Definitions

  • This invention relates to detergent particularly but not exclusively for use in domestic dishwashing although it may find industrial or alternative domestic applications.
  • Percentage compositions used in this specification are by weight unless indicated otherwise.
  • a mobile liquid detergent comprising not more than 8% water and not less than 90% of active detergents including an anionic surface active agent, an ethanolamide derivative of coconut oil and a non-ionic polyether, wherein a 0.01 % w/w solution of the active detergent exhibits a surface tension at 20°C of not more than 4.5x 10- 2 Nm- 2 (45 dyne cm-1) characterised in that the said mobile liquid detergent contains a total of not less than 50% of the ethanolamide derivative of coconut oil and the non-ionic polyether, and in that the liquid detergent may be diluted to form an aqueous solution having a strength in the range 7 to 50% by weight, which has a viscosity not less than 2 ⁇ 10 -4 m 2 s -1 (200 centistokes) in the absence of an inorganic thickening agent.
  • the viscosities are determined at 20°C.
  • An active detergent is a surface active agent, an 0.01 % aqueous solution of which exhibits a surface tension at 20°C of not more than 4.5 ⁇ 10 -2 Nm -1 (45 dyne/cm).
  • Preferred detergents in accordance with this invention comprise not less than 92% active detergent, not more than 1% polyethylene glycol and not more than 4% glycerine.
  • Detergents in accordance with this invention have an advantage that they do not contain a large proportion of water, thereby facilitating economical transportion and packing. Furthermore, use of inactive thickening agents such as sodium chloride in compositions which have been diluted for use is unnecessary since detergents in accordance with this invention thicken upon dilution with water alone.
  • a preferred high foaming composition may be diluted to a 15% to 45% aqueous solution having a viscosity not less than 2x10-4m2s-1 (200 centistokes) and being capable of passing a dishwashing and foam test as hereinafter defined.
  • the non-ionic polyether may comprise an alkylphenyl polyether or a polyether derivative of an alcohol.
  • Preferred alcohol polyethers may be derived from C 13 /C 15 or C 17 /C 18 aliphatic alcohols or from mixtures of oleyl and cetyl alcohols.
  • compositions may be diluted to 8% to 10% of their strength to produce solutions preferably having viscosities of 5 ⁇ 10 -4 to 10 ⁇ 10 -4 m 2 s -1 (500 to 1000 centistokes), but solutions showing viscosities up to 20 ⁇ 10 -4 m 2 s -1 (2000 centistokes) may also be obtained.
  • the dishwashing and foam test is performed as follows. Sodium chloride (2.5%), gelatine (2.5%), caramel (5%), instant potato (9.5%), fat (Trex or Tesco (Registered Trade Mark) lard 68%), and water (12.5%) are warmed and mixed together. The mixture is placed in a refrigerator for 24 hours and is removed from the refrigerator at least 30 minutes before use. A portion (5 g) of the mixture is applied to the surface of each plate used in the test and the plates are then left to stand for 1 hour. The plates are 23 cm in diameter and are white in colour.
  • a portion (0.5 g) of the detergent solution is placed in one end of a polyethylene bowl having internal dimensions of 33 cmx29 cm and a depth of 13 cm and which is inclined at an angle of 25° to the horizontal.
  • Water (5 1) at a temperature of 54°C is allowed to run onto the detergent through an aperture 6 mm in diameter located 40 cm above the detergent.
  • the bowl is arranged horizontally when half of the water has been added and the remaining water is allowed to pour into the opposite end of the bowl thereby providing a good foam covering the entire water surface.
  • a second bowl is filled with water for rinsing the plates. Two soiled plates are immersed into the water and a stopclock is immediately started. After 20 seconds the first plate is washed and rinsed.
  • a third plate is then immersed below the second plate and the second plate is then washed.
  • a fourth plate is then immersed below the third and the process is repeated until there is no foam remaining on the surface of the water.
  • the final temperature of the water must not be less than 45°C. The test is repeated ten times and the mean taken.
  • the detergent passes this test if eight or more plates can be washed before the foam dissipates when using a diluted solution equivalent to a maximum concentration of 0.01 % of the concentrated detergent.
  • the ethanolamide derivative of coconut oil may be a monoethanolamide or diethanolamide derivative. These may be formed by reacting coconut oil or the methyl ester thereof with either monoethanolamine or diethanolamine in the presence of sodium methoxide.
  • the major constituent of coconut oil is the triglyceride of dodecanoic acid although shorter and longer chain triglycerides are also present.
  • the anionic detergent is a salt of dodecylbenzenesulphonic acid or a mixture of salts of alkylbenzenesulphonic acids of which a major constituent is dodecylbenzenesulphonic acid. Suitable mixtures may be either broad cut or narrow cut, that is there may be greater or lesser variation in the lengths of the alkyl chains. Narrow cut mixtures are preferred.
  • the dodecylbenzenesulphonate is soft. There should be no propylene tetramer present.
  • the anionic detergent may comprise an alkyl sulphate, or an alkyl ether sulphate.

  • the latter may be formed by reacting an alkyl phenol with ethylene oxide.
