Description:
POLISH COMPOSITIONS AND THEIR USES The present invention relates to polish compositions.

In particular the present invention relates to furniture polishes.

Many items of furniture, especially wood products, are popular and are present in the majority of households.

Because of the nature and expense of furniture, and in particular wood furniture, furniture polishes are widely used to clean and polish the furniture to protect it and prolong the life of the article.

Preferable qualities of furniture polishes are that they should give a desired gloss or matt finish to the surface on which they are applied, that this should not give smear marks which are detrimental to the appearance of furniture and that they should remove dust and dirt from the surface without scratching or otherwise damaging the surface of the furniture. In addition, the polishes should be easy to use and not require excessive effort to polish the surface to give the desired shine.

Many polishes include relatively large quantities of waxes, such as beeswax and paraffin wax, which impart a shine to the surface of the furniture, but have the disadvantage that large quantities of said waxes may lead to increased smearing on the surface of the article, and also make polish difficult to use.

A need exists for a polish, especially for articles of furniture, and especially for wood surfaces which polish

provides excellent glossing and shine properties while at the same time providing a low level of smearing and ease of use properties. It would be advantageous to provide a polish which utilises limited or no wax, but effects good gloss and cleaning properties on a surface to be cleaned.

It has surprisingly been found that utilisation of one or more silicones in the absence of wax, or with low concentrations of wax, provides effective polish properties with minimised smearing and excellent cleaning and protection of surfaces polished.

It would be further advantageous to provide an effective polish comprising relatively low quantities of volatile organic compounds, such as solvents, but which retain excellent cleaning and protecting characteristics.

It is therefore an aim of preferred embodiments of the present invention to overcome at least one problem of the prior art, whether expressly disclosed herein or not.

According to a first aspect of the invention there is provided an aqueous polish composition comprising an organic solvent that is immiscible with water, at least 0.75% w/w of a silicone and 0-0. 3% w/w of a wax; wherein the composition is substantially free from silicon dioxide, metal oxides and olefin-containing polymeric compounds.

By"substantially free from"we mean that preferably none of these compounds are contained within the composition. However they could be present in very small amounts due to manufacturing processes, or impurities present in components as supplied. None of these compounds have been deliberately added.

Percentage values quoted above denote the total complement of such components which are present; there may be more than one. For example there could be more than one silicone present and the percentage values given herein represents the total complement of silicones.

The silicone may be a single type of silicone or it may be a mixture of two or more silicones. Preferably the total silicone content is a mixture of different silicones, for example a blend of silicones having viscosities from 350 to 30,000 centistokes (CST), for example silicone 350, silicone 10,000 and silicone 30,000.

The silicone (s) is/are preferably present in an amount of at least 1% w/w, more preferably at least 2% w/w, still more preferably at least 3% w/w and most preferably at least 4% w/w (total weight of silicone (s) /total weight of the composition).

The silicone (s) is/are preferably present in an amount of less than 20% w/w, more preferably less than 15% w/w, still more preferably less than 10% w/w and most

preferably less than 6% w/w (total weight of silicone (s) /total weight of the composition).

Suitably the, or at least one, silicone is a polydimethylsiloxane.

The, or at least one, silicone may comprise a cyclic silicone, such as dimethicone, for example.

The, or at least one, silicone may comprise a siloxane polymer of the formula wherein each group A independently represents an alkyl group having up to 6 carbon atoms, M represents an alkyl group having up to 6 carbon atoms and Q represents an alkyl group, wherein a proportion of the groups Q have more than 20 carbon atoms and the remainder have up to 6 carbon atoms, and wherein"x"is an integer selected to give a molecular weight of the polymer III in the range 3,000-30, 000.

Preferably the longer chain groups Q have 21-40 carbon atoms, more preferably 21-36 carbon atoms, and most preferably 24-32 carbon atoms.

Preferably a group A is a methyl group.

Preferably a group M is a methyl group.

Preferably the shorter chain alkyl groups Q are methyl groups.

