Definitions

  • the present invention relates to concentrated surfactant mixtures of alkyl glycosides, long-chain alkyl sulfates, short-chain alkyl sulfates and optionally alcohol ethoxylates as stable, free-flowing and pumpable liquids and their use as premixes (compounds) for the production of liquid washing and cleaning agents.
  • alkyl glycosides with long-chain alkyl groups belong to the nonionic surfactants.
  • the person skilled in the art also knows, for example in A.M. Schwartz, J.W. Perry, Surface Active Agents, Vol. I, Interscience Publishers, 1949, page 372 described that surfactant mixtures generally have synergistic effects and often have better cleaning properties than would result from the sum of the values of the individual components.
  • Detergents which contain alkyl glycosides in combination with at least one customary anionic surfactant are described in European patent application EP 070 074. Detergents which contain alkyl glycosides and anionic surfactants are also known from European patent application EP 092 877. Furthermore, liquid detergents are known from European patent application EP 105 556, which contain alkyl glycosides, certain other nonionic surfactants and anionic surfactants. From international patent application W0 86/02943 alkylglycoside-containing liquid detergents are known which contain conventional anionic surfactants.
  • the individual components are generally used as flowable solutions, each of which contains a substance or which, as premixes, known as compounds, consist of several substances which are customary in the finished agents.
  • the components provided for the mixture into the finished agent should have the highest possible active substance content and at the same time be easy to handle, that is to say they should be as flowable and as possible be easy to pump and have the highest possible storage stability.
  • Alkyl glycosides are usually obtained as highly viscous pastes.
  • the object of the present invention was to develop a storage-stable, liquid, flowable and pumpable surfactant mixture from an alkyl glycoside paste.
  • This object is achieved by an aqueous mixture of certain amounts of alkyl glycoside, synthetic anionic surfactant in the form of a long-chain alkyl sulfate and short-chain alkyl sulfate.
  • long-chain compounds are understood to mean aliphatic compounds with 12 and more carbon atoms, which can be linear or branched one or more times, so that the longest chain of carbon atoms can also be shorter than 12.
  • Short-chain compounds in the context of the present invention are accordingly, regardless of the degree of branching, those having a maximum of 10 carbon atoms.
  • the compounds according to the invention are aqueous mixtures which consist essentially of 50 to 80% by weight, preferably 55 to 70% by weight of water, 5 to 30% by weight, preferably 10 to 25% by weight, of an alkyl glycoside of the formula I, R1-O (G) n (I) in which R1 is an alkyl radical having 8 to 22 carbon atoms, G is a glycose unit and n is a number between 1 and 10, 3 to 20% by weight, preferably 5 to 15% by weight, of a surface-active long-chain alkyl sulfate of the formula II, R2-O-SO3X (II) in which R2 is an alkyl radical having 12 to 22 carbon atoms and X is an alkali metal or ammonium ion, and 1 to 15% by weight, preferably 2 to 10% by weight, of a short-chain alkyl sulfate of the formula III, R3-O-SO3Y (III) in which R3 is an alkyl radical having 6 to 10 carbon
  • the surfactant mixtures according to the invention preferably additionally contain 10 to 20% by weight, in particular 12 to 18% by weight, of an ethoxylated alcohol of the formula IV, R4O- (CH2CH2O) p -H (IV) in which R4 is an alkyl radical having 10 to 22 carbon atoms and p is a number between 1 and 20, in particular between 3 and 10.
  • alkyl glycosides suitable for the surfactant mixtures according to the invention and their preparation are described, for example, in European patent applications EP 92 355, EP 301 298, EP 357 969 and EP 362 671 or the US Pat. No. 3,547,828.
  • the glycoside components ((G) n in formula I) of such alkyl glycosides are oligomers or polymers from naturally occurring aldose or ketose monomers, in particular glucose, mannose, fructose, galactose, talose, gulose, altrose, allose , Idose, ribose, arabinose, xylose and lyxose.
  • the oligomers consisting of such glycosidically linked monomers are characterized not only by the type of sugar they contain, but also by their number, the so-called degree of oligomerization.
  • the degree of oligomerization (n in formula I) generally assumes fractional numerical values as the quantity to be determined analytically; it is between 1 and 10, for the alkyl glycosides preferably used below 1.5, in particular between 1.2 and 1.4.
  • the preferred monomer building block is glucose because of its good availability.
  • the alkyl part (R 1 in formula I) of the alkyl glycosides contained in the surfactant mixtures according to the invention preferably also originates from Easily accessible derivatives of renewable raw materials, in particular from fatty alcohols, although their branched chain isomers, in particular so-called oxo alcohols, can also be used to produce usable alkyl glycosides.
