Definitions

  • the present invention relates to aqueous compositions of acids or acidic salts and more particularly to novel compositions of these acids or acidic salts which include a thickening agent.
  • acidic salts refer to those compounds which in an aqueous solution liberate protons.
  • compositions for cleaning include toilet bowl cleaners, metal cleaners and brighteners, rust stain removers, denture cleansers, metal descalers, general hard surface cleaners and disinfectants.
  • compositions have sufficient viscosity so as to allow the composition to be effectively applied to surfaces, for example, by brushing, or to allow the composition to remain in contact with the surface for a sufficient time to act.
  • the latter function has particular relevance to the cleaning of angular surfaces such as those found in toilet bowls where prolonged contact between the composition and the bowl is required for effective cleaning.
  • compositions known in the art that have the requisite viscosity characteristics. Most of such compositions achieve their viscosity through the use of one or more of the following thickening agents:-
  • the cellulose derivatives and gums tend to hydrolyse on storage which results in a reduction in viscosity of the composition. They are also generally difficult to dissolve, in some cases intensive mixing being required in order to bring them into solution.
  • Acrylic acid polymers are generally only useful in solutions which have a pH near neutral and above. They also tend to hydrolyse on storage and to achieve viscosity, need to be neutralized with a fairly strong alkali.
  • Nonionic surfactants have the disadvantage that usually high levels of about 5-10 0 /o are required to achieve satisfactory viscosity, thus making them expensive to use.
  • poly(ethyleneoxide) water soluble resins also require generally high levels to achieve desirable composition viscosity and additionally, in some acid solutions show significant instability.
  • Sodium silicates are able to produce aqueous acid or acidic salt gel compositions.
  • the viscosity generally develops over a long period of time, for example, as much as twelve hours. In commercial manufacturing processes, this is often inconvenient. It is also to be noted that on storage, such gels tend to break down into small pieces which in many instances is undesirable.
  • compositions disclosed in the art which relate to an aqueous acid and/or acidic salt compositions include:-
  • the present inventor has recognized the difficulties of the prior art thickening agents for such aqueous acid or acidic salt compositions. Accordingly, the present invention seeks to provide alternative compositions to those of the prior art.
  • the present invention consists in a thickened aqueous composition
  • a thickening agent which is at least one of the compounds selected from the group consisting of compounds of the formula: in which R, R 3 is a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 1 is hydrogen, a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 2 is hydrogen, a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 4 is a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, Rs is a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, Rs is a substituted or unsubstituted al
  • the present invention consists in a method of forming a thickened aqueous solution, comprising dissolving in water (a) at least one compound selected from the group consisting of acids and acidic salts (b) a thickening agent which is at least one of the compounds selected from the group consisting of compounds of the formula: in which R, Rs is a substituted or an unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 1 is hydrogen, a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 2 is hydrogen, a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 4 is a substituted or unsubstituted alkyl, aryl, alkaryl, aralkyl or alkenyl group, R 5 is a substituted or unsubstituted alky
  • substantially water soluble means that a thickening agent and an acid or acidic salt selected in accordance with the invention, will together either be soluble in water at 25° C or at most will form a hazy soluble that does not separate into two phases during normal storage.
  • compositions of the present invention may be readily distinguished over those disclosed in the aforementioned patent application GB2071688 (Jeyes Limited) in that the compositions claimed therein are directed towards substantially acid insoluble amines or amine oxides, which require a substantially acid soluble cationic or nonionic surfactant to achieve thickening.
  • the present invention is limited to either amines or amine oxides which together with the selected acid or acidic salt are substantially water soluble, without a cationic or nonionic surfactant being required in the case of the amines to achieve solution and thickening, and in the case of the amine oxides, without the use of a cationic, nonionic or anionic surfactant, particulary an alkyl sulphate to achieve solution and thickening. It is also to be noted that in GB2071688 it is stated that neither of the amine, amine oxide, cationic surfactant or nonionic surfactant alone with an aqueous solution of an inorganic acid or acid salt will cause thickening.
  • Bolsing in the simplest embodiment of his invention disperses the selected amine in water, heats the dispersion to between 40°C and 100°C and then adds to it at least a neutralising amount of phosphoric acid, preheated to between 40°C and 120°C. Stirring is continued until the temperature falls to between 5°C and 25° C and the resultant composition is a paste consisting of the reaction products between phosphoric acid and selected amine.
