FIELD: personal use articles.

SUBSTANCE: invention relates to methods of hygiene in toilet, for washing dishes in the sink and dishwasher.

EFFECT: offer of a cleaning unit which can be easily located on a solid surface, and which is washed away with many washings, and leaves no residue that can not be easily removed, such as with toilet brush.

 

The technical field to which the invention relates.

The present invention relates to adhesive on a hard surface cleaning units and their use.

Prior art

Known cleaning blocks for hard surfaces such as toilet blocks, and typically formed to provide automatic and constant release of the active ingredients in the fluid passing through the block and/or selection of odorants in the air. For example, they can be suspended in the container below the top edge of the toilet or urinal so that when the flushing water from the tank was leaking at the block, thereby dissolving a portion of the block and releasing the active ingredients block the toilet. They can also be used in the dishwasher or even for the purpose of hand washing.

The prior art discloses various ways of using the blocks in the toilet. Holders of blocks of solid detergent are disclosed, for example, in EP-B1-586137. Alternative blocks for the toilet is a feeding device for liquid, such as the device disclosed in GB 2389123.

For solid and liquid element at the upper edge of the holder is required that connects the toilet block and toilet seat. Today's consumers don't like the idea touch and handled the device, which was in the toilet of the week in the red is the necessity of re-filling or replacement. From an environmental point of view, the removal of such devices is low valued consumers.

Attempts were made to solve the problem in different ways. One such alternative is the tablet for use in the water tank. However, the device of this kind cannot be used in embedded water tanks, which are becoming more and more popular. Another alternative is the device with the pump and dispenser for toilet seat and a separate container of cleaning fluid out of the toilet. The disadvantage of this option is the tube that connects the device to the upper edge of the container with cleaning fluid.

Another alternative adhesive paste which can be applied to the surface of the toilet, for example, from a tube, is disclosed in EP-A1-1086199. However, the concept of a paste, applied to the surface of the toilet requires that the consumer did some manipulations inside of the toilet, such as squeezing a tube and fixing the position of the paste. Additionally, the consumer does not like streaks or drops of paste.

Remains popular unit with detergent, which can be easily deposited on a solid surface.

The aim of the present invention is to provide a unit with detergent, which can be easily deposited on a solid, even wet, the surface is.

An additional objective of the present invention is to provide a unit with detergent that rinses off with numerous washouts and leaves no residue that can not be easily removed, for example, a toilet brush.

An additional objective of the present invention is the possibility of any suitable form block detergent.

Unexpectedly, it was found that the cleaning unit for hard surfaces containing the adhesion phase, corresponds to at least one of these purposes.

A brief statement of the substance of the invention.

Accordingly, the invention provides a cleaning unit for hard surfaces containing

- phase detergent

- the adhesion phase,

in which the adhesion phase contains a hydrophobic adhesive material, including:

- 25-60%of at least one hydrophobic compound with a total melting temperature of 30-60°C.; and

- 5-75% of the polymer.

Additionally, the invention provides methods for hygiene toilet and washing dishes cleaning unit for solid surfaces of the invention are explained in the description below.

These and other aspects, features and advantages will become more apparent to experts in the art upon reading the following detailed description and the accompanying formula image is the shadow. To avoid uncertainty all the characteristics of one aspect of the present invention can be used in another aspect of the invention. It is noted that the following examples aim to illustrate the invention and are not intended to limit themselves to these examples. Similarly, all percentages are by weight, unless otherwise specified. It should be understood that the numerical intervals, expressed in the form "from x to y are x and y. It should be understood that when the outlines for the individual characteristics of preferred intervals in the form "from x to y", all the intervals are also included different endpoints.

A detailed description of the invention

A cleaning unit for hard surfaces in accordance with the invention includes adhesive phase and the phase of the detergent.

The purpose of the adhesion phase consists of applying a phase detergent on a hard surface.

The purpose of phase detergent is in the selection of detergent and other ingredients included in the phase detergent on a hard surface for processing. Normally this happens when the unit comes in contact with water, for example, when flushing the toilet when using as a free block, or if the humidification unit before use when washing dishes. Then the block is partially dissolved after each contact with the ode.

The unit preferably selected to balance the ratio between detergent and structuring agent to obtain the corresponding foam and strength of the block.

One aspect of the invention is to develop adhesive system that can be easily washed off easy wiping surface, which is applied to the unit. Thus, on the one hand it is preferable that the block was attached firmly enough to overcome the pressure of the flowing water in the toilet, the sink or the shower, on the other hand, the adhesion is not strong enough to impede the removal of the adhesive material from the surface after consumption of the product.

