Abstract
A method of producing a shear-thinning hard surface cleansing formulation comprises admixing water, a hydrophobically modified polymer which is a polycarboxylic or polycarboxylate polymer containing hydrophobic moieties providing associative groups, and other components of the formulation. The hydrophobically modified acrylic polymer is added to the water prior to any other component of the formulation which causes the ionic strength to increase above 200 microsiemens. By adopting the method, a composition of relatively low viscosity is obtained which thickens over time, e.g. 24 hours. This has advantages for pumping the composition around the manufacturing and packaging plant since the product may be packaged at low viscosity but has the desired high viscosity properties when used by the consumer. It is particularly preferred that composition does not include more than 0.5% by weight of fragrance. Glass cleaning formulations and bleaching formulations incorporating the above mentioned polyiners and low levels of fragrance are also disclosed.
Description
CLEANING COMPOSITION
The present invention relates to shear-thinning, thickened, cleaning compositions and methods for producing such compositions.
There is a trend in the market place to thickened hard surface cleaners. In particular products with shear thinning characteristics are beneficial due to their easy dispensability (low viscosity at high shear) and slow drainage/low run off (high viscosity at low shear). Such products are produced by a mixing procedure in which a thickening polymer (for giving the shear thinning properties) is added at the end of the mixing procedure. The viscosity increases significantly on addition of the polymer.
Thus the viscosity only increases at the end of the mixing procedure and this ensures easiest stirring during the major part of the mixing.
Typically products are mixed in batches of several tonnes and then piped to a filling machine. Shear thinning only becomes significant at high shear (shear higher than 200 s'), i. e. when a product is squirted on use or on filling. If the product is piped from a holding tank to a filling machine via relatively large diameter pipes then it (i. e. the product) will be at low shear and hence high viscosity. If the product is piped by a relatively small diameter pipe then the shear is higher and viscosity is lower but resistance to flow is higher (Reynolds number change). In either case there is a significant pumping requirement.
It is an object of the present invention to obviate or mitigate the abovementioned disadvantages.
According to a first aspect of the present invention there is provided a method of producing a shear-thinning hard surface cleansing formulation comprising admixing water, a hydrophobically modified polymer which is a polycarboxylic or polycarboxylate polymer containing hydrophobic moieties providing associative groups, and other components of the formulation, wherein the hydrophobically modified acrylic polymer is added to the water prior to any other component of the formulation which causes the ionic strength to increase above 200 microsiemens.
Ionic strength may be measured using a JENWAY conductivity meter using a conductivity probe with 0. 5 square centimetre platinised platinum electrodes and calibrated using 0. 01 molar potassium chloride at 25 C. The measurement may be made by immersion of the electrode into a stirred sample at 25 C and waiting until a stable reading is recorded. Thus it is a relatively simple matter to test whether any particular component of the proposed formulation, when added to water, would increase the ionic strength to above 200 microsiemens.
We have found that before addition of any component which increases ionic strength to greater than 200 microsiemens inclusion of the hydrophobically modified polymer into the formulation produces a composition of relatively low viscosity which thickens over time, e. g. twenty four hours. Depending on its degree of hardness, the ionic strength of water is generally below 150 microsiemens. Examples of materials which might be included in the formulations of the invention and which would cause the ionic strength above 200 microsiemens are inorganic ionic substances (e. g. salts, sodium hydroxide etc.) and organic ionic materials such as anionic surface active agents. The"as-mixed"viscosity of the formulation may, for example, be 60 to 120cp. The viscosity increase may for example by from 20 to 150 (as measured by a Brookfield LVT viscometer with heliopath, spindle A, 12rpm (unless otherwise stated all viscosities referred to herein are measured by this method)) and may increase over 24 hours to a value in the range 90 to 160. Thus the formulation can be pumped around the manufacturing and packaging plant (and the product may easily be packaged at low viscosity) easily whilst also having the desired high viscosity properties when used by the consumer.