  • Bolsing also discloses that other acids such as sulphuric, hydrochloric, tartaric, oxalic, hydrofluoric and nitric may be used as an additive to a base paste of his invention. He further discloses that other amines may also be used as additives.
  • the present invention may be distinguished over Bolsing when it is considered that the amines of the Bolsing invention must be derivatives of substituted or unsubstituted hydrocarbons having 8-24 carbon atoms, the selected amine must be reacted by heating with phosphoric acid to achieve viscosity and there is no hint or suggestion that acids other than phosphoric acid are operative. Additionally, with respect to acidic salts, it is noted that Bolsing refers to ammonium chloride as an auxilliary.
  • the present invention teaches that thickening can be achieved with a range of acids and acidic salts, no heating is required to obtain thickening and the present inventor believes that amines additional to those of Bolsing are operative.
  • either of the groups R or R s contains at least six carbon atoms. More preferably, either of the groups R or R 3 contains from 8 to 24 carbon atoms. Most preferably either of the groups R or R 3 contains from 8 to 24 carbon atoms in an unsubstituted alkyl or alkenyl group.
  • the groups R 1 and R 2 are independently a hydrogen atom or a lower unsubstituted alkyl group, where lower refers to groups containing 1 to 4 carbon atoms or a substituted alkyl group. More preferably the groups R i and R 2 are independently a hydrogen atom or a lower unsubstituted alkyl group. Most preferably, the groups R 1 and R 2 are independently a hydrogen atom or a methyl group.
  • the groups R 4 and Rs are independently a lower unsubstituted alkyl group, where lower refers to groups containing 1 to 4 carbon atoms or a substituted alkyl group. More preferably, the groups R 4 and Rs are independently a lower substituted or unsubstituted alkyl group. Most preferably the groups R 4 and Rs are independently a methyl, or hydroxyethyl, or hydroxy propyl group.
  • Preferred thickening agents of the present invention that are primary amines include Farmin O (Farmin is a registered trade mark of Kao Soap Co.) or Genamin OL-100D (Genamin is a registered trade mark of Hoechst), both of which are mainly oleylamine and Farmin T or Genamin TA100D, both of which are tallow fatty amine distilled.
  • These thickening agents are able to thicken organic acids including formic, acetic, DL lactic, adipic, glycollic, malonic, succinic, pentetic, ascorbic, chloroacetic, citric and propionic acids.
  • a strong ionic salt such as sodium chloride is required to achieve adequate composition viscosity in the preferred concentration range of thickening agent.
  • a strong ionic salt such as sodium chloride
  • increasing the concentration of thickening agent will increase viscosity in many cases.
  • the addition of extra thickening agent may increase the pH and thereby decrease the efficiency of a composition.
  • Preferred thickening agents of the present invention that are tertiary amines include Genamin S0302D (dimethyl soya bean oil fatty amine distilled) and Genamin TA302D (dimethyl tallow fatty amine distilled). These amines are able to thicken organic acids including citric acid, L tartaric acid, formic acid, DL malic acid, acetic acid, DL lactic acid, adipic acid, maleic acid, ethylenediaminetetraacetic acid, glycollic, malonic, succinic and propionic acid and inorganic acids including sulfamic acid, phosphoric acid, boric, hydrofluoric and sulphuric acid.

  • Preferred thickening agents of the present invention that are primary amines able to thicken acidic salts include farmin O, genamin OL-100D, Farmin T and Genamin TA-100D. These amines are able to thicken aqueous solutions of aluminium acetate.
  • the abovementioned preferred amines are in fact mixtures of a number of amines with one amine being predominant.
  • the present inventor believes that the predominant amine may function to solubilize the minor amines in compositions of the present invention.
  • Farmin O is predominantly oleylamine having an approximate alkyl content of 6% C 14 , 13% C 16 and 81% C 18
  • Genamin S0302D has an approximate average chain length distribution of 2% C 14 , 15% C 16 and 83% C 18

  • inorganic or organic acids such as monosodium citrate, sodium hydrogen sulphate, sodium dihydrogen orthophosphate, disodium ethylenediaminetetraacetate, aluminium acetate and potassium hydrogen tartrate, aluminium sulphate and aluminium potassium sulphate.
  • the concentration of acid or acidic salt may be varied over a wide range depending on the end use of the composition. In some cases, particularly where a strong acid such as hydrofluoric acid is used and a near neutral product is required, the concentration of acid or acidic salt may be as low as 0.01% w/w.
  • the concentration of acid or acidic salt may be in excess of 90%.