Preferably all groups A, M and Q are methyl groups, other than the longer chain alkyl groups Q.

Preferably the molecular weight of the compound I is in the range 5,000-20, 000, especially 6,000-12, 000.

In one embodiment of the invention the compound of formula III is in accordance with the following definition: where Q'is a longer chain alkyl group as defined above, w is 5-95 mol% and x is 95-5 mol%. Preferably w is 50- 95 mol %, especially 70-91 mol %. Preferably x is 5-50 mol %, especially 9-30 mol %.

In preferred embodiments the polish composition comprises two or more silicones, and more preferably comprises both a polydimethylsiloxane and a cyclic silicone.

It has been surprisingly found that a blend of two or more silicones, with limited or no wax, enables the aqueous polish compositions to effect good glossing and cleaning properties whilst avoiding excessive smearing

of treated surfaces. It has also been surprisingly found that the use of silicones with low or no wax in aqueous polish compositions allow said compositions to be manufactured comprising relatively low levels of volatile solvents and other volatile compounds, and as such non-volatile solvents may replace volatile solvents without detrimental effect to the efficacy of the compositions.

In particularly preferable embodiments the polish composition comprises three or more different silicones, and most preferably comprises at least one cyclic silicone and at least one polydimethylsiloxane, in addition to at least one further silicone.

In particularly preferred compositions the aqueous polish composition is wax free.

If present, suitable waxes include hydrocarbon waxes and esters of fatty acids and alcohols.

Suitable hydrocarbon solvents include petroleum distillates, alkanes, including paraffinic solvents, and isoparaffinic solvents. Alkane solvents are preferred.

It has been found that hydrocarbon solvents, particularly alkanes, are particularly effective in polish compositions comprising silicone and no or low wax.

Preferably the aqueous polish composition comprises two or more organic solvents, more preferably two or more hydrocarbon solvents, and most preferably two or more alkane solvents. Suitably at least one organic solvent

is a non-volatile organic solvent. Preferably at least one solvent is a volatile solvent and at least one solvent is a non-volatile solvent.

Preferably the organic solvent (s) is/are present in an amount of at least 0. 5%, more preferably at least 2%, most preferably at least 5% w/w (total of the solvent (s) /total weight of the composition).

Preferably the organic solvent (s) is/are present in an amount of no more than 40%, more preferably no more than 30%, most preferably no more than 25% by weight of the total weight of the polish composition.

The polish compositions of the invention may optionally include one or more conventional additives known to be useful in polish compositions, including viscosity modification agents, fragrances (natural or synthetically produced), foaming agents, water softening agents, corrosion inhibitors (such as sodium benzonate, for example), preservatives (such as isothiazolinones, Proxel GXL or Mergal K7, for example) and colouring agents. Such optional constituents should be selected so to have little or no detrimental effect upon the polishing efficacy of the compositions, and possibly a beneficial effect. Generally the total weight of such additives may comprise up to 40% by weight of the

composition, but preferably less, for example up to 20%, more preferably up to 10%, and most preferably up to 5%.

The polish composition is preferably a liquid.

Preferably it is an emulsion.

In a preferred formulation according to the present invention, the aqueous polish composition is designed to be spray dispensed from a container. This may be a trigger spray or an aerosol can. For aerosol dispensing the polish composition may optionally include from 3-20% w/w of a propellant, preferably 4-10% w/w and more preferably 5-8% w/w, the propellant preferably being a volatile organic compound having a suitable vapour pressure, for example, propane, butane, and isobutane.

It will be appreciated, however, that any typical aerosol propellants, such as halogenated hydrocarbons, dimethyl ethers and compressed gases, for example C02, N2 and LPG (Liquid Petroleum Gas) may be used. It will be appreciated that one compound may function as the solvent and as the propellant. In such cases the definitions given above for the amount of a propellant which should be present are applicable.

