Description

Territory of invention

The Invention relates to liquid Detergent compositions consisting of at least two sub-compositions exist, which are kept separate from each other in a single container be, which comprises at least two chambers, and which in use are mixed, a sub-composition of a peroxide bleaching compound includes.

The Compositions are for determines the cleaning and disinfection of household surfaces and are particularly good for the use on surfaces customized, the non-horizontal (i.e. oblique or vertical), e.g. found in bathrooms and toilets can be.

background the invention

compositions for use on non-horizontal surfaces that clean and disinfect can, currently include solutions of alkali metal hypochlorite to be poured, sprayed or sprayed onto the surface. Such solutions are thickened to prevent them from running off the surface too quickly. Especially for Toilet cleaning purposes are often packaged in containers on the market brought which with a spout are provided so that they by pressing the container of the surface supplied can be. Sometimes there are such spouts attached to the container in such a way that the The liquid splashed by pressing generated, can be directed more easily to corners or under edges, which are not easily accessible in other ways.

On The problem with such compositions is that hypochlorite has an unpleasant smell and if it is accidentally with mixed with an acidic product, toxic amounts of chlorine gas can release. Other bleaching agents are known, particularly Peroxides. However, peroxides are common either unstable or show when stored in formulations poor bleaching behavior at a pH at which they are stable in storage are.

toothpastes and peroxide-based hair bleach compositions are considered weak acidic peroxide solutions or gels have been formulated with separate weakly alkaline solutions or pastes mixed immediately before use. The Known advantage of this product form is that the peroxide is more stable to decomposition under acidic conditions, however is more effective than bleach under alkaline conditions.

• (a) 0,5 – 50 Gew.-% Wasserstoffperoxid,
• (b) Alkali mit einer Alkalinität von 0,1 – 50 % auf der Basis von Natriumhydroxid,
• (c) oberflächenaktives Mittel in (a) oder (b) und
• (d) Terpenalkohol/cyclischer Terpenalkohol in (a) und (b).

Other two-part peroxide-based compositions are disclosed in JP-A-60/038497 (LION BRANDS), which relates to a foaming two-part drain cleaner composition comprising:

• (a) 0.5-50% by weight hydrogen peroxide,
• (b) alkali with an alkalinity of 0.1-50% based on sodium hydroxide,
• (c) surfactant in (a) or (b) and
• (d) Terpene alcohol / cyclic terpene alcohol in (a) and (b).

The Compositions (a) and (b) which include the surfactants and terpene dosed in succession or simultaneously into a toilet bowl and enter the drainpipes where the composition unites foam body generated that acts so that he the drain pipe cleans or clogged if necessary of the drain pipe eliminated.

Other Forms of simultaneous delivery of two components are known. For example, US-A-3,760,986 discloses a dispensing bottle for dispensing two separate fluids at a common point. Such one Bottle is with an opening formed at the top and a partition, which is divided by the Interior of the bottle extends to delimit two compartments two reservoirs for Provide fluids. The disclosed device further comprises a pumping device to simultaneously separate fluid from each compartment Pull pipes and pull the fluid to a common point escape allow. This device enables the existence alkaline and an acidic material stored separately and out sprayed onto a common point in a single unit.

WO 95/16023 discloses a container comprising two compartments or reservoirs, one containing a liquid acid or neutral composition surrounding a peroxide compound summarizes, and the other contains a liquid alkaline composition. The container is provided with a spray system which is capable of producing either a single spray from a mixture of the two components or two simultaneous sprays of each component which are directed to the same point on a surface, after which the components are on the surface Mix. The product is supplied as fine droplets that coalesce on the surface, which makes mixing the two compositions easy and complete. It is described that the compositions can be thickened as is, or that they can contain a thickening system that thickens when mixed. The thickening system is especially designed to improve the spray properties and prevent inhalation irritation caused by very fine droplets. The examples show that both components must be thickened before spraying.

The WO 97/31087 discloses a container, which comprises two chambers or reservoirs, one or one of which a liquid Contains composition which comprises one peroxide bleach, and the other a liquid Contains composition which comprises a builder or a chelating agent, at least one of these liquids contains a pH adjusting agent which when mixing the liquids brings the pH of the mixture to a level where the peroxide bleach effectively cleans and is stable. Preferably the peroxide is bleach either a peracid or a persalt and the pH is between 9.0 and 11.5. The two liquid Compositions are mixed as they are applied to the surface, preferably by a spray system. A similar System is described in WO 98/23533, in which a combination of hydrogen peroxide and a tertiary N-alkylammonium acetonitrile salt from one chamber and an alkaline solution can be supplied from another chamber by spraying a surface can.