  • Preferred polyethers incorporate nonyl or octyl alkyl chains or mixtures including major proportions of such chains.
  • Preferred polyethers may comprise mixtures of polyether chains with major proportions of chains having 6 or 9 (CH 2 CH 2 0) units or, more preferably, major proportions of both 6 and 9 (CH 2 CH 2 0) unit containing chains. A greater proportion of chains having 6 (CH 2 CH 2 0) units to chains having 9 (CH 2 CH 2 0) units is particularly preferred. Smaller proportions of polyethers with larger ether chain lengths may be incorporated for example having 12 (CH 2 CH 2 0) units.
  • Preferred detergents in accordance with this invention incorporate a base.
  • Preferred bases include monoethanolamine, diethanolamine, triethanolamine or potassium or sodium hydroxides. Monoethanolamine and triethanolamine are particularly preferred.
  • Detergents in accordance with this invention may be selected from a wide range of compositions in which the proportions of the ingredients are chosen so that they may be diluted to form an aqueous solution having a strength in the range 7 to 50% by weight, which has a viscosity of at least 2x10-4m2s-' (200 centistokes) in the absence of an inorganic thickening agent, and which has adequate cleaning properties in accordance with the plate washing test.
  • the ratio of anionic detergent to nonionic detergent is important, an excess of nonionic detergent being essential.
  • the ratio of anionic detergent to insoluble polyethers is also important, a greater proportion of anionic detergent having been found to increase the solubility of the polyether constituent.
  • the detergent composition of this invention incorporates not more than 30% of anionic detergent estimated as the free acid. More preferably there is between 15% and 25% of dodecylbenzenesulphonic acid present in detergents which do not contain alkyl or ether sulphates. If the latter compounds are present the preferred proportion of dodecylbenzenesulphonic acid is 8% to 25%.
  • the proportion of alkyl or ether sulphate is preferably 10% to 30% based on the weight of the commercially available solutions, the latter containing approximately 70% of the pure compounds.
  • the proportion of the ethanolamide derivative of coconut oil has an important effect of the viscosity of the detergent.
  • the derivative also serves to stabilise the foam.
  • alkylphenyl polyethers having a side chain incorporating a small number of (CH 2 CH 2 0) groups is a key factor effecting the viscosity of detergents in accordance with the invention.
  • such polyethers alone may be insoluble in water.
  • the cloud point of the insoluble polyether is less than zero.
  • Mixtures incorporating nonylphenyl polyether are particularly preferred ingredients, a wide range of ether chain lengths being advantageous.
  • Nonylphenyl polyethers are particularly efficacious in control of the viscosity of the diluted detergent.
  • Nonylphenyl polyethers having a low solubility in water, notably those comprising six (CH 2 CH 2 0) groups are particularly preferred as a major proportion of total polyethers in the detergent.
  • Preferred detergent compositions of this invention incorporate between 25% and 55% of nonylphenyl polyether. More preferably there is between 40% and 55% of the polyether.
  • Detergent compositions of this invention often incorporate a blend of nonylphenyl polyethers.
  • s (300 cp) may comprise 1 ⁇ 5% of nonylphenyl polyether incorporating 12 (CH 2 CH 2 O) units, 25 ⁇ 45% of nonylphenyl polyether incorporating 6 (CH 2 CH 2 0) units and 2-10% of nonylphenyl polyethers having 8 or 9 (CH 2 CH 2 0) units.
  • the actual percentages of these three components are chosen so that the total percentage of polyether falls within the aforementioned range of 25-55%.
  • a particular efficacious range for the three aforementioned polyethers is 1-3% with 12 (CH 2 CH 2 0) units, 30-45% with 6 (CH 2 CH 2 0) units and 5-10% with 8 or 9 (CH 2 CH 2 0) units.
  • Bases having a low molecular weight are preferred, monoethanolamine having been found to provide more viscous detergents than diethanolamine.
  • Use of triethanolamine has the advantage of maintaining a constant pH in the detergent.
  • Ethanolamines may be used in conjunction with sodium or potassium hydroxides, the ratio of alkali metal hydroxide to ethanolamine being important.
  • the amount of mono-, di- and triethanolamine present is approximately 1.0­1.5 ⁇ the stoichiometric amount based on the sulphonate and sulphate present being desirable.
  • the amount of mono, di- or triethanolamine is preferably selected so that a 10% aqueous solution of the detergent has a pH of 6.8 to 9, more preferably of 7.5 to 8.5.
  • a relatively larger proportion of diethanolamine or triethanolamine is required if this reagent is used in place of ethanolamine since the mono derivative is the most active.
  • Detergent in accordance with this invention may be diluted to form aqueous solutions of more than 7% strength, for example 8%, 10%, 20%, 25% and 40%.
  • a particular preferred detergent comprises ingredients not exceeding a total of 100% and comprising, 7% to 30% of dodecylbenzenesulphonic acid, 10% to 30% of a solution equivalent to a 70% solution of anionic detergent of the formula: wherein n is 13 or 15 and m is 3; X is Na or NH 4 or an ethanolamine, 25% to 50% of nonylphenyl polyether; 5% to 40% of coconut oil diethanolamide and residual percentages of ethanolamine and triethanolamine.
