Definitions
- This invention relates to a liquid hard surface cleaning composition
- a liquid hard surface cleaning composition comprising activated citrus fibre and abrasive calcite particles.
- hard surfaces are table-tops, leather, ceramic tiles, dish surfaces and car-bodies.
- cleaning compositions are typically used to improve cleaning efficiency (e.g. reduce the time and/or effort required).
- Hard surface cleaning compositions typically comprise surfactants which may aid in stain and/or soil removal, such as fatty stains/soils.
- Surfactants typically lower the surface tension of a liquid, the interfacial tension between two liquids and/or that between a liquid and a solid.
- Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.
- surfactants may end up in large amounts in land and/or water ecosystems. This can be problematic as surfactants may themselves exert toxic effects on animal and plant life and/or may increase the diffusion of other environmental contaminants and increase the exposure of animal and plant life with the latter.
- WO 2012/040142 discloses liquid cleaning compositions to clean a variety of inanimate surfaces comprising bleached cleaning particles as abrasives having a degree of whiteness (L * ) of greater than 65, measured under D 65 illumination.
- US 3,956,158 discloses pourable liquids comprising a three-dimensional network of insoluble entangled filaments having a diameter of 0.1 to 100 ⁇ m and a length to diameter ratio of at least 60, and particulate solid dispersed in the medium and prevented from separating from the medium by the filament network.
- US 2007/019779 discloses the use of microfibrous cellulose as structuring system.
- Citrus fibres and their uses for structuring of foodstuffs and personal care compositions are described in US2004/0086626 , US2009/269376 and WO2012/019934 .
- calcite particles are relatively free to move around. Therefore the calcite particles can move around (e.g. rotate) under applied force. The result of this is that the force applied on the particles, for example as a result of the rubbing effort of a human, is not efficiently transferred to the hard surface (containing the soils/stains).
- the added activated citrus fibre it is believed to form a network in the liquid cleaning composition that reduces the free movement of the calcite particles and thus improves the abrasive force exerted by the particles and the stains/soils.
- the invention relates to a liquid hard surface cleaning composition
- a liquid hard surface cleaning composition comprising:
- the invention relates to the use of activated citrus fibre in a liquid hard surface cleaning composition comprising abrasive calcite particles and liquid solvent to improve the cleaning efficiency.
- the improved cleaning efficiently of calcite particles and activated citrus fibre may be used to reduce the amount of surfactant in a liquid hard surface cleaning compositions with little or no reduction in cleaning efficiency.
- the invention relates to the use of activated citrus fibre in a liquid hard surface cleaning composition comprising abrasive calcite particles and liquid solvent to replace part or all of the surfactant, with little or no effect on cleaning efficiency.
- liquid hard surface cleaning composition comprising only natural ingredients, such as water, calcite particles and activated citrus fibre has good cleaning efficiency.
- the invention relates to the use of activated citrus fibre in a liquid hard surface cleaning composition comprising abrasive calcite particles and liquid solvent to provide an efficient cleaning composition which essentially consists of natural ingredients.
- the invention further relates to a process to manufacture the liquid cleaning composition according to the invention, comprising the following steps:
- the composition according to the invention is applied to the hard surface to be cleaned.
- the composition on the hard surface is agitated by manual and/or suitable mechanical means.
- cleaning efficiency is further improved by agitation the composition on the surface by using a non-absorbent means, such as a brush or non-absorbent cloth.
- the invention further relates to a method for cleaning of a hard surface comprising the following steps:
- the terms "soil” and “stain” as used herein generally comprise all kinds of soils and stains generally encountered in the household, either of organic or inorganic origin, whether visible or invisible to the naked eye, including soiling solid debris and/or with bacteria or other pathogens.
- the term 'soil' includes stubborn soil, which means strongly adhering soils that are typically very difficult to remove, such as burnt-on and/or baked-on food residues.
- Weight percentage (wt. %) is based on the total weight of the composition unless otherwise stated. Throughout this specification, all stated viscosities are those measured at a shear rate of 20 s-1 and at a temperature of 25°C unless stated to be otherwise. This shear rate is the shear rate that is usually exerted on the liquid when poured from a bottle.
- the liquid detergent compositions according to the invention are shear-thinning liquids.
