ratio in such a way that the finished soap contains a maximum of 0.05% alkali. In many cases, soaps are no longer made directly from fats, but rather from the fatty acids obtained by fat splitting.
- Common soap additives are fatty acids, fatty alcohols, lanolin, lecithin, vegetable oils, partial glycerides and other fat-like substances for regreasing the cleansed skin, antioxidants such as ascorbyl palmitate or tocopherol to prevent the autoxidation of the Soap (rancidity), complexing agents such as nitrilotriacetate to bind traces of heavy metals, which could catalyze autoxidative spoilage, perfume oils to achieve the desired fragrance notes, dyes for coloring the soap bars and if desired special additives.
- Surfactants are amphiphilic substances that can dissolve organic, non-polar substances in water. Due to their specific molecular structure, they provide at least one hydrophilic and a hydrophobic part of the molecule, for a reduction of the surface tension of water, wetting the skin, facilitating dirt removal and solution, easy rinsing and - if desired - for foam regulation.
- Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in an acidic or neutral environment. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In aqueous solution they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and accordingly behave like anionic or cationic surfactants in aqueous solution depending on the pH. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment.
- Non-ionic surfactants form in aqueous medium no ions.
- GB 2 317 396 discloses a shaped soap product containing alkali fatty acid, another surfactant, e.g. a nonionic surfactant, free fatty acid and talc if possible.
- another surfactant e.g. a nonionic surfactant, free fatty acid and talc if possible.
- the object of the invention was therefore to provide bar soaps, that are free from the disadvantages described.
- new bar soap compositions must also be able to be produced on an industrial scale, d. H. that the compositions are, for example, sufficient but not too have high ductility and do not tend to crack when dried.

- Another advantage of this invention is its compatibility of the wash is improved because the total content of surfactants is reduced becomes.
- the shaped soap products according to the invention also have mechanical properties Deformation a particularly smooth surface. When used they generate a creamy, stable foam.
- the lime soap deposit formed in hard water remains dispersed in the water and does not lead to the gray-greasy deposits on the upper area of sanitary objects.
- Talc is a hydrated magnesium silicate with the composition 3MgO ⁇ 4SO 2 ⁇ H 2 O or Mg 3 (Si 4 O 10 ) ⁇ (OH) 2 or Mg 6 (OH) 4 [Si 8 O 20 ] or Mg 12 [Si 16 O 40 ], which, however, can contain proportions of hydrated magnesium aluminum silicate of up to 12% by weight Al 2 O 3 , based on the entire product.
- Talc is a white, mostly very fine, practically odorless to earthy-smelling powder that feels greasy when rubbed without being fat. It is insoluble in water, cold acids or alkalis.

Abstract
Description
Geformtes Seifenprodukt, enthaltend Talkum, eine oder mehrere Fettsäuren in Form ihrer Alkaliseifen und ein oder mehrere nichtionische Tenside bei gleichzeitiger Abwesenheit von Alkyl-(oligo)-glycosiden.Shaped soap product containing talc, one or more fatty acids in the form of their Alkaline soaps and one or more non-ionic surfactants in the absence of Alkyl (oligo) glycosides.
Die vorliegende Erfindung betrifft kosmetische Reinigungsmittel in Form geformter Seifenprodukte. Derartige Mittel sind an sich bekannt. Es handelt sich dabei im wesentlichen um oberflächenaktive Substanzen oder Stoffgemische, die dem Verbraucher in verschiedenen Zubereitungen angeboten werden. Die Erfindung betrifft insbesondere Stückseifen mit verbesserter Glätte und erhöhtem Kalkseifendispergiervermögen durch einen Gehalt an Talkum und einem oder mehreren nichtionischen Tensiden bei gleichzeitiger Abwesenheit von Alkyl-(oligo)-glycosiden.The present invention relates to cosmetic cleaning agents in the form of shaped soap products. Such means are known per se. It is essentially about surface-active substances or mixtures of substances that the consumer in different Preparations are offered. The invention particularly relates to bar soaps with improved Smoothness and increased lime soap dispersing capacity due to the content of talc and one or more nonionic surfactants in the absence of alkyl (oligo) glycosides.
Oberflächenaktive Stoffe - am bekanntesten die Alkalisalze der höheren Fettsäuren, also die klassischen "Seifen" - sind amphiphile Stoffe, die organische unpolare Substanzen in Wasser emulgieren können.Surfactants - best known are the alkali salts of higher fatty acids, i.e. the classic "soaps" - are amphiphilic substances, the organic non-polar substances in water can emulsify.
