Definitions

  • the invention relates to an enzyme-containing hand dishwashing detergent with improved enzyme stability.
  • Common detergents or cleaners on the market contain surfactants to remove dirt and stains.
  • combinations of a plurality of surfactants in particular from the group of anionic, nonionic, cationic and amphoteric surfactants, are used here.
  • These surfactants alone are often unable to remove dirt and stains sufficiently, so that in modern detergents or cleaning agents, other auxiliaries are used.
  • These other excipients include enzymes of various types such as proteases, amylases, cellulases, mannanases, pectate lyases.
  • hydrolytic enzymes such as proteases, amylases or lipases are part of numerous textile or dishwashing detergents because of their direct cleaning action.
  • Detergents or cleaning enzymes are formulated both in solid and in liquid form.
  • the group of solid enzyme preparations includes, in particular, the enzyme granules consisting of several ingredients, which in turn are preferably incorporated into solid washing or cleaning agents.
  • liquid or gel detergents or cleaners frequently contain liquid enzyme preparations, which, unlike the enzyme granules, are much less protected against external influences.
  • German Patent Application DE 20 38 103 (Henkel) teaches the stabilization of enzyme-containing dishwashing detergents by saccharides, while in European Patent EP 646 170 B1 (Procter & Gamble) propylene glycol is disclosed for enzyme stabilization in liquid detergents.
  • a second group of known stabilizers form borax, boric acids, boronic acids or their salts or esters.
  • These include, in particular, derivatives with aromatic groups, for example ortho, meta or para-substituted phenylboronic acids, in particular 4-formylphenylboronic acid (4-FPBA) or the salts or esters of the compounds mentioned.
  • boric acids and boric acid derivatives often have the disadvantage that they form undesirable by-products with other ingredients of a composition, especially detergents or cleaning ingredients, so that they are no longer available for the desired cleaning purpose in the relevant agents or even as an impurity on the Laundry left behind.
  • boric acids or borates are considered to be disadvantageous from an environmental point of view.
  • liquid cleaning compositions which contain from 20 to 70% by weight of water, at least one amylase preparation, at least one
  • Calcium ion source and lactic acid or a lactic acid salt.
  • the invention therefore relates to the use of calcium lactate in enzyme-containing
  • Another object of the invention are enzyme-containing hand dishwashing detergents which contain a) at least one calcium ion source and b) lactic acid or a lactic acid salt.
  • Agents according to the invention are therefore at least one calcium ion source and lactic acid or a lactic acid salt.
  • Preferred lactic acid salts are the salts of the alkali and alkaline earth metals. The proportion by weight of the lactic acid or of the lactic acid salt in the total weight of the
  • Hand dishwashing detergent is preferably 0, 1 to 8 wt .-%, preferably 0, 15 to 5 wt .-%, particularly preferably 0.2 to 2 wt .-% and in particular 0.5 to 1, 5 wt .-%. It is particularly preferred to use calcium lactate as a common source of calcium ions and lactic acid. Enzyme-containing hand dishwashing detergents which contain 0.1 to 8% by weight, preferably 0.15 to 5% by weight, particularly preferably 0.2 to 2% by weight and in particular 0.5 to 1.5% by weight of calcium lactate , based on the total hand dishwashing detergent, are therefore preferred according to the invention. Hand dishwashing detergents are usually liquid agents.
  • liquid agents are understood as meaning those which are flowable under normal conditions of use and whose viscosities can vary within a wide range.
  • the liquid preparations also include gelatinous or pasty agents, which may optionally have additional thickening agents known from the prior art.
  • the liquid agents are based on water.
  • calcium lactate already contributes in relatively small amounts to the stabilization of enzymes. While other known enzyme stabilizers are frequently used in amounts of up to 10% by weight, calcium lactate leads to significant enzyme stabilization even at significantly lower concentrations.
  • An agent according to the invention contains at least one enzyme from one of the known enzymes commonly used in detergents or cleaners.
  • an agent according to the invention contains an amylase and / or a protease;
  • the content of the agent on an amylase if appropriate in combination with a protease, is particularly preferred.
  • the use of calcium lactate is also preferred for increasing the stability of amylases, in particular in liquid and, above all, aqueous hand dishwashing detergents.
  • amylases synonymous terms may be used, for example, 1,4-alpha-D-glucan glucanohydrolase or glycogenase.