The hydrophobically modified polymer may for example be polymer with a molecular weight greater than 10, 000 (more preferably greater than 20, 000) and less than 2, 000, 000 (more preferably less than 1, 000, 000) with from 1% to 50% (preferably 1% to 15%) by weight of partially hydrophobic monomers that can act as associative groups. The polymer may be cross-linked but preferably by no more than 2% of monomer residues (more preferably 0 to 0. 5%) providing the cross-links.
The hydrophobically modified polymer may for example be a copolymer of an ethylenically unsaturated carboxylic acid monomer and an ethylenically unsaturated monomer having a hydrophobic group. Suitable polymers may comprise 10-97% by weight of the residues derived from the ethylenically unsaturated carboxylic acid, 1 % to 80% of monomer residues having the hydrophobic grouping, and optionally other co-monomers.
Examples of unsaturated carboxylic acid monomers include acrylic, methacrylic, itaconic, maleic, sorbic, crotonic, oleic and linoleic acid.
Examples of co-monomers with hydrophobic groups include compounds of formula : A-O-(CH2-CHR2-O) X-(CH2) y-Ri wherein : A is the acylic residue of an ethylenically unsaturated carboxylic acid, selected from acrylic, methacrylic, itaconic, maleic, sorbic, crotonic, oleic or linoleic acid, Rl is an alkyl, alkylphenyl or aralkyl residue having from 1-30 carbon atoms.
R2 is hydrogen methyl or ethyl
x is 0 to 50 and y is 0 to 30 with the sum of x and y being between 0 and 80
More preferred co-monomers with hydrophobic groups are the esters of cetylstearyl alcohol ethoxylated with 25 moles of ethylene oxide, particularly the acrylate esters thereof.
The polymer may have a degree of cross-linking. Cross-linking may be achieved by the presence, in the polymerisation reaction, of a di-or higher ester of an ethylenically unsaturated carboxylic acid and a diol or higher functionality polyol.
Suitable examples of polymers disclosed in EP-A-0 870 785, the disclosure of which is incorporated herein by reference.
Examples of suitable polymers are available under the names POLYGEL W30 (ex 3V UK Ltd), Rheovis CRX and Rheovis CR (ex Allied Colloids).
It is preferred that the hydrophobically modified polymer constitutes from 0. 05-4% by weight of the hard surface cleaning composition. More preferably the polymeric material constitutes from 0. 1-1. 5% and even more preferably from 0. 20. 75% of the composition.
Compositions in accordance with the invention may be produced by batch or continuous mixing.
Various types of hard surface cleansing compositions may be produced using the method of the present invention, e. g. glass, toilet, kitchen and bathroom and cleaners and thickened bleach compositions.
Depending on the type of composition, any or all of the following components may be included.
(i) Surface active agent (anionic, cationic, non-ionic, zwitterionic)
(ii) Bleaching agents, e. g. hypochlorite, peroxy compounds.
(iii) Solvent, e. g. isopropyl alcohol, DPM (Dipropropylene glycol mono
methyl ether).
(iv) pH modifying agent, e. g. caustic soda.
(v) Fragrance.
(vi) dye, e. g. brilliant blue.
(vii) Preservative, e. g. formalin.
(viii) Thickener, e. g. amine oxide.
(ix) Crystal growth inhibitor.
(x) Builders (e. g. carbonate/bicarbonate/citrate/phosphate) (xi) Sequestrants (e. g. EDTA, phosphonates)
It is preferred that the composition does not include more than 0. 5%, preferably not more than 0. 2%, by weight of the fragrance. Higher amounts may affect the viscosity increase.
