Cleaning Composition Rapid Foam Collapse via Hansen Solubility

The patent changes the chemical composition parameters of the cleaning formulation by incorporating specific compounds (e.g., citrus-based solvents, surfactants with balanced HLB values) that modify foam stability characteristics. This allows the foam to maintain sufficient stability for cleaning indication while incorporating ingredients that promote faster collapse after application, thus resolving the contradiction between cleaning efficacy and rinse properties.

The invention uses composite cleaning formulations that combine multiple ingredients with complementary properties - surfactants for foam generation, specific solvents for controlled foam stability, and rinse aids that accelerate foam collapse. This composite approach allows simultaneous optimization of both foam persistence for cleaning indication and rapid collapse for easy rinsing.

The foam in the cleaning composition is designed to exhibit periodic behavior - initially stable to provide visual confirmation of cleaning action, then transitioning to rapid collapse for easy rinsing. This time-dependent foam behavior creates a natural sequence where foam stability serves the cleaning indication function first, then automatically transitions to the rinse phase, resolving the contradiction between consumer perception and ease of operation.

The patent introduces specific intermediary compounds (such as citrus-derived solvents and foam modifiers) that act as mediators between the surfactant system and the foam structure. These intermediaries control the foam's lifecycle - maintaining it long enough for visual indication but facilitating its collapse for easy rinsing, thus bridging the gap between consumer perception and operational ease.