  • Preparable amylases according to the invention are preferably .alpha.-amylases.
  • Crucial for determining whether an enzyme is an ⁇ -amylase according to the invention is its ability to hydrolyze a (1-4) -glycoside bonds in the amylose of the starch.

Description

„Enzymhaltiges Handgeschirrspülmittel"  "Enzyme-containing hand dishwashing detergent"
Die Erfindung betrifft ein enzymhaltiges Handgeschirrspülmittel mit verbesserter Enzymstabilität. The invention relates to an enzyme-containing hand dishwashing detergent with improved enzyme stability.
Übliche Wasch- oder Reinigungsmittel des Marktes enthalten Tenside zur Entfernung von Schmutz und Flecken. In der Regel werden hierbei Kombinationen aus mehreren Tensiden, insbesondere aus der Gruppe der anionischen, nichtionischen, kationischen und amphoteren Tenside verwendet. Diese Tenside allein sind häufig nicht in der Lage, Schmutz und Flecken hinreichend zu entfernen, so dass in modernen Wasch- oder Reinigungsmitteln weitere Hilfsstoffe eingesetzt werden. Zu diesen weiteren Hilfsstoffen gehören Enzyme verschiedener Arten wie Proteasen, Amylasen, Cellulasen, Mannanasen, Pektatlyasen. Dem Fachmann sind weitere Enzymklassen bekannt. Insbesondere hydrolytische Enzyme wie Proteasen, Amylasen oder Lipasen sind wegen ihrer unmittelbar reinigenden Wirkung Bestandteil zahlreicher Textil- oder Geschirrreinigungsmittel. Common detergents or cleaners on the market contain surfactants to remove dirt and stains. As a rule, combinations of a plurality of surfactants, in particular from the group of anionic, nonionic, cationic and amphoteric surfactants, are used here. These surfactants alone are often unable to remove dirt and stains sufficiently, so that in modern detergents or cleaning agents, other auxiliaries are used. These other excipients include enzymes of various types such as proteases, amylases, cellulases, mannanases, pectate lyases. The skilled worker is aware of other classes of enzymes. In particular, hydrolytic enzymes such as proteases, amylases or lipases are part of numerous textile or dishwashing detergents because of their direct cleaning action.
Die für den Endverbraucher entscheidende Reinigungswirkung der in Wasch- oder The decisive for the end user cleaning effect of washing or
Reinigungsmitteln eingesetzten Enzyme wird neben der Enzymstruktur in wesentlichem Maße auch durch die Art der Konfektionierung dieser Enzyme und ihrer Stabilisierung gegen Detergents used enzymes in addition to the enzyme structure to a considerable extent by the way the preparation of these enzymes and their stabilization against
Umwelteinflüsse bestimmt. Environmental influences determined.
Wasch- oder reinigungsaktive Enzyme werden sowohl in fester als auch in flüssiger Form konfektioniert. Zur Gruppe der festen Enzymzubereitungen zählen insbesondere die aus mehreren Inhaltsstoffen bestehenden Enzymgranulate, die ihrerseits vorzugsweise in feste Wasch- oder Reinigungsmittel eingearbeitet werden. Flüssige oder gelförmige Wasch- oder Reinigungsmittel enthalten im Gegensatz hierzu häufig flüssige Enzymzubereitungen, wobei diese, anders als die Enzymgranulate gegen äußere Einflüsse weit weniger geschützt sind. Detergents or cleaning enzymes are formulated both in solid and in liquid form. The group of solid enzyme preparations includes, in particular, the enzyme granules consisting of several ingredients, which in turn are preferably incorporated into solid washing or cleaning agents. In contrast, liquid or gel detergents or cleaners frequently contain liquid enzyme preparations, which, unlike the enzyme granules, are much less protected against external influences.
Zur Erhöhung der Stabilität derartiger Enzym-haltiger flüssiger Wasch- oder Reinigungsmittel wurden eine Reihe unterschiedlicher Schutzmaßnahmen vorgeschlagen. So lehrt beispielsweise die deutsche Patentanmeldung DE 20 38 103 (Henkel) die Stabilisierung von Enzym-haltigen Geschirrspülmitteln durch Saccharide, während in dem europäischen Patent EP 646 170 B1 (Procter & Gamble) Propylenglykol zur Enzymstabilisierung in flüssigen Reinigungsmitteln offenbart wird. To increase the stability of such enzyme-containing liquid detergents or cleaners, a number of different protective measures have been proposed. For example, German Patent Application DE 20 38 103 (Henkel) teaches the stabilization of enzyme-containing dishwashing detergents by saccharides, while in European Patent EP 646 170 B1 (Procter & Gamble) propylene glycol is disclosed for enzyme stabilization in liquid detergents.
