  • the determination of the fat dissolving power was carried out according to the following test scheme.
  • the test soil used was a high-grease and oil-containing soil of the following composition (in% by weight) 2.5% coconut oil (Palmin) 2.5% beef tallow 2.5% olive oil 2.5% rapeseed oil 2.5% corn oil 2.5% milk powder 5% flour. 80% isopropanol
  • the mixture was stained with Sudan Red dye.
  • the soil mixture was freshly prepared before each experiment. As test objects to be cleaned, commercial white ceramic saucers with a diameter of 14 cm were used. The plates were cleaned in a commercial dishwashing machine prior to use and rubbed with ethyl acetate to remove residual fat and allowed to dry overnight. Twenty plates were used for each trial and marked on the bottom for unambiguous identification. The soil mixture was melted and 0.25 g of the liquid soil was applied evenly, circularly in a thin layer in the center of each plate. The plates are then dried at 40 ° C for twelve hours in a drying oven and weighed after cooling to room temperature.
  • the plates are fixed on a 22 ° inclined plane and poured with 20 ml of a temperature-controlled at 40 ° C rinse solution (0.02% active on surfactants).
  • the rinse solution is applied to the plate at a distance of 2 cm using a thin plastic tube at the top edge of the smudge.
  • the mixture was then rinsed with 20 ml of 40 ° C tempered water. Due to the inclined inclination of the dish, the detergent flows off with the detached and dispersed dirt.
  • the plates are then placed upright for two hours on a dish rack. This is followed by drying for 12 h in a drying oven at 40 ° C.
  • the plates are again balanced after cooling to room temperature. The difference of the plate masses with dirt before and after rinsing gives the cleaning power.
  • SLES Texapon® N 70 (trade name of BASF SE, sodium lauryl ether sulfate with 2 EO)
  • SL 18 Soporolipid from Ecover used, which has an acid to lactone ratio of 70:30 and a lactone form to oleic acid ratio of 60: 1.
  • the typical use concentration of formulations F1, F2, F4 and F5 as hand dishwashing detergents are 5 g formulation per 5 liters of water.
  • the typical use levels of formulation F3 as hand dishwashing detergent are 3g formulation to 5 liters of water.