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. Es ist zwar eine große Zahl recht milder Tenside erhältlich, jedoch sind die Tenside des Standes der Technik entweder mild, reinigen aber schlecht, oder aber sie reinigen gut, reizen jedoch Haut oder Schleimhäute.These substances not only wash dirt from the skin and hair, they irritate, depending on the choice of the surfactant or the surfactant mixture, skin and mucous membranes more or less strong. It Although a large number of fairly mild surfactants are available, the surfactants are of the state technology either mild, but cleans badly, or they clean well but irritate Skin or mucous membranes.
Schon bei einem einfachen Wasserbade ohne Zusatz von Tensiden kommt es zunächst zu einer Quellung der Hornschicht der Haut, wobei der Grad dieser Quellung beispielsweise von der Dauer des Bades und dessen Temperatur abhängt. Zugleich werden wasserlösliche Stoffe, z.B. wasserlösliche Schmutzbestandteile, aber auch hauteigene Stoffe, die für das Wasserbindungsvermögen der Hornschicht verantwortlich sind, ab- bzw. ausgewaschen. A simple water bath without the addition of surfactants is the first step swelling of the horny layer of the skin, the degree of this swelling being, for example, from depends on the duration of the bath and its temperature. At the same time, they become water-soluble Fabrics, e.g. water-soluble dirt components, but also the skin's own substances that Water binding capacity of the horny layer are responsible, washed off or washed out.
Durch hauteigene oberflächenaktive Stoffe werden zudem auch Hautfette in gewissem Ausmaße gelöst und ausgewaschen. Dies bedingt nach anfänglicher Quellung eine nachfolgende deutliche Austrocknung der Haut, die durch waschaktive Zusätze nach verstärkt werden kann.Due to the skin's own surface-active substances, skin fats are also to a certain extent loosened and washed out. After initial swelling, this requires a subsequent one significant dehydration of the skin, which is intensified by washing-active additives can.
Diesen Übelständen galt es also, Abhilfe zu schaffen.The aim was to remedy these problems.
Bei gesunder Haut sind diese Vorgänge im allgemeinen belanglos, da die Schutzmechanismen der Haut solche leichten Störungen der oberen Hautschichten ohne weiteres kompensieren können. Aber bereits im Falle nichtpathologischer Abweichungen vom Normalstatus, z.B. durch umweltbedingte Abnutzungsschäden bzw. Irritationen, Lichtschäden, Altershaut usw., ist der Schutzmechanismus der Hautoberfläche gestört. Unter Umständen ist er dann aus eigener Kraft nicht mehr imstande, seine Aufgabe zu erfüllen und muß durch exteme Maßnahmen regeneriert werden. Aufgabe der vorliegenden Erfindung war somit, diesem Mangel des Standes der Technik Abhilfe zu schaffen.With healthy skin, these processes are generally irrelevant because of the protective mechanisms the skin easily compensate for such slight disorders of the upper layers of the skin can. But already in the case of non-pathological deviations from normal status, e.g. through environmental wear and tear or irritation, light damage, aging skin etc., the protective mechanism of the skin surface is disturbed. Under certain circumstances then he is no longer able to fulfill his task under his own power and has to go through extreme measures are regenerated. The object of the present invention was therefore to remedy this lack of the prior art.
Bei der Körperreinigung spielen Stückseifen eine große Rolle, die heutzutage großtechnisch durch kontinuierliche Verseifung von freien Fettsäuren mit Alkalien, Aufkonzentrieren der Grundseifen und Sprühtrocknung hergestellt werden. Man unterscheidet dabei zwischen echten Alkaliseifen, die ausschließlich Fettsäuresalze und gegebenenfalls noch freie Fettsäuren enthalten und sogenannten "Combibars", Stückseifen, die neben Fettsäuresalzen noch weitere synthetische Tenside, in der Regel Fettalkoholethersulfate oder Fettsäureisothionate aufweisen. Eine Sonderstellung nehmen hingegen die Syndetstückseifen, sogenannte "Syndetbars" ein, die bis auf Verunreinigungen frei von Fettsäuresalzen sind und ausschließlich synthetische Tenside enthalten.Bar soaps play a major role in body cleansing, which on an industrial scale these days by continuously saponifying free fatty acids with alkalis, concentrating the Basic soaps and spray drying can be produced. One differentiates between real alkali soaps that contain only fatty acid salts and possibly free fatty acids contain and so-called "combibars", bar soaps, which in addition to fatty acid salts even more synthetic surfactants, usually fatty alcohol ether sulfates or fatty acid isothionates exhibit. The syndet soap, so-called "Syndetbars" which are free of fatty acid salts except for impurities and contain only synthetic surfactants.