According to a second aspect of the present invention there is provided an aqueous polish composition comprising an organic solvent, at least 0. 75% w/w of a silicone and not more than 0.3% w/w of a wax.

According to a third aspect of the present invention there is provided an aqueous polish composition comprising a silicone or wax, and wherein the

composition comprises less than 20% w/w of a volatile organic compound (VOC).

Any of the features of the first aspect may be applied to the second or third aspects.

According to a fourth aspect of the present invention, there is provided a dispensing package comprising a polish composition of the first, second or third aspect, the dispensing package having a spray nozzle.

Preferably the package is non-pressurised and has a trigger spray to emit the polish. Most preferably, however, the package is pressurised and includes a propellant.

According to a fifth aspect of the present invention, there is provided a method of polishing a surface, the method comprising the step of treating the surface with a polish composition according to the first, second or third aspect of the present invention or using a dispensing package of the fourth aspect of the present invention. The surface may be a metal, plastics, wooden or glass surface, for example. The surface is suitably a porous surface, especially a wooden surface.

In this specification, unless otherwise stated, percentages refer to the weight of a component, on total weight of the polish (including a solvent and, if present, a separate propellant).

According to a sixth aspect of the present invention there is provided a polishing wipe comprising a sheet

material impregnated with an aqueous polishing composition of the first, second or third aspect of the invention.

The sheet material may be any sheet material capable of carrying and delivering the aqueous polish composition, and may be porous, absorbent and/or fibrous in structure.

Preferably the sheet material is a fibrous sheet material.

The sheet material could in principle be woven, but is preferably non-woven. For example, the sheet material may include non-woven sheet materials such as melt blown, coform, air-laid, bonded-carded web materials, hydro-entangled materials and combinations thereof.

Preferably, the sheet material is a non-woven fibrous sheet material comprising synthetic and/or natural fibres. Most preferably, the non-woven fibrous sheet material comprises viscose and/or rayon fibres.

Typically, the sheet material (dry) has a weight of at least 20 grams per square metre (gm-2), preferably at least 30gm-2, and most preferably at least 40gm-2.

Typically the sheet material (dry) has a weight of up to 80gm-2, more preferably up to 70gm-2, and most preferably up to 60gm-2.

A particularly preferred sheet material has a weight of approximately 50gm-2.

Preferably, the wipe has a size in the range 10 to 40cm by 10 to 40cm, more preferably in the range 15 to 35cm x 15 to 35cm.

Preferably the loading of the liquid composition on the wipe is at least 30gm-2, and most preferably at least 50gm-2.

Preferably the loading of the liquid composition on the wipe is up to 150gm-2, and most preferably up to 100gm- 2.

Preferably, each individual wipe is loaded with at least 3. 5g of the composition.

Preferably, each individual wipe is loaded with up to 5.5g of the composition.

Most preferably each wipe is loaded with approximately 5g of the composition. Advantageously, it has been found that this level of loading provides a wipe of size and grammage outlined above with sufficient moisture so that it does not dry out but which is not too wet to cause smearing in use.

In a particularly preferred embodiment each individual wipe has a size of approximately 20 x 30cm using a sheet material having a weight (dry) of 50gm-2, and is loaded with about 5g of the composition.

According to a further aspect, the present invention provides a packaged product comprising a substantially airtight container having a resealable opening and containing a wipe of the sixth aspect.

The container could be a tub or a soft-pack in the form of a pouch (hereinafter a"wrap"). Preferably, the container includes a plurality of wipes which are arranged in a generally folded configuration in a stack so that each wipe can be removed from the container one at a time. Such folded configurations well known to those skilled in the art and include C-folded, Z-folded, quarter-folded configurations and the like. Each wipe may be interfolded with the wipe immediately above and below in the stack of wipes so that the action of withdrawing one wipe raises a part of the wipe underneath it, to assist its removal. Alternatively the wipes may rest on each other in a stack without being interleaved.

Alternatively, wipes could be wound as a roll and separated by perforated tear zones and the container could be a tub having an opening through which wipes are pulled.

