Definitions

  • the present invention has also made it a point to further develop the modern washing and cleaning agents and to adapt them better to today's and foreseeable future requirements.
  • the primary goals are to enable the use of renewable raw materials and those from local sources to a greater extent than before by changing the surfactant base, to facilitate the production of the agents and at the same time to improve the application properties, in particular the cleaning ability and the dirt-carrying capacity of the fleet , as well as when used on fabrics to reduce incrustation and improve the grip of the washed fabrics.
  • an acylcyanamide salt with the general formula in which Me is sodium or potassium and R is an alkyl or alkenyl radical having 9-23 carbon atoms, which can be substituted by hydroxyl or alkoxyl groups, is used as the anionic surfactant.
  • this surfactant is much more similar to soaps than the synthetic anionic surfactants of the sulfonate or sulfate type which have been used almost exclusively for over 20 years. The suitability of the acylcyanamides for modern washing and cleaning agents was therefore not to be expected.
  • the present invention relates to a washing and cleaning agent for solid materials, in particular for textiles, which contains at least one synthetic anionic surfactant and at least one builder, also called builder, from the group of condensed phosphates and phosphate substitutes and, if appropriate, a nonionic surfactant and in which the Part or all of the anionic surfactants consists of an acylcyanamide salt of the formula defined above.
  • EP-A 24676 which describes a process for textile finishing, also includes the acylcyanamide salts of formula 1 in a very broad formula, but makes no reference to the surfactant properties of the compounds or to detergents.
  • the acylcyanamide grouping serves as a reactive group for fixing active substances to fibrous materials.
  • EP-A 8475 which describes a bleaching process and bleaching agent with cyanamines as activators
  • the acylcyanamide salts of the present invention are also included in a broad formula.
  • the cyanamines are used there with the aim of activating peroxide bleaching agents in order to increase the oxidizing power of the agents; no indication of surfactant properties is given.
  • acylcyanamide salts according to the invention can be obtained from carboxylic acid derivatives and cyanamide with subsequent neutralization by means of suitable bases [see German Patent 708428 or A.E. Kretov and A.P. Momsenko, J. org. Chem. (USSR) 1, 1765 (1965)].
  • the preparation is simpler by reacting salts of cyanamide with carboxylic acid esters, as described in EP-A 84836. This process can also be advantageous for the further use of the acylcyanamide salts in the production of detergents and cleaning agents, since it supplies the salts in anhydrous form.
  • Acyl cyanamide salts have the advantage that they can be produced from renewable raw materials, here fatty acid derivatives, and from cyanamide, which is easily accessible from calcium cyanamide.
  • these surfactants When using these surfactants, the detergent manufacturers' dependence on petroleum-based raw materials is reduced, which is noticeable, for example, with the most important anionic surfactant, alkylbenzenesulfonate.
  • acyl cyanamide salts are readily biodegradable and toxicologically safe.
  • the sodium salts of acylcyanamides have particularly favorable properties with regard to the aims of this invention, in particular those in which the radical R in the formula is an essentially unsubstituted alkyl or alkenyl radical having 11-17 carbon atoms.
  • Such salts can be easily prepared industrially from monosodium cyanamide and the methyl esters of natural fatty acid mixtures, such as tallow fatty acid methyl ester and palm kernel fatty acid methyl ester.
  • the agents according to the invention can be used in numerous fields of technology and the household for a wide variety of cleaning tasks.
  • fields of application are the cleaning of devices, apparatus, pipelines and vessels made of wood, plastic, metal, ceramic, glass etc. in industry or in commercial companies, the cleaning of furniture, walls, floors, objects made of ceramic, glass , Metal, wood, plastic, the cleaning of polished or painted surfaces in the household etc.
  • a particularly important area of application is the washing of all types of textiles in industry, in commercial laundries and in the household.
  • Suitable synthetic anionic surfactants which can be present in the agents according to the invention in addition to the acylcyanamide salts are, in particular, those of the sulfonate and sulfate type.
  • the surfactants of the sulfonate type are primarily the alkylbenzenesulfonates with C 9-15 -alkyl groups and the esters of a-sulfofatty acids, for example the a-sulfonated methyl or ethyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
  • alkanesulfonates which are obtainable from C 12 -C 18 -alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization or by bisulfite addition to olefins
  • olefinsulfonates which are mixtures of alkene and hydroxyalkanesulfonates and disulfonates as obtained for example from monoolefins with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
  • Particularly suitable surfactants of the sulfate type are the sulfuric acid monoesters of primary alcohols of natural and synthetic origin, ie of fatty alcohols such as e.g. Coconut fatty alcohols, tallow fatty alcohols, oleyl alcohol, or the C lo -C 2O oxo alcohols, and those of secondary alcohols of this chain length.
  • the sulfuric acid monoesters of the aliphatic primary alcohols ethoxylated with 1-6 mol ethylene oxide or ethoxylated secondary alcohols or alkylphenols are suitable.
  • Sulfated fatty acid alkanolamides and sulfated fatty acid monoglycerides are also suitable.
  • anionic surfactants are preferably used in the form of the salts, in particular in the form of the sodium salts, but also as potassium or ammonium salts or as soluble salts of organic bases, such as mono-, di- or triethanolamine.