Allein in Deutschland werden jährlich mehrere Millionen Stück Seifen für die Körperhygiene verkauft. Die Anforderungen des Marktes an diesen Massenverbrauchsartikel werden dabei jedoch immer höher: Stückseifen müssen die Haut nicht nur reinigen, sondem auch pflegen, d. h. ein Austrocknen verhindern, rückfetten und einen Schutz gegen Einflüsse von außen bieten. Selbstverständlich wird erwartet, daß die Seife in besonderem Masse hautverträglich ist, sie soll aber in der Anwendung dennoch möglichst viel und cremigen Schaum ergeben und ein angenehmes Hautgefühl bewirken. In diesem Zusammenhang suchen Hersteller von Stückseifen ständig nach neuen Inhaltsstoffen, die diesem gestiegenen Anforderungsprofil Rechnung tragen.In Germany alone, several million soap bars are used every year for personal hygiene sold. The requirements of the market for this mass consumer item are thereby however, ever higher: bar soaps not only have to clean the skin, they also have to care for it, d. H. prevent drying out, regreasing and protection against external influences Offer. Of course, the soap is expected to be particularly skin-friendly is, but it should still result in as much and creamy foam in use and cause a pleasant feeling on the skin. In this context, manufacturers of Bar soaps constantly looking for new ingredients that meet this increased requirement profile Take into account.
Man unterscheidet feste, meist stückförmige, und flüssige Seifen. Hauptbestandteile sind die Alkalisalze der Fettsäuren natürlicher Öle u. Fette, vorzugsweise der Kettenlängen C12-C18. Da Laurinsäureseifen besonders gut schäumen, sind die laurinsäurereichen Kokos- und Palmkernöle bevorzugte Rohstoffe für die Feinseifenherstellung. Die Natriumsalze der Fettsäüregemische sind fest, die Kaliumsalze weich-pastös. Zur Verseifung wird die verdünnte Natron- oder Kalilauge den Fettrohstoffen im stöchiometrischen Verhältnis so zugesetzt, daß in der fertigen Seife ein Laugenüberschuß von höchstens 0,05% vorhanden ist. Vielfach werden die Seifen heute nicht mehr direkt aus den Fetten, sondem aus den durch Fettspaltung gewonnenen Fettsäuren hergestellt.A distinction is made between solid, mostly bar-shaped, and liquid soaps. The main components are the alkali salts of the fatty acids of natural oils and the like. Fat, preferably of chain lengths C 12 -C 18 . Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for fine soap production. The sodium salts of the fatty acid mixtures are solid, the potassium salts are soft-pasty. For saponification, the dilute sodium or potassium hydroxide solution is added to the fat raw materials in a stoichiometric ratio in such a way that the finished soap contains a maximum of 0.05% alkali. In many cases, soaps are no longer made directly from fats, but rather from the fatty acids obtained by fat splitting.
Übliche Seifen-Zusätze sind Fettsäuren, Fettalkohole, Lanolin, Lecithin, pflanzliche Öle, Partialglyceride und andere fettähnliche Substanzen zur Rückfettung der gereinigten Haut, Antioxidantien wie Ascorbylpalmitat oder Tocopherol zur Verhinderung der Autoxidation der Seife (Ranzigkeit), Komplexierungsmittel wie Nitrilotriacetat zur Bindung von SchwermetallSpuren, die den autoxidativen Verderb katalysieren könnten, Parfümöle zur Erzielung der gewünschten Duftnoten, Farbstoffe zur Einfärbung der Seifenstücke und gewünschtenfalls spezielle Zusätze.Common soap additives are fatty acids, fatty alcohols, lanolin, lecithin, vegetable oils, partial glycerides and other fat-like substances for regreasing the cleansed skin, antioxidants such as ascorbyl palmitate or tocopherol to prevent the autoxidation of the Soap (rancidity), complexing agents such as nitrilotriacetate to bind traces of heavy metals, which could catalyze autoxidative spoilage, perfume oils to achieve the desired fragrance notes, dyes for coloring the soap bars and if desired special additives.
Wichtigste Typen der Feinseifen sind:
- Toilettenseifen mit 20 - 50 % Kokosöl im Fettansatz, bis 5 % Rückfetter-Anteil und 0,5 - 2 % Parfümöl, sie bilden den größten Anteil der Feinseifen;
- Luxusseifen mit bis zu 5% besonders kostbarer Parfümöle;
- Deoseifen mit Zusätzen desodorierender Wirkstoffe, wie z. B. 3,4,4'-Trichlorcarbanilid (Triclocarban);
- Cremeseifen mit besonders hohen Anteilen rückfettender und die Haut cremender Substanzen;
- Babyseifen mit guter Rückfettung und zusätzlich pflegenden Anteilen wie z. B. Kamille-Extrakten, allenfalls sehr schwach parfümiert;
- Hautschutzseifen mit hohen Anteilen rückfettender Substanzen sowie weiteren pflegenden und schützenden Zusätzen, wie z. B. Proteinen;
- Transparentseifen mit Zusätzen von Glycerin, Zucker u. a., welche die Kristallisation der Fettsäuresalze in der erstarrten Seifenschmelze verhindern und so ein transparentes Aussehen bewirken;
- Schwimmseifen mit einer Dichte < 1, hervorgerufen durch bei der Herstellung kontrolliert eingearbeitete Luftbläschen.