  • the concentration of acid or acidic salt will lie in the range of from 0.1 to 30% w/w.
  • the thickening agent will be present in a concentration in the composition of from 0.1 to 10% w/w.
  • concentration in the composition will lie in the range of from 0.4 to 5.0% w/w.
  • the concentration of the thickening agent may be varied appropriately. However, in some cases, it has been found that it is not possible to achieve sufficient composition viscosity for some applications. In such cases, the addition of a salt which has high ionic strength has been found to enhance the viscosity of these compositions. In most cases however, the concentration of thickening agent and high ionic strength salt will be optimized in order to produce a cost effective composition of the desired viscosity.
  • the ionic salts will be selected from alkali metal halides or sulphates and ammonium halides or sulphates. Suitable such salts include sodium chloride, sodium sulphate, potassium sulphate, potassium chloride, ammonium chloride and the like.
  • Arquad 16-50 which is hexadecyltri- methyl ammonium chloride or Arquad S-50 which is a mixture of octadecanyl and octadecadienyl trimethyl ammonium chloride.
  • Arquad is a trade mark of Armour Hess Chemicals.
  • compositions of the invention may be added to compositions of the invention depending on their end use.
  • germicides surfactants including anionic, nonionic, cationic and amphoteric, sequestering agents, corrosion inhibitors, perfumes and colouring agents may be added.
  • a principal advantage of the present invention is that an aqueous acid or acidic salt solution may be readily and easily thickened.
  • steps of obtaining such thickened compositions will be - (a) add an appropriate amount of acid or acidic salt to water and stir to dissolve, (b) add a thickening agent of the present invention to the solution and stir until dissolved and (c) added other ingredients if required, stirring to dissolve.
  • the thickening agent of the present invention is defined to be soluble in the selected acidic salt or acid solution, and as it will generally be easily wet, the step (b) above will be relatively rapid unlike many of the prior art thickening agents, which whilst they may be soluble are frequently difficult to wet.
  • thickening agents of the present invention are relatively inexpensive and in use produce smooth, homogeneous immediate thickening. Furthermore, thickened compositions are stable with respect to viscosity. For example, the present inventor has found that a citric acid composition thickened with Farmin O had no substantial change in viscosity when stored at room temperature for 12 months.
  • compositions of the invention have some surfactant and corrosion inhibition properties.
  • the former finding means that water immiscible substances such as fragrances may be directly solubilized in a composition of the invention without requiring the addition of emulsifiers or auxilliary solvents, and in compositions in which the surface active properties are required, potentially less or no additional surfactant would be required.
  • the present inventor has also found that if only sufficient of an acid or an acidic salt is present to just dissolve a thickening agent of the present invention, then a composition of near neutral pH may be obtained.
  • Farmin O may be used to thicken lactic acid at a pH of 6.5.
  • the advantage of this finding is that it may be used in aqueous liquid cleaners in general.
  • an acid or acidic salt which is usually considered to be water insoluble at room temperature may be brought into solution through the use of a thickening agent of the present invention, with thickening occurring.
  • the viscosity may be increased through the use of a strong ionic salt such as sodium chloride.
  • a strong ionic salt such as sodium chloride.
  • compositions of this type include ethylenediaminetetraacetic acid with Genamin S0302D as the thickening agent, potassium hydrogen tartrate with Genamin TA302D as thickening agent and pentetic acid with Farmin O as thickening agent.
  • examples 1 to 60 of the present invention, together with comparative examples 1A and 1B, in which the viscosity, in centipoise, of each was determined using a Brookfield RVT viscometer using a spindle and speed as appropriate at 25°C. Note that the thickening agent is asterixed in each case. All of these examples (except Nos. 27, 46 and 51) were produced by bringing the acid or acidic salt into solution, adding the thickening agent and mixing until dissolved, and then adding the other ingredients with mixing until dissolved.
  • Examples 27, 46 and 51 were prepared by dispersing the acid or acid salt in water, adding the thickening agent and mixing until solution occurred, followed by sodium chloride (if required) until a satisfactory viscosity was achieved.
  • Example 1 when compared with the viscosity of water (1A) and 5% w/w citric acid (1 B), is substantially greater. A comparison with an aqueous solution of the thickening agent in this case was not possible as the thickening agent is water insoluble.
  • the examples 1 to 60 disclosed herein may be used for example as toilet bowl cleaners, metal cleaners and brighteners and the like as well as applications such as gel batteries
