Definitions

  • Liquid cleaning agents usually consist of aqueous solutions of synthetic anionic and / or nonionic surfactants and customary 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 in slightly diluted liquors at slightly elevated temperatures of around 35 to 45 ° C.
  • the cleaning power of an agent is judged by the consumer as the better, the stronger and the longer the cleaning liquor foams. Because the hands come into contact with the cleaning liquor over a longer period of time, the detergent's skin-friendliness is also of particular importance when washing dishes. 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.
  • the present invention relates to a liquid, manually applicable, skin-friendly dishwashing detergent with strong foaming and good cleaning power.
  • alkyl ether sulfates that is to say salts of sulfated adducts of about 2 to 5 moles of ethylene oxide with fatty alcohols having about 8 to 18, preferably about 12 to 16, carbon atoms in the aliphatic radical have good foaming and cleaning power and have skin-friendly properties.
  • the commercially available, manual dishwashing detergents are therefore generally aqueous solutions of such alkyl ether sulfates in conjunction with other surfactants, in particular alkylbenzenesulfonates and solubilizers, colorants and fragrances.
  • liquid cleaning agents for manual dishwashing are known, which are a combination of an alkyl ether sulfate and a nonionic surfactant of the fatty acid alkanol type consisting of mono- or dialkanolamides with no more than 3 carbon atoms in each alkanol residue and saturated fatty acids with 10 to 14 carbon atoms, together with water, solubilizers, colorants and fragrances.
  • European patent application 70 076 discloses foaming liquid cleaning agents containing anionic surfactants, alkyl glucosides and fatty acid alkanolamides.
  • liquid detergents for the manual cleaning of dishes which contain synthetic anionic surfactants of the sulfonate and / or sulfate surfactant type, fatty acid alkanolamides and certain fatty alkyl glucosides.
  • the foaming and cleaning power of liquid cleaning agents which are specifically designed for manual cleaning of dishes and the synthetic anionic surfactants of the sulfonate and / or sulfate surfactant type and nonionic surfactants of the fatty acid alkanolamide type , Contain alkyl polyglycol ethers and / or fatty alkyl glycosides, which can be enhanced by using fatty acid aminopropanediol amides as fatty acid alkanolamides or in addition to known fatty acid alkanolamides.
  • the fatty acid residue has about 8 to 18, preferably about 10 to 14 carbon atoms in the alkyl chain. These compounds are used in an amount of about 1 to 15, preferably about 1 to 5 percent by weight, based on the total agent.
  • the aminopropanediolamides are prepared by reacting 1- or 2-aminopropanediol with fatty acids or esters of the fatty acids by known processes, for example preferably by base-catalyzed reaction of fatty acid methyl esters with 1-aminopropanediol at temperatures between about 110 and 180 ° C. while distilling off releasing methanol. Solubility tests showed that the more hydrophilic amides from 1-aminopropanediol are more soluble in water than the corresponding derivatives of monoethanolamine, an effect which leads to clear advantages of the more soluble aminopropanediolamides because of the relatively poor solubility of known fatty acid amides.
  • alkyl sulfates and / or alkyl ether sulfates are used as synthetic anionic surfactants.
  • anionic surfactants which have a petrochemical base, in particular no alkylbenzenesulfonate, are used, which, however, are also usable for the purposes of the invention.
  • the anionic surfactants are preferably used as sodium salts. Up to about 50% of the sodium ions can also be replaced by magnesium ions, which increases the skin-friendliness.
  • alkyl sulfates used or the corresponding alkyl ether sulfates are commercially available, they have an aliphatic C12-C18, preferably Ci2-Ci4 radical.
  • the associated cation is preferably an alkali, alkaline earth or ammonium ion.
  • the degree of ethoxylation is about 1 to 5, preferably about 2 to 4. Minor additional amounts of alkyl ether sulfates with less than 12 or more than 14 carbon atoms in the alkyl radical change these good results only insignificantly, but should preferably be avoided .
  • the amount of alkyl and / or alkyl ether sulfates used is about 3 to 40, preferably about 5 to 20 percent by weight, based on the total agent.
  • the amount of the Cs-Ciö-alkylglycosides which can be used according to the invention with about 1-2, preferably about 1-1.6 glucose units in the molecule can be about 0.1 to 10, preferably about 1 to 5 percent by weight, based on the total agent.
  • the proportion of all nonionic surfactants in the dishwashing detergent, including the aminopropanediol amides, is about 1 to 20, preferably about 1.5 to 15,% by weight, based on the total detergent, the weight ratio of aminopropanediol amides to optionally further nonionic surfactants being about 1 : 3 to 1: 0.5, preferably about 1: 1.
  • alkanols such as ethylene glycol, propylene glycol 1,2 or glycerol, and as hydrotropes alkali alkylbenzenesulfonates having 1 to 3 carbon atoms in the alkyl radical, preferably sodium cumene sulfonate, can serve as solubilizers, for example for dyes and perfume oils, for example.
  • solubilizers for example for dyes and perfume oils, for example.
  • the amounts used are between about 0 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 ethanol, n-propanol and isopropyl alcohol, can also be used. Their amounts then also amount to about 0 to 10 percent by weight, based on the total agent.
  • Thickeners such as urea or neutral salts, and electrolytes, such as sodium chloride, ammonium chloride and magnesium chloride, can also be used individually or in combination.
  • Further customary optional additives are corrosion inhibitors, preservatives, dyes and perfume oils.
  • the remainder to be calculated for a total of 100 percent by weight for the total medium consists of water.
  • liquid cleaning agents according to the invention according to the following examples were obtained by stirring the individual constituents together and leaving the mixture to stand until there were no bubbles.
  • Texapon ( R ) N C ⁇ 2 / 14-Alky1 (E0) 2-5-sulfate, Na salt
  • APG ( R ) 600 Ci2 / i4 alkyl polyglucoside with about 1.4 GE
