Definitions

  • the present invention relates to self adhesive hard surface cleaning blocks, and their use.
  • Hard surface cleaning blocks such as lavatory blocks are known in the art and are typically configured to provide an automatic and sustained release of active ingredients to a liquid passing the block and/or the release of perfume to the air.
  • they may be suspended in a container under the rim of a lavatory bowl or urinal such that, during a flushing cycle, water from the cistern flows over the block thereby dissolving a portion of the block and releasing active ingredients of the block into the lavatory bowl. They may also be used inside a dish washing machine or even for the purpose of manual dishwashing.
  • Holders for solid detergent blocks are for instance disclosed in EP-B1-586 137 .
  • An alternative to the lavatory block is a liquid dispenser device, such as the device disclosed in GB2389123 .
  • Both the liquid and the solid rim device require a holder connecting the lavatory block to the toilet rim.
  • Present day consumers do not like the idea of having to touch and handle a device that has been in the toilet for weeks, when refilling or replacement is required. Due to environmental reasons, disposal of such devices is also not appreciated by the consumers.
  • One such alternative is a tablet for use in the water cistern.
  • this kind of device cannot be used in built-in water cisterns that are becoming more and more popular.
  • Another alternative is a pump device having a dispenser at the toilet rim and a separate bottle with cleaning liquid outside the toilet. This option has the disadvantage of a tube connecting the rim device to the bottle with cleaning liquid.
  • a hard surface cleaning block comprising an adhesive phase meets at least one of these objects.
  • the invention provides a self-adhesive hard surface cleaning block, comprising
  • the invention further provides methods for providing hygiene to a toilet and methods for washing dishes with the hard surface cleaning block of the invention as further explained herein below.
  • the hard surface cleaning block according to the invention comprises of an adhesive phase and a detergent phase.
  • the purpose of the adhesive phase is to apply the detergent phase to a hard surface.
  • the purpose of the detergent phase is to release detergent material and other components incorporated in the detergent phase to the hard surface for treatment thereof. This normally happens when the block comes in contact with water, e.g. by flushing of a toilet in application as a toilet block, or by wetting the block before use in dishwashing applications. The block is then partially dissolved upon each contact with water.
  • composition of the block is preferably selected in such a way that there is a balanced level of surfactant and structurant to give proper foam and strength to the block.
  • One of the aspects of the invention is to develop an adhesive system which can easily be washed away by gentle rubbing of the surface on which the block is applied.
  • the block is adhered sufficiently strong to take the pressure of passing water in a toilet, sink or shower, while on the other hand the adhesion is not so strong that It is difficult to remove the adhesive material from the surface after the product is used up.
  • the detergent phase may be any kind of detergent phase. It may for instance be a solid, a semi solid or a gel.
  • the detergent phase may be transparent, translucent, opaque, or not transparent at all.
  • the detergent phase may be directly attached to the adhesive phase or indirectly, e.g. in a cage or with a separation layer between the phases.
  • the detergent phase comprises surfactants. Suitable surfactants are described in " Surface Active Agents” Vol. 1, by Schwartz & Perry, Interscience 1949 , Vol. 2 by Schwartz, Perry & Berch, Interscience 1958 , in the current edition of " McCutcheon's Emulsifiers and Detergents” published by Manufacturing Confectioners Company or in " Tenside-Taschenbuch", H. Stache, 2nd Edn., Carl Hauser Verlag, 1981 .
  • the adhesive phase is suitable for attaching the detergent phase to the hard surface.
  • the self adhesive detergent blocks of the invention are challenged by the flow of water, whether the block is adhered to a sink, dishwashing machine, or toilet.
  • the force that water applies to a toilet block, with a frontal surface of 10cm 2 is 0.3 N at an average flush. Therefore, the force required to release the block from the surface is preferably more than said 0.3 N.
  • the adhesive phase comprises a hydrophobic adhesive material and optionally a hydrophilic adhesive material.
  • the hydrophobic adhesive material is required for the invention to obtain suitable resistance to water.
  • the composition may further comprise a hydrophilic adhesive material.
  • the hydrophobic adhesive material comprises at least one of a hydrophobic compound with an aggregate melting point of 30 to 60 °C, preferably 45 to 55 °C and a polymer.
  • the hydrophobic compound is present in the hydrophobic adhesive material in a concentration of 25-60%, preferably 35-55%, more preferably 40-50% by weight based the hydrophobic adhesive material.
  • the adhesive phase further comprises a polymer in a concentration of 5-75%, preferably 20-70%, more preferably 40-65%, most preferably 50-60% by weight based on the hydrophobic adhesive material.
  • the hydrophobic compound is selected from natural or mineral oils, petrolatum, thickened oils, partially hydrogenated oils or fats, silicon oils and derivatives, thickened non polar solvent or low HLB non ionic surfactant and combinations thereof.
  • Low HLB as defined herein means preferably less than 12, more preferably less than 10.
  • the polymer is selected from natural and synthetic cellulosic polymers, such as carboxymethyl cellulose, polyacrylates, polyvinyl pyrolidone, maleic/vinyl copolymers, silicon based polymers and mixtures thereof.
  • the polymers in the hydrophobic adhesive material are preferably water insoluble and preferably swell in contact with water.
  • the adhesive phase optionally comprises a hydrophilic adhesive material.
  • the hydrophilic adhesive material if present, is preferably positioned in such a way that it is connected to both the hard surface and the detergent phase or an intermediate phase between the detergent phase and the adhesive phase, while it is surrounded by the hydrophobic adhesive material on all other sides.
