Definitions

  • This invention provides a stable concentrated aqueous or aqueous/alcohol solution of an alkyl ether sulphate useful as a component in formulating cleaning products especially dish washing liquids.
  • the solution contains alkaline earth metal ions, which are known to boost performance of dish washing formulations, but very few or no chloride or sulphate ions, which have a detrimental effect on the stability of concentrated solutions and on finished products made from said concentrated solutions.
  • the invention also describes a two-stage neutralising process for making such compositions.
  • composition may be used as a finished product in its own right, but preferably it will be mixed with other ingredients to produce a finished product. It is intended that the sulphating/neutralising processes may be carried out at locations remote from the sites were the finished product is blended. This allows for economical and flexible manufacturing and transportation.
  • compositions contain at least 1% of a semi polar nonionic surfactant
  • EP 039110 published November 4th, 1981, says that chloride and sulphate ions should be avoided or minimised because additional chloride or sulphate ions can increase the chill point temperature (the temperature at which inorganic salts precipitate as crystals in the finished product) .
  • EP 039110 deals with compositions of alkyl ether sulphate in combination with other surfactants, especially linear alkyl benzene sulphonate and alkyl sulphate in finished products. These finished products are not concentrated, and therefore the level of alkyl ether sulphate is around 10%. Neutralisation with mixed sodium/magnesium cations is disclosed.
  • EP 181212 published on May 14th, 1986, discloses that neutralisation of the alkyl ether sulphuric acid and the alkyl sulphuric acid can be carried out with the appropriate alkali or with a magnesium oxide or hydroxide slurry which avoids the addition of chloride or sulphate ions.
  • This publication also describes detergent compositions comprising 22% to 65% by weight of a surfactant system composed of a mixture of anionic, nonionic, and zwitterionic surfactants in an organic solubiliser/hydrotrope-water medium. However this disclosure is limited to less than 24% by weight of alkyl ether sulphate.
  • the composition contains alkaline earth metal ions which are known performance boosters in dish washing liquids.
  • the compositions contain a very low level, of chloride or sulphate ions.
  • An aqueous solution comprising from 50% to 90% by weight of alkyl ether sulphate which is associated with counterions chosen from alkali metal ions, alkaline earth metal ions or ammonium ions, or mixtures thereof, and which comprises at least 0.5% by weight of alkaline earth metal, preferably magnesium, ions and low levels of chloride or sulphate ions.
  • alkaline earth metal preferably magnesium, ions and low levels of chloride or sulphate ions.
  • the molar ratio of the alkaline earth metal to (the sum of chloride and inorganic sulphate) is greater than 1:1, preferably greater than 3:2.
  • compositions may be made by a neutralisation process comprising two stages.
  • the acid form of the alkyl ether sulphate is partly neutralised by a slurry of alkaline earth metal hydroxide, preferably magnesium hydroxide or alkaline earth metal, preferably magnesium oxide.
  • alkaline earth metal hydroxide preferably magnesium hydroxide or alkaline earth metal, preferably magnesium oxide.
  • further neutralisation is carried out in the presence of another alkali, such as sodium hydroxide.
  • either a short chain alcohol, a hydrotrope, or other surfactants may be present in either or both stages of the neutralisation for viscosity control and improved stability of the product.
  • Detergent compositions in accordance with the present invention comprise from 50% to 90% by weight, preferably
  • compositions comprise low levels of chloride or sulphate.
  • sulphate means SO4 2 -, either as an ion or as an i' ganic salt. The term excludes the sulphates of ethoxylated alcohols or other organic surfactants
  • the composition may also comprise from 0% to 20% of a short chain alcohol, a hydrotrope, other surfactants or a mixture of these.
  • a short chain alcohol e.g., ethanol or propylene glycol

  • Examples of naturally occurring materials from which the alcohols can be derived are coconut oil and palm kernel oil and the corresponding fatty acids.
  • C12-15 alkyl ether sulphates are preferred, and C12-13 alkyl ether sulphates are most preferred.
  • Blends can be made of material having different degrees of ethoxylation and/or different ethoxylate distributions arising from the specific ethoxylation techniques employed and subsequent processing steps such as distillation.
  • the average number of ethoxylate groups per molecule of alkyl ether sulphate should be less than 8, and preferably less than 4.
  • a average ethoxylation level of about 0.8 is particularly suitable for use in this invention.

  • the sulphation process may be carried out in a falling film reactor, or in a batch reactor, or in any other suitable sulphating equipment.
  • a continuous process using a falling film reactor is preferred in order to minimise degradation of the unstable acid surfactant prior to neutralisation.

Some of the neutralised product is then allowed to pass to the next process stage, whilst the rest is returned to the high shear mixer. Normally the fraction of product allowed to leave the loop and pass to the next processing stage is from 6% to 25% by weight, preferably from 9% to 17% by weight, whilst the remainder of the product continues around the loop.
  • the product at the exit of the heat exchanger shall be less than pH , preferably about pH3.
  • pH control may be effected by the addition of another alkaline solution into the first neutralisation loop, as well as the alkaline earth metal hydroxide/oxide.
  • the additional alkaline solution if present, is sodium, potassium, or ammonium hydroxide solution.
  • Viscosity may be controlled, if necessary, by addition of short chain alcohol, hydrotropes, or other ingredients commonly used in detergents, such as surfactants, into the first neutralisation loop.
  • the concentration of the intermediate product leaving the neutralisation loop may be adjusted by the addition of water to the neutralisation loop.
  • detergent ingredients may be added, such as nonionic surfactants and/or betaine.

  • the second neutralisation loop also comprises a high shear mixer, a pump and a heat exchanger.
  • the intermediate product from the first heat exchanger is mixed with an alkaline solution in the high shear mixer in order to complete the neutralisation.
  • the product leaving the neutralisation loop should be at least pH7, preferably from pH7 to pH9, most preferably about pH8.
  • alkaline solution Any suitable alkaline solution may be used in the second neutralisation loop, preferred alkaline solutions are sodium, potassium and ammonium hydroxide.
