Description
Verfahren zur Herstellung von Emulsionen Die Erfindung betrifft ein Verfahren zur Herstellung von beständigen, vorzugsweise Öl-in-Wasser-Emulsionen mit Hilfe von Estern mehrwertiger Alkohole, welche mindestens eine freie Hydroxylgruppe enthalten, als Emulgatoren.Process for the preparation of emulsions The invention relates to a Process for the production of stable, preferably oil-in-water emulsions with the help of esters of polyhydric alcohols, which have at least one free hydroxyl group contained as emulsifiers.
Die Herstellung derartiger Emulsionen, bei denen man entweder Öl oder Wasser oder beide Stoffe zusammen als Grundstoff benutzt, sind bereits bekannt. So hat man z. B. bereits Schmieröle dadurch verbessert, daß man sie mit Estern mehrwertiger Alkohole mit höher molekularen Fettsäuren emulgierte, oder man hat auch bereits Emulsionen von Triglyzeriden und Kohlenwasserstoffen mit Wasser dadurch verbessert, daß man sie zusammen mit den genannten Estern herstellte. The production of such emulsions, in which either oil or water or both substances used together as a raw material are already known. So one has z. B. already improved lubricating oils by making them polyvalent with esters Alcohols with higher molecular weight fatty acids emulsified, or one already has Emulsions of triglycerides and hydrocarbons with water are improved by that they were made together with the esters mentioned.
In beiden Fällen entstanden aber nur äußerst unbeständige Emulsionen.In both cases, however, only extremely unstable emulsions were formed.
Man hat ferner bereits alkoholische Seifen, z. B. Glyzerinölseifen, hergestellt, deren besondere Wirkung für das Lösen von Kohlenwasserstoffen darauf zurückgeführt wurde, daß sich höher molekulare Alkohole in den Seifen befanden. Um die Herstellung solcher Seifen handelt es sich aber im vorliegenden Falle nicht, sondern um die Herstellung von Emulsionen aus Estern mehrwertiger Alkohole mit höher molekularen : Fettsäuren mit Wasser oder wässerigen Lösungen, wobei die Emulgierung gemäß der Erfindung in Gegenwart geringer Mengen alkalisch reagierender, vorzugsweise seifenartiger Stoffe mit Wasser oder wässerigen Lösungen vorgenommen wird. You also have alcoholic soaps such. B. glycerine oil soaps, manufactured whose special action for dissolving hydrocarbons on it was attributed to the fact that there were higher molecular weight alcohols in the soaps. The present case does not concern the production of such soaps, but about the production of emulsions from esters of polyhydric alcohols with higher molecular: fatty acids with water or aqueous solutions, whereby the emulsification according to the invention in the presence of small amounts of alkaline reacting, preferably soap-like substances are made with water or aqueous solutions.
Derartige Emulsionen sind selbst bei hoher Temperatur äußerst beständig. Sie haben bei geeigneter Konzentration salbenartigen Charakter und können z. B. als Grundlage für die Herstellung kosmetischer Präparate dienen. Statt des Wassers kann man bei der Herstellung der Emulsionen auch wässerige Lösungen der versclliedensten Stoffe verwenden. Such emulsions are extremely stable even at high temperatures. With a suitable concentration, they have an ointment-like character and can, for. B. serve as the basis for the manufacture of cosmetic preparations. Instead of the water one can also use aqueous solutions of the most varied of these in the preparation of the emulsions Use fabrics.
Die Glykolester der höher molekularen Fettsäuren kann man z. B. in der Weise herstellen, daß man Alkylenoxyde mit Fettsäuren bzw. mit solche enthalteilden Gemischen, z. B. natürliche Fette oder Öle, und zwar in Gegenwart geringer Mengen von Alkalisalzel1 dieser Säuren als Katalysator, umsetzt. Im Reaktionsprodukt sind dann neben den Glykolestern die Alkalisalze der entsprechende Fettsäuren enthalten, und man kann nun durch Behandeln des Produktes mit Wasser sofort eine salbenartige Emulsion herstellen, ohne daß es erst notwendig wäre, alkalisch reagierende Stoffe besonders zuzusetzen. The glycol esters of the higher molecular weight fatty acids can be z. Am produce the way that one enthalteilden alkylene oxides with fatty acids or with such Mixtures, e.g. B. natural fats or oils, in the presence of small amounts of alkali salts of these acids as a catalyst. Are in the reaction product then contain the alkali salts of the corresponding fatty acids in addition to the glycol esters, and by treating the product with water one can immediately make an ointment-like Produce emulsion without the need to use alkaline substances especially to add.