- Seifen mit abrasiven Zusätzen zur Reinigung stark verschmutzter Hände.
- Toilet soaps with 20 - 50% coconut oil in the fat mixture, up to 5% moisturizing agent and 0.5 - 2% perfume oil, they form the largest part of fine soaps;
- Luxury soaps with up to 5% particularly valuable perfume oils;
- Deodorant soaps with additives of deodorising agents, such as. B. 3,4,4'-trichlorocarbanilide (triclocarban);
- Cream soaps with particularly high proportions of lipid-replenishing and skin-creaming substances;
- Baby soaps with good regreasing and additional nourishing components such as B. chamomile extracts, at most very slightly perfumed;
- Skin protection soaps with high proportions of moisturizing substances as well as other nourishing and protective additives, such as. B. proteins;
- Transparent soaps with additions of glycerin, sugar and others, which prevent the crystallization of the fatty acid salts in the solidified soap melt and thus create a transparent appearance;
- Floating soaps with a density <1, caused by air bubbles that are incorporated in a controlled manner during production.
- Soaps with abrasive additives for cleaning heavily soiled hands.
Beim Waschen mit Seife stellt sich in der Waschlauge ein pH-Wert von 8-10 ein. Diese Alkatität neutralisiert den natürlichen Säuremantel der Haut (pH-Wert 5-6). Dieser wird bei normaler Haut zwar relativ schnell rückgebildet, bei empfindlicher oder vorgeschädigter Haut kann es jedoch zu Irritationen kommen. Ein weiterer Nachteil der Seifen ist die Bildung unlöslicher Kalkseifen in hartem Wasser. Diese Nachteile liegen nicht vor bei Syndet-Seifen. Ihre Basis sind synthetische Aniontenside, die mit Gerüstsubstanzen, Rückfettem und weiteren Zusätzen zu seifenähnlichen Stücken verarbeitet werden können. Ihr pH-Wert ist in weiten Grenzen variierbar und wird meist neutral auf pH 7 oder dem Säuremantel der Haut angepaßt auf pH 5,5 eingestellt. Sie haben hervorragende Reinigungskraft, schäumen in jeder Wasserhärte, sogar in Meerwasser, der Anteil rückfettender Zusätze muß wegen ihrer intensiven Reinigungs- und Entfettungswirkung deutlich höher als bei normalen Seifen sein. Ihr Nachteil ist der relativ hohe Preis.When washing with soap, the pH of the wash liquor is 8-10. This alkalinity neutralizes the skin's natural acid coat (pH 5-6). This is at Normal skin regressed relatively quickly, with sensitive or damaged skin however, there may be irritation. Another disadvantage of soaps is the formation of insoluble ones Lime soaps in hard water. These disadvantages do not exist with Syndet soaps. They are based on synthetic anionic surfactants, with builders, refatting agents and others Additives to soap-like pieces can be processed. Their pH is wide Limits can be varied and are usually adjusted neutrally to pH 7 or the acid coat of the skin adjusted to pH 5.5. They have excellent cleaning power, foam in everyone Water hardness, even in sea water, the proportion of lipid-replenishing additives has to be intense The cleaning and degreasing effect can be significantly higher than that of normal soaps. you The disadvantage is the relatively high price.
Tenside sind amphiphile Stoffe, die organische, unpolare Substanzen in Wasser lösen können. Sie sorgen, bedingt durch ihren spezifischen Molekülaufbau mit mindestens einem hydrophilen und einem hydrophoben Molekülteil, für eine Herabsetzung der Oberflächenspannung des Wassers, die Benetzung der Haut, die Erleichterung der Schmutzentfernung und -lösung, ein leichtes Abspülen und - je nach Wunsch - für Schaumregulierung.Surfactants are amphiphilic substances that can dissolve organic, non-polar substances in water. Due to their specific molecular structure, they provide at least one hydrophilic and a hydrophobic part of the molecule, for a reduction of the surface tension of water, wetting the skin, facilitating dirt removal and solution, easy rinsing and - if desired - for foam regulation.
Bei den hydrophilen Anteilen eines Tensidmoleküls handelt es sich meist um polare funktionelle Gruppen, beispielweise -COO-, -OSO3 2-, -SO3 -, während die hydrophoben Teile in der Regel unpolare Kohlenwasserstoffreste darstellen. Tenside werden im allgemeinen nach Art und Ladung des hydrophilen Molekülteils klassifiziert. Hierbei können vier Gruppen unterschieden werden:
- anionische Tenside,
- kationische Tenside,
- amphotere Tenside und
- nichtionische Tenside.
