Definitions
- the invention relates to low-concentration and highly viscous aqueous surfactant preparations which contain alkyl glycosides and certain alkyl or alkenyl ether sulfates, a process for their preparation and the use of such preparations as detergents or cleaners.
- 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 conventional anionic surfactant in a ratio of 1:10 to 10: 1 are described in European patent application EP 070074.
- Detergents which contain alkyl glycosides and anionic surfactants are also known from European patent application EP 092 877.
- liquid detergents are known from European patent application EP 105556, which contain alkyl glycosides, certain other nonionic surfactants and anionic surfactants.
- From the international patent application WO 86/02943 alkylglycoside-containing liquid detergents are known which contain conventional anionic surfactants.
- a process for the production of alkyl glycosides using catalytic amounts of an anionic surfactant in its acid form is known from European patent application EP 132043.
- European patent application EP 132046 proposes to modify such a production process by adding certain bases after the actual reaction to neutralize the catalyst.
- the preparatory detergents or cleaning agents mentioned in these documents are relatively highly concentrated aqueous solutions or pastes, since the components intended for the mixture to give finished compositions should have the highest possible active substance content. At the same time, they must be easy to handle, which means that they should have the lowest possible viscosity, flow and be easy to pump.
- aqueous liquid products used by the consumer which include, in particular, liquid detergents, dishwashing detergents and universal cleaners, but also cosmetic products, for example hair shampoos or body-cleaning lotions, although the active substance content of such products is generally relative is low.
- Such products therefore normally contain thickeners, which generally have the disadvantage that they themselves do not contribute to the cleaning performance of the surfactant component contained in the agents.
- Typical thickeners are inorganic water-soluble salts, in particular sodium chloride, and salts of non-surface-active aromatic sulfonic acids, for example sodium cumene sulfonate.
- Organic thickeners are usually fatty acid alkanolamides, such as coconut fatty acid onoethanolamide, lauric acid monoethanolamide, oleic acid diethanolamide and coconut fatty acid diethanolamide, polyethylene glycol difatty acid esters and a number of water-soluble polymers.
- fatty acid alkanolamides such as coconut fatty acid onoethanolamide, lauric acid monoethanolamide, oleic acid diethanolamide and coconut fatty acid diethanolamide, polyethylene glycol difatty acid esters and a number of water-soluble polymers.
- agents which contain 15% by weight alkyl glycoside have a viscosity of less than 350 mPa.s at a content of approx. 0.5% by weight alkyl ether sulfate and the viscosity of such Agent goes through a minimum with the addition of increasing amounts of alkyl ether sulfate.
- agents are generally both too highly concentrated and not viscous enough to be regarded as easy to handle.

- the procedure is preferably such that an aqueous paste which contains alkyl glycoside of the formula I in a concentration of 30% by weight to 60% by weight is mixed in such an amount with the ether sulfate or with an aqueous solution of the ether sulfate, that the sum of the surfactants in the resulting aqueous preparation is 2.5% by weight to 10% by weight and the resulting gel contains 90% by weight to 97.5% by weight of water.
- the water can be mixed in at any point in the preparation of the agents according to the invention if the starting materials used do not already contain sufficient such solvent.
- the Components heated to temperatures of 60 ° C to 80 ° C and mixed with conventional mixers, which are preferably heatable and are kept during the entire mixing process, in particular at temperatures in the range mentioned.
- alkylglycosides suitable for the surfactant preparations according to the invention and their preparation are described, for example, in European patent applications EP 92355, EP 301 298, EP 357 969 and EP 362671 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, which include, in particular, glucose, mannose, fructose, galactose, talose, gulose, Altrose, Allose, Idose, Ribose, Arabinose, Xylose and Lyxose belong.
- 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) can also take non-integer numerical values as the quantity to be determined analytically; it is generally between 1 and 10, for the alkyl glycosides which are 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 portion (R1 in formula I) of the alkyl glycosides contained in the surfactant preparations 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, are also used to prepare usable alkyl glycosides can be. Accordingly, the primary alcohols with linear octyl, decyl, dodecyl, tetradecyl, hexadecyl or octa-decyl radicals and mixtures thereof are particularly useful.
- the alkyl glycosides can contain small amounts, for example 1 to 2%, of unreacted free fatty alcohol, which generally does not have a disadvantageous effect on the properties of the preparations produced therewith.
