Description
Herstellung einer lagerbeständigen Making a shelf stable
Öl-in-Wasser-Emulsion für kosmetische Zwecke Die Erfindung betrifft die Herstellung einer kosmetischen beständigem Öl-in-Wasser-Emulsion (O/W-Emulsion) aus hautpflegenden Ölen, anionenaktiven Emulgatoren und oder nichtionogenen Emulgatoren unter Zusatz von natürlichem Bienenwache oder synthetischen Produkten, die der Zusammensetzung des natürlichen Bienenwachses weitgehend ähneln und unter Zusatz von Estern ein- oder mehrbasischer Garbonsäuren mit mindestens 2, höchstens 6 C-Atomen mit niederen Alkoholen, mit einem Gehalt der wässerigen Phase von über 50%. Emulsionen in dieser Zusammensetzung haben die an sich bekannte Fähigkeit von Carbcnsäuren und deren Estern mit niederen Alkoholen, die Körpergeruchsbildung zu behindern. Oil-in-water emulsion for cosmetic purposes The invention relates to the production of a cosmetic permanent oil-in-water emulsion (O / W emulsion) from skin-caring oils, anionic emulsifiers and / or non-ionic emulsifiers with the addition of natural bee guard or synthetic products to the composition of natural beeswax and, with the addition of esters, or polybasic carboxylic acids with at least 2, at most 6 carbon atoms with lower Alcohols with an aqueous phase content of over 50%. Emulsions in this Composition have the per se known ability of carbic acids and their Esters with lower alcohols to prevent the formation of body odor.
Die Fähigkeit von Carbonsäuren und deren Estern, die Körpergeruchsbildung zu unterdrücken, ist seit Jahrhunderten z,B.The ability of carboxylic acids and their esters to produce body odor to suppress has been for centuries e.g.
in Form der Anwendung des Toilettenessige bekannt. Ester von Carbonsäuren für diesen Zweck anzuwenden, ist in wasserfreien Zubereitungn bekannt (DO 2418338). Die praktische Anwendung in wässerigen Emulsionen, in weichen eine hautpflegende und hautschützende Wirkung mit einer deodorierenden Säure-Wirkung ohne starke Bactericide und ohne adstringierende Zusätze verbunden wird, schleitert jedoch deren, daß größere Mengen einer freien Carbonsäure biei kosmetischer Anwendung zu Hautl1nverträglichkeiten führen können. Wird einer üblichen Emulsion der Ester einer Carbonsäure einemulgiert, welcher auf der Haut durch Enzyneinwirkung zur Carbonsäure gespalten wird, dann erleidet der Ester in einer wasserreichen O/W-Emulsion ohne Alkoholzusatz oder ohne den erfindungsgemäßen Zusatz beim Lagertest eine Spaltung unter Bildung der freien Carbonsäure, .known in the form of the use of toilet vinegar. Esters of carboxylic acids Use for this purpose is known in anhydrous preparations (DO 2418338). The practical application in aqueous emulsions, in soft a skin care and skin-protecting effect with a deodorizing acid effect without strong bactericides and is connected without astringent additives, but theirs that bigger ones Quantities of a free carboxylic acid for cosmetic use on skin incompatibilities being able to lead. If the ester of a carboxylic acid is emulsified in a conventional emulsion, which on the skin is split into carboxylic acid by the action of enzymes, then the ester suffers in a water-rich O / W emulsion without or without the addition of alcohol the additive according to the invention in the storage test cleavage with formation of the free Carboxylic acid,.
Wodurch die Hautverträglichkeit und auch - durch Verindebunt der Ionenkonzentration - die physikalische Bestandigkeit der Emulsion abnimmt. Die Fähigkeit der Wasserphase einer O/W-Emulsion, hydrolysierend auf leicht verseifbare Carbonsäureester mit 2 bis 6 C-Atomen, verestsrt Nit niederen Alkoholen, welche in der ölphase der O/W-Emulsion gelöst sind, zu wirken, kan durch bestimmte erfindungsgemäße Zusätze vermindert werden. Solche Zusätze sind Bienenwachs oder künstlich hergestellte Produkte ähnlicher Zusammensetzung, die von ihrer Konzentration her einen oder mehrere lipophile Kohlenwasserstoffreste mit mindestens 16 C-Atomen und nur eine hydrophile Gruppe, z.B.By which the skin compatibility and also - by combining the ion concentration - the physical stability of the emulsion decreases. The ability of the water phase an O / W emulsion, hydrolyzing to easily saponifiable Carboxylic acid ester with 2 to 6 carbon atoms, Nit esterifies lower alcohols, which are in the oil phase of the O / W emulsion are dissolved, can be effective by certain additives according to the invention be reduced. Such additives are beeswax or man-made products of a similar composition, the concentration of which is one or more lipophilic Hydrocarbon radicals with at least 16 carbon atoms and only one hydrophilic group, e.g.
eine Carbonsäureestergruppe, eine Hydroxylgruppe, eine Carboxylgruppe im Molekül haben, z.B. Myricinsäure, Myricylpalmitat, Cerotinalkohol. Die beständigkeitserhöhende Wirkung solcher Verbindungen auf eine O/W-Emulsion der vorgenannten Zusammensetzung kann durch die Ausbildung einer Barriere an der Grenyfläche der t/W-Emulsion im Bereich der Ölphase erklärt werden.a carboxylic ester group, a hydroxyl group, a carboxyl group have in the molecule, e.g. myricic acid, myricyl palmitate, cerotin alcohol. The resistance-increasing one Effect of such compounds on an O / W emulsion of the aforementioned composition can be achieved through the formation of a barrier on the greny surface of the t / w emulsion in the Area of the oil phase to be explained.