This State-of-the-art two-component peroxide cleaning systems have the disadvantage that a spray system is only able to deliver a limited amount of product to a surface and is unable to reach hard-to-reach places since the container generally must be kept vertical. That is why they are for toilet cleaning purposes less suitable. About that are also spray systems, like spray heads with sear and pump spray devices, relatively expensive, especially those for multi-compartment containers are suitable.

Short description the invention

It is therefore an object of the present invention, liquid detergent compositions for hard surfaces to provide which include a peroxide bleach in which Storage are stable and yet good cleaning and disinfection when applied to a surface.

It is another object of the invention, liquid detergent compositions for hard surfaces Provide that easily using a non-spray delivery system applied to a surface can be and on the surface are thick enough for cleaning of non-horizontal surfaces, especially toilets, to be suitable.

It Another object of the present invention is liquid detergent compositions for hard surfaces provide in which components are in the presence of each other are not stable in storage until the time of delivery of the composition on the surface be kept separate.

The Invention also provides a container ready, which comprises two or more chambers, each with a Outlet opening for dispensing the content of each chamber is provided and which together form part of a Non-spray delivery system form, the container the liquid described above Partial compositions holds.

detailed Description of the invention

For the purposes of this invention is a "partial composition" as a component or a mixture of several but not all components of the Final composition defined where the component or mixture is held in a separate chamber of the container which contains the total composition. Two or more sub-compositions together make up the final detergent composition according to the present Invention.

On Container, that for holding the detergent compositions according to the invention is suitable, has at least as many separate chambers as the number of sub-compositions, which is the total composition form. Such a container can be an outer wall have, which encloses all chambers, which are separated from each other partitions inside the container are separated, or alternatively it can be a plurality of separate ones containers be composed, which are equivalent to the chambers and by any external means, like a connecting section of the walls or a surrounding section adhesive sleeve are held together in such a way that they are held as a container and can be handled. A dispensing system is provided in which each chamber has a provided an outlet opening through which the partial composition is released. This outlet can all lead to a separate mixing chamber in which the dispensed Amounts of the sub-compositions immediately before going through a discharge opening applied to the surface in the mixing chamber, mix. Alternatively, you can the outlet openings all to the outside in such a way of the container to lead, that the delivered quantities of the partial compositions all at the same time the same area the surface can be applied so that you mix while applied them to the surface be or immediately after application on the surface. For this The purpose is the outlet openings generally arranged in close proximity to each other, so that all Partial compositions in one operation on the same area of the surface poured, sprayed. The outlet openings can be made with a nozzle system be provided, which is designed so that the mixing of the sub-compositions when leaving the container further improved. Delivery systems such as those described above and the like "Non-spray delivery systems" are known in the art. They are generally characterized by the absence of so-called "trigger lever spray heads or pump spray heads" and work, unlike such spray heads, without the application of external pressure above and above Ambient pressure or by pressure caused by the process of Reducing the total content of the container is exercised, such as by squeezing the flexible walls a container like it for the dispensing of liquid Hypochlorite toilet cleaners, dishwashing liquids and the like liquid Products is well known.

Out practical reasons such as ease of construction and handling, the container preferably comprises no more than two chambers, each of which is a partial composition holds, whereby the compositions together form the final detergent composition according to the invention form. This implies that from the same reasons the detergent compositions according to the invention are preferred are formed from two sub-compositions. In addition can the container include a mixing chamber as indicated above.

The amounts of the sub-compositions forming the final composition need not all be the same as long as measures are taken that the concentration of each component in each of the sub-compositions is chosen so that when the respective amounts of the sub-compositions are mixed the correct concentration of each component in the Final composition is available. The volume of each compartment of the container is matched to the amount of sub-composition contained in the compartment which must add to the total amount of the final composition in the container. The total volume of liquid of the final composition to be obtained from the container is generally approximately equal to the total volume of the container, except for the volume of the mixing chamber, if any.

The Dimensions of the dispensing system, that is, the dispensing or outlet openings the chambers of the container, are such that a only dispensing the correct quantities of all sub-compositions that is required to properly complete the final composition to form in which each component is present in the desired concentration.

