Dishwashing Liquid – Foam Stability & Oil Loading

This research evaluates foam stability for a dishwashing liquid under increasing oil loading. Goal: keep stable foam and cleaning feel as oil content rises.

Method: Incremental oil addition was applied during standardized hand-wash simulation. Foam height and collapse time were recorded.

Conclusion: Foam remains stable at low oil loads; performance declines sharply at high loads. Consider amphoteric booster.