- hard surface any kind of surface typically found in and around home or office houses like kitchens, bathrooms, e. g. , floors, walls, tiles, windows, cupboards, sinks, showers, shower plastified curtains, wash basins, WCs, fixtures and fittings and the like made of different materials like ceramic, vinyl, no-wax vinyl, linoleum, melamine, glass, Inox, Formica, vitroceramic, any plastics, plastified wood, metal or any painted or varnished or sealed surface and the like.
- Home or office hard surfaces also include household appliances including, but not limited to refrigerators, freezers, washing machines, automatic dryers, ovens, microwave ovens, dishwashers and so on.
- Such hard surfaces may be found both in private households as well as in commercial, institutional and industrial environments.
- Home or office hard surfaces include dish surfaces. With dish surfaces is meant herein dishes, glasses, pots, pans, baking dishes and flatware made from ceramic, china, metal, glass, plastic (polyethylene, polypropylene, polystyrene, etc. ), wood, enamel, Inox, Teflon, or any other material commonly used in the making of articles used for eating and/or cooking.
- An improved cleaning efficiency indicates that the removal of soil and/or stains from a hard surface requires less time and/or effort (e.g. force exerted by the user). For example when less swiping actions are needed to remove a stain/soil from a hard surface using about the same force, the cleaning efficiency is improved. For example, in case the same number of swiping actions is required, but less force needs be applied, the cleaning efficiency is improved. Clearly, an improved cleaning may also be indicated by a similar effort to remove an increased amount of soil/stain. It will be appreciated that some stains/soils type are harder to remove than others, and that to compare cleaning efficiency preferably a comparison is made using the cleaning of the same type of stain/soil.
- the amount of calcite particles in the liquid hard surface cleaning composition according to the invention is from 2 to 65 wt. %, more preferably from 3 to 60 wt. %, even more preferably from 4 to 55 wt. %, still even more preferably from 5 to 50 wt. % and still even more preferably from 6 to 45 wt. %.
- the average particle size of the calcium particles is not excessively large or excessively small to provide good cleaning efficiency.
- a calcite particle population with an excessively large average particle size e. g. above 2000 micron ( ⁇ m)
- excessively large particles are easily detected visually or provide bad tactile experience while handling.
- a calcite population with an excessively small average particle size e.g. below 0.1 ⁇ m
- the average size of the calcite particles improves the cleaning efficiency of the liquid composition according to the invention.
- the average size of the calcite particles is from 0.1 to 500 ⁇ m, more preferably is from 0.5 to 200 ⁇ m, even more preferably is from 1 to 100 ⁇ m, still even more preferably is from 2 to 75 ⁇ m, still even more preferably is from 3 to 50 ⁇ m and still even more preferably is from 4 to 25 ⁇ m.
- Abrasive calcite particles according to the invention of suitable average size can be made from calcium carbonate according to techniques known in the art.
- said particles can be made from calcium carbonate by mechanical grinding followed by suitable size sorting methods such as sieving.
- abrasive calcite particles of a range of average particles sizes are commercially available.
- calcium particles with a mean particle size of 2.6, 5 or 35 ⁇ m are available for example under trade names Omyacarb 2 - AV, Omyacarb 5 - AV and Omyacarb 30 - AV respectively (Omya Greater South, Milano, Italy).
- the average particle size may be measured using techniques and equipment known in the art (e.g. using sieve analysis).
- a Malvern Mastersizer X (Malvern Instruments, Worcestershire, UK) is used to measure particle size, operated according to supplier instructions.
- the calcite particles have sharp edges and on average a particle has at least one sharp edge. More preferably, a particle on average has a multitude of sharp edges.
- a sharp edge is an edge having a tip radius below 20 pm, preferably below 8 pm, most preferably below 5 pm. The tip radius is defined by the diameter of an imaginary circle fitting the curvature of the edge extremity.
- Activated citrus fibre may suitably be made from powdered citrus fibre.
- Powdered citrus fibre can be made according to the following general process:
- Microscopy shows that powdered citrus fibre is a heterogeneous mixture of particles with various sizes and shapes.
- the majority of the material consists of aggregated lumps of cell walls and cell wall debris.
- These, so called, xylem vessels are water transport channels that are mainly located in the peel of citrus fruits.
