Definitions

  • the invention relates to aqueous detergent concentrates which, after dilution, preferably after mixing with the desired quantity of water, can be used for cleaning, amongst other things, dishes and fabrics.
  • the concentrates consist of an aqueous solution containing at least three components with cleansing action. These components, which will be specified in greater detail below, are collectively referred to by the term "active detergent".
  • Concentrates are convenient for storage and transport, but for the final users it is of course the properties of the washing liquid obtained by dilution that are important. There is a danger that dilution can cause the viscosity to drop excessively, especially if the active detergent consists of alkylaryl sulphonate and one or more polyethyleneglycol ethers of primary or secondary higher alcohols and/or of alkylphenols. A large viscosity drop on dilution is unacceptable for buyers of the detergent concentrates, especially housewives, and should therefore be avoided.
  • the invention therefore relates to an aqueous detergent concentrate, characterized in that in addition to water it contains an active detergent comprising the following components.
  • the detergent concentrate preferably contains at least 10% wt, and in most cases not more than 70% wt, relative to the weight of the concentrate, of the active detergent.
  • the salts of component (a) and (c) are preferably alkali, ammonium and/or amine salts.
  • Alkali salts are most preferred, especially sodium salts.
  • Component (a) is preferably a salt of an alkylbenzene sulphonic acid, especially one with 8-16 carbon atoms in the alkyl group.
  • the carbon atoms in the alkyl group in component (a) preferably form a straight chain.
  • the polyethyleneglycol ethers of primary or secondary alcohols in component (b) satisfy the general formula (R-(OC2H4)"OH, in which R is an alkyl group with 8-18 carbon atoms and n represents an integer varying from 5 to 12.
  • R is an alkyl group with 8-18 carbon atoms and n represents an integer varying from 5 to 12.
  • the carbon atoms in the alkyl group R preferably form a straight chain.
  • the salts of components (c) are preferably alkali, ammonium and/or amine salts. Alkali salts are most preferred, especially sodium salts.
  • the alcohol from which component (c) is derived is preferably a primary or secondary alcohol. The carbon atoms in this alkanol preferably form a straight chain.
  • component (d) consisting of one or more salts of sulphated alcohol ethoxylates and/or of sulphated alkylphenolethoxylates.
  • the salts of component (d) are preferably alkali, ammonium and/or amine salts. Alkali salts are most preferred, especially sodium salts.
  • Component (d) is preferably a sulphated alcohol ethoxylate, such as the sulphated ethoxylate of primary or secondary alcohols with straight or branched chains, especially of alcohol mixtures.
  • Component (d) is preferably a sulphated ethoxylate of C e -C, 8 alkanols, especially of C,2-C,e alkanols.
  • the alkanols are preferably primary and have mainly straight chains, i.e. they are less than 30% branched.
  • the most satisfactory alcohols are obtained by hydroformylation of olefins.
  • the sulphated ethoxylates are prepared from these alcohols by first reaching them with ethylene oxide, suitably in such a quantity that on average 1 to 15, especially 2 to 4 mol ethylene oxide per mol alcohol (or alcohol mixture) is added, followed by sulphation of the ethoxylate and neutralization to the sulphated alcohol ethoxylate.
  • Suitable sulphated alkylphenolethoxylates are sulphated C4-C,s alkylphenolethoxylates with an average of 1 to 12, especially 1 to 5 mol ethylene oxide per mol alkylphenol. Mixtures of sulphated alcohol ethoxylates and sulphated alkylphenolethoxylates can be used.
  • composition of the aqueous detergent concentrate according to the invention contains an active detergent comprising 50-70% wt of component (a) 5-30% wt of component (b) and 0.1-25% wt of component (c).
  • Component (d), if present, is preferably present in a quantity of 0.1-25% wt.
  • the most preferred concentrates contain 50-70% wt of component (a), 15-25% wt of component (b), 1-25% wt of component (c) and 5-25% wt of component (d). All weight percentages are calculated as activce detergent component on the total of the active detergent.
  • the previously mentioned viscosity drop on dilution while retaining a low transparency point is reduced even more by the presence of MgS0 4 in the concentrate.
  • the quantity of MgS0 4 absorbed in the detergent concentrates depends on the nature and the quantities of the other constituents, as well as on the desired viscosity in undiluted and diluted state. In general, preference is given to quantities between 0.05 and 10% wt relative to the weight of the aqueous concentrate.
  • An additional advantage of the present invention is that in general no solubilizing agent needs to be added to this aqueous detergent concentrate in order to improve the solubility of the active detergent, so that the composition of the concentrates remains homogeneous during transport and storage, provided that the temperature does not drop to abnormally low levels.
  • a useful criterion in practice is to assume that the transparency point should not be above about 5°C. If it is nevertheless desired to add a solubilizing agent, use can be made of, for example, urea, alkanols with 1-4 carbon atoms per molecule, e.g.
  • 2-propanol and the sodium, potassium, and ammonium salts of arylsulphonic acids substituted with one or more alkyl groups having 1-4 carbon atoms, such as toluene sulphonic acid and xylene sulphonic acid.
  • arylsulphonic acids substituted with one or more alkyl groups having 1-4 carbon atoms, such as toluene sulphonic acid and xylene sulphonic acid.
  • an alkali salt of an alkyl-substituted aryl sulphonic acid e.g. sodium xylene sulphonate
  • a lower alcohol e.g. 2-propanol.
  • the content of solubilizing agent in the concentrates is preferably between 0 and 30% wt, calculated on the total quantity of active detergent.
  • Component (a) was the sodium salt of "DOBANIC ACID".
  • DOBANIC ACID is a trade mark for a mixture of n-alkylbenze sulphonic acids with 8-13 carbon atoms in the alkyl group.
  • the intermediate product used for its preparation, C S -C 13 alkylbenzene, was obtained by alkylation of benzene with a mixture of C S -C 13 olefins obtained by thermal cracking of paraffin wax. These olefins consisted mainly of olefins with a terminal double carbon-carbon bond.
  • Component (b) was "DOBANOL” 91-8.
  • “DOBANOL” 91-8 is a trade mark for a mixture of polyethyleneglycol ethers obtained by ethoxylation linear primary alkanols with 9-11 carbon atoms per molecule and which contain an average of 8 ethylene oxide groups per molecule. The alkanols consist mainly of 80% straight-chained and 20% alkyl (mainly 2-methyl) isomers.
  • Component (c) was "TEEPOL:HB6".
  • “TEEPOL:HB6” is a trademark for an aqueous solution of a mixture of sodium salts of sulphated primary alkanols.
  • Component (d) was "DOBANOL” 25-3S”.
  • DOBANOL 25 ⁇ 3S is a trade mark for a mixture of polyethyleneglycol ethers obtained by ethoxylation of linear primary alkanols with 12-15 carbon atoms per molecule and which contains an average of 3 ethylene oxide groups per molecule.
  • detergent concentrates were prepared by mixing, at room temperature, water and the components listed in Table II.
  • Component (a) contained for the sodium salt of "DOBANIC ACID".
  • Components (b), (c) and (d) were the same as those used in examples 1-8. From each of these concentrates were prepared three diluted aqueous solutions, containing 37, 35 and 30 weight per cent active detergent.