Als reversible Proteaseinhibitoren sind im Stand der Technik Polyole, insbesondere Glycerin und 1 ,2-Propylenglycol beschrieben. Eine entsprechende technische Offenbarung findet sich beispielsweise in der internationalen Anmeldung WO 02/08398 A2 (Genencor). As reversible protease inhibitors in the prior art polyols, especially glycerol and 1, 2-propylene glycol are described. A corresponding technical disclosure can be found, for example, in international application WO 02/08398 A2 (Genencor).
Die Stabilisierung von Enzymen in wässrigen Reinigungsmitteln durch Calciumsalze wie The stabilization of enzymes in aqueous detergents by calcium salts such as
Calciumformiat, Calciumacetat oder Calciumpropionat beschreibt das US amerikanische Patent 4,318, 818 (Procter & Gamble). Salze mehrwertiger Kationen wie Calciumkationen führen jedoch in wässerigen Systemen, insbesondere in manuellen Geschirrspülmitteln häufig zu Trübungen während der Lagerung. Dieser negative Effekt verstärkt sich bei der Lagerung bei tiefen Calcium formate, calcium acetate or calcium propionate is described in U.S. Patent 4,318,818 (Procter & Gamble). However, salts of polyvalent cations such as calcium cations lead in aqueous systems, especially in manual dishwashing detergents, often cause turbidity during storage. This negative effect increases when stored at low
Temperaturen. Dadurch sind die möglichen Einsatzkonzentrationen limitiert, so dass keine ausreichende enzymstabilisierende Wirkung garantiert werden kann. Temperatures. As a result, the possible use concentrations are limited, so that a sufficient enzyme-stabilizing effect can not be guaranteed.
Eine zweite Gruppe bekannter Stabilisatoren bilden Borax, Borsäuren, Boronsäuren oder deren Salze oder Ester. Darunter sind vor allem Derivate mit aromatischen Gruppen, etwa ortho-, meta- oder para-substituierte Phenylboronsäuren zu erwähnen, insbesondere 4-Formylphenyl-Boron- säure (4-FPBA) beziehungsweise die Salze oder Ester der genannten Verbindungen. A second group of known stabilizers form borax, boric acids, boronic acids or their salts or esters. These include, in particular, derivatives with aromatic groups, for example ortho, meta or para-substituted phenylboronic acids, in particular 4-formylphenylboronic acid (4-FPBA) or the salts or esters of the compounds mentioned.
Letztgenannte Verbindungen als Enzymstabilisatoren sind beispielsweise offenbart in der internationalen Patentanmeldung WO 96/41859 A1 (Novo Nordisk). Allerdings weisen The latter compounds as enzyme stabilizers are disclosed, for example, in international patent application WO 96/41859 A1 (Novo Nordisk). However, wise
beispielsweise Borsäuren und Borsäurederivate oftmals den Nachteil auf, dass sie mit anderen Inhaltsstoffen einer Zusammensetzung, insbesondere Wasch- bzw. Reinigungsmittelinhaltsstoffen, unerwünschte Nebenprodukte bilden, so dass diese in den betreffenden Mitteln nicht mehr für den erwünschten Reinigungszweck zur Verfügung stehen oder sogar als Verunreinigung auf dem Waschgut zurückbleiben. Ferner werden Borsäuren bzw. Borate unter Umweltaspekten als nachteilig betrachtet. For example, boric acids and boric acid derivatives often have the disadvantage that they form undesirable by-products with other ingredients of a composition, especially detergents or cleaning ingredients, so that they are no longer available for the desired cleaning purpose in the relevant agents or even as an impurity on the Laundry left behind. Furthermore, boric acids or borates are considered to be disadvantageous from an environmental point of view.
