  • Table 7 Foam heights at start point in the presence of oil belonging to example 1 and comparative example 1.
  • Example 1 produces high foam height which is the indication of foaming strength of dishwashing compositions in the presence of oil.
  • Comparative example 1 containing strong and irritating surfactants produces very close foam heights as milder surfactants in the presence of oil.
  • anionic surfactants like LABS-Na and SLES are used to boost the cleaning performance of the composition in the presence of oil and grease, they produces foam heights very close to the present invention composition which containing less amount of mild, non-irritating MES surfactant.
  • high foam height in the presence of oil can be obtained by the inclusion of mild, non-irritating and naturally derived surfactants.
  • example 1 represents concrete evidence that high foam height in the presence of oil can be obtained with dishwashing compositions involving mild, non-irritating compositions rather than compositions involving strong and irritating surfactants.
  • Foam duration measurement is the time period measure between the starting point (as above) and breaking point of stable foam period. Foam duration is the time period lapsed between starting point of foam height measurement at starting point (as above) and the breaking point of the foam, whereas breaking point is defined as the time point where significant decrease of foam height occurs.
  • Table 8 Foam Durations belonging to example 1 and comperative examples 1.
  • Example 1 has the most persistent foam height which is an indicator of foam strength. With %1.8 foam height decrease it is by far the best composition with respect of foam duration which is indicative for better cleaning performance as well.
  • Comparative example 1 is empowered with the inclusion of strong anionic surfactants which creates big bubbles and high foam height at the beginning of the cleaning process but they perish after short period of time. Therefore, the percent decrease of foam height in comparative example 1 is 8.3 which way higher than example 1.
  • present invention composition has better foam duration properties in comparison with comparative example 1.
  • Present invention composition produces high foam durability with low foam decrease with the inclusion of controlled proportions of specific surfactants which are mild, non- irritating.
  • example 1 represents a concrete evidence that high foam duration with low foam decrease can be obtained with dishwashing compositions involving mild, non-irritating surfactants rather than compositions involving strong and irritating surfactants.
  • Foam height is measured at the breaking point of stable foams. Breaking point of stable foam is determined at the start of rapid fall of stable foam and foam height at that point is measured.
  • Example 1 the preferred composition of present invention, has high foam height as comparative example 1 at breaking point with low (1.8%) foam height decrease which is indicative for foaming strength.
  • Comparative example 1 has high foam height at breaking point but with high (8.3%) foam height decrease.
  • composition involving LABS-Na SLES seems to provide better cleaning performance by creating big bubbles and high foam height at the beginning of the cleaning process, the bubbles and foam height are perished after a short period of time.
  • high foam height at breaking point with low (1.8%) foam height decrease can be obtained by the inclusion of mild, non-irritating and naturally derived surfactants.
  • example 1 represents concrete evidence that high foam height at breaking point with low decrease of foam height can be obtained with dishwashing compositions involving mild, non-irritating compositions rather than compositions involving strong and irritating surfactants.
  • TOC sample procedure was performed as follows: 11 pieces detergent solution have been dissolved according to I KW Standart Test Method with 3.03 gr detergent in 5 It water. Foaming has been achieved with pouring water from 1 m height according to standard. 10 pieces white porcalein dishes have been put in the prepared solution and each one have been holded for one minute. Rinsing have been performed for each dishes 5 times front part, 5 times back part and 5 times front part again during 7 seconds with 550 gr water, under 4500 g/min flowrate. Dishes have been put on a flat surface to be dried. Rinsed dishes have been holded in 10 L water for 1 hour. Water samples have been taken from the rinsing solution (1 L water) for each washed and rinsed plate samples. (For each detergent 1 sample has been taken).