- the xylem vessels consist of stacks of dead cells, joined together to form relatively long tubes, 200 to 300 micron long.
- the outsides of the tubes are reinforced by lignin, which is often laid down in rings or helices, preventing the tubes from collapse due to the capillary forces acting on the tube walls during water transport.
- a preferred type of powdered citrus fibre is Herbafoods' Herbacel AQ+ type N citrus fibre.
- This citrus fibre has a total (soluble and insoluble) fibre content of greater than 80% and soluble fibre content of greater than 20%. It is supplied as a fine dried powder with low colour and has a water binding capacity of about 20 kg water per kg of powder.
- Activated citrus fibre may suitably be made from the powdered citrus fibre by 'activating' the powdered citrus fibre (hydrated and opened up structurally) via a high shear dispersion at a low concentration in water to form a premix. Because the dispersed activated citrus fibre is biodegradable, it is advantageous to include a preservative into the premix.
- the shear should not be high enough to lead to defibrillation. If a high-pressure homogeniser is used it should be operated between 200 and 600 bar. The more shear that is applied the less dense the resulting particles. Whilst the morphology is changed by the high shear, process aggregate size appears not to be changed. The fibres break down and then fill the water phase. The shear also rubs loose the outer parts of the cell walls and these are able to form a matrix that structures the water outside of the volume of the original fibre.
- An activated citrus fibre structuring premix may alternatively be made by milling using a high shear mixer, such as a Silverson.
- the premix may be passed through several sequential high-shear stages in order to ensure full hydration and dispersal of the citrus fibre to form the activated citrus fibre dispersion.
- the premix may be left to hydrate further (age) after the high shear dispersal.
- the activated premix is preferably used fresh.
- High Pressure Homogenised premixes are preferred over milled premixes, as they are more weight effective to provide sufficient suspending duty to liquids. Increasing the homogenisation pressure gives further increased weight efficacy to the premix.
- a suitable operational pressure is about 500 barg.
- the level of activated citrus fibre in a premix preferably lies in the range 1 to 5 wt%, more preferably 1.5 to 2.5 wt%.
- the concentration of activated citrus fibre in the pre-mix depends on the ability of the equipment to deal with the higher viscosity due to higher concentrations.
- the amount of water in the premix is at least 20 times greater than the amount of citrus fibres, more preferably at least 25 times even as much as 50 times. It is advantageous that there is excess water in order to hydrate the activated citrus fibre fully.
- Preferred premixes have a measured yield stress of at least 70 Pa measured using an Anton Paar serrated cup and bob geometry at 25°C.
- Activated citrus fibre is compatible with enzymes used in laundry and household care detergent compositions.
- the amount of activated citrus fibre in the liquid cleaning composition according to the invention is 0.025 to 5 wt. %, preferably 0.05 to 5 wt. %, more preferably 0.1 to 4 wt. %, even more preferably 0.15 to 3 wt. % and still even more preferably from 0.2 to 2 wt. %.
- the cleaning composition used according to the invention may comprise surfactant.
- Said surfactant (detergent active) is generally chosen from anionic and nonionic detergent actives.
- the cleaning composition may further or alternatively comprise cationic, amphoteric and zwitterionic surfactants.
- the amount of surfactant is from 0.1 to 75 wt. %.
- liquid hard surface cleaning composition according to the invention comprises at most 50 wt. %, more preferably at most 20 wt. % even more preferably at most 10 wt. %, still even more preferably at most 5 wt. % and still even more preferably at most 1 wt. % of surfactant.
- Suitable synthetic (non-soap) anionic surfactants are water-soluble salts of organic sulphuric acid mono-esters and sulphonic acids which have in the molecular structure a branched or straight chain alkyl group containing from 6 to 22 carbon atoms in the alkyl part.
- anionic surfactants water soluble salts of:

- alkyl-aromatic sulphonates such as alkylbenzenesulphonates containing from 6 to 20 carbon atoms in the alkyl group in a straight or branched chain, particular examples of which are sodium salts of alkylbenzenesulphonates or of alkyl-toluene-, xylene-or phenolsulphonates, alkylnaphthalene-sulphon
- the amount present in the cleaning compositions of the invention will generally be at least 0.1 wt. %, preferably at least 0.5 wt. %, more preferably at least 1.0 wt. %, but not more than 20 wt. %, preferably at most 10 wt. % and more preferably not more than 5 wt. %.