  • non-or not fully water-soluble polyglycol ethers with 2-7 ethylene glycol ether residues in the molecule are also of interest, in particular if they are used together with water-soluble nonionic or anionic surfactants. Because of their good biodegradability, the ethoxylation products of primary aliphatic alkanols and alkenols are of particular practical interest.

  • the agents according to the invention contain, in addition to the surfactants, so-called builders, also called builders, whose task is to increase the cleaning action of the surfactants and to eliminate the negative effects of water hardness.
  • condensed phosphates especially pentasodium triphosphate, have had an excellent position among the framework substances.
  • These phosphates have excellent performance properties and can be present in the agents as the only framework substances. In these agents, however, they can also be replaced in whole or in part by phosphate substitutes, especially if the pollution of the waste water with the phosphates, which leads to the eutrophication of standing waters, is thereby reduced or avoided.
  • Inorganic and organic compounds which have a builder effect at least partially equivalent to sodium tripolyphosphate are suitable as phosphate substitutes.
  • the suitable water-soluble inorganic compounds are essentially the alkali carbonates and alkali silicates.
  • Useful water-soluble organic compounds can be found in the compound classes of the hydroxycarboxylic acids, aminocarboxylic acids, polycarboxylic acids, carboxyalkyl ethers, the polymeric polycarboxylic acids and the substituted and unsubstituted alkanedi- and polyphosphonic acids.
  • Typical examples of these classes of compounds are citric acid, nitrilotriacetic acid, mellitic acid, carboxymethyloxysuccinic acid, polyacrylic acid, polymethacrylic acid, poly-a-hydroxyacrylic acid, polymaleic acid and the corresponding copolymers and hydroxyethane diphosphonic acid. These compounds are mostly used in the form of their water-soluble salts.

  • the detergents and cleaning agents according to the invention show a surprisingly high dirt-carrying capacity as a further special property.
  • graying values can be achieved, for example, in textile washing, which are otherwise only observed in the presence of special graying inhibitors, which are generally high molecular weight polyionic compounds. This means that the use of graying inhibitors can be dispensed with entirely, thus considerably simplifying the detergent formulation.
  • the agents can also contain additional graying inhibitors and then achieve a higher dirt-carrying capacity in the liquor than conventional agents.
  • water-soluble colloids are suitable, such as, for example, the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
  • Water-soluble polyamides containing acidic groups are also suitable for this purpose.
  • Carboxymethylated cellulose or starch in the form of its sodium salts, methyl celluloses and polymers and copolymers of (meth) acrylic acid and maleic acid are preferred.
  • Soluble starch preparations and starch products other than those mentioned above can also be used, e.g. degraded starch, aldehyde starches, etc.
  • polyvinylpyrrolidone-type coloring inhibitors are useful.
  • Another surprising property of the detergents according to the invention is that they give the washed cotton textiles a significantly softer feel than conventional modern detergents. This can go so far that the incorporation of special softening agents, so-called finish substances, into the detergents, as is occasionally done today, and also a subsequent finish in the rinsing bath can be dispensed with. This effect is particularly evident in detergents in which the proportion of acylcyanamides is above 6% by weight, in particular above 12% by weight.
  • Bleaching agents can be contained in the washing and cleaning agents according to the invention in order to remove certain plant stains.
  • Known peroxide-type bleaching agents such as sodium perborate, sodium carbonate perhydrate, potassium peroxomonosulfate and organic percarboxylic acids are particularly suitable. These bleaches can be present alone or can also be used in conjunction with known stabilizers, such as magnesium silicate, sodium ethylenediaminetetraacetate or sodium salts of polyphosphonic acids, which have the task of preventing the premature decomposition of the per compounds by heavy metal salts and the damage to the tissues.
  • bleach activators can be used together with the bleaching agents.
  • anhydrides, carboxamides and carboxylic acid esters are particularly suitable as activators, which have an acylating effect on H 2 O 2 in the wash liquor and thus increase the bleaching power of the liquor.

  • washing and cleaning agents according to the invention can also contain other customary additives, in particular foam-regulating agents, enzymes, perfume oils, electrolytes, microbicidal agents and optical brighteners.
  • foam-inhibiting additives soaps with 20-24 carbon atoms, long-chain alkyl melamines, low-foam nonionic surfactants, paraffinic hydrocarbons, microcrystalline waxes and silicone defoamers.
  • Foam-damping soaps and silicone compounds are particularly important, here again the polysiloxanes activated by finely divided Si0 2 .
  • enzymes which can be used to enhance the cleaning action such as proteases, lipases and amylases, can be present as enzymes. Enzymes with an optimum activity in a pH range, as is achieved when the agents are used, and those enzymes which retain their action even at elevated temperatures are preferred.
  • Electrolytes can be contained in the agents for increasing the ionic strength in the application solutions, for pH regulation, as carriers or envelopes, for the desensitization of per compounds or even only as fillers.
  • These are preferably salts of sodium and potassium, for example sodium borate, sodium sulfate and potassium hydrogen phosphate, but can weak acids such as boric acid or bases such as ammonia can also be used.
  • Microbicides can be components of such agents, which should also have a disinfectant effect when used.
  • Typical bactericides and fungicides come into consideration as microbicides if they are compatible with the other components of the agents.
  • Optical brighteners are used in the agents according to the invention when it is a question of using these agents to increase the whiteness of the treated objects optically as well. Numerous compounds have been described in the literature as being useful for this purpose.
