Definitions
- the present invention relates to a liquid detergent or detergent composition.
- Acidic aqueous solutions are preferably used to dissolve limestone deposits, which are usually due to water hardness.
- aqueous solutions with ingredients are suitable which, in aqueous solution, result in a pH in the neutral or alkaline range.
- the object of the invention is to create a liquid cleaning or detergent composition which, despite the surfactant content, has a good cleaning action even against inorganic contaminants.
- this object is achieved by a liquid detergent or detergent additive, which in the rest state is present separately in at least two aqueous phases, with a content of at least one surfactant in a concentration of less than 10% by weight and a content of at least one electrolyte in a concentration of less than 15% by weight, with the proviso that the composition contains, if any, less than 10% by weight of organic solvent and less than 6% by weight of sodium hexametaphosphate.
- the surfactant (s) is (are) present in a concentration of 0.5 to 6% by weight.
- the electrolyte (s) is (are) present in a concentration of at least 0.5% by weight.
- An alternative of the invention is characterized in that the electrolyte comprises at least one acid and the surfactant comprises at least in part at least one surfactant which has a net positive charge at the pH of the composition.
- the concentration of acid is 0.5 to 15% by weight.
- the concentration of acid is 7 to 10% by weight.
- the pH of the composition is below 4.
- the acid (s) which are preferably provided for use in this alternative of the inventive composition is (are) selected from the group consisting of phosphoric acid, amidosulfonic acid and mixtures thereof.
- the preferred surfactant (s) is (are) selected from the group consisting of quaternary ammonium salts, amines, amine oxides, betaines, sulfobetaines and mixtures thereof.
- this preferably comprises at least one builder or a builder system, at least one alkaline or alkalizing compound or mixtures thereof.
- the builder (s) or the builder system or the alkaline (s) or alkalizing compound (s) is (are) preferably present in a concentration of 0.5 to 6% by weight.
- the surfactant at least partially comprises at least one cationic surfactant.
- the inventive composition has a content of at least one further compound which promotes phase separation.
- this may be a compound which promotes phase separation by salting out, an alkali metal, alkaline earth metal or ammonium salt of an inorganic acid, preferably sodium chloride, being particularly suitable here.
- the compound which promotes phase separation is one which comprises at least one hydrophobic part and at least one anionic group.
- This can preferably be an anionic surfactant, xylene or cumene sulfonic acid or the salts thereof or mixtures thereof.
- the inventive composition is characterized by a content of at least one fragrance and / or a dye.
- the invention relates to the use of a composition which, in the rest state, is present separately in at least two aqueous phases and contains at least one surfactant, as a cleaning or washing agent.
- One of the aforementioned inventive compositions is preferably used.
- a particularly preferred embodiment relates to the use of such a composition containing at least one acid for removing limestone deposits, the corresponding compositions mentioned above also preferably being used here.
- a further embodiment of the composition according to the invention relates to the use of at least one electrolyte in a liquid cleaning and detergent composition containing at least one surfactant to promote the separation of the composition into at least two aqueous phases to improve the cleaning or washing performance of the composition.
- the invention relates to the use of xylene or cumene sulfonic acid or salts thereof in a liquid cleaning and detergent composition containing at least one surfactant and at least one acid to promote the separation of the composition into at least two aqueous phases to improve the removal of Limestone deposits.
- a cleaning or washing agent in the form of a composition which is present in the resting state separately in at least two aqueous phases leads to an unexpected improvement in the cleaning action of such compositions, in particular the dual action against both organic and inorganic contaminants ensures. If such a composition is shaken or mixed before or during use, a dispersion results which enables homogeneous application to the surface or the substrate. In the idle state, this dispersion separates relatively quickly both on the surface or the substrate and in the storage container in order to form separate aqueous phases.
- this separation on the surface to be cleaned or on the substrate to be cleaned is at least one of the reasons for the determined superior cleaning effect, since at least the negative mutual influence of the compounds used for the different cleaning purposes is reduced, in particular the negative influence of the surfactant or surfactants on the cleaning effect of the aqueous solutions against inorganic contaminants.
- compositions with two or more aqueous phases have hitherto not been disclosed. Such compositions have previously been described for cosmetics and personal care products (e.g. shampoos).
- GB-A-1 247 189 discloses a liquid composition for use as a shampoo or the like, which contains a surfactant, a water-miscible organic solvent and an electrolyte, the relative proportions of the electrolyte and the organic solvent being such that that the composition separates into two aqueous phases.
- Such compositions form a temporary oil-in-water emulsion when shaken and separate again into two phases when left to stand.
- the compositions require a significant level of organic solvent and / or electrolyte.
- shampoo compositions are known from EP 0 116 422 A1 and 0 175 485 A2, which also separate into two aqueous phases when at rest.
- EP 0 116 422 A1 - in addition to surfactant - a content of at least 6% by weight sodium hexamaphosphate is mandatory.
- EP 0 175 485 A2 the minimum content of surfactant in the composition is 11% by weight.
- the intended purpose of phase separation is only achieved when using special complexing agents, such as organophosphonates, amino carboxylic acids, etc.
- acids that are preferred to remove the limestone deposits are not the only possible choice.
- Possible other acids include, for example, citric acid, maleic acid, succinic acid, glutaric acid, adipic acid, hydrochloric acid, etc.
- citric acid maleic acid
- succinic acid glutaric acid
- adipic acid glutaric acid
- hydrochloric acid etc.
- other compounds or mixtures which have a corresponding cleaning action against inorganic contaminants are of course also suitable for the present invention.
- cationic surfactants such as those mentioned above, can be used in the neutral or alkaline compositions according to the present invention.
- non-ionic surfactant can help in some cases to set an approximately equal volume of the two aqueous phases.
- nonionic surfactant used in all known nonionic surfactants. All known nonionic surfactants are therefore suitable, in particular fatty alcohol ethoxylates and alkylphenol ethoxylates.
- fragrances and dyes are essentially determined from an aesthetic point of view and the stability of these compounds in the compositions according to the invention and does not pose any particular difficulties for the person skilled in the art in this field.
- Electrolytes (acid (s), sodium chloride)
- compositions according to the invention were investigated on a test model.
- a single-phase composition was used which had essentially the same composition as the compositions according to Examples I, II and IV, although the sodium cumene sulfonate had been replaced by water.
- the 2-phase formulation previously homogenized by shaking was tested against the single-phase comparison formulation which was identical in acid and surfactant content.
- a further acidic cleaner composition according to the invention is shown in Table 3 below.
- alkylbenzenesulfonate was used as the anionic surfactant instead of a salt of cumene or xylene sulfonic acid.
- Carrying out the calcium dissolving power tests described for the preceding examples likewise gives superior performance over a corresponding single-phase formulation, but the effect is not as pronounced as when using sodium cumene sulfonate or sodium xylene sulfonate. Examples VII to XV
- compositions according to the invention were investigated on a test model.
- the experimental setup was as follows: The following ingredients were mixed in the order given and stirred for two hours:
- pigment / grease dirt This standard soiling (referred to as “pigment / grease dirt”) was applied using a suitable coating device in a coating thickness of 100 ⁇ m to enamel strips (10 ⁇ 40 cm). The strips were stored for at least three days at room temperature in order to ensure an even drying process to reach.
- the cleaning tests were carried out with an automatic wiping machine (Erichsen). 2 ml of the composition according to the invention were each applied to a damp sponge. The number of wiping cycles was 20.
