Ketoconazole Shampoo pH Control for Skin Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current topical treatments for mammals, especially humans and dogs, face challenges in effectively addressing fungal and bacterial infections on the skin without causing harm, particularly in environments lacking access to clean water where microbial skin diseases are prevalent.
Innovation Solution
A composition comprising water, hydrochloric acid, ketoconazole as a fungicide, and chloroxylenol as an anti-microbial, along with other ingredients like methyl glucose dioleate and cocamidopropyl betaine, is formulated into a shampoo that can be used as a topical treatment in various forms, including a cream, lotion, or bodywash, to address fungal and bacterial infections while preventing dandruff and treating conditions like seborrhea and ringworm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strong anti-fungal and antibacterial agents are used to eliminate fungus and bacteria on the skin, then the effectiveness of treating microbial skin diseases is improved, but the harm to the skin increases
Solution Approach 1:
The patent adjusts the pH level of the shampoo composition to a specific range (acidic to neutral, approximately pH 4-7) to optimize the effectiveness of anti-fungal and antibacterial agents while minimizing skin irritation. This parameter change allows the active ingredients to work more effectively at lower concentrations, reducing harm to the skin while maintaining treatment reliability.
Solution Approach 2:
The patent combines multiple gentle surfactants (ammonium laureth sulfate, ammonium methyl oleate, ammonium acrylamide copolymer) with anti-fungal and antibacterial agents in a composite shampoo formulation. This composite approach provides synergistic effects where the gentle surfactants clean the skin without stripping natural oils, while the anti-microbial agents effectively treat infections, achieving both high reliability and reduced harm.
2Productivity
If conventional shampoos are used to clean skin and hair, then the cleaning effectiveness is improved, but the ability to prevent and treat fungal and bacterial infections deteriorates
Solution Approach 1:
The patent merges conventional cleaning agents (ammonium laureth sulfate, ammonium methyl oleate) with anti-fungal and antibacterial ingredients (ketoconazole, chloroxylenol, zinc ribbons) into a single shampoo composition. This combination allows the shampoo to perform both cleaning and infection treatment functions simultaneously, achieving high productivity in cleaning while maintaining high reliability in preventing and treating microbial skin diseases.
Solution Approach 2:
The shampoo composition is designed to perform multiple functions: cleaning the skin and hair, preventing fungal infections, preventing bacterial infections, and treating existing infections. This multi-functionality allows a single product to address both cleaning effectiveness and infection treatment reliability, eliminating the need for separate products for each function.
3Reliability
If harsh chemicals are used to eliminate dandruff and treat skin conditions, then the treatment effectiveness is improved, but the skin irritation increases
Solution Approach 1:
The patent formulates the shampoo with a controlled pH level (acidic to neutral, approximately pH 4-7) and uses gentle surfactants that maintain the skin's natural moisture barrier. This parameter control allows effective treatment of dandruff and skin conditions through anti-fungal and antibacterial agents while minimizing skin irritation by avoiding harsh chemicals and excessive pH extremes.
Solution Approach 2:
The patent employs zinc ribbons and other gentle anti-microbial agents that provide effective treatment without the need for harsh, long-lasting chemicals. These ingredients offer sufficient treatment effectiveness for dandruff and skin conditions while being mild on the skin, reducing irritation and allowing for safe, repeated use without cumulative harm.