  • the hydrophilic adhesive material is postulated, without wishing to be bound by a theory, that it is possible to obtain said further improved adhesion by the combination of hydrophobic adhesive material surrounding hydrophilic adhesive material, because the hydrophobic adhesive material stops the penetration of water while the hydrophilic adhesion material further improves the adhesive strength to the block.
  • the hydrophilic adhesive phase is preferably selected from starch based adhesive materials, hydrophilic polymers, fatty acid salts and/or mixtures thereof.
  • a hydrophilic adhesive is a mixture comprising PVP polymer and sodium stearate.
  • the hydrophilic adhesive material is present in an amount of 0-60% by weight of the total adhesive phase.
  • the ratio of hydrophobic:hydrophilic adhesive material is between 10:1 and 1:10, more preferably, between 5:1 and 1:5, still more preferably 4:1 and 1:2, most preferably between 2:1 and 1:1.
  • Either one or both of the adhesive materials may further comprise a suitable rheology modifier.
  • the rheology modifier is present in a concentration of 0-10%.
  • Polymeric thickeners are an example of suitable rheology modifiers for fumed silica or silica oil; hydrogenated triglycerides or fatty acids are an example of suitable rheology modifiers for fatty acids and triglycerided; and an example of a suitable rheology modifier for anhydrous, hydrophobic oils is 12-Hydroxy stearic acid.
  • the hard surface cleaning block according to the invention may further comprise builders, dyes, perfume, hygiene agents, antioxidants, radical scavengers, chelating agents, hydrotropes, anticorrosion agents, opacifiers, brighteners, preservatives and/or abrasives.
  • Each of the optional components may be included in the detergent phase, in the adhesive phase or in both phases
  • an intermediate phase may for instance be present to prevent interaction between phases or to improve the adhesion between the phases.
  • the intermediate phase is preferably a water resistant film.
  • the intermeditate layer when present, acts as a protective layer that does not allow water to penetrate between the adhesive phase and the detergent phase, thus providing additional protection to the adhesive phase.
  • the intermediate phase may be a polymer film, a solid barrier, or any other known barrier layer. Suitable polymer films are described in co-pending applications WO-02/090475 or WO-03/046119 . Suitable non-polymer based barrier layers may be found in e.g. EP-B-1 491 622 , EP-B-1 522 575 or EP-B-1 705 241 .
  • the thickness of the intermediate layer is at least 50 microns, an preferably less than 500 microns. The most preferred range is 100-200 microns. If the thickness is less than about 50 microns, the strength of the coating is not sufficient to protect the glue. More than 500 micron is uselessly expensive.
  • the detergent phase may also be surrounded by a casing, to which the adhesive phase is attached.
  • a casing may be similar to the commonly used types in most housing cages for solid toilet blocks.
  • the shape of the hard surface cleaning block may affect the adhesive properties of the block. It is preferred to have hydrodynamic shapes of the block, which help in better control of the erosion properties of the block which in turn helps in better adhesion of the block to the surface. Thus, round, smooth shapes are preferred over square/rectangular blocks with sharp edges, due to superior hydrodynamic behaviour.
  • a normal size toilet block is between 30 and 50 grams, usually about 40 grams. This sort of block typically lasts for at least 100 flushes, preferably more than 200 flushes. The blocks preferably last for up to about 300 flushes.
  • the required amount of the adhesive phase is determined by the surface of the detergent block.
  • the amount of adhesive phase material is preferably at least 0.01 g/cm 2 , more preferably at least 0.05 g/cm 2 , still more preferably at least 0.1 g/cm 2 , but preferably not more than 1.5 g/cm 2 , more preferably not more than 0.3 g/cm 2 , still more preferably not more than 0.2 g/cm 2 .
  • the hard surface cleaning block may be used for cleaning hard surfaces of any kind.
  • the most suitable surfaces are those that are regularly contacted with water, such as toilet surfaces, kitchen sinks and showers.
  • the present invention provides a method for providing hygiene in a toilet comprising the step of applying the block according to the invention to the toilet surface.
  • the detergent phase is spent, the remains of the adhesive phase are preferably brushed or flushed away.
  • the present invention further provides a method for washing dishes comprising the steps of applying the block according to the invention to a kitchen sink and filling the sink with water. Thereby the water comes in contact with the block and releases part of the detergent phase to the water.
  • the present invention further provides a method for washing dishes, the method comprising the step of applying the block according to the invention to the inside of a dishwashing machine.
  • the adhesive layer of the present invention preferably adheres the detergent phase to a hard surface hard surface directly.
  • the detergent phase is held by a cage and the cage be adhered to the surface.

  • the adhesive phases of the example are made by the following process.
  • Petrolatum and Vaseline® are melted in a mixer by heating it at about 60°C (sunflower seed oil was suitable for processing as is). Polymers and other ingredients are added in the clear melt and mixed slowly to avoid any aeration. If aeration takes place during the mixing then it is necessary to apply vacuum to de-aerate the mix before cooling. The de-aerated mass can be poured in an application tank from where it is directly pumped on the surface of the product. Colour and fragrance components may be added to the adhesive phase to give better performance of the product.

  • melt cast process the ingredients are mixed and melted by heating at elevated temperature. Additional ingredients, such as colour and fragrance components may be added to the detergent phase in this stage to give better performance of the product.
  • the homogeneous mass is then poured in molds and cooled to room temperature to solidify. Once the block is solidified, the adhesive phase is applied to the block.
  • the amount of adhesive phase used is about 100 mg/cm2.