Phase detergent

Phase detergent may be a phase of any detergent. It can be, for example, solid, semi-solid or gel. Phase detergent may be transparent, translucent, cloudy or opaque. Phase detergent can be directly attached to the adhesive phase or not directly, for example, in a frame or with a separating layer between the phases.

Phase detergent includes a surfactant. Suitable surfactants are described in "Surface Active Agents" Vol.1, by Schwartz S Perry, Interscience 1949, Vol.2 by Schwartz, Perry's Berch, Interscience 1958, in the current edition of "McCutcheon''s Emulsifiers and Detergents"published by Manufacturing Confectiners Company or in "Tenside-Taschenbuch", H Stache, 2nd Edn. Carl Hauser Verlag, 1981.

The adhesion phase

The adhesion phase preferably is suitable for attaching phase detergent to a solid surface.

Usually self-adhesive cleaning the blocks of the invention operates the water flow if the unit is attached to the sink, dishwasher or toilet. The impact of water on the free block with the front surface 10 cm2is 0.3 nm in average flow. Therefore, the force required to remove these blocks from the surface, preferably greater than 0.3 nm.

The adhesion phase comprises a hydrophobic adhesive material and optionally a hydrophilic adhesive material. Hydrophobic adhesive material in the invention is required to obtain an appropriate resistance. To obtain more durable joining the composition may further include a hydrophilic adhesive material.

Hydrophobic adhesive material includes at least one hydrophobic compound with a combined melting point of 30-60°C., preferably 45-55°C., and the polymer. The hydrophobic compound is present in the hydrophobic adhesive material with the content of 25-60%, preferably 35-55%, more preferably 40-50 wt.% in relation to the hydrophobic adhesive material. The adhesion phase additionally contains a polymer with a content of 5-75%, preferred is entrusted 20-70%, more preferably 40-65%, most preferably 50-60 wt.% in relation to the hydrophobic adhesive material.

The hydrophobic compound is preferably selected from natural or mineral oil, paraffin oil, gelled oil, partially hydrogenated oil or grease, silicone oil and derivatives, thickened non-polar solvent or non-ionic surface-active substances with a low HLB and combinations thereof. Low HLB, as defined in the description, means, and preferably less than 12, more preferably less than 10.

The polymer is preferably selected from natural and synthetic polymers cellulose, such as carboxymethylcellulose, polyacrylates, polyvinylpyrrolidone, maleic/vinyl copolymers, polymers, silicone-based and mixtures thereof.

The hydrophobic polymers in the adhesive material is preferably insoluble in water and preferably swell upon contact with water.

The adhesion phase optionally contains hydrophilic adhesive material. To prevent rapid dissolution of hydrophilic adhesive phase upon contact with water, the hydrophilic adhesive material, if present, is preferably placed so that it was connected with a solid surface and with the phase of the detergent or an intermediate phase between the phase of the washing means and the adhesion phase, he is surrounded on all sides hydrophobic adhesive material. Even so, one would expect that the hydrophilic adhesive material will quickly dissolve water, postulated, not wishing to be bound by theory, that you may receive specified additional superior adhesion combining hydrophobic adhesive material surrounding the hydrophilic adhesive material, since the hydrophobic adhesive material stops the penetration of water, while the hydrophilic material further improves the adhesion strength of the block.

Hydrophilic adhesive phase is preferably selected from adhesive materials based on starch, hydrophilic polymers, salts of fatty acids and/or mixtures thereof. One example of such a hydrophilic adhesive is a mixture containing the PVP polymer and sodium stearate.

Hydrophilic adhesive material is contained in an amount of 0-60 wt.% in relation to the total adhesion phase. Preferably the ratio of the hydrophobic: hydrophilic adhesive material is between 10:1 and 1:10, more preferably between 5:1 and 1:5, more preferably 4:1 and 1:2, most preferably between 2:1 and 1:1.

One or both of the adhesion material can optionally contain suitable rheological modifier. Preferably the concentration of the rheological modificat the RA is 0-10%. Polymeric thickeners are suitable example of rheological modifiers for pyrogenic silicon dioxide or silica oil; hydrogenated triglycerides or fatty acids are a good example of rheological modifiers for fatty acids and triglycerides; and an example of a suitable rheological modifier for anhydrous, hydrophobic oils is a 12-hydroxystearate acid.

Optional additional components

A cleaning unit for hard surfaces in accordance with the invention may further comprise washing agents, dyes, perfumes, hygiene additives, antioxidants, acceptors radicals, chelating agents, hydrotropes, anti-corrosion agents, mufflers, bishopshostel, preservatives and/or abrasives.

Each of the additional components, if present, may be included in the phase detergent, adhesive phase or in both phases.