  • the primary alcohols with linear octyl, decyl, dodecyl, tetradecyl, hexadecyl or octadecyl radicals and mixtures thereof are particularly useful.
  • the alkyl glycosides can contain small amounts, for example 1 to 2%, of unconverted free long-chain alcohol, which does not have a disadvantageous effect on the properties of the surfactant mixtures produced therewith.
  • Long-chain alkyl sulfates suitable for use in the surfactant mixtures according to the invention are the sulfation products of linear or branched chain alcohols.
  • the derivatives of fatty alcohols with 12 to 22 C atoms, in particular with 12 to 16 C atoms, are particularly suitable.
  • Such alkyl sulfates have long been known as effective anionic surfactants.
  • Suitable short-chain alkyl sulfates are the sulfation products of linear or branched chain alcohols with 6 to 10 carbon atoms, preferably the derivatives of linear alcohols with 8 to 10 carbon atoms. Such alkyl sulfates are known to have little or no surfactant activity.
  • the alkyl sulfates can be prepared in a known manner by reacting the corresponding long- or short-chain alcohol component with a customary sulfating agent, in particular sulfur trioxide or chlorosulfonic acid, and subsequent neutralization, preferably with alkali, ammonium or alkyl or hydroxyalkyl-substituted ammonium bases.
  • a customary sulfating agent in particular sulfur trioxide or chlorosulfonic acid
  • the ethoxylates suitable for use in the compounds according to the invention are derivatives of linear or branched-chain alcohols having 10 to 22 carbon atoms, preferably 12 to 16 carbon atoms.
  • the degree of ethoxylation the alcohols (p in formula IV) are between 1 and 20, preferably between 3 and 10. They can be prepared in a known manner by reacting the corresponding alcohols with ethylene oxide.
  • the preparation of the surfactant mixtures according to the invention presents no difficulties. It can be done easily by simply mixing the individual components, which can be present as such or preferably in aqueous solution.
  • the mixtures according to the invention are notable for their low viscosities, their easy flowability and pumpability and their high storage stability.
  • the viscosity of the compounds according to the invention is generally from 20 mPa.s to 7000 mPa.s. They generally have basic pH values, for example from 9.8 to 10.5, but can be adjusted to largely neutral to weakly acidic pH values by adding conventional acids, in particular citric acid, without losing their advantageous properties .
  • the compounds according to the invention are stable in storage over a long period of time, at least 30 days, at temperatures of about 1 ° C. to about 45 ° C.
  • Another unexpected advantage of the compounds according to the invention is that the improvement in the rheological properties of the surfactant alkyl sulfate alkyl glycoside pastes is achieved by the addition of compounds which, despite their low surface activity, have the properties of the alkyl glycoside pastes relevant to use in end products, such as cleaning and Foaming power, do not negatively affect.
  • the compounds according to the invention can be used, directly or after dilution with water, for technical applications, for example as flotation aids or drilling fluids. However, they are preferably used as premixes for the production of liquid detergents and cleaning agents, which include, in particular, mild detergents, wool detergents and dishwashing detergents, but also shampoos. Such agents can be prepared in a simple manner by diluting the compounds with water to the desired active substance concentration.
  • compositions customary in such compositions, to which in particular builder substances, such as zeolites and layered silicates, corrosion inhibitors, bleaching agents, bleach activators, optical brighteners, enzymes, graying inhibitors, antimicrobial agents, water-miscible solvents, abrasives, foam stabilizers, preservatives, pH regulators, colorants and fragrances as well as additional surfactants are possible.
  • builder substances such as zeolites and layered silicates, corrosion inhibitors, bleaching agents, bleach activators, optical brighteners, enzymes, graying inhibitors, antimicrobial agents, water-miscible solvents, abrasives, foam stabilizers, preservatives, pH regulators, colorants and fragrances as well as additional surfactants are possible.
  • the surfactant mixtures M1 to M7 according to the invention characterized below in Table 1 by their composition and the compositions V1 and V2 used in comparative experiments were prepared.
  • the surfactant mixtures M1 to M7 according to the invention had pH values of 9.8 to 10.5, and their pH values in 8.5% by weight aqueous solution were 8.5 to 9.9.
  • Samples of the mixtures M1 to M7 according to the invention were stored at 1 ° C. or 10 ° C. for 30 days without a change in their consistency being found. When stored at 40 ° C for 30 days, slight cloudiness occurred in some cases, which disappeared when cooling to room temperature. If the compounds according to the invention were adjusted to pH values of 6.0 to 8.8 by adding small amounts of citric acid, which did not significantly change their viscosity, they could be stored at temperatures up to 45 ° C. without changing the consistency.