Even though it regarding the size and shape the container no theoretical limitation indicate the container for practical Purposes, such as ease of handling and dispensing, in general a total volume of 0.1 - 2 Liters, preferably at least 0.25 l, but preferably not more than 1.5 l. Also show for practical purposes two-chamber container preferably chambers with approximately the same volume, each hold approximately equal amounts of each of the two sub-compositions.

R ⁵ can represent more than one substituent in the aromatic ring. Representative examples of compounds according to the general structure (with an R ⁵ ) are given in the table below.

Especially useful are imine quaternary salts, in which R4 is an alkyl group, such as methyl, or substituted alkyl group and in which R6 is hydrogen or a C1-C5 alkyl or Phenyl group. Also very useful are those compounds in which R5 represents one or two methoxy groups, such as two methoxy groups in positions 6 and 7. Examples of preferred Imine quaternary salts are N-methyl-3,4-dihydroisoquinolinium salts and the corresponding quaternary salts, in which R6 is methyl or ethyl.

If a bleach activator compound is used, it can be a Component of the same sub-composition as the peroxide compound provided that the both together at a pH suitable for the partial composition is, have sufficient storage stability, with the pH requirements of the final composition become. Otherwise the activator and the peroxide compound kept separately in different sub-compositions. So point Sub-compositions composed of hydrogen peroxide and an imine quaternary salt contain, preferably a maximum pH of 6.5, more preferably at the most 6 on.

In order to achieve thorough mixing of the sub-compositions upon delivery of the sub-compositions, all should be thin before mixing, ie a viscosity of 20 mPas or less, preferably 10 mPas or less, more preferably at most 5 mPas (Haake ^™ R20 viscometer, 25 ° C, shear rate: 21 s ^–1 ). Although the viscosities of all of the sub-compositions do not necessarily have to be the same before mixing, they are preferably not far apart since this can affect the relative amounts of the sub-compositions that are dispensed in a dispensing operation and the mixing thereof. A difference in viscosity can be compensated for by adapting the delivery means, for example by correspondingly different dimensions of the delivery openings of the corresponding chambers.

During or the detergent composition thickens immediately after application to the surface to a sufficient extent so they're on the surface hang remains and is prevented from running off a non-horizontal surface, before proper cleaning is achieved. This thickening will by mixing the components of the multi-component thickening system brought about whose components over at least two sub-compositions are distributed. The viscosity of the final composition after delivery is at least 50 mPas, more preferably at least 100 mPa · s. on the other hand is the viscosity preferably not more than 1000 mPa · s (measurement conditions: see above).

So that they are for the Detergent compositions according to the invention are suitable, should preferably have at least one component in the same sub-composition how the peroxide bleaching compound are stable on storage. The overall thickening system should be sufficiently stable in the final composition to enable, that itself the composition thickens and remains on the surface long enough to exert their cleaning effect.

It are many thickening systems in thickened hypochlorite bleaching compositions been used. Such systems often consist of two or more different ones Detergent surfactants or from one or more such surfactants in combination with an electrolyte, such as an inorganic salt. Many thickening systems comprise as one of their components a tertiary amine oxide, an ethoxylated Fatty alcohol or other nonionic surfactant, and as others Component an anionic surfactant.

Examples for such Thickening systems are in EP-A-079 697, EP-A-110 544, EP-A-137 551, EP-A-145 084, EP-A-244 611, EP-A-635 568, WO 95/08611, DE-A-19621048 and in the literature cited in these patent applications.

Examples are polymers of acrylic acid, the for their thickening properties are known, like those that are sold under the registered trademark "Acusol".

Examples of different thickening systems, preferred ranges of the relative amounts of their components (in% of the total surfactant mixture) and their possible distribution over partial compositions are given below:

at In some multi-component thickening systems, the components can all be in of a partial composition if at least one of the components is in a concentration below the concentration, necessary to cause the system to thicken, and the rest of this component in a different sub-composition is present. Then the concentration when mixing the sub-compositions this component in the final composition to the extent that is required to cause thickening. Detergent surfactants often play an important role in thickening systems, as above cited.

Independently of they are also preferred because of their wetting properties on hard surfaces and added because of their cleaning properties. Accordingly, they are surfactants preferably present, even if a non-surfactant-based thickening system is used. If not for the thickening is required, the total content of surfactants preferably between 0.1 and 20%, more preferably between 0.5 and 10%, most preferably at most 7%. If they are part of the thickening system, the minimum is Total amount of surfactant at least 0.5%, preferably at least 1 %.