A preferred embodiment of the method of the invention is in the production of glass cleaning compositions, particularly a window cleaning composition. Such compositions as produced in accordance with the method of the present invention may comprise :
Hydrophobically modified polymer 0. 10-2. 0 wt%
Water Miscible Solvent 2. 0-18. 0 wt%
Fragrance 0. 0 to 0. 06%
Formaldehyde 0-0. 10wt% Dyes As Required
Water To 100wt%
The glass cleaning composition is an important aspect of the invention in its own right and therefore according to a second aspect of the present invention there is provided a glass cleaning composition comprising water, a hydrophobically modified polymer which is a polycarboxylic or polycarboxylate polymer containing hydrophobic moieties providing associative groups, and at least one water miscible organic solvent, said formulation containing less than 0. 2% by weight of fragrance and preferably not containing surface active agent. The glass cleaning formulation of the second aspect of the invention may be as identified in the previous paragraph and may be produced by the method of the first aspect.
The water miscible solvent may for example be at least one of isopropyl alcohol and dipropylene glycol mono methyl ether (DPM). Preferably the composition contains 2. 0 to 8. 0% by weight of isopropyl alcohol and 2. 0 to 10. 0% by weight of DPM.
Preferably the glass cleaning formulation has a pH of at least 9, more preferably 10 or more, (e. g. provided by inclusion of sodium hydroxide).
The above glass cleaning compositions are particularly effective at cleaning glass even though they do not contain a surface active agent. Furthermore we have observed that the compositions are not only able to clean glass without the addition of a surfactant but do so without leaving any residual smears on the glass. We believe that the properties are due to the hydrophobically modified poly-acrylic polymer having a degree of surface active character.
A further preferred embodiment of the method of the invention is in the production of thickened bleach compositions. The bleach composition may comprise, in addition to the hydrophobically modified polymer and water, a hypochlorite bleach and a bleach stable surfactant system. We have found that such formulations (which provide a further third aspect of the invention in their own right), in addition to their ease of manufacture, also have excellent"clingability"characteristics. As such, the thickened bleach (e. g. in the form of a gel) allows for greater residence time on vertical surfaces for improved bacterial kill. This film forming property can also inhibit limescale deposits on surfaces due to its gel like nature. This allows for significantly greater contact time on vertical surfaces for improved bacterial kill.
The composition of the third aspect of the invention may be produced by the method of the first aspect.
The bleach composition may comprise :
Hydrophobically modified polymer 0. 10-5. 0 wt%
(preferably 0. 1-3%)
Hypochlorite bleach 3. 0-5. 0 wt%
(preferably 4. 0-5. 0%)
(expressed as available chlorine)
Sodium or Potassium Hydroxide 0. 1-5. 0 wt%
Bleach Stable Surfactant System 1. 0-l0. 0wt% Fragrance 0. 01 to 0. 5%
(preferably 0. 01 to 0. 1%) Water Balance
The above composition is particularly effective for use as a toilet cleaner.
It is preferred that the bleach formulation does not contain more than 0. 2% by weight of the fragrance as higher amounts may affect the viscosity increase.
The pH of the composition is preferably greater than 12, e. g. a pH of 13 is suitable.
The bleach stable surfactant system may comprise an amine oxide of the formula :
where Rl and R2 are the same or different C)-4 alky ! groups (preferably methyl) and R3 is a C822 alkyl group.
A further bleach stable surface active agent which may be used is an alkyl ether sulphate having an alkyl group of 8 to 22 carbon atoms and an average of 3-5 moles EO. A preferred surface active agent in this category is sodium lauryl ether sulphate with an average of 2 moles EO.
The surface active agent system preferably comprises, by weight of the thickened composition, 1-5% (more preferably 1. 54%) amine oxide and 1-5% (more preferably 1. 5-4%) of alkyl ether sulphate. This mixture of anionic and non-ionic surfactants helps to boost and maintain the viscosity of the formulation.
The formulation may also incorporate a water soluble acrylic acid homopolymer, e. g. in an amount 0. 1 to 5% by weight, preferably 0. 1 to 2% by weight.
The polymer serves to prevent/remove limescale. Suitable acrylic polymers are those having a pH in the range 6-10 and are available under the trade name Sokolan (ex
BASF), e. g. Sokolan PA30 CL.
