Definitions

• Liquid cleaning agents usually consist of aqueous solutions of synthetic anionic and / or nonionic surfactants and conventional additives. They are particularly used for cleaning hard surfaces, for example glass, ceramic materials, plastics, painted and polished surfaces.
• An important area of application for liquid cleaning agents is the manual washing of eating and cooking utensils.
• the dishes are usually cleaned at slightly elevated temperatures of around 35 to 45 ° C in very dilute liquors.
• the cleaning power of an agent is rated by the consumer the better and the longer the cleaning liquor foams. Because of the contact of the hands with the cleaning liquor over a longer period of time, the skin-friendliness of the agent is of particular importance when washing dishes manually. For these reasons, the expert makes different considerations when selecting the components and the composition of an agent for the manual cleaning of dishes than with liquid detergents for other hard surfaces.
• alkyl ether sulfates that is to say salts of sulfated adducts of about 2 to 5 moles of ethylene oxide with fatty alcohols of about 10 to 18, are preferred wise 12 to 16 carbon atoms in the aliphatic rest have good foaming and cleaning power as well as skin-friendly properties.
• the commercially available, manual dishwashing detergents also known as dishwashing detergents
• dishwashing detergents therefore generally represent aqueous solutions of such alkyl ether sulfates in conjunction with other surfactants, in particular alkylbenzenesulfonates, and solubilizers, colorants and fragrances.
• Swiss patent 354 195 discloses liquid detergents for manual dishwashing, which are a combination of an alkyl ether sulfate and a nonionic surfactant of the fatty acid alkanolamide type from mono- or dialkanolamides with no more than 3 carbon atoms in each alkanol residue of saturated fatty acids with 10 to 14 Contain carbon atoms, together with water, solubilizers, colors and fragrances.
• European patent application 70 076 discloses foaming liquid detergents containing anionic surfactants, alkyl glucosides and amine oxides or fatty acid alkanolamides, the alkyl glucosides being alkyl oligoglucosides which contain the glucose unit about 1.5 to 10 times. This value is an average value and also takes into account the presence of alkyl monoglucosides in a corresponding proportion. Alkyl glucosides with a degree of oligomerization of higher than 2 are found to be particularly suitable.
• German patent application P 35 34 082.7 describes a liquid cleaning agent for manual cleaning of dishes, containing synthetic anionic surfactants of the sulfonate and / or sulfate type, fatty acid alkanolamides and fatty alkyl glucosides, which is characterized in that it contains fatty alkyl glucosides of the fatty alkyl monoglucoside type contains on average less than 2 glucoside units per fatty alkyl radical, in particular 1 to 1.4 glucoside units.
• Detergents in particular dishwashing detergents, containing di-n-alkylsulfosuccinates have long been known.
• dishwashing detergents which contain alkyl ether sulfates and sulfosuccinates, preferably di-n-octyl sulfosuccinate, and, if appropriate, further surfactants are described in German patent specification 23 17 076.
• aqueous mixture of alkyl sulfosuccinates and alkyl ether sulfates is also known from European patent application 124367. It also describes aqueous solutions of alkyl sulfosuccinates alone and of alkyl sulfosuccinates in a mixture with alkyl benzene sulfonates.
• the foaming and cleaning power of liquid, optionally aqueous, cleaning agents which are specially designed for the manual cleaning of dishes and which essentially contain alkyl glucosides can be increased by giving them di-alkylsulfosuccinates with 7 to 9 , in particular 8 carbon atoms in the alkyl group puts.
• the alkyl radical can be straight-chain or branched.
• the proportion of di-alkyl sulfosuccinates is 20 to 90, preferably 50 to 80 parts by weight, based on the total surfactant content of 15 to 50% by weight in the product. They are present as alkali, especially as sodium salts.
• the proportion of alkyl glucosides with 10 to 18, preferably 12 to 14 carbon atoms in the alkyl radical and with 1 to 5, preferably 1 to 1.4 glucose units (GE) in the molecule in the agents according to the invention is accordingly 10 to 80, preferably 20 to 50 parts by weight. based on the total surfactant content of 15 to 50 wt .-% in the product.
• anionic surfactants preferably alkyl ether sulfates or alkyl sulfates - and amphoteric surfactants such as.
• B Acylamidopropyldimethylammoniumbetain performance improvements in washability and improvements in storage stability can be achieved.
• compositions according to the invention are preferably free from the proportions of anionic surfactants based on petrochemicals, such as, for example, which are generally customary for such compositions.
• anionic surfactants based on petrochemicals, such as, for example, which are generally customary for such compositions.
• Alkanolamines, polyols, such as ethylene glycol, 1,2-propylene glycol or glycerol and, for example, hydrotropic alkali-alkylbenzenesulfonates with 1 to 3 carbon atoms in the alkyl radical, such as sodium cumolsulfonate, can serve as solubilizers, for example for small amounts of dye and perfume oil.
• the amounts used are then generally between 1 and 10 percent by weight, based on the total agent.
• solvents such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably etha nol and isopropyl alcohol used.
• solvents such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably etha nol and isopropyl alcohol used.
• the amounts used are also 3 to 15 percent by weight, based on the total agent.
• Viscosity regulators such as urea, sodium chloride, ammonium chloride, magnesium chloride and sodium citrate can also be used individually or in combination.
• Other common optional additives are corrosion inhibitors, preservatives, dyes and perfume oils.
• a remainder, to be calculated for a total of 100 percent by weight, for the total composition consists of water.
• liquid cleaning agents according to the invention according to the following examples were obtained by stirring the individual constituents together and allowing the mixture to stand until there were no bubbles.
• the sodium salts were used as sulfosuccinates.
• the plate test is described in this example.
• the amount of 27 g of di-isooctylsulfosuccinate was stirred at room temperature with 15 g of isopropanol in 55 g of water. And with further stirring, 3 g of C 12/14 alkyl glucoside with 1.1 glucose units (GE) were added in the molecule.
• the product was clear and had a viscosity of 30 mPas determined according to Höppler at 20 ° C.
• saucers were coated with 2 g of melted beef tallow (test soil A). Then 8 liters of tap water (16 ° d) at 50 ° C was placed in a bowl.
• a solution of 10 g of di-isooctylsulfosuccinate, 4 g of C 12/14 alkyl glucoside GE, 1.4.6 g of C 12/14 alkyl ether sulfate with 2 ethylene oxide groups, 10 g of isopropanol and 70 g of water was, according to Example 1, in a plate test with 0 , 6 g detergent / l rinsing solution. Of the plates soiled with test soil (B), 27 plates were rinsed clean. However, if 2 g of the alkyl ether sulfate were replaced by 2 g of C 8/18 acylamidopropyldimethylammonium betaine (Dehyton K®), 30 plates were rinsed clean.
• test series also carried out in analogy to Example 1, show the influence of the degree of oligomerization of the C 12/14 alkyl glucoside on the rinsing performance in combination with di-n-octylsulfosuccinate. Note the decrease in the rinsing performance with increasing degree of oligomerization of the alkyl glucoside in mixed soiling (B).