- a suitable class of nonionic surfactants can be broadly described as compounds produced by the condensation of simple alkylene oxides, which are hydrophilic in nature, with an aliphatic or alkyl-aromatic hydrophobic compound having a reactive hydrogen atom.
- the length of the hydrophilic or polyoxyalkylene chain which is attached to any particular hydrophobic group can be readily adjusted to yield a compound having the desired balance between hydrophilic and hydrophobic elements. This enables the choice of nonionic surfactants with the right HLB.
- Particular examples include:
- nonionic surfactants are:

- viscosity of the composition according to the invention may be modified by adding a suitable viscosity enhancing or lowering agent as know in the art.
- the premix comprising activated citrus fibre may either be added to the other ingredients of the liquid hard surface composition as a post dosed ingredient, or alternatively the composition can be formed by starting with the premix and then adding the other ingredients to it. Some high shear is preferably applied to disperse the premix in the composition fully but the duty is not as demanding as for the premix preparation.
- Activated citrus fibre benefits from substantially air free processing as this improves the stability of the resulting liquid compositions, especially to bottom clear layer separation.

- the invention relates to a process to manufacture the liquid cleaning composition according to the invention, comprising the following steps:
- structured detergent compositions may be prepared starting with the activated fibre to which the other ingredients are added in their normal order of addition.
- this has the further advantage that dispersion of the activated fibre by high shear continues during the addition of the later ingredients rather than as a post shearing step, thereby reducing the batch time.
- Cleaning of a hard surface may be carried out by simply applying the liquid hard surface cleaning composition according to the invention on the surface and leaving it for a sufficient period of time.
- the composition is agitated.
- Said agitation improves cleaning efficiency by increasing the abrasive force of the abrasive calcite particles on the stains/soils.
- the agitation may be manual, such as by the act of rubbing and/or swiping.
- the agitation may also be carried out using suitable mechanical devices known in the art. It was observed that further improved cleaning results are obtained when the composition is agitated using non-absorbent means, such by using a brush or non-absorbent cloth.
- An example of an absorbent means is a sponge or paper towel.
- the invention relates to a method for the cleaning of a hard surface using the liquid hard surface cleaning composition according to the invention comprising the following steps:
- the liquid hard surface cleaning composition according to the invention can be concentrated liquid, which may be diluted with for example water before use or may be read-to-use liquids.
- the liquid compositions are pourable liquids.
- liquid hard surface cleaning composition comprising only natural and non-toxic ingredients, such as water, calcite particles and activated citrus fibre had good cleaning efficiency.
- the invention relates to the use of activated citrus fibre and abrasive calcite particles in a liquid hard surface cleaning composition to provide an efficient cleaning composition which essentially consists of natural ingredients.
- the liquid hard surface cleaning composition according to the invention may be packaged in any suitable form of container.
- the composition is packaged in a plastic bottle with a detachable closure /pouring spout.
- the bottle may be rigid or deformable.
- a deformable bottle allows the bottle to be squeezed to aid dispensing.
- If clear bottles are used they may be formed from PET. Polyethylene or clarified polypropylene may be used.
- the container is clear enough that the liquid, with any visual cues therein, is visible from the outside.
- the bottle may be provided with one or more labels, or with a shrink wrap sleeve which is desirably at least partially transparent, for example 50% of the area of the sleeve is transparent.
- the adhesive used for any transparent label should preferably not adversely affect the transparency.
- liquid cleaning composition according to the invention may be stored and dispensed by any suitable means, but containers which allow easy and efficient application are particularly preferred, such as pump dispensers, more preferably spray dispensers, which even more preferably are hand-driven.
- the composition according to the invention is packaged in a container comprising a spray dispenser for dispensing said composition in the form of a spray.
- the spray dispenser is preferably a trigger spray but may be any mechanical means for ejecting the liquid in a spray or aerosol form.
- the cleaning performance was assessed using a Pellicle Cleaning Ratio (PCR) on a WIRA brushing machine (a.k.a. Martindale brushing machine) (SDLATLAS, M235, Manchester UK), as set out below.
