Hypochlorite Lubricant Formulation for Candida Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current personal lubricants do not effectively address vaginal itching caused by Candida species, which is a common issue due to the fungus's resistance to anti-fungal drugs and its ability to form biofilms on medical devices, leading to difficult infections.
Innovation Solution
A lubricant composition incorporating hypochlorite, a silicone polymer, and an emulsifier, such as dimethicone and sodium phosphate, which provides antimicrobial properties to inhibit the growth of Candida species and other pathogens, thereby reducing itching and infection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-fungal drugs are used against Candida species, then the fungus's resistance to anti-fungal drugs makes treatment ineffective, but using stronger drugs increases harmful effects to healthy tissues
Solution Approach 1:
The patent changes the chemical parameter of the antimicrobial agent from conventional anti-fungal drugs to hypochlorite (sodium hypochlorite), which has different mechanisms of action. Hypochlorite works through oxidation rather than targeting specific fungal cell processes, thereby overcoming resistance while maintaining selectivity through controlled concentration and formulation pH
Solution Approach 2:
The patent employs hypochlorite, a strong oxidizing agent, to eliminate Candida species. The oxidizing action of hypochlorite disrupts fungal cell membranes and proteins, providing effective antimicrobial activity against resistant Candida strains without requiring the fungus to have specific drug targets that can be mutated for resistance
2Reliability
If lubricant formulations include antimicrobial agents to treat vaginal itching, then antimicrobial effectiveness improves, but cytotoxicity to healthy cells increases
Solution Approach 1:
The patent creates a composite lubricant formulation combining hypochlorite (antimicrobial agent), surfactants (for solubility and distribution), buffering agents (to maintain physiological pH), and lubricating base ingredients. This composite approach allows the antimicrobial component to function effectively while other components mitigate potential cytotoxicity through pH control and gentle formulation chemistry
Solution Approach 2:
The patent uses surfactants and buffering agents as intermediary substances that mediate between the hypochlorite and healthy tissues. These intermediaries control the release and activity of hypochlorite, ensuring it remains effective against pathogens while minimizing direct contact and damage to healthy epithelial cells
3Reliability
If hypochlorite is used to eliminate Candida species, then antimicrobial activity increases, but stability of the lubricant formulation decreases due to hypochlorite decomposition
Solution Approach 1:
The patent extracts hypochlorite from its conventional aqueous solution form and incorporates it into an anhydrous or low-water lubricant base. By removing water (the extraction step), the patent prevents hypochlorite decomposition through hydrolysis and maintains formulation stability while preserving antimicrobial activity
Solution Approach 2:
The patent changes the physical state parameter of the lubricant formulation from aqueous to anhydrous or semi-solid. This parameter change creates an environment where hypochlorite remains stable without water-mediated decomposition, while still maintaining effective concentration for antimicrobial activity against Candida species
Applied Scientific Principles