Die internationale Patentanmeldung WO 201 1/147665 beschreibt flüssige Reinigungsmittel, welche 20 bis 70 Gew.-% Wasser, mindestens eine Amylase-Zubereitung, mindestens eine International Patent Application WO 201 1/147665 describes liquid cleaning compositions which contain from 20 to 70% by weight of water, at least one amylase preparation, at least one
Calciumionenquelle und Milchsäure oder ein Milchsäuresalz enthalten. Calcium ion source and lactic acid or a lactic acid salt.
Es wurde nun gefunden, dass auch enzymhaltige Handgeschirrspülmittel, welche mindestens eine Calciumionenquelle und Milchsäure oder ein Milchsäuresalz enthalten, eine verbesserte It has now been found that enzyme-containing hand dishwashing detergents containing at least one calcium ion source and lactic acid or a lactic acid salt have also been improved
Enzymstabilität aufweisen. Have enzyme stability.
Gegenstand der Erfindung ist daher die Verwendung von Calciumlactat in enzymhaltigen The invention therefore relates to the use of calcium lactate in enzyme-containing
Handgeschirrspülmitteln. Hand dishwashing detergents.
Ein weiterer Gegenstand der Erfindung sind enzymhaltige Handgeschirrspülmittel, welche a) mindestens eine Calciumionenquelle und b) Milchsäure oder ein Milchsäuresalz enthalten. Another object of the invention are enzyme-containing hand dishwashing detergents which contain a) at least one calcium ion source and b) lactic acid or a lactic acid salt.
Überraschenderweise wurde gefunden, dass Calciumlactat eine stabilisierende Wirkung von Enzymen auch in Handgeschirrspülmitteln aufweist. Wesentliche Bestandteile der Surprisingly, it has been found that calcium lactate has a stabilizing effect of enzymes even in hand dishwashing detergents. Essential components of
erfindungsgemäßen Mittel sind daher mindestens eine Calciumionenquelle und Milchsäure oder ein Milchsäuresalz. Bevorzugte Milchsäuresalze sind die Salze der Alkali- und Erdalkalimetalle. Der Gewichtsanteil der Milchsäure bzw. des Milchsäuresalzes am Gesamtgewicht des Agents according to the invention are therefore at least one calcium ion source and lactic acid or a lactic acid salt. Preferred lactic acid salts are the salts of the alkali and alkaline earth metals. The proportion by weight of the lactic acid or of the lactic acid salt in the total weight of the
Handgeschirrspülmittels beträgt vorzugsweise 0, 1 bis 8 Gew.-%, bevorzugt 0, 15 bis 5 Gew.-%, besonders bevorzugt 0,2 bis 2 Gew.-% und insbesondere 0,5 bis 1 ,5 Gew.-%. Es ist besonders bevorzugt, Calciumlactat als gemeinsame Quelle für Calciumionen und Milchsäure einzusetzen. Enzymhaltige Handgeschirrspülmittel, welche 0, 1 bis 8 Gew.-%, bevorzugt 0, 15 bis 5 Gew.-%, besonders bevorzugt 0,2 bis 2 Gew.-% und insbesondere 0,5 bis 1 ,5 Gew.-% Calciumlactat, bezogen auf das gesamte Handgeschirrspülmittel, aufweisen, werden daher erfindungsgemäß bevorzugt. Üblicherweise handelt es sich bei Handgeschirrspülmitteln um flüssige Mittel. Hand dishwashing detergent is preferably 0, 1 to 8 wt .-%, preferably 0, 15 to 5 wt .-%, particularly preferably 0.2 to 2 wt .-% and in particular 0.5 to 1, 5 wt .-%. It is particularly preferred to use calcium lactate as a common source of calcium ions and lactic acid. Enzyme-containing hand dishwashing detergents which contain 0.1 to 8% by weight, preferably 0.15 to 5% by weight, particularly preferably 0.2 to 2% by weight and in particular 0.5 to 1.5% by weight of calcium lactate , based on the total hand dishwashing detergent, are therefore preferred according to the invention. Hand dishwashing detergents are usually liquid agents.