- anionic surfactants,
- cationic surfactants,
- amphoteric surfactants and
- nonionic surfactants.
Anionische Tenside weisen als funktionelle Gruppen in der Regel Carboxylat-, Sulfat- oder
Sulfonatgruppen auf. In wäßriger Lösung bilden sie im sauren oder neutralen Milieu negativ
geladene organische lonen. Kationische Tenside sind beinahe ausschließlich durch das Vorhandensein
einer quaternären Ammoniumgruppe gekennzeichnet. In wäßriger Lösung bilden
sie im sauren oder neutralen Milieu positiv geladene organische Ionen. Amphotere Tenside
enthalten sowohl anionische als auch kationische Gruppen und verhalten sich demnach in
wäßriger Lösung je nach pH-Wert wie anionische oder kationische Tenside. Im stark sauren
Milieu besitzen sie eine positive und im alkalischen Milieu eine negative Ladung. Im neutralen
pH-Bereich hingegen sind sie zwitterionisch, wie das folgende Beispiel verdeutlichen soll:
Typisch für nicht-ionische Tenside sind Polyether-Ketten. Nicht-ionische Tenside bilden in wäßrigem Medium keine Ionen.Polyether chains are typical of non-ionic surfactants. Non-ionic surfactants form in aqueous medium no ions.
Es ist bekannt, daß Feinseifen auf Basis von Talg- und Kokosfettsäuren durch zahlreiche Zusatzstoffe in ihren anwendungstechnischen Eigenschaften verändert und verbessert werden können. In gängigen Handbüchem, z. B. Geoffrey Martin: The Modem Soap and Detergent Industry, Vol. 1, (1959), Kapitel VI, sind zwar anorganische Füllstoffe als Streckmittel für Seifen beschrieben, dabei wird dem Talkum jedoch eher eine nachteilige Wirkung in Stückseifen zugeschrieben. Der Zusatz von 5-20% Talkum in Combibars wird in DE 196 49 896 beschrieben. Durch diesen Zusatz soll die Glätte und das Kalkseifendispergiervermögen verbessert werden.It is known that fine soaps based on tallow and coconut fatty acids by numerous Additives in their application properties are changed and improved can. In common manuals, e.g. B. Geoffrey Martin: The Modem Soap and Detergent Industry, Vol. 1, (1959), Chapter VI, are inorganic fillers as extenders for Soaps are described, but the talc is more of an adverse effect in bar soaps attributed. The addition of 5-20% talc in combibars is described in DE 196 49 896 described. This addition is intended to smoothen and disperse the lime soap be improved.
GB 2 317 396 offenbart ein geformtes Seifenprodukt enthaltend Alkalifettsäure, ein weiteres Tensid, z.b. ein nichtionisches Tensid, freie Fettsäure und möglichst Talkum.GB 2 317 396 discloses a shaped soap product containing alkali fatty acid, another surfactant, e.g. a nonionic surfactant, free fatty acid and talc if possible.
Die Aufgabe der Erfindung hat somit darin bestanden, Stückseifen zur Verfügung zu stellen, die frei von den geschilderten Nachteilen sind. Dabei war insbesondere auch zu berücksichtigen, daß neue Stückseifenzusammensetzungen auch großtechnisch herstellbar sein müssen, d. h. daß die Zusammensetzungen beispielsweise eine ausreichende, aber nicht zu hohe Verformbarkeit besitzen und beim Trocknen nicht zur Rißbildung neigen. The object of the invention was therefore to provide bar soaps, that are free from the disadvantages described. In particular, it had to be taken into account that new bar soap compositions must also be able to be produced on an industrial scale, d. H. that the compositions are, for example, sufficient but not too have high ductility and do not tend to crack when dried.
Entgegen den aus dem Stand der Technik zu erwartenden Einbußen wurde überraschend festgestellt, daß bei Stückseifen, die bereits Alkylglycoside als Zusatz enthalten, durch einen Zusatz von Talkum eine weitere Verbesserung der physikalischen und anwendungstechnischen Eigenschaften, insbesondere des Wasch- und Kalkseifendispergiervermögens und der Seifenglätte erzielt wird.Contrary to the losses to be expected from the prior art, it was surprising found that with bar soaps that already contain alkyl glycosides as an additive, by a Adding talcum further improves physical and application technology Properties, in particular of the washing and lime soap dispersing ability and the smoothness of the soap is achieved.

