  • one or more other - especially in hand dishwashing detergents - common auxiliaries and additives, in particular UV stabilizers, perfume, pearlescent agents (INCI opacifying agents; for example glycol distearate, for example Cutina ® AGS from Cognis, or mixtures containing this, for example Euperlane ® from Cognis), dyes, corrosion inhibitors, preservatives (e.g.
  • bronopol the technical 2-bromo-2-nitropropane-1,3-diol, also known as bronopol ( CAS 52-51-7 ), which is commercially available, for example, as Myacide ® BT or as Boots Bronopol BT from Boots) or Acticide MBR 1 or Acticide CMB 2, organic salts, disinfectants, pH adjusters and additives that improve skin feel or care for the skin (e.g. dermatologically active substances such as vitamin A, vitamin B2, vitamin B12, vitamin C, vitamin E, D panthenol, sericerin, collagen partial hydrolyzate, various vegetable protein partial hydrolysates, protein hydrolyzate fatty acid condensates, liposomes, cholesterol, vegetable and animal oils such as e.g.
  • dermatologically active substances such as vitamin A, vitamin B2, vitamin B12, vitamin C, vitamin E, D panthenol, sericerin, collagen partial hydrolyzate, various vegetable protein partial hydrolysates, protein hydrolyzate fatty acid condensates
  • lecithin soybean oil, etc.
  • plant extracts such as aloe vera, azulene, witch hazel extracts, algae extracts, etc., allantoin, AHA complexes, glycerin, urea, quaternized hydroxyethyl cellulose), in amounts usually not more than 8% by weight based on the total weight of the dishwashing detergent.
  • Na-xylenesulfonate can be used as an additive.
  • the pH value of the agent according to the invention can be adjusted using conventional pH regulators, for example acids such as mineral acids or citric acid and/or alkalis such as sodium or potassium hydroxide, with a range of 4 to 9 - particularly if hand tolerance is desired.
  • acids such as mineral acids or citric acid
  • alkalis such as sodium or potassium hydroxide
  • the agent according to the invention can contain one or more buffer substances (INCI buffering agents), usually in amounts of 0.001 to 5% by weight, preferably 0.005 to 3% by weight, in particular 0 .01 to 2% by weight, particularly preferably 0.05 to 1% by weight, most preferably 0.1 to 0.5% by weight, for example 0.2% by weight.
  • buffer substances that are also complexing agents or even chelating agents (chelators, INCI chelating agents) are preferred.
  • Particularly preferred buffer substances are citric acid or citrates, in particular sodium and potassium citrates, for example trisodium citrate 2 H2O and tripotassium citrate H2O.
  • Table 1 The example compositions shown in Table 1 were provided using a basic formulation comprising 6.4% by weight anionic surfactant and 1.6% amine oxide surfactant. The total amount of surfactant is therefore 8% by weight. The recipe also contained smaller amounts of fragrances and dyes as well as protease and amylase enzymes. Table 1 Example Reference symbols EtOH C.S AM / LM total NaCl C1 10 0 0.6 13 4.4 E1 50 1.5 0.6 4 6.7 E2 30 0.75 0.6 6 5.27 E3 40 1,125 0.6 5 6 E4 80 1.5 0.6 4 7.65 E5 70 1.5 0.6 4 7.2
  • compositions result from the values in Table 1 and the basic recipe.
  • the solvent includes ethanol and cumene sulfonate, CS.
  • the table also shows the ratio of the total amount of surfactant to the total amount of solvent.
  • the viscosity curves are in Figure 1 shown.
  • the example recipes E1 to E5 according to the invention show that the compositions according to the invention in particular have a good viscosity profile in the skin-friendly pH range of at least 7.
  • the viscosities of the compositions are such that the consumer perceives the compositions to be of high quality and the viscosity within the relevant pH range has a relatively small/stable change depending on the pH value.
  • the homogeneous mixing of the components using stirring tools was possible sufficiently well.
  • the comparison formulation C1 showed an unsuitable viscosity profile. High viscosity values could be achieved. In contrast to the example recipes according to the invention, however, these were not sufficiently constant/stable depending on the pH value. The manufacturing process of such a composition is made considerably more difficult or even impossible due to the viscosity peaks, since sufficient mixing of the composition using stirring tools is prevented.
  • composition E2 has a slight peak in viscosity.
  • the ratio of total surfactant content to solvent is 6. Therefore, according to a preferred embodiment, a ratio of total surfactant content to solvent is described which is less than 10, in particular 4 and 5, as is the case in examples E1, E3, E4, and E5 is.
  • example compositions with a higher total surfactant content were provided.
  • the corresponding example compositions shown in Table 2 were provided using a basic recipe comprising 16% by weight anionic surfactant and 4% amine oxide surfactant. The total amount of surfactant is therefore 20% by weight.
  • the recipe also contained smaller amounts of fragrances and dyes as well as protease and amylase enzymes.
  • Table 2 Example Reference symbols EtOH C.S AM / LM total NaCl C2 110 1 1 10 1,875 E6 150 3.9 1 4 4.9
  • compositions result from the values in Table 2 and the basic recipe.
  • the solvent includes ethanol and cumene sulfonate, CS.
  • the table also shows the ratio of the total amount of surfactant to the total amount of solvent.
  • the viscosity curves are in Figure 2 shown.
  • the comparison formulation C2 showed an even more pronounced viscosity peak than in the compositions with lower total surfactant amounts C1.
  • the problem already presented applies particularly to higher total surfactant contents.
  • composition E6 according to the invention is characterized by a particularly stable viscosity profile. Compared to the recipes E1 to E5 with a lower total surfactant content, even better stabilization of the viscosity is achieved.
  • the advantageous stabilization of the viscosity curve occurs particularly at higher total surfactant amounts of at least 12% by weight.
  • the ratio of total surfactant content to solvent is also preferably less than 10, in particular between 4 and 6, more preferably 4 or 5.