Im Rahmen der vorliegenden Erfindung werden unter flüssigen Mitteln solche verstanden, die unter normalen Anwendungsbedingungen fließfähig sind und deren Viskositäten in einem breiten Rahmen variieren können. Zu den flüssigen Zubereitungen zählen auch gelförmige oder pastöse Mittel, welche gegebenenfalls zusätzliche aus dem Stand der Technik bekannte Verdickungsmittel aufweisen können. In einer weiter bevorzugten Ausführungsform der Erfindung beruhen die flüssigen Mittel auf wässeriger Basis. In the context of the present invention, liquid agents are understood as meaning those which are flowable under normal conditions of use and whose viscosities can vary within a wide range. The liquid preparations also include gelatinous or pasty agents, which may optionally have additional thickening agents known from the prior art. In a further preferred embodiment of the invention, the liquid agents are based on water.
Vorteilhafterweise hat es sich herausgestellt, dass Calciumlactat bereits in relativ geringen Mengen zur Stabilisierung von Enzymen beiträgt. Während andere bekannte Enzymstabilisatoren häufig in Mengen bis zu 10 Gew.-% eingesetzt werden, führt Calciumlactat bereits in deutlich geringeren Konzentrationen zu einer signifikanten Enzymstabilisierung. Advantageously, it has been found that calcium lactate already contributes in relatively small amounts to the stabilization of enzymes. While other known enzyme stabilizers are frequently used in amounts of up to 10% by weight, calcium lactate leads to significant enzyme stabilization even at significantly lower concentrations.
Ein erfindungsgemäßes Mittel enthält mindestens ein Enzym aus einer der bekannten, in Waschoder Reinigungsmitteln üblicherweise eingesetzten Enzyme. In einer bevorzugten An agent according to the invention contains at least one enzyme from one of the known enzymes commonly used in detergents or cleaners. In a preferred
Ausführungsform der Erfindung enthält ein erfindungsgemäßes Mittel eine Amylase und/oder eine Protease; dabei ist der Gehalt des Mittels an einer Amylase, gegebenenfalls in Kombination mit einer Protease insbesondere bevorzugt. Dementsprechend bevorzugt ist auch die Verwendung von Calciumlactat zur Erhöhung der Stabilität von Amylasen, insbesondere in flüssigen und vor allem wässerigen Handgeschirrspülmitteln. Embodiment of the invention, an agent according to the invention contains an amylase and / or a protease; In this case, the content of the agent on an amylase, if appropriate in combination with a protease, is particularly preferred. Accordingly, the use of calcium lactate is also preferred for increasing the stability of amylases, in particular in liquid and, above all, aqueous hand dishwashing detergents.
Für Amylasen können synonyme Begriffe verwendet werden, beispielsweise 1 ,4-alpha-D-Glucan- Glucanohydrolase oder Glycogenase. Erfindungsgemäß konfektionierbare Amylasen sind vorzugsweise α-Amylasen. Entscheidend dafür, ob ein Enzym eine α-Amylase im Sinne der Erfindung ist, ist deren Fähigkeit zur Hydrolyse von a(1-4)-Glykosidbindungen in der Amylose der Stärke. For amylases, synonymous terms may be used, for example, 1,4-alpha-D-glucan glucanohydrolase or glycogenase. Preparable amylases according to the invention are preferably .alpha.-amylases. Crucial for determining whether an enzyme is an α-amylase according to the invention is its ability to hydrolyze a (1-4) -glycoside bonds in the amylose of the starch.
Erfindungsgemäß konfektionierbare Amylasen sind beispielsweise die a-Amylasen aus Bacillus licheniformis, aus Bacillus amyloliquefaciens oder aus Bacillus stearothermophilus sowie insbesondere auch deren für den Einsatz in Wasch- oder Reinigungsmitteln verbesserte Amylases which can be synthesized according to the invention are, for example, the a-amylases from Bacillus licheniformis, from Bacillus amyloliquefaciens or from Bacillus stearothermophilus and in particular also improved for use in detergents or cleaners

APG sind nichtionische Tenside und stellen bekannte Stoffe dar, die nach den einschlägigen Verfahren der präparativen organischen Chemie erhalten werden können. Die Indexzahl x gibt den Oligomerisierungsgrad (DP-Grad) an, d.h. die Verteilung von Mono- und Oligoglykosiden, und steht für eine Zahl zwischen 1 und 10. Während x in einer gegebenen Verbindung stets ganzzahlig sein muss und hier vor allem die Werte x = 1 bis 6 annehmen kann, ist der Wert x für ein bestimmtes Alkylglykosid eine analytisch ermittelte rechnerische Größe, die meistens eine gebrochene Zahl darstellt. Vorzugsweise werden Alkylglykoside mit einem mittleren Oligomerisierungsgrad x von 1 ,1 bis 3,0 eingesetzt.