The bleach composition may incorporate minor components, e. g. fragrances and dyes. It is however preferred that the amount of fragrance does not exceed 0. 2% by weight (preferably does not exceed 0. 1% by weight) since greater amounts may adversely affect the viscosity increase of the formulation. We prefer that the amount of fragrance be in the range 0. 01% to 0. 1% by weight.
In producing the bleach composition it is preferred that the surfactant is added after the polymer. It is also preferred that the sodium (or potassium) hydroxide is added to provide a pH greater than 7 after the hydrophobically modified acrylic polymer, but before surface active agent system since the surfactant may interfere with neutralisation of the bleach giving anomalous results. The bleach may be added after the surface active agent system).
The invention will be further illustrated by the following, non-limiting

The above formulations together with Windowlene spray cleaner (original variant) designated as 368 were tested for their efficiency in cleaning glass.
(Windowlene is a Registered Trade Mark.)
For the purposes of the test, the products were packaged and labelled only with the three figure identifying codes given above. Each formulation was used to clean one of a number of adjacent sections of window glass with the boundary of each section being clearly marked on the glass by marker pen. (The reverse side of the glass were cleaned prior to the test with a UK Brand Glass Cleaner).
10 panellists were asked separately visually to evaluate each section of the glass and to score the degree of cleaning and degree of smearing in scales of 0-10 as follows :
Cleaning
0 = No cleaning 10 = Total cleaning
Smearing 10 = No smearing
0 = Total smearing
The results were as follows :

It will be seen from the above table that the thickened formulation with
W30 polymer and no surfactant (i. e. SWC 358) gave improved cleaning vs formulations incorporating both Carbopol (with and without surfactant), the formulation based on WO-A-97143372 (with and without surfactant) and the brand formulation.
Formulation with W30 polymer and no surfactant (i. e. SWC 358) gave comparable cleaning to the same formulation incorporating surfactant (i. e. SWC 359).
Smearing
The thickened formulation with W30 (and no surfactant) (i. e. SWC 358) gave improved"none smearing"performance vs all other formulations testedincluding those prepared without surfactant.

Two methods (I and II) were used to produce the formulation 2 using the order of addition specified below. Formulation 1 was prepared using method I.
Method I Method II
1) Water Water
2) Polygel Polygel
3) Caustic Amine Oxide
4) Fragrance Ether Sulphate
5) Amine oxide Fragrance
6) Ether Sulphate Caustic
7) Hypochlorite Hypochlorite
Each of methods I and II was carried out to produce a 500ml sample in a 500ml glass beaker using a heidolph RZR1 strirrer on shaft one speed 0 which equates to 250-300 rpm. The strirrer blade was plastic and of U-shaped design.
In each method, the Polygel 30 W was added with mixing to the water and mixing was continued for 15 minutes prior to addition of the next component. After addition of caustic soda, mixing was continued for 15 minutes before addition of the next component.
For the purposes of nomenclature, formulation 1 as produced by, method I is designated as formulation 1 (I). On the same basis, the other formulations are designated 1 (II) and 2 (11).
The thickness of each formulation was measured 30 minutes after mixing and also after 18 hours using a flow cup method. The flow cup had an outlet orifice which was 3mm in diameter and 5mm deep. The time taken (in seconds) for a 100ml sample of the product to pass through the orifice was used as the measure of thickness.
The"clingability"of the formulations was also measured at the same time points by a method involving use of a white porcelain tile inclined at 45 C to the horizontal and having two marks spaced apart along the tile by 12cm. The time taken (in seconds) for 0. 1 g of the liquid applied to the upper line (by pipette) to travel to the lower line was taken to be a measure of"clingability".
The results are shown in the following table

The increases were greater for the formulations produced by method II (as compared method I). For the two formulations produced by method II, the increases were less at the highest fragrance levels.
This emphasised the requirement for a consistent method of manufacture with an appropriate order of material addition.
This is vital to the stability of the formulation.
