Dentifrice Formulations with Hypochlorous Acid for Oral Care
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oral care compositions are inadequate in effectively addressing poor oral health issues such as halitosis, tooth decay, gum disease, and their associated general health problems like heart disease and preterm birth, as they fail to provide comprehensive microbial control and tooth whitening.
Innovation Solution
An oral care composition combining hypochlorite, sodium magnesium silicate, hydrated silica, and a surfactant like sodium coco sulfate, along with a phosphate buffer, which is formulated as a toothpaste or oral rinse to inhibit microbial growth, reduce plaque, and whiten teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional oral care compositions are used, then basic cleaning function is provided, but microbial control and tooth whitening effectiveness are insufficient
Solution Approach 1:
The patent combines multiple active ingredients (hypochlorite, acids, abrasives, surfactants, buffers) into a single integrated oral care composition that simultaneously provides microbial control, cleaning, and whitening functions, resolving the contradiction by merging multiple functions into one formulation
Solution Approach 2:
The oral care composition is designed to perform multiple functions including antimicrobial action, plaque removal, tooth whitening, and cleaning in a single product, thereby improving reliability across multiple oral health parameters without requiring multiple separate products
2Reliability
If hypochlorite is added to oral care composition, then microbial growth inhibition is improved, but formulation stability becomes challenging
Solution Approach 1:
The patent introduces buffers as intermediary substances that mediate between hypochlorite and other formulation components, controlling pH levels to maintain hypochlorite stability and prevent unwanted reactions, thereby resolving the stability challenge
Solution Approach 2:
The patent carefully controls pH parameters through buffer systems to optimize hypochlorite stability and effectiveness, demonstrating how parameter adjustment resolves the contradiction between microbial inhibition and formulation stability
3Reliability
If multiple active ingredients are combined for comprehensive oral care, then overall oral health improvement is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent performs preliminary formulation work by pre-mixing and stabilizing the multi-ingredient composition during manufacturing, incorporating all necessary components (hypochlorite, acids, abrasives, surfactants, buffers) in predetermined ratios and sequences to simplify the overall manufacturing process while maintaining comprehensive effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively cleanses and whitens teeth, inhibits microbial growth, reduces plaque and gingivitis, and promotes overall oral health, thereby addressing the broader health implications of poor oral hygiene.
Implementation Method 1
hypochlorous acid, or salts or acids or derivatives thereof... killing or inhibiting the growth or proliferation of microbes
Implementation Method 2