Eine Veränderung des Dicarbonsäure(salz)-Gehaltes kann - insbesondere in Mengen oberhalb 2 Gew.-% - zu einer klaren Lösung der Inhaltsstoffe beitragen. Ebenfalls ist innerhalb gewisser Grenzen eine Beeinflussung der Viskosität der Mischung durch dieses Mittel möglich. Weiterhin beeinflusst diese Komponente die Löslichkeit der Mischung. Diese Komponente wird besonders bevorzugt bei hohen Tensidgehalten eingesetzt, insbesondere bei Tensidgehalten oberhalb 30 Gew.-%. A change in the dicarboxylic acid (salt) content can - especially in amounts above 2 wt .-% - contribute to a clear solution of the ingredients. Also, within certain limits, influencing the viscosity of the mixture by this means is possible. Furthermore, this component influences the solubility of the mixture. This component is particularly preferably used at high surfactant contents, in particular at surfactant contents above 30 wt .-%.

Der pH-Wert des erfindungsgemäßen flüssigen Mittels kann aber auch mittels üblicher pH- Regulatoren, beispielsweise Säuren wie Mineralsäuren oder Citronensäure und/oder Alkalien wie Natrium- oder Kaliumhydroxid, eingestellt werden, wobei - insbesondere bei gewünschter Haut- und Handverträglichkeit - ein Bereich von 4 bis 9, vorzugsweise 5 bis 8,5 und insbesondere 5,5 bis 8,0, bevorzugt ist. Es hat sich gezeigt, dass das enzymhaltige Handgeschirrspülmittel, welches Calciumlactat als Enzymstabilisator enthält, bei pH-Werten oberhalb von 7 zu besonders hohe Enzymaktivitäten und damit Enzymstabilitäten auch nach einer Lagerung der Mittel bei 30 °C führen. Erfindungsgemäße Mittel mit einem pH-Wert oberhalb von 7 werden daher ganz besonders bevorzugt. Zur Einstellung und/oder Stabilisierung des pH-Werts kann das erfindungsgemäße Mittel ein oder mehrere Puffer-Substanzen (INCI Buffering Agents) enthalten, üblicherweise in Mengen von 0,001 bis 5 Gew.-%, vorzugsweise 0,005 bis 3 Gew.-%, insbesondere 0,01 bis 2 Gew.-%, besonders bevorzugt 0,05 bis 1 Gew.-%, äußerst bevorzugt 0, 1 bis 0,5 Gew.-%, beispielsweise 0,2 Gew.-%.

Besonders bevorzugte Puffer- Substanzen sind die Citronensäure bzw. die Citrate, insbesondere die Natrium- und Kaliumeitrate, beispielsweise Trinatriumcitrat-2 H20 und Trikaliumcitrat H20. However, the pH of the liquid agent according to the invention can also be adjusted by means of customary pH regulators, for example acids such as mineral acids or citric acid and / or alkalis such as sodium or potassium hydroxide, wherein - in particular with the desired skin and hand tolerance - a range of 4 to 9, preferably 5 to 8.5 and in particular 5.5 to 8.0, is preferred. It has been found that the enzyme-containing hand dishwashing detergent, which contains calcium lactate as enzyme stabilizer, at pH values above 7 lead to particularly high enzyme activities and thus enzyme stabilities even after storage of the agent at 30 ° C. Agents of the invention having a pH above 7 therefore become very particular prefers. For adjusting and / or stabilizing the pH, the agent according to the invention may contain one or more buffer substances (INCI Buffering Agents), usually in amounts of 0.001 to 5 wt .-%, preferably 0.005 to 3 wt .-%, in particular 0 , 01 to 2 wt .-%, particularly preferably 0.05 to 1 wt .-%, most preferably 0, 1 to 0.5 wt .-%, for example, 0.2 wt .-%. Preference is given to buffer substances which are at the same time complexing agents or even chelating agents (INCI chelating agents). Particularly preferred buffer substances are the citric acid or the citrates, in particular the sodium and potassium conduction rates, for example trisodium citrate-2 H 2 O and tripotassium citrate H 2 O.