Intermediate phase

For some purposes it may be useful to divide the adhesive phase and the phase of the detergent intermediate phase. This intermediate phase may be present, for example, to prevent interaction between phases or improve the adhesion between the phases. The intermediate phase is preferably water-resistant film. The intermediate layer, when present, acts to the protective layer, which does not allow water to penetrate between the adhesive phase and the phase of detergent, thus providing additional protection of the adhesion phase.

It was found that the presence of water-resistant film between phase detergent and adhesive phase additionally improves the adhesion of the unit to a solid surface within the desired number of swabs and/or Laundry rinsing uses.

The intermediate phase may be a polymer film, a solid barrier or any other known barrier layer. Suitable polymer films described in the applications WO-02/090475 or WO-03/046119. Suitable barrier layers on polimernoi basis can be found for example in EP-B-1491622, ER-IN-1522575 or ER-IN-1705241. The thickness of the intermediate layer is at least 50 microns, preferably less than 500 microns. The most preferred range is 100-200 microns. If the thickness is less than about 50 microns, insufficient strength of the coating to protect the adhesive. More than 500 microns useless expensive.

Alternative phase detergent can also be surrounded by a casing, which caused the adhesion phase. This casing may be similar to the commonly used types of most frames casing for solid toilet blocks.

The block size and shape

Form a cleaning unit for solid surfaces can affect its adhesive is tion block. Preferred hydrodynamic shape of the block, which help to control erosion of the block, which in turn improves the adhesion of the block to the surface. Thus, a rounded, smooth shape preferred square/rectangular blocks with sharp edges, thanks to the best hydrodynamic behavior.

The service life of the unit is directly connected with the recipe and block size. The normal size of the free block is 30-50 grams, usually about 40 grams. This kind of unit is usually at least 100 swabs, preferably more than 200 swabs. Preferably the blocks are up to 300 washes.

The required amount of adhesive phase is defined by a surface of the block detergent. To produce a suitable layer of adhesive phase, the amount of adhesive material phase is preferably at least 0.01 g/cm2more preferably at least 0.05 g/cm2even more preferably, at least 0.1 g/cm2but preferably not more than 1.5 g/cm2more preferably not more than 0.3 g/cm2even more preferably not more than 0.2 g/cm2.

Method of use

A cleaning unit for solid surfaces can be used for cleaning hard surfaces of any kind. The most suitable surfaces are those that contact the water, such as the surface of the toilet, kitchen sink and shower.

Thus, the present invention provides a method of ensuring the hygiene of the toilet, including the state of the application unit in accordance with the invention on the surface of the toilet. When the phase of the detergent used, the remainder of the adhesive phase is preferably removed by brushing or washed off.

The present invention additionally provides a method of washing dishes comprising stage drawing unit in accordance with the invention on the kitchen sink and fill it with water. Water is thus in contact with the block and extracts the part of the phase detergent into the water.

The present invention additionally provides a method of washing dishes comprising the stage of application of the block inside the dishwasher.

The adhesive layer of the present invention preferably retains the phase of the detergent directly onto a solid surface. However, from the scope of the claims of the invention does not exclude the retention phase detergent frame and attach the frame to the surface.

Examples:

The invention is further illustrated by the following non-limiting examples.

Phase detergent of example are prepared by the following method.

Block detergent can be performed by extrusion or molding the melt, depending on the dependency type. During extrusion of the ingredients are mixed and then extruded in the form of a bar. These bars are then cut into blocks of the desired size, and is applied to the adhesion phase. When molding the melt components are mixed and melted by heating to elevated temperature. Additional ingredients, such as dyes and fragrances that can beat added to the phase detergent at this stage to impart improved characteristics to the product. Then the homogeneous mass is poured into molds and cooling gap is up to room temperature for hardening. Once the block has hardened, the adhesive phase is applied to the unit. The number adhesional phase is about 100 mg/cm2.

It was found that when applied to the free surface of any combination of the adhesion phase (100 mg/cm2from tables 1 and phase detergent (40 grams of table 1), it remains firmly attached to the toilet at least at 100 swabs.

After spending unit during the dissolution process, a thin layer of adhesive phase light is removed by wiping the surface using the toilet brush. There is no residue on the surface after cleaning.

Example 2

Example 2 use phase detergent and adhesive phase of tables 1 and 2, but now separated from each other by an intermediate layer.

The intermediate layer in this example consists of a UV-cured material on the basis of epoxyacrylate, as disclosed in WO 03/046119, with a layer thickness of about 100 microns.

Put about 100 mg/cm2the adhesion phase.

It was found that when applied to the surface of the toilet any combination of the adhesion phase (table 1), an intermediate phase and a detergent (from table 2), it remains firmly attached to the toilet, at least at 200 swabs.

After spending unit during the dissolution process, a thin layer of adhesive phase is removed light FR is rcoi surface, using the toilet brush. There is no residue on the surface after cleaning.