According to a further aspect, the present invention provides the use of the wipe as defined hereinbefore for cleaning a surface, for example of furniture.

Preferably, the wipe is used to clean surfaces of glass, wood, plastics, metal and the like.

According to a still further aspect, the present invention provides a method of manufacturing a wipe as defined hereinbefore, the method comprising the steps of providing a sheet material as defined hereinbefore and as part of the manufacture of the wipe moistening the sheet material with an aqueous composition as defined hereinbefore.

Preferably, in the manufacturing method, a supply roll of sheet material is unwound to provide a continuously moving web of material. The web of material is saturated or otherwise impregnated with the liquid cleaning composition by any suitable means such as spraying, dipping, or the like as are well known to those skilled in the art. In a particular aspect, the web of material is passed over several perforated tubes which feed the solution into the material.

In another embodiment a roll or stack of wipes is put in the container dry, and the liquid cleaning composition is injected into the container, to impregnate the wipes.

In one embodiment the web of material is slit in the machine direction into multiple ribbons, each of which may be folded into the type of fold desired for the individual wipe. The web of material is slit using a cutter, as is well known to those skilled in the art.

In a related method a wide roll of material is cut into a number of shorter rolls. A plurality of such shorter rolls are unwound at the same time. If wished the longitudinal edges of the unrolling webs (the edges

parallel to the direction of unrolling) are folded over against the central region of the webs. The unrolling webs are brought together in face-to-face manner and then cut at intervals, to form stacks ready to be packaged. In principle impregnation could be at any stage but in a preferred embodiment it is the individual unrolling webs which are impregnated, for example by spraying or dipping.

A resulting stack of wipes may be placed in a container, such as a plastics wrap or a tub, to provide a package of wipes. The container provides a substantially hermetically sealed environment for the wipes to minimise the escape of the liquid composition, by evaporation or otherwise.

According to still a further aspect of the invention there is provided a polish composition comprising: at least 55% w/w of water 0.1-1% w/w of a preservative 0. 1-15% w/w of a surfactant 0.75-30% w/w of a silicone 0-0. 3% w/w of a wax 0. 5-40% w/w of an organic solvent 0-20% w/w of propellant 0-15% w/w of additional components Preferably the polish composition comprises: At least 55% w/w of water (b) 0.2-0. 8% w/w of a preservative

(c) 0. 1-5% w/w of a surfactant (d) 1-20% w/w of a silicone (e) 0-0. 05% w/w of a wax 5-20% w/w of an organic solvent 0-10% w/w of propellant (h) 0-10% w/w of additional components The invention will now be described with reference to the following examples, formulations A to E.

Experiment A Smearing Test A wipe was folded around a rubbing block. 0.5g of Formulation B or D were then impregnated onto the top edge of the wipe. The wipe on the rubbing block was then wiped down the centre of a wooden tile measuring 30cm x 30cm. A clean duster was then wrapped around the rubbing block and the portion of the wooden board to which the polish had been applied was buffed by rubbing up and down five times with a cloth. A panel of at least ten people was then asked to assess the degree of smearing. The results indicated that the level of

smearing on the wooden block was very low, and aesthetically acceptable to the panel.

Experiment B The smearing tests were repeated as above for Experiment A, but using the Formulations A and C which were contained in a pressurised aerosol can. In these cases, 0. 5g of Formulations A and C were sprayed onto the respective wooden surfaces, and wiped with clean wipes in the same manner as described above. It was found that the aqueous polish compositions of Formulations A and C had excellent non-smearing properties and combined good glossing properties.

These results show that the aqueous polish formulations of the first and second aspects of the invention give good resistance the problem of excessive smearing, whilst retaining good glossing and cleaning properties.

The use of polish compositions comprising one or more silicones and no or low wax levels enables the polish compositions to be manufactured with lower quantities of organic solvents and volatile organic compounds, whilst remaining effective at glossing, cleaning and avoiding smearing.
