Benefits of technology

[0005]The present invention relates to an automatic dishwashing detergent composition. The composition comprises from about 0.1% to about 20% by weight of the composition of a high foaming surfactant; from about 0.5% to about 15% by weight of the composition of a low foaming non-ionic surfactant; from about 0.001% to about 5% by weight of the composit

Problems solved by technology

The pump action makes the dishwashing operation prone to foam formation.
Foam can easily overflow the low sills of the dishwashing machines and slow down or stop the arm rotation due to having air and foam filling the arms instead of water, which in turn reduces the cleaning action and can even bring the dishwasher to a halt.
Therefore, in the field of automatic dishwashing machines the use of foam-producing detergent components is normally restricted.
However, as noted hereinbefore, automatic dishwashing detergent compositions have the unique limita

[0092]Example 1 shows the maximum foam value for various simplified detergent compositions, including a high foaming non-ionic surfactant (MARLIPAL 24 / 70® from Sasol Corporation, Foam volume=346 mL), a low foaming non-ionic surfactant (PLURAFAC SLF180® by the BASF-Wyandotte Corp, Foam volume=0 mL), and / or a silicon based suds suppressor (KS-530® from Shin-Etsu Chemical Industry Co).

[0093]The suds suppressing action of the combination of Plurafac SLF180 and Shin-Etsu KS530 (composition D) is much higher than the level of suds suppressing action when using either Shin-Etsu (composition B) or Plurafac SLF180 (composition C) alone.
