Definitions

  • Liquid washing, rinsing and cleaning agents are usually aqueous solutions of anionic and / or nonionic surfactants and customary additives. They are used for washing textiles, for cleaning hard surfaces, for example glasses or ceramic materials, plastics, lacquered and. polished surfaces, which can also be metallic in nature, are used. A preferred area of application for such agents is the manual washing of dining utensils and other related equipment. The respective cleaning processes are usually carried out at slightly elevated temperatures. There is always an increased impact on human skin.
  • the present invention therefore relates to cleaning agents with improved skin protection and strong washing power.
  • alkyl ether sulfates that is to say sulfated adducts of about 2 to 5 moles of ethylene oxide with fatty alcohols with about 10 to 16 carbon atoms in the alkyl radical, have good washing power and at the same time have a mild effect on the skin.
  • the commercially available dishwashing agents which are to be used manually are therefore aqueous solutions of such alkyl ether sulfates in combination with other anionic surfactants such as n-alkylbenzenesulfonates and / or alkanesulfonates, optionally also olefin sulfonates or alkyl sulfates and nonionic surfactants, solubilizers, colorants and fragrances.
  • alkyl ether sulfate mixture consisting of 50 percent by weight of a C 12 alkyl ether sulfate and 50 percent by weight of a C 4 alkyl ether sulfate with 1 to 5, preferably 2 to 4, ethylene oxide groups as ether component compared to the alkyl ether sulfate mixture normally used, that contains the same components in a weight ratio of 70:30 leads to an unexpected further reduction in skin irritation without reducing the known good washing power of such agents. Small additional amounts of alkyl ether sulfates with more or less than 12 or 14 carbon atoms in the alkyl radical change these good results only insignificantly, but should be avoided if possible.
  • betaine-type amphoteric surfactants have a mild effect on the skin. It was therefore expected that a combination of the mixture of C 12 / C 14 alkyl ether sulfates and betaines used according to the invention would show an additional increase in skin tolerance. However, this expected effect could not be determined. It was all the more surprising, however, that a significant increase in washing effectiveness could be achieved by further addition of such betaines.
  • the present invention therefore relates to a liquid cleaning agent based on an aqueous solution of anionic surfactants, optionally together with nonionic surfactants, solvents, solubilizers, corrosion inhibitors, preservatives, thickeners and colorants and fragrances, which is characterized in that it is 2 to 40 percent by weight a mixture of 50 parts by weight of a sulfated adduct of 1 to 5 ethylene oxide with an nC 12 alkanol and with an nC 14 alkanol and optionally up to 20 percent by weight of a surface-active betaine.
  • a preferred embodiment of the liquid cleaning agent according to the invention is characterized in that it contains 4 to 20 percent by weight of a mixture of 50 parts by weight of a sulfated adduct of 2 to 4 moles of ethylene oxide with an nC 12 alkanol and with an nC 14 alkanol and optionally 2 to 5 Contains percent by weight of a surfactant betaine.
  • composition of the aqueous cleaning agent solution according to the invention is as follows:
  • composition of the aqueous cleaning agent solution according to the invention is preferred:
  • alkyl ether sulfates with different chain lengths of the alkyl radicals or higher degrees of ethoxylation from those of the compounds according to the invention can be used as anionic surfactants.
  • anionic surfactants which can be used include n-alkylbenzenesulfonates with 9 to 16, preferably 12 carbon atoms in the alkyl radical, alkanesulfonates with 10 to 20, preferably 12 to 18 carbon atoms in the alkyl radical, olefin sulfonates with 12 to 16, preferably 12 to 14, carbon atoms in the n- Alkyl radical and alkyl sulfates having 8 to 18, preferably 8 to 14 carbon atoms in the alkyl radical.
  • R 1 is an alkyl radical with 8 to 20, preferably 10 to 18 carbon atoms and R 2 and R 3 , which may be interrupted by heteroatoms or heteroatom groups, and R 2 and R 3 are identical or different alkyl radicals having 1 to 3 carbon atoms.
  • R 1 is an alkyl radical with 8 to 20, preferably 10 to 18 carbon atoms and R 2 and R 3 , which may be interrupted by heteroatoms or heteroatom groups, and R 2 and R 3 are identical or different alkyl radicals having 1 to 3 carbon atoms.
  • C 10 -C 18 -Alkyl-dimethylcarboxymethylbetaine and C 11 -C 17 -Alkylamidopropyl-dimethylcarboxymethylbetaine are preferred.
  • the solvents to be added if necessary are low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably ethanol and isapropanol.
  • Solubilizers for example for dyes and perfume oils, can be used, for example, as alkanolamines, polyols such as ethylene glycol, 1,2-propylene glycol, glycerol and alkylbenzenesulfionates with 1 to 3 carbon atoms in the alkyl radical.
  • the preferred thickeners include urea, sodium chloride, ammonium chloride and magnesium chloride, which can also be used in combination.
  • corrosion inhibitors and preservatives are sodium benzoate, formaldehyde and sodium sulfite.
  • liquid cleaning agents according to the invention can also contain conventional disinfectants, since they have no effect on the skin-protecting effect of the alkyl ether sulfate mixture used in accordance with the invention.
  • liquid cleaning agents according to the invention of the following examples were obtained by stirring the individual components together in any order and leaving the mixture to stand until there were no bubbles.
  • the sodium salts were used as anionic surfactants.
  • EO means ethylene oxide.
  • Examples 1 to 6 were used for comparative experiments.
  • the sulfate mixture according to the invention was replaced in each case in equal quantities by a 70:30 C 12 - / C 14 alkyl (EO) 2 sulfate mixture.
  • the betaine was omitted and the surfactant proportions increased proportionately.
  • the comparison products correspond to commercially available cleaning agents. In all cases, skin irritation was determined according to the soap-chamber test (cf. "Journal of the American Academy of Dermatology" 1 [1979], pages 35 to 41).
  • the so-called plate test was also carried out.
  • the methodology is in the magazine »Fette; Soap; Anstrichsch «, 74 [1972], pages 163 to 165. It was mainly used with water of 45 ° C / 16 ° d and the use of 0.5 g / I product as well as a mixed contamination from protein, fat and carbohydrates.
  • the mixed soiling was used with 2 g / plate (saucer 14 cm in diameter; distributed in the cup recess); the soiled plates were rinsed after 15 hours of storage at ⁇ 0 to + 5 ° C under the conditions specified above.
