Effervescent Peroxymonosulfate Tablet for Rapid Mouthrinse Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current denture cleaning tablets and mouthrinse products face challenges with slow dissolution and stability issues, particularly with potassium peroxymonosulfate, which is an effective oxidizing agent but has limited stability in aqueous solutions and toothpaste ingredients, and there is a need for a fast-dissolving, effective tooth whitening agent in a solid form suitable for mouthrinse applications.
Innovation Solution
A solid composition comprising 7.5% to 15% potassium peroxymonosulfate, a buffering agent, crosslinked polyvinylpyrrolidone as a disintegrating agent, and an effervescent couple, which completely dissolves in water within 1 minute without visible particulates, packaged in a moisture-free environment to maintain stability, and can be used as a whitening mouthrinse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If potassium peroxymonosulfate is used as a whitening agent in solid form, then tooth whitening effect is achieved, but dissolution time is long and particulates remain
Solution Approach 1:
The solid composition is segmented into multiple functional components: effervescent couple (acid + carbonate/base), disintegrating agents (crosslinked polyvinylpyrrolidone, starch), and binding agents. This segmentation allows each component to perform its specific function - the effervescent couple generates gas bubbles for rapid disintegration, while the disintegrating agents break down the tablet structure, achieving complete dissolution within 1 minute without visible particulates.
Solution Approach 2:
The patent optimizes the concentration parameters of key ingredients: effervescent acid (15-50% by weight), effervescent carbonate/base (15-50% by weight), and disintegrating agents (1-10% by weight). By adjusting these parameters, the dissolution rate is dramatically improved while maintaining the whitening efficacy of potassium peroxymonosulfate (7.5-15% by weight).
2Ease of operation
If potassium peroxymonosulfate is stored in aqueous solution, then it is ready to use, but stability is poor and decomposition occurs
Solution Approach 1:
The patent prepares the composition in solid tablet form with all ingredients pre-measured and pre-mixed, including the effervescent couple and disintegrating agents. This preliminary preparation allows the product to be stored stably in dry condition and only activates the dissolution process when the consumer adds water at the point of use, eliminating stability issues during storage while maintaining ease of operation.
Solution Approach 2:
The effervescent system creates a temporary inert environment through rapid gas evolution upon contact with water, which helps protect the potassium peroxymonosulfate from premature decomposition during the dissolution process. The carbon dioxide generated forms bubbles that can help isolate the peroxymonosulfate from direct contact with atmospheric factors during the brief dissolution period.
3Reliability
If tablet size is increased for effective whitening, then sufficient active ingredient is provided, but dissolution becomes slower and more particulates remain
Solution Approach 1:
The patent creates a composite tablet structure incorporating multiple materials with complementary functions: effervescent acid and carbonate/base for gas generation, crosslinked polyvinylpyrrolidone and starch for rapid disintegration, binding agents for structural integrity, and potassium peroxymonosulfate for whitening. This composite approach allows the tablet to maintain adequate size for effective whitening while achieving rapid dissolution through the synergistic action of its components.
Solution Approach 2:
The effervescent reaction generates vigorous bubbling and mechanical agitation within the tablet matrix, creating internal vibrations and movements that accelerate the breakdown of the tablet structure. This self-generated mechanical energy promotes rapid disintegration and dissolution, allowing larger tablets to dissolve completely within 1 minute without leaving visible particulates.
4Speed
If effervescent ingredients are added to accelerate dissolution, then dissolution speed improves, but stability during storage deteriorates
Solution Approach 1:
The effervescent system is segmented into two separate inactive components during storage: effervescent acid and effervescent carbonate/base. These components remain stable individually in the dry tablet formulation and only react with each other upon contact with water during use. This segmentation allows the inclusion of effervescent ingredients for rapid dissolution without compromising storage stability, as the reactive components are physically separated until activation.
