Definitions

  • LAS anionic linear alkylbenzenesulfonates
  • the material usually has a low bulk density, since the spray droplets expand in the spray tower due to the evaporation of water and form hollow spheres.
  • This product form makes difficult the production of compact detergents and the resulting powder also lacks good flowability, which makes transport difficult in the detergent manufacturing process.
  • the invention is based on the object to provide surfactant compounds which have a high flowability. It is also an object of the invention to convert linear alkylbenzenesulfonates from the liquid form into a solid, granular, readily flowable form.
  • the invention also relates to the use of the granular surfactant compounds according to the invention for the production of detergents and cleaners, including dishwashing detergents.
  • Brighteners are mixed in a quarter of the nonionic amount and mixed in household Multimixer (Braun) with half of the amount of soda.
  • household Multimixer Bran
  • the rest of the soda and the total quantities of zeolite and polymer are added at 300 rpm for 15 minutes. mixed.
  • half of the remaining nonionic is sprayed on in 5 minutes.
  • the SKS-6 is added and mixed for 10 minutes.
  • anionic, soap, antifoam, phosphonate and Opt Brightener are added and left for 10 minutes at 300 rpm. remixed.
  • the tumble mixer the mixture from the Lödigemischer is mixed with Perborat, TAED and enzymes under low shear stress and mixed for 15 minutes.
  • test fabrics are repeatedly (15 times) washed at 60 ° C. and a water hardness of 18 ° dH with this test detergent at a dosage of 65 g / wash.
  • the test fabrics are in particular a cotton terry (Vossen), in each case a cotton double ribbed, polyester / cotton blended fabric (type 20A) and standard cotton fabric (type 10A) from the company Wäschereiutz Testgewebe GmbH and a standard cotton fabric from the Eidgenössisches Materialprüfweg St. Gallen, Switzerland, additional laundry ballast (3.75 kg) is attached. After 15 washes, each of the fabrics is sampled and ashed in a muffle furnace at a temperature of 1000 ° C for a period of 24 hours.
  • SKS-6 powder was sieved as in Example 1.
  • the starting material had the following phase distribution: alpha disodium disilicate 5.6%, beta disodium disilicate 2.3%, delta disodium disilicate 90.4%, amorphous content 1.4% (wt .-%).
  • SKS-6 powder was sieved as in Example 1.
  • the starting material had the following phase distribution: alpha disodium disilicate 10.8%, beta disodium disilicate 4.4%, delta disodium disilicate 79.4%, amorphous content 5.4%.
  • this coarse-particle product was processed with Marlon A 375 to form a surfactant compound.
  • the surfactant compound had an ffc value of 6.8.
  • the further analysis data are listed in Table 1.
  • the ground product had the following phase distribution: alpha disodium disilicate 22.0%, beta disodium disilicate 12.1%, delta disodium disilicate 65.3%, amorphous content 0.6%.
  • the sieve residue test gave 20.3% residue.
  • test detergents a test compact color detergent with 20.8 wt .-% surfactant compound from Example 4 and 21.3 wt .-% commercially available SKS-6 powder (which corresponds to 35 wt .-% silicate and 7% by weight of linear alkylbenzenesulfonate).
  • SKS-6 powder which corresponds to 35 wt .-% silicate and 7% by weight of linear alkylbenzenesulfonate.
  • washing tests was used to investigate the formation of inorganic incrustations. The mean ash value of all five fabrics is 1.9%.
  • test detergents In accordance with the general procedure "preparation of the test detergents", a test compact heavy-duty detergent with 30.4% by weight of surfactant compound from Example 1 was prepared (corresponding to 20.3% by weight of silicate and 10% by weight of linear alkylbenzenesulfonate ). In model washing tests according to the general procedure "washing tests”, the formation of inorganic incrustations was investigated. The mean ash value of all five tissues is 2.2%.