Trotz geringen Gesamtgehalts an oberflächenaktiven Substanzen in der Formulierung bleiben die Reinigungsleistung und Schaumentwicklung unbeeinflußt. Das Hautgefühl wird bei der Verwendung dieses Waschstücks selbst ohne zusätzliche Hautpflegesubstanzen entscheidend verbessert.Remain in the formulation despite the low total content of surface-active substances the cleaning performance and foam development unaffected. The skin feeling is at the use of this wash piece even without additional skin care substances improved.
Der Schaum bekommt zudem noch eine bessere Cremigkeit und mehr Volumen, was ebenfalls nicht zu erwarten war. Ein weiterer Vorteil dieser Erfindung ist, das die Verträglichkeit des Waschstücks verbessert wird, da der Gesamtgehalt an oberflächenaktiven Substanzenreduziert wird.The foam also gets better creaminess and more volume, which also was not to be expected. Another advantage of this invention is its compatibility of the wash is improved because the total content of surfactants is reduced becomes.
Die erfindungsgemäßen geformten Seifenprodukte besitzen darüber hinaus nach der mechanischen Verformung eine besonders glatte Oberfläche. Bei der Anwendung erzeugen sie einen cremigen, stabilen Schaum. Der in hartem Wasser gebildete Kalkseifenniederschlag bleibt im Wasser dispergiert und führt nicht zu den grau-schmierigen Belägen auf der Ober fläche von Sanitärobjekten.The shaped soap products according to the invention also have mechanical properties Deformation a particularly smooth surface. When used they generate a creamy, stable foam. The lime soap deposit formed in hard water remains dispersed in the water and does not lead to the gray-greasy deposits on the upper area of sanitary objects.
Talkum ist ein hydratisiertes Magnesiumsilikat der Zusammensetzung 3MgO · 4SO2 · H2O bzw. Mg3(Si4O10) · (OH)2 bzw. Mg6(OH)4[Si8O20] bzw. Mg12[Si16O40], das jedoch Anteile an hydratisiertem Magnesiumalminiumsilikat von bis zu 12 Gew.-% Al2O3, bezogen auf das gesamte Produkt, enthalten kann. Talkum ist ein weißes, meist sehr feines, praktisch geruchloses bis etwas erdig riechendes Pulver, das sich beim Reiben fettig anfühlt, ohne fetthaltig zu sein. Es ist unlöslich in Wasser, kalten Säuren oder Alkalien. Je nach Ursprungsland soll die chemische Reinheit des Talkums (bezogen auf den Gehalt an wasserfreiem Magnesiumsilikat) 93-98 % betragen. Talkum wird zur Herstellung von pharmazeutischen, vor allem aber zur Herstellung kosmetischer Puder, die der Körperpflege dienen, verwendet, ist aber auch zur Tablettenherstellung als Schmier- bzw. Fließmittel geeignet.Talc is a hydrated magnesium silicate with the composition 3MgO · 4SO 2 · H 2 O or Mg 3 (Si 4 O 10 ) · (OH) 2 or Mg 6 (OH) 4 [Si 8 O 20 ] or Mg 12 [Si 16 O 40 ], which, however, can contain proportions of hydrated magnesium aluminum silicate of up to 12% by weight Al 2 O 3 , based on the entire product. Talc is a white, mostly very fine, practically odorless to earthy-smelling powder that feels greasy when rubbed without being fat. It is insoluble in water, cold acids or alkalis. Depending on the country of origin, the chemical purity of the talc (based on the content of anhydrous magnesium silicate) should be 93-98%. Talc is used for the production of pharmaceutical powders, but above all for the production of cosmetic powders that are used for personal hygiene, but is also suitable as a lubricant or flow agent for the production of tablets.
Der Teilchendurchmesser (equivalent spherical diameter) des Talkums sollte im Bereich von 0,5-50 µm liegen. Im allgemeinen haben sich solche Talkumqualitäten bewährt, die nicht mehr als 5 Gew.-% an Teilchen unter 1 µm und nicht mehr als 5 Gew.-% an Teilchen über 50 µm Größe enthalten. Vorzugsweise ist der Anteil an Teilchen, die größer als 40 µm im Durchmesser sind (Siebrückstand), höchstens 2 Gew.-%. Der mittlere Teilchendurchmesser (D 50) liegt bevorzugt bei 5 - 15 µm.The equivalent spherical diameter of the talc should be in the range of 0.5-50 µm.

Der Gehalt an hydratisiertem Magnesiumaluminiumsilikat kann bis zu 60 Gew.-%, berechnet als Al2O3, bis zu 12 Gew.-% liegen.The content of accompanying substances should not exceed 1.6% by weight of Fe 2 O 3 , 1% by weight of CaO and 1% by weight of unbound water (loss of drying at 1050 ° C.). The hydrated magnesium aluminum silicate content can be up to 60% by weight, calculated as Al 2 O 3 , up to 12% by weight.
