Effervescing Toilet Tablets for Malodor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet cleaning compositions fail to effectively control malodors emanating from toilets, particularly after use, due to residual urine and fecal deposits, and do not provide a rapid and sustained fragrance release.
Innovation Solution
An effervescing composition comprising an anhydrous gas generator system, bulking constituents, starch, proteolytic enzyme, fragrance, and minimal water, formulated into a tablet form that rapidly effervesces in toilet water, releasing gases and fragrance to neutralize odors and create a hydrophobic film, thereby trapping malodors.

Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional toilet cleaning compositions are used, then basic cleaning function is provided, but malodor control is ineffective and fragrance release is not rapid or sustained
Solution Approach 1:
The patent transforms the composition from a conventional static formulation to an effervescing system that undergoes parameter changes (phase transition, gas evolution, pH change) upon contact with water. This enables rapid fragrance release and effective malodor neutralization through the generation of carbon dioxide bubbles that carry fragrance compounds and create a hydrophobic film, resolving the contradiction between basic cleaning function and effective malodor control
Solution Approach 2:
The composition utilizes phase transitions through the effervescing reaction where solid acid and carbonate components react with water to produce gaseous carbon dioxide. This phase transition creates rapid bubble formation that releases fragrance compounds and forms a hydrophobic film on water surface, providing both rapid fragrance release and sustained malodor control, thereby improving reliability of odor neutralization
2Speed
If effervescing compositions with gas generator system are used, then rapid fragrance release and malodor control are achieved, but composition complexity increases
Solution Approach 1:
The patent merges multiple functions into a single effervescing tablet composition: cleaning (through pH adjustment), fragrance release (through gas evolution carrying aromatic compounds), and malodor control (through hydrophobic film formation). By combining these functions into one integrated composition rather than separate products, the system achieves rapid fragrance release without proportionally increasing complexity
Solution Approach 2:
The composition uses composite material strategy by combining acid components (citric acid, fumaric acid), carbonate components (sodium bicarbonate, potassium carbonate), bulking constituents (sodium chloride, magnesium sulfate), and fragrance compounds into a single effervescing system. This composite approach enables multiple functions to be achieved simultaneously through the coordinated action of different components, achieving rapid fragrance release while managing composition complexity through functional integration

AI summary
The present composition relates to effervescing compositions used in the treatment of toilets, and in particular malodours which may emanate therefrom, as well as methods of making such compositions and methods of their use. The compositions may be in pulvurent form which may be a granular form, or may be in a solid form such as a tablet.