- ether sulfates which can be used in the context of the invention are anionic surfactants which, as a rule, are obtained by the known reaction of aliphatic primary alcohols with preferably 1 to 10, in particular 1 to 5, molar equivalents of alkylene oxide, in particular ethylene oxide, and subsequent reaction with a sulfating reagent, for example, sulfur trioxide or chlorosulfonic acid, and subsequent neutralization and hydrolysis of the reaction products formed, preferably with alkali, ammonium or alkyl or hydroxyalkyl-substituted ammonium bases.
- anionic surfactants which, as a rule, are obtained by the known reaction of aliphatic primary alcohols with preferably 1 to 10, in particular 1 to 5, molar equivalents of alkylene oxide, in particular ethylene oxide, and subsequent reaction with a sulfating reagent, for example, sulfur trioxide or chlorosulfonic acid, and subsequent neutralization and hydrolysis of the reaction products formed, preferably with alkali,
- Ether sulfates to which the process according to the invention extends are preferably derived from alkoxylated, in particular ethoxylated, fatty alcohols having 12 to 22 carbon atoms, in particular 12 to 18 carbon atoms.
- the degree of alkoxylation (q in formula II) is preferably 1 to 3.
- the degree of alkoxylation as a quantity to be determined analytically can also assume non-integer numerical values.
- Typical examples of starting materials for the ether sulfates which can be used according to the invention are lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol or behenyl alcohol and the corresponding unsaturated alcohols which can be obtained by reducing the carboxyl group from oleic acid, lauroleic acid, myristoleic acid, gadoleic acid, erucic acid, linoleic acid and linolenic acid.
- the ether sulfates can also be derived from technical alcohol mixtures, such as are obtained, for example, from the hydrogenation of technical fatty acid ester mixtures of natural origin or from aldehydes from Roelen's oxosynthesis.
- the ether sulfates produced in this way preferably contain as little as possible, in particular not more than 5% by weight, based on ether sulfate, of inorganic salt.
- ether sulfate include the alkali metal chlorides and in particular the alkali metal sulfates. If salt contents in such low amounts do not already occur in the production of the ether sulfates described above, The ether sulfate can be brought to contents not exceeding 5% by weight, in particular from 0.1% to 1.5% by weight, based in each case on ether sulfate, of inorganic salt by known methods, for example by recrystallization become.
- surfactant preparations according to the invention which contain such low-salt ether sulfate show a more pronounced, advantageous viscosity behavior in comparison with higher-salt ether sulfate, although the addition of inorganic salts, in particular sodium chloride, is usually considered to be thickening.
- Ether sulfates have long been known to be good anionic surfactants. However, it was surprising that the viscosity of dilute aqueous alkyl glycoside solutions can be increased significantly by adding very small amounts of such anionic surfactants. In contrast, the addition of alkylbenzenesulfonate as an example of another anionic surfactant, which is also known to have high cleaning performance, reduces the viscosity of dilute aqueous alkylglycoside solutions.
- the surfactant preparations according to the invention have excellent cleaning properties and high solubility in cold water. They are therefore preferably used as washing, rinsing or cleaning agents and in hair and body care or serve as storage-stable, easy-to-use premixes for the production of such agents.
- builder substances such as zeolites and phyllosilicates, corrosion inhibitors, bleaching agents, bleach activators, optical brighteners, enzymes, graying inhibitors, antimicrobial agents, abrasives, foam stabilizers, preservatives, pH regulators, opacifiers and pearlescent agents, colorants and fragrances and additional surfactants are possible among the preparations according to the invention. Examples
- Alkylglycoside to ether sulfate had the viscosities listed below (25 ° C, measured with a shear stress controlled rotation rheometer Carri-Med ( R ) CS 100 at a shear rate of 10 s ⁇ *), whereby for comparison also the values for equally concentrated ether sulfate free aqueous solutions are listed.
- Table 1 Properties of 5% by weight preparations (25 ° C)
- preparations not according to the invention which contained Ci2 / 14-alkyl glucoside and Na-Cn / 13-alkylbenzenesulfonate (Maranil ( R ), manufacturer Hüls). These had a viscosity of 270 mPa-s in 5% by weight solution (weight ratio 4.9: 0.1) and a viscosity of 360 mPa * s in 10% by weight solution (weight ratio 9: 1).
- the preparations according to the invention have significantly higher viscosities.