- PCR Pellicle Cleaning Ratio
- WIRA brushing machine a.k.a. Martindale brushing machine

- Stookey G.K., Burkhard. T. A., Schemehorn, B. R., In Vitro Removal of Stain with Dentifrices, J Dent Res 61 (11):1236-1239, 1982 .
- a stained film is slowly deposited on bovine enamel slabs over a period of time and subsequently removed using a mechanical brushing procedure.
- PCR is assessed by removal of stain after brushing and measuring the change in L * value using a Chromameter.
- the L * values represent a black-white scale and these are then used to calculate the PCR cleaning percentage.
- Bovine incisors were cut into square slabs, polished and mounted in acrylic plastic. The thus obtained enamel slabs were stained by a broth comprising Tea/Coffe/Mucin.
- the staining broth was prepared by mixing 40 g instant coffee (Supplier Nescafe), 40 g instant tea (Supplier PG Tips), 30 g mucin (from porcine stomach, type II), 0.063 g ferric chloride, with 1 litre Tryptone Soy Broth (30 g Trypton soy broth powder per litre).
- the slabs were threaded onto wires on a staining rig and incubated at a slanted angle and at a constant temperature of 50 degrees Celsius, while rotating at 2 rpm. In this way, the slab surface was alternatively immersed in the staining broth and air dried. The broth is changed daily and after five days the slabs are taken off and washed with distilled water until all the loose debris is removed.
- the slabs are then brushed with soft toothbrushes (Mentadent soft 0.20mm diameter bristles, flat trim) which have been soaked for 30 minutes to hydrate the bristles.
- the slabs are brushed thus with 10ml distilled water to remove loose stain.
- the slabs are air-dried and the L * values (L * stained) are measured with a Minolta CR321 chromameter set to L a b colour space.
- the enamel slabs are then ranked according to ascending L * baseline values to have an even representation of the stain range. Using a standard randomisation the slabs are then allocated to the different cleaning solutions.
- the WIRA machine has four brush heads and eight enamel tooth slabs are used per treatment group with two replicates per head.
- the WIRA machine is set to about 5 minutes of brushing at 160 cycles per minute (about 800 brush strokes) using a liquid cleaning solution to be tested.
- the enamel slabs are rinsed with water to remove the liquid cleaning solution and dried using a soft tissue, to prevent any variability in colour.
- the chromameter is used to re-measure the L * value (L * brushed), taking four measurements per slab.
- the enamel slabs are pumiced, using a cloth (ercu twill) and flour of pumice,on a Buehler Grinder Polisher to remove all traces of visible stain.
- the enamel slab is then rinsed with distilled water, dried and L* value (L* pumiced) measured and recorded.
- PCR 100 * L * Brushed ⁇ L * Stained / L * Pumiced ⁇ L * Stained
- the results are analysed using JMP software to assess the significance of the results obtained.
- a premix comprising 2 wt% of activated citrus fibre (ACF) was prepared using the materials given in Table 2, according to the following method.
- the demineralised water was stirred using an agitator stirrer with overhead drive operated at 160 rpm.
- the Proxel GXL preservative was added.
- Herbacel AQ plus N Citrus Fibre (ex: Herbafoods) was added gradually to ensure no clumping. Stirring was continued for a further 15 minutes to allow the fibres to swell sufficiently prior to the activation stage.
- the activation stage was carried out by high pressure homogenisation (HPH) at 500 barg.
- Liquid cleaning composition of Examples 1 to 3 and Comparatives 1 to 6 were prepared with a composition as set out in Table 1. Results PCR-value Average Standard deviation Example 1 73 8.4 Comparative 1 4.4 4.1 Comparative 2 45.0 5.2 Example 2 73.8 9.0 Example 3 66.6 8.7 Comparative 3 11.4 3.8 Comparative 4 10.8 3.5 Comparative 5 57.5 6.0 Comparative 6 28.9 8.7
- a greatly improved cleaning efficiency is also seen in a composition comprising other typical ingredients found in hard surface cleaning compositions, such as surfactant (Example 2, Example 3).
- surfactant Example 2, Example 3
- the cleaning efficiency of the Example 1 i.e. natural liquid cleaning composition
- the composition according to the invention allows an all-natural liquid hard surface cleaning composition with good cleaning efficiency.
- the composition according to the invention allows a reduction in surfactant content with little or no effect of cleaning efficiency.