Beispiel 1 Man bereitet eine kosmetische 0/W-Emulsion durch Erschmelzen einer Ölphase bei 720C mit folgender Zusammensetzung: Olivenöl 2,0 Gew.% Glycerinmonostearat 6,0 Polyoxyäthylen-20-stearat 1, 5 Polyoxyäthylen-24-glycerinmonostearat 1,5 Bienenwachs 2,0 Cetylalkohol 1,0 Isopropylpalmitat 5,0 Paraffinöl 5,0 Nach Herstellung einer homogenen Schmelze von ??0 wird der pH-Wert auf 6,2 eingestellt. Zuletzt weiden noch 3% Citronensäuretriäthylester zugegeben.Example 1 A cosmetic 0 / W emulsion is prepared by melting an oil phase at 720C with the following composition: olive oil 2.0 wt.% glycerol monostearate 6.0 polyoxyethylene 20 stearate 1.5 polyoxyethylene 24 glycerol monostearate 1.5 beeswax 2.0 Cetyl alcohol 1.0 Isopropyl palmitate 5.0 Paraffin oil 5.0 After making a homogeneous melt of ?? 0, the pH is adjusted to 6.2. Last graze another 3% citric acid triethyl ester was added.
Nun wird unter kräftigem Rühren eine auf 75°C erwärmte Lösung von 67,5% Wasser, 5% Propylenglykol und 0,5% Konservierungsmittel innerhalb einer Stunde zugegeben und die entstandene Emulsion bis zum Abkühlen auf 300C gerührt.Now, with vigorous stirring, a heated to 75 ° C solution of 67.5% water, 5% propylene glycol and 0.5% preservative within one hour added and the resulting emulsion stirred until it cools to 300C.
Die gebildete Emulsion wies nach 8-monatiger Lagerung bei 25,0 noch keine pH-Veränderung auf, die die Bildung von freier Citronensäure anzeigt.The emulsion formed still showed after storage at 25.0 for 8 months no change in pH indicating the formation of free citric acid.
Wird eine ähnlich zusammengesetzte Emulsion bereitet, bei welcher das Bienenwachs weggelassen wurde, so verändert'sich der pH-Wert bei gleichlanger Lagerung zu sauberen pH-Werten, wodurch eine Beeinträchtigung der kosmetischen Eigenschaften resultiert.If a similarly composed emulsion is prepared, in which the beeswax has been omitted, the pH value changes for the same length of time Storage at clean pH values, thereby impairing the cosmetic properties results.
Beispiel 2 Man bereitet eine kosmetische 0/W-Emulsion durch Erschmelzen einer Ölphase bei 730C mit folgender Zusammensetzung: Avocadoöl 2,0 Gew.% Glycerinmono-und-distearat 6,0 Polyoxyäthylen-24-glycerinmonostearat 4,o Melissylpalmitat 3,0 Cerotinsäure 0,5 Melissylalkohol 1,5 Isopropylmyristat 5,0 Paraffinöl 5,0 Nach Herstellung einer homogenen Schmelze wird der pH-Wert auf 6,8 eingestellt und 3% Milchsäure-n-propylester zugesetzt.Example 2 A cosmetic 0 / W emulsion is prepared by melting an oil phase at 730C with the following composition: avocado oil 2.0% by weight glycerol mono- and distearate 6.0 polyoxyethylene-24-glycerol monostearate 4, o melissyl palmitate 3.0 cerotic acid 0.5 Melissyl alcohol 1.5 Isopropyl myristate 5.0 Paraffin oil 5.0 After making a homogeneous melt, the pH is adjusted to 6.8 and 3% lactic acid n-propyl ester added.
Nun wird eine auf 75°C gebrachte Wasserphase bestehend aus 4% Propylenglykol, 65,5% Wasser und 0,5% Konservierungsmittel unter kräftigem Rühren zugemischt und die Emulsion bis zum Erkalten gerührt.Now a water phase brought to 75 ° C consisting of 4% propylene glycol, 65.5% water and 0.5% preservative mixed in with vigorous stirring and the Emulsion stirred until cool.
Nach 8-monatiger Lagerung wies die Emulsion keine pH-Voränderung auf.After 8 months of storage, the emulsion showed no pre-change in pH.
Wird eine Vergleichsemulsion ohne diese erfindungsgemäßen Zusätze bereitet, so fällt der pH-Wert bei gleicher Lagerung.Is a comparison emulsion without these additives according to the invention prepared, the pH value falls with the same storage.