Erfindungsgemäß vorteilhaft enthalten die geformten Seifenprodukte 1 - 20 Gew.-% Talkum.Advantageously according to the invention, the shaped soap products contain 1-20% by weight talc.
Erfindungsgemäß vorteilhaft enthalten die geformten Seifenprodukte 20-50 Gew.-% nichtionische Tenside.Advantageously according to the invention, the shaped soap products contain 20-50% by weight nonionic Surfactants.
Erfindungsgemäß gegebenenfalls vorteilhaft enthalten die geformten Seifenprodukte (oder Combibars) ebenfalls 5 - 40 Gew.-% an einer Grundseife, beispielsweise einer solchen, deren Seifenbestandteile sich aus Natriumtallowat, Natriumcocoat und Natrium-Palmkemfett-, säuresalz zusammensetzen.According to the invention, the shaped soap products (or Combibars) also 5 - 40% by weight of a base soap, for example one whose Soap constituents consist of sodium tallowate, sodium cocoat and sodium palm stone fat, Put the acid salt together.
Die erfindungsgemäßen geformten Seifenprodukte enthalten darüber hinaus vorteilhaft Wasser in einer Menge von 5-35 Gew.-%. Der Wassergehalt ist einerseits bedingt durch das Herstellungsverfahren, andererseits wirkt er sich günstig auf die Gebraucheigenschaften der Seife aus.The shaped soap products according to the invention also advantageously contain water in an amount of 5-35% by weight. The water content is due to the one hand Manufacturing process, on the other hand, it has a beneficial effect on the properties of use Soap out.
Als Fettsäuren zur Herstellung der Grundseife werden die linearen Fettsäuren mit 12 bis 22 C-Atomen, z. B. die Laurin-, Myristin-, Palmitin-, Stearin-, Arachin- und Behensäure, aber auch die ungesättigten Fettsäuren, z. B. die Palmitolein-, Öl-, Linol-, Linolen-, Arachidon- und Erucasäure verwendet. Bevorzugt werden technische Gemische, wie sie aus pflanzlichen und tierischen Fetten und Ölen erhältlich sind, eingesetzt, z. B. Kokosölfettsäure und Talgfettsäure. Besonders bevorzugt sind Gemische aus Kokos- und Talgfettsäureschnitten, insbesondere ein Gemisch aus 50-80 Gew.-% C16C18- Talgfettsäure und 20-50 Gew.-% C12-C14-Kokosfettsäure.The linear fatty acids with 12 to 22 carbon atoms, e.g. B. the lauric, myristic, palmitic, stearic, arachic and behenic acid, but also the unsaturated fatty acids, for. B. the palmitoleic, oleic, linoleic, linolenic, arachidonic and erucic acid used. Technical mixtures, such as those obtained from vegetable and animal fats and oils, are preferably used, for. B. coconut oil fatty acid and tallow fatty acid. Mixtures of coconut and tallow fatty acid cuts are particularly preferred, in particular a mixture of 50-80% by weight of C 16 -C 18 tallow fatty acid and 20-50% by weight of C 12 -C 14 coconut fatty acid.
Die Fettsäuren werden in Form ihrer Alkaliseife, üblicherweise als Natriumseifen eingesetzt. Die Seifen können aber auch aus den Fetten und Ölen direkt durch Verseifung (Hydrolyse) mit Natronlauge und Abtrennen des Glycerins erzeugt werden. Die erfindungsgemäßen geformten Seifenprodukte enthalten einen zusätzlichen Anteil von 5 - 30 Gew.-% an freien Fettsäuren mit 12-22 C-Atomen. Diese können mit den Fettsäuren der Grundseife identisch sein und durch einen entsprechenden Alkaliunterschuß bei der Verseifung in die Grundseife eingebracht werden. Bevorzugt werden die freien Fettsäuren aber nach der Verseifung und nach dem Aufkonzentrieren, vor der Trocknung, zudosiert.The fatty acids are used in the form of their alkali soap, usually as sodium soaps. The soaps can also be obtained from the fats and oils directly by saponification (hydrolysis) be generated with sodium hydroxide solution and separation of the glycerol. The invention shaped soap products contain an additional proportion of 5-30% by weight free fatty acids with 12-22 carbon atoms. These can be identical to the fatty acids of the basic soap be and by an appropriate alkali deficit in the saponification in the Basic soap can be introduced. However, the free fatty acids are preferred after saponification and added after concentration, before drying.
