- the compositions comprise said surfactant in an appropriate amount below 1% by weight of the total composition.
- the composition of the reference does not include amine oxide surfactants.
- the compositions of the reference comprise thickeners.
- WO-A-94 28108 concerns oven cleaning compositions and does not deal with acidic limescale removing compositions.
- the subject invention is directed to a limescale removing composition which can be delivered as a foam.
- the subject invention provides an aqueous liquid storage- stable limescale removing foamable composition
- aqueous liquid storage- stable limescale removing foamable composition comprising: a. a mixture of sulphamic acid and at least one organic carboxylic acid; b. a thickening agent; c. an amine oxide surfactant.
- the subject invention provides a method of removing limescale from a substrate using the composition as set out above. Disclosure of Invention
- the composition of the invention comprises a mixture of sulphamic acid and at least one organic carboxylic acid.
- the sulphamic acid and the at least one other acid are preferably mixed in synergistically effective limescale removing amounts.
- the organic carboxylic acid has a molecular weight of 60-250. More preferably, the carboxylic acid is lactic acid, citric acid, or another hydroxy acid where the hydroxy group is ⁇ to at least one of the acid moieties.
- the mixture of acids is present in the range 5-20 weight percent of the aqueous cleaning composition and more preferably 10-20 weight percent.
- the composition of the invention can be dispensed as a foam through a foam dispenser.
- the composition may tend to be difficult to dispense in this way if the composition in use has a final viscosity which is much above 300 cps. All viscosity measurements stated herein are taken using a Brookfield viscometer, at 20°C using #3 spindle at 30 rpm. Preferably, the final viscosity is in the range 200-300 cps.
- the maximum viscosity of the composition of the invention is limited by the need for the composition to be dispensable through a foam dispenser, one aspect of particular importance is storage stability.
- the composition of the subject invention relies on a complex blend of components and inevitably the composition will be placed into its final package some long time before it comes into use in the hands of the ultimate consumer. It is important that the viscosity of the composition is maintained within parameters during storage to allow delivery through the foam dispenser. Long term stability of the viscosity is mainly determined by the optimized level and type of thickening agents. Thickeners which can be effective in the composition of the subject invention can be selected from the group consisting of acrylic emulsion polymer thickeners, xanthan gums, rhamsan gums, welan gums and polyurethanes. The preferred thickener is xanthan gum with altered rheology.
- the thickener is present in an amount of 0.001-5 weight percent based on the weight of the cleaning composition.
- the storage stable composition of the subject invention will preferably be dispensable as a foam through a foam dispenser after storage at room temperature for 6 months, and more preferable after storage at room temperature for 1 year.
- the storage stable composition of the subject invention will not show phase separation or precipitation after said storage, the viscosity of the composition remaining constant during said storage.
- the foaminess index ⁇ is between 15-50 and more typically between 20-30.
- the amount of thickener is instrumental in allowing the composition to remain storage stable, it should also be noted that the presence of particular amounts of other components in the composition may effect viscosity.
- the amine oxide surfactant can be expected to have an effect on the viscosity of the composition.
- Another important feature of the limescale removing composition of the invention is that the composition is dispensable as a foam. Dispensing as a foam allows the composition to remain on the limescale stain for an effective time. The composition should be able to remain in contact with and be able to wet and penetrate the limescale stain for a sufficient time to have an effective descaling effect. Subsequently, the composition must be able to be washed away easily with water.
- foams can be loose airy type foams, while at the other extreme, foams can be tight mousse like type foams.
- the composition of the subject invention ideally produces a foam which is roughly halfway between a loose airy type foam and a tight mousse type foam in order to give maximum descaling and a good cling parameter. Cling is measured by spraying about lOg of product onto the underside of a preweighed suspended plate weighing about 200g. The plate is left to hang for 5 minutes and is then re-weighed. The cling is determined by the amount of product remaining on the plate after 5 minutes.
- the cling parameter of the composition of the subject invention is 50 - 70% of product remaining on the surface after 5 minutes.
- the nature and amount of the amine oxide surfactant present in the composition of the invention will generally determine the foam profile and cling parameter of the composition. Additionally, however, the cling parameter is dependent on the amount of thickener present in the composition.
- the amine oxide preferably has the formula RR' R"NO, where R is a substituted or unsubstituted alkyl or alkene group contaimng from about 8 to about 30, preferably from about 10 to about 20, more preferably about 10 to 16 carbon atoms.
- R is an unsubstituted alkyl group.
- Groups R' and R" are each substituted or unsubstituted alkyl or alkene groups containing from about 1 to about 18, preferably from about 1 to about 4, carbon atoms. More preferably, R' and R" are each methyl groups.
- the amine oxide detergent surfactant can be prepared by known and conventional methods.
- One such method involves the oxidation of tertiary amines in the manner set forth in U.S. Patent No. 3,223,647 and British Patent 437,566.
- amine oxides are prepared by the controlled oxidation of the corresponding tertiary amines.
- the surfactant will be lauryl dimethyl amine oxide.
- the amine oxide surfactant is present in the amount of 2.0-8.0% by weight of the total composition.
- composition can contain other optional components appropriate to limescale removing compositions including dyes and fragrances.
- the balance of the composition of the invention (to 100 weight percent) is deionized water.
- composition of the invention is dispensable through a conventional foam dispenser.
- composition ofExample 3 had a viscosity of 250 cps and on dispensing through a conventional foam dispenser produced a foam with a cling parameter of 50 - 70% over a 5 minute period.
- the composition was stable on storage at room temperature for one year.
- the composition of Example 3 was tested for effectiveness by the marble cube test as follows:
- the average % weight loss (for the 3 cubes) ranged from 35 - 40%.
- a commercially available maleic acid limescale removing composition was tested in the same way as above and the % weight loss ranged from 20 - 30%.
- the subject invention provides a limescale removing composition which may be produced using conventional manufacturing methods and packaging.
- the foamable limescale removing composition maintains its foaming and rheological properties after shelf storage at room temperature for 6 months, preferably one year. This shelf stability will allow a consumer to effectively utilize the descaling composition even though the composition may be placed into its final package a long time prior to its purchase and use.
