  • Surfactants employed in liquid abrasive cleaners have included, alkyl benzene sulphonates, alcohol sulphates, alcohol ethoxylates, alkyl amido ethoxylates, fatty acid soaps and secondary alkyl sulphonates. Combinations of these surfactants, together with electrolytes are generally used to form a suspending system as is well known in the art.

  • abrasive cleaners can be formulated with significant levels of a C 2 -C 6 alkanolamine and an electrolyte base other than alkanolamine.
  • the presence of alkanolamines is desirable as at elevated pH due to the base the alkanolamine can act as both a solvent and as a further base to assist in the removal of difficult soils.
  • the present invention provides a abrasive cleaner which effectively cleans and is stable on storage.
  • the present invention provides a non-liquid abrasive cleaning composition which comprises
  • e optionally, 0.1-20%wt of a solvent other than water or alkanolamine It is believed that, in the presence of water, i.e. during use, the combination of the base and the alkanolamine improves cleaning.
  • the invention also extends to a method of light duty cleaning (i.e. dishwashing) which comprises the step of treating the articles being cleaned with a composition as disclosed herein.
  • a method of light duty cleaning i.e. dishwashing
  • non-liquid abrasive relates to products in the form of a paste, gel or powder.
  • a particulate abrasive phase is an essential ingredient of compositions according to the present invention.
  • the particulate phase comprises a particulate abrasive which is insoluble in water.
  • the abrasive may be soluble and present in such excess to any water present in the composition that the solubility of the abrasive in the aqueous phase is exceeded and consequently solid abrasive exists in the composition.
  • Suitable abrasives can be selected from, particulate zeolites, calcites, dolomites, feldspar, silicas, silicates, other carbonates, aluminas, bicarbonates, borates, sulphates, and, polymeric materials such as polyethylene.
  • Preferred abrasives for use in general purpose compositions have a Moh hardness of 2-6 although higher hardness abrasives can be employed for specialist applications.
  • Preferred average (weight average) particle sizes for the abrasive fall in the range 0.5-400 microns, with values of around 10-200 microns being preferred. In this range an acceptable compromise between good cleaning behaviour and low substrate damage is achieved.
  • Preferred levels of abrasive range from 60-95wt% on product, preferably in the range 65-90wt%.
  • the physical form of the product will be influenced by the level of abrasive present.
  • compositions with higher levels of abrasive will be powders whereas those with lower levels will be pastes.
  • Exactly where a particular abrasive product changes from powder to paste with a particular abrasive present at decreasing levels is influenced by the other components present. From the preferred embodiments of the invention described below it can be seen that the compositions become a paste if the level of abrasive falls below 80-90%wt.
  • the physical stability of a paste may be improved by having a high level of abrasive present.
  • a high level of abrasive is greater than 80% by weight of the total composition.
  • the most preferred abrasives are calcium carbonate (as calcite) , mixtures of calcium and magnesium carbonates (as dolomite) , sodium hydrogen carbonate, potassium sulphate, zeolite, alumina, hydrated alumina, feldspar, talc and silica.
  • Calcite, feldspar and dolomite and mixtures thereof are particularly preferred due to their low cost, suitable hardness and colour.
  • Alkanolamines for use in the compositions of the present invention can be mono- or poly-functional as regards the amine and hydroxy moieties.
  • Preferred alkanolamines are generally of the formulation H 2 N-R ⁇ -OH where R ⁇ is a linear or branched alkyl chain having 2-6 carbons.
  • Preferred alkanolamines include:
  • 2-amino-2-methyl-l-propanol mono- di- and tri- ethanolamine, mono-, di- and tri -isopropanolamine, dimethyl-, diethyl or dibutyl ethanolamine, and mixtures thereof.
  • cyclic alkanolamines such as morpholine can also be employed.
  • alkanolamines include: 2-amino-2- methyl-1-propanol , mono-ethanolamine and di-ethanolamine. These materials are believed to give improved cleaning on tough or aged soils. Of these materials 2-amino-2-methyl-1- propanol (AMP) is particularly preferred.
  • AMP 2-amino-2-methyl-1- propanol
  • Typical levels of alkanolamine in the compositions of the invention range from l-10%wt. Higher levels are less desirable due to cost and as these may attack certain plastics materials. It is particularly preferred to use 2- amino-2-methyl-l-propanol at a level of 2-6%wt.
  • Suitable electrolyte bases include soluble carbonates and bicarbonates, although the use of hydroxides and other alkaline salts is not excluded. Alkali metal carbonates are particularly preferred, with potassium carbonate being the most preferred. Typical levels of electrolytes range from 0.5-5%wt, with 1- 2.5%wt being particularly preferred.
  • the level of the electrolyte should be such that in use the pH of the composition is raised above the pKa of the alkanolamine, and preferably to a pH at least one unit above the pKa of the alkanolamine. Whether the pH reaches the desired level can be tested by forming a 50%wt slurry of the composition with water and measuring the pH.
  • Electrolyte can serve a further function in compositions which contain relatively low levels of abrasive, in particular when the abrasive level is below 75% on product and/or where the product is in the form of a paste. It is believed that as a abrasive level in the compositions is lowered the compositions become progressively more unstable and the tendency for the compositions to separate into two phases increases. This can be overcome by the use of potassium carbonate as the electrolyte and the addition of water to the composition.
  • compositions which contain potassium carbonate and water it is preferable that the abrasive material is feldspar. It is believed that ion-exchange between the potassium carbonate and the other preferred abrasive materials (particularly dolomite) leads to a progressive buffering of the composition which lowers the pH and eventually reduces the effectiveness of the composition.