Zu verwendende nicht-ionische Tenside sind
Zusätzlich zu den nichtionischen Tensiden können die erfindungsgemäßen geformten Seifenprodukte als Bestandteile weiterhin auch kationische, anionische und/oder amphotere bzw. zwitterionische Tenside enthalten.In addition to the nonionic surfactants, the shaped soap products of the invention can as constituents also cationic, anionic and / or amphoteric or zwitterionic surfactants.
Vorteilhaft zu verwendende anionische Tenside sind
Quaternäre Tenside enthalten mindestens ein N-Atom, das mit 4 Alkyl- und/oder Arylgruppen kovalent verbunden ist. Dies führt, unabhängig vom pH Wert, zu einer positiven Ladung. Vorteilhafte quatemäre Tenside sind Alkylbetain, Alkylamidopropylbetain und Alkyl-amidopröpylhydroxysulfain. Kationische Tenside können ferner bevorzugt im Sinne der vorliegenden Erfindung gewählt werden aus der Gruppe der quatemären Ammoniumverbindungen, insbesondere Benzyltrialkylammoniumchloride oder -bromide, wie beispielsweise Benzyldimethylstearylammoniumchiorid, ferner Alkyltrialkylammoniumsalze, beispielsweise beispielsweise Cetyltrimethylammoniumchlorid oder -bromid, Alkyldimethylhydroxyethylammoniumchloride oder -bromide, Dialkyldimethylammoniumchloride oder -bromide, Alkylamidethyltrimethylammoniumethersulfate, Alkylpyridiniumsalze, beispielsweise Lauryl- oder Cetylpyrimidiniumchlorid, Imidazolinderivate und Verbindungen mit kationischem Charakter wie Aminoxide, beispielsweise Alkyldimethylaminoxide oder Alkylaminoethyldimethylaminoxide. Vorteilhaft sind insbesondere Cetyltrimethylammoniumsalze zu verwenden.Quaternary surfactants contain at least one N atom with 4 alkyl and / or aryl groups is covalently linked. Regardless of the pH value, this leads to a positive charge. Advantageous quaternary surfactants are alkyl betaine, alkyl amidopropyl betaine and alkyl amidopropyl hydroxysulfain. Cationic surfactants can also be preferred for the purposes of the present Invention can be selected from the group of quaternary ammonium compounds, in particular benzyltrialkylammonium chlorides or bromides, such as, for example, benzyldimethylstearylammonium chloride, furthermore alkyltrialkylammonium salts, for example for example Cetyltrimethylammonium chloride or bromide, alkyldimethylhydroxyethylammonium chloride or bromides, dialkyldimethylammonium chlorides or bromides, alkylamidethyltrimethylammonium ether sulfates, Alkyl pyridinium salts, for example lauryl or cetyl pyrimidinium chloride, Imidazoline derivatives and compounds with a cationic character such as Amine oxides, for example alkyldimethylamine oxides or alkylaminoethyldimethylamine oxides. Cetyltrimethylammonium salts are particularly advantageous.
Erfindungsgemäß ist die Abwesenheit von Alkyl-(oligo)-Glycosiden. Alkyl-(oligo)-glycoside sind bekannte, im Handel erhältliche nichtionogene Tenside, die nach einschlägigen Verfahren der organischen Chemie zugänglich sind und der Formel R1-O(G)x entsprechen, in der R1 eine primäre C12-C16-Alkylgruppe und (G)x ein Oligoglycosidrest ist, dessen Oligomerisationsgrad x = 1 bis 2 ist. Stellvertretend für das umfangreiche Schrifttum sei hier auf EP-A-0 301 298 und WO-A-90/3977 verwiesen. Die Alkyl-(oligo)-glycoside können sich von Aldosen oder Ketosen mit 5 oder 6 Kohlenstoffen ableiten. Wegen der leichten Zugänglichkeit werden im großtechnischen Maßstab hauptsächlich von Glucose abgeleitete Alkyl-(oligo)-glucoside hergestellt. Abwesenheit dieser Substanzen bedeutet, daß sie allenfalls als Verunreinigungen in der dem erfindungemäßen Combibar zugrundeliegenden Masse zugegen sein dürfen, jedenfalls weniger als 1 Gew.-% betragen müssen.According to the invention is the absence of alkyl (oligo) glycosides. Alkyl (oligo) glycosides are known, commercially available nonionic surfactants which can be obtained by relevant processes in organic chemistry and which correspond to the formula R 1 -O (G) x , in which R 1 is a primary C 12 -C 16 - Alkyl group and (G) x is an oligoglycoside residue whose degree of oligomerization x = 1 to 2. As a representative of the extensive literature, reference is made here to EP-A-0 301 298 and WO-A-90/3977. The alkyl (oligo) glycosides can be derived from aldoses or ketoses with 5 or 6 carbons. Because of the easy accessibility, mainly alkyl- (oligo) -glucosides derived from glucose are produced on an industrial scale.
