Definitions

  • Such cleaning agents are unsuitable as rinse aid.
  • limescale or silicate deposits can form on the dishes and in the interior of the machine, since the calcium binding capacity of these cleaners is lower than that of the classic phosphate-containing products. Disturbing lime or silicate deposits occur in particular if the washing water in the dishwasher is not or not sufficiently softened and a water hardness of 4 ° dH is exceeded. In such cases, limescale or silicate deposits can be effectively avoided if citric acid is dosed into the rinse aid via the rinse aid.
  • rinse aid formulations for machine dishwashing which contain only one surfactant and only alkyl polyglycosides and as a further Be Ingredients contain defoamers and thickeners. The usual acid levels in rinse aid are missing.
  • alkyl polyglycosides are generally strong foaming agents and, in the rinse aid formulations described, would cause an unacceptable foam load when used in the dishwasher.
  • defoamers are only effective if they do not dissolve in the medium to be defoamed. Therefore, the alkyl polyglycoside solutions and the defoamers in the rinse aid examples listed are not miscible with one another. There would therefore be two phases if a thickener which ensured a certain homogenization had not been used to disperse them.
  • the low temperature is necessary because warehouses are usually not heated in winter. Temperatures around freezing are therefore quite realistic. On the other hand, as long as they are homogeneous, the known products are so viscous that they cannot be poured in via the rinse aid dosing device of a household dishwasher.
  • Rinse aid formulations that contain only alkyl polyglycosides as a surfactant component do not wet the rest of the plastic wash ware or only very little, so that the rinse aid or drying effect is not satisfactory with these materials.
  • mixtures of alkyl polyglycosides and alkyl polyglycol ethers or mixtures of alkyl polyglycosides and modified alkyl polyglycol ethers (end-capped fatty alcohol ethoxylates) or mixtures of alkyl polyglycosides, alkyl polyglycol ethers and modified alkyl polyglycol ethers with organic carboxylic acids do not have such disadvantages with regard to a biological product, but rather the requirements of a biological product Complete degradation as well as the application properties.
  • rinse aid according to the invention is that for the preparation of their homogeneous solutions no further, mostly inert and therefore ineffective solubilizers for drying and the rinse aid effect, such as. B. sodium cumene sulfonate or ethanol or glucose syrup are required, unless they are required in small quantities for the incorporation of colorants and / or fragrances.
  • Short-chain alkyl polyglycosides (C 8 -C 12 ), such as, for. B. APG (R) 225 (Henkel), Lutensol (R) GD 70 (BASF).
  • the amount of alkyl polyglycoside in the rinse aid according to the invention is about 0.5 to 15, preferably about 1 to 10,% by weight.
  • Suitable alkyl polyglycol ethers are, for example, Henkel's dehydol types such as Dehydol (R) LS 2, Dehydol (R) LS 4, Dehydol (R) LS 5 and Dehydol (R) LT 2, Dehydol (R) LT 3 and Dehydol (R ) LT 4.
  • the Dehydol (R) products of the LS series are EO adducts with fatty alcohols with a chain length in the range C12-C14 and the LT series are those in the chain length range C 12 -C 18 .
  • dehydol (R) 100 (Ci2-Ci8 fatty alcohol * 9 E0) and dehydol (R) 980 (C ⁇ o-Ci4 fatty alcohol * 6 E0).
  • Modified alkyl polyglycol ethers are e.g. B. with a butyl group end-capped alkyl polyglycol such as. B. Dehypon (R) LS 104, Dehypon (R) LT 104 and Dehypon (R) LT 054 from Henkel.
  • the weight ratio of alkyl polyglycosides to alkyl polyglycol ethers is about 3: 1 to 1: 1.5, preferably about 2: 1 to 1.5: 1.
  • organic carboxylic acids come aliphatic hydroxy-di- and tricarboxylic acids such as malic acid (monohydroxysuccinic acid), tartaric acid (dihydroxysuccinic acid); saturated aliphatic dicarboxylic acids such as oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid; Gluconic acid (hexane-pentahydroxy-1-carboxylic acid), but preferably anhydrous citric acid. They are used in amounts of about 1 to 50, preferably from about 1 to 30,% by weight.
  • the foam development of the rinse aid was determined with the aid of a circulating pressure measuring device.
  • the rinse aid (3 ml) was dosed by hand in the rinse aid at 50 ° C.
  • the dishwasher door was fully opened 15 minutes after the end of the washing program. After 5 minutes the drying was determined by counting the remaining drops on the dishes listed below.
  • agents according to the invention were compared with those according to EP 432 836 and an alkylpolyglycoside-free formulation.
  • Lutensol (R) GD 70 alkyl polyglycoside (from BASF)
  • Keltrol (R) F Thickener: high molecular polysaccharide
  • Keltrol (R) S xanthan gums
  • Rinse aid dosage 3 ml
  • toppings remaining after the rinse cycle were assessed according to a points scheme:
  • Rinse aid * 4.4 / 5.8 4.0 / 7.0 5.2 / 8.0 5.0 / 5.5
  • Table 1 shows the composition and foam development of the formulations 1-11 according to the invention and the formulations according to the prior art A - D during the rinse cycle.
  • the rinse aid (recipes A, C, D) formulated with defoamer according to EP 432836 did not cause foaming.
  • recipes 1 - 4 which were formulated exclusively with APG (R) 225, only resulted in a low and tolerable foam formation in the household dishwasher.
  • the defoamer-free formulation with the APG 60 ⁇ (R) (B) resulted in strong, intolerable foam formation.
  • Table 2 shows the drying effect of formulations 1-11 and A, C and D. This table shows that the drying effect was best for rinse aid formulations containing an APG / alkylpolyglycol ether combination or a combination of APG / alkylpolyglycol ether and modified alkylpolyglycol ether. This advantage in terms of application is particularly evident in the case of plastic tableware.
  • Table 2 also shows the rinse aid effect of formulations 1-11 and A, C and D.
  • the rinse aid effect was significantly better for formulations 5 - 8 and 11, which contained APG (R) 225 / alkyl polyglycol ether combinations or a combination of APG (R) , alkyl polyglycol ether and modified alkyl polyglycol ether, than for the only APG (R) 225- containing formulations 1 -4 and A, C and D.
  • the formulations according to the invention require no defoamers, no thickeners for stabilization and no solubilizers. In addition, they show a rinse aid and drying effect that corresponds to the common market goods. Compared to the formulations described in European patent application 432836, the combination of APG (R) 225 and alkyl polyglycol ethers or modified alkyl polyglycol ethers has significantly improved the rinse aid and drying effect in plastic dishes.
  • Table 3 shows the scale-reducing effects of various rinse aid formulations containing citric acid.
  • recipe 8 contains 3% citric acid, recipe 530%, recipe 640% and recipe 750%.
  • phase stability 40 g of rinse aid were slowly heated to 60 ° C. If no phase separation or turbidity was observed during this process and at the temperature end point, the rinse aid formulation met the required phase stability.
  • Table 4 provides information about the thermal phase stability and the foam development in the rinse aid of rinse aid formulations according to the invention.
  • Solution brokers such as B. sodium cumene sulfonate or ethanol were used
