Definitions

  • the present invention relates to liquid dishwashing compositions and more particularly to such compositions which contain an anionic tenside, a combination of specific amphoteric surface active compounds and an alkyl polyglycoside.
  • liquid dishwashing compositions are primarily intended for hand dishwashing and are as a rule aqueous solutions containing anionic tensides, such as alkyl sulfonates and alkyl ether sulfates, as essential component. These dishwashing agents are entirely satisfactory with regard to cleaning effect, foam forming effect and foam stability. However, the dishwashing compositions based on this type of anionic surface active agents are not satisfactory with regard to mildness to skin, since they have a certain irritating and allergy causing effect.
  • nonionic alkyl polyglycosides have become of commercial interest for use in dishwashing formulations and other cleaning formulations
  • These non-ionic surface active compounds which are products based on natural raw materials, are advantageous for use in dishwashing and other cleaning compositions in that they are mild to the skin, have high biodegradability and good compatibility with other types of surfactants.
  • Alkyl polyglycosides are per se well-known compounds and extensively disclosed. Their use as surfactants in combination with other types of surfactants is also well-known.
  • EP-A-0341071 discloses detergent compositions which are particularly useful for manual dishwashing and which contain an alkyl polyglycoside surfactant, an anionic surfactant, a surface active betaine and/or amine oxide.
  • EP-A-250 181 and EP-A-364 744 discloses among other things in Example 9 a liquid shampoo composition comprising 2.7% of an anionic surfactant, 1.4% of an alkyl glycoside and a combination of a quaternary cocoamphocarboxyglycinate and 35% of a cocoamidopropylbetaine.
  • this composition contains two different amphoteric compounds with quaternary ammonium ions.
  • EP-A-364 744 relates to a detergent composition containing alkyl glycoside, dicarboxylic compound which could be either amphoteric or anionic.
  • dishwashing compositions are obtained when anionic tensides are used together with an alkyl polyglycoside and together with a combination of certain amphoteric compounds.
  • Liquid dishwashing compositions containing anionic surface active agents, alkyl polyglycoside and the combination of specific amphoteric compounds have extremely good mildness to skin and good foaming properties and they further give a low biological load and are more efficient than a dishwashing composition based on anionic tenside, an alkyl polyglycoside and an amphoteric alkyl betaine surfactant.
  • Dishwashing compositions according to the present invention are particularly suitable for manual washing, of glass, china, kitchen utensils etc, thanks to their mildness.

  • R is preferably an alkyl or alkenyl group and it is particularly preferred that R is a hydrocarbon group originating from coco, tallow or oleic fatty acid.
  • the amphoteric compounds of formula (I) can, as indicated, contain a group A which is a carbonyl group or one or several ethoxy- or propoxy-groups. When A is ethoxy or propoxy groups ethoxy groups are preferred and A is then especially one such group. Compounds which do not contain a group A, ie in which n is 0, are preferred.

  • Amphoteric compounds of the above given formulae are commercially available and sold under the trade name Ampholak (R) by Berol Nobel AB, Sweden.
  • the above combination of amphoteric compounds can partly replace anionic tensides and be used in liquid dishwashing compositions together with an alkyl polyglycoside to give very mild and efficient compositions with good foaming properties.
  • the mildness which is obtained is dependent not only on the use of the alkyl polyglycoside but also on an efficient detoxification of anionic tensides through formation of mixed micelles of the anionic surface active compounds and the specific amphoteric surface active compounds.
  • the very low critical micelle concentration for the specific amphoteric compounds is hereby utilized. The desired effect is thus obtained with very small amounts of amphoteric compound, particularly of those of the above given formulae I and II.
  • the alkyl polyglycosides, or sugar ethers, which are used in the present compositions are per se known nonionic surface active compounds which have a hydrophilic polysaccharide head group and a hydrophobic hydrocarbon substituent.
  • the hydrophilic saccharide units can for example be fructoside or glucoside units, glucoside units being preferred.
  • the alkyl polyglycosides suitably contain an average of from 1 to 5 saccharide units and preferably from 1.2 to 1.5 units.

  • an alkyl polyglycoside and anionic tensides which normally are water soluble sulfonates or sulfates, in liquid dishwashing compositions, the latter can be replaced to a certain extent and hereby a dishwashing composition is obtained which is advantageous from a biological point of view and advantageous with regard to mildness at use.
  • the present compositions also make it possible to substantially reduce the total amount of active components for obtaining the same dishwashing performance as with known compositions based on solely anionic tensides and as with compositions containing anionic tenside, can alkyl betaine amphoteric compound and an alkyl polyglycoside.
  • anionic tensides of the above mentioned types are also present, but in lower amounts than usual.
  • the total amount of amphoteric, nonionic and anionic surface active agents at most 90 per cent by weight are anionic tensides.
  • the amount of anionic tenside is suitably within the range of from 85 to 30 per cent by weight, based on the total amount of amphoteric surface active compounds, nonionic alkyl polyglycoside and anionic surface active compounds, and is particularly within the range of from 85 to 60 per cent by weight.
  • the anionic tensides are, as indicated above, water soluble sulfates or sulfonates, and then particularly alkyl sulfates, alkyl ether sulfates, alkyl sulfonates, alkyl aryl sulfonates, wherein the alkyl group usually contains from 8 to 22 carbon atoms.

These types of solvents are normally present, if at all present, in minor amounts. As some specific examples can be mentioned ethanol, isopropanol, ethylene glycol etc.. Solvents are sometimes included mainly for preservation.
  • One advantage of the present compositions is, however, that since they contain amphoteric compounds of the type according to formula (I) no solvent is required in order to obtain preservative effect.
  • the present dishwashing compositions can be prepared in per se conventional manner by simple mixing of the components and they can of course also be used in conventional manner. Normal dosage is about 0.2 g/l dish liquor of a dishwashing composition with a total dry content of from about 10 to about 45 per cent by weight.
  • the dishwashing compositions can of course also contain other conventionally used additives for improvement of different properties such as thickeners, antibacterial agents, colorants, pigments, perfumes etc..
  • Other amphoteric compounds can also be present if desired, such as betaines, and also other nonionic tensides.

  • Composition II according to the invention had the same efficiency index as the reference but for Composition IV according to the invention a considerably better efficiency was obtained in comparison with the reference Composition III.
  • Dishwashing performance of the compositions was assessed by the practical dishwashing tests. 1 ml beef tallow with an iodine number of 55.1 was applied on each plate and the plates were allowed to dry over one night at ambient temperature. 8 l of water with a concentration of 0.2 g/l of each tested composition and with a hardness of 20°dH were used at a temperature of 45+-2°C. After the initial generation of foam the dried plates covered with beef tallow were cleaned with a brush until the foam collapsed. The results were recorded as the number of washed plates and set in relation to the results obtained with composition 1.