Auch kann man dem betreffenden Ester vor, während oder nach der Emulgierung feste oder flüssige Stoffe, z. B. Riechstoffe, ätherische Ole, Alkohol usw., zusetzen, die da mit in die Emulsion eingehen. The ester in question can also be used before, during or after emulsification solid or liquid substances, e.g. B. Add fragrances, essential oils, alcohol, etc., that go into the emulsion.
Beispiel I 5 kg Stearinsäure werden nach Zusatz von 50 g NaOH mit I kg Äthylenoxyd ; yd mehrere Stunden im Autoklaven erhitzt. Das auE diese Weise erhaltene Produkt wird mit 18 kg einer 25%igen Glyzerinlösung bei einer 'Pemperatur von /io bis 700 emulgiert. Nach dem Erkalten ergibt sich eine schöne, weiche, weiße Salbe, die gegen rotes Lackmuspapier keine basische Reaktion mehr zeigt. Example I 5 kg of stearic acid are added after adding 50 g of NaOH I kg of ethylene oxide; yd heated in the autoclave for several hours. That way too obtained product is with 18 kg of a 25% glycerine solution at a 'Temperature emulsified from / io to 700. After cooling, the result is a nice, soft, white color Ointment that no longer shows any basic reaction to red litmus paper.
Beispiel 2 80 Teile einer 25 %igen Glyzerinlösung werden auf 75° erhitzt und in diese 20 Teile geschmolzener Glykolmonostearinsäureester, der mit 6 01o Kaliumstearat versetzt wurde, in dünnem Strahl unter ständigem Rühren eingegossen. Das Rühren wird bis zum Erkalten fortgesetzt. Example 2 80 parts of a 25% strength glycerine solution are heated to 75 ° heated and in this 20 parts of molten glycol monostearic acid ester, which with 6 01o potassium stearate was added, poured in a thin stream with constant stirring. Stirring is continued until it has cooled down.
Beispiel3 20 Teile Glyzerinmonostearinsäureester werden mit o, 6 Teilen Triäthanolaminstearat zusammengeschmolzen. In die heiße Schmelze bringt man 20 Teile weiße Vaseline ein und gießt unter ständigem Rühren etwa 70° heiße Lösung von 10 Teilen Glyzerin mit 50 Teilen Wasser zu. Es wird bis zum Erkalten gerührt. Example 3 20 parts of glycerol monostearic acid ester are mixed with 0.6 Parts of triethanolamine stearate melted together. You bring it into the hot melt 20 parts of white vaseline and pour in the solution at a temperature of about 70 ° while stirring constantly of 10 parts of glycerine with 50 parts of water. It is stirred until it cools.
Beispiel 4 Technische Hartfettsäure wird mit Glyzerin verestert, bis die Säurezahl des entstandenen Produkts etwa 25 beträgt. Man gibt darauf dem Ester I 01o seines Gewichts technisches Kaliumhydroxyd in 50%iger Lösung hinzu, wodurch die Säurezahl entsprechend zurückgeht, und löst nun 20 Teile Olivenöl in 30 Teilen des mit Alkali versetzten Hartfettsäureesters unter Erhitzen auf etwa 80°. Example 4 Technical hard fatty acid is esterified with glycerine, until the acid number of the resulting product is about 25. You give it to the Ester I 01o of its weight technical potassium hydroxide in 50% solution added, whereby the acid number decreases accordingly, and now dissolves 20 parts of olive oil in 30 parts of the hard fatty acid ester mixed with alkali with heating to about 80 °.
Die geschmolzene Masse gießt man in 50 Teile Wasser von 700 und rührt, bis eine schöne gleichmäßige Emulsion entstanden ist.The melted mass is poured into 50 parts of water from 700 and stirred, until a nice, even emulsion is created.
Beispiel 5 8-kg des nach Beispiel I erhaltenen Glykolstearinsäureesters werden mit 20 kg Vaseline bei 700 zusammengeschmolzen. Dann trägt man 68 kg Wasser in die Mischung ein, rührt bis zum Abkühlen auf etwa 50° und gibt 6 kg eines mäßig steifen Polysaccharidgels, z. B. Tragant, Gummiharz, wie er z. B. unter dem Namen Physiol-erhältlich ist, Stärke o. dgl. zu. Man rührt bis zum Erkalten. Example 5 8 kg of the glycol stearic acid ester obtained according to Example I. are melted together with 20 kg of Vaseline at 700. Then you carry 68 kg of water into the mixture, stir until it cools to about 50 ° and give 6 kg of a moderately rigid polysaccharide gels, e.g. B. tragacanth, gum resin, as z. B. under the name Physiol is available, starch or the like. One stirs until it cools.
Das Präparat ist eine weiße Emulsion von hoher Beständigkeit, die sich z. B. zum Fetten von feinen Ledersorten - eignet. The preparation is a white emulsion of high persistence that z. B. for greasing fine types of leather - suitable.
