Benzethonium Chloride Topical Composition for Antimicrobial and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skin care products lack a broad-spectrum, self-preserving, antimicrobial composition that effectively prevents microbial contamination after hair removal while also soothing and moisturizing the skin.
Innovation Solution
A topical composition combining benzethonium chloride as a quaternary ammonium compound with menthyl lactate in a cationic carrier, optionally including phenoxyethanol and chlorhexidine digluconate, to provide antimicrobial activity, cooling, and moisturizing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional preservatives and single-use products are used to prevent microbial contamination, then microbial risk is reduced, but product complexity and usage convenience deteriorate
Solution Approach 1:
The patent combines multiple antimicrobial agents (benzethonium chloride, phenoxyethanol, chlorhexidine digluconate) with skin care ingredients (menthyl lactate, aloe vera, vitamin E) to create a composite formulation that provides both broad-spectrum antimicrobial protection and skin care benefits in a single product, eliminating the need for separate preservatives and single-use products
Solution Approach 2:
The composition serves multiple functions simultaneously: it acts as an antimicrobial agent, preservative, skin cooler, moisturizer, and conditioner all in one formulation, allowing it to replace multiple separate products and simplify the regimen while maintaining reliable microbial protection
2Reliability
If broad-spectrum antimicrobial agents are used to kill resistant bacteria and fungi, then microbial efficacy is improved, but skin irritation and harmful effects worsen
Solution Approach 1:
The patent uses a combination of three different antimicrobial agents at optimized concentrations (benzethonium chloride 0.1-1.0%, phenoxyethanol 0.1-2.0%, chlorhexidine digluconate 0.01-0.5%) to achieve broad-spectrum coverage while maintaining skin compatibility, and includes skin-soothing ingredients like aloe vera and vitamin E to counteract potential irritation
Solution Approach 2:
The patent converts the potential harm of strong antimicrobial agents by combining them with skin-protective and soothing ingredients (aloe vera, vitamin E, menthyl lactate) that neutralize irritation effects while enhancing the overall benefit of the formulation through synergistic action
3Reliability
If multiple separate treatments are used for different skin conditions, then treatment effectiveness is improved, but ease of operation and time consumption worsen
Solution Approach 1:
The single composition addresses multiple skin conditions and needs simultaneously: antimicrobial protection, skin cooling, moisturizing, and conditioning, allowing users to replace multiple separate treatments with one versatile product that maintains effectiveness across different applications
Solution Approach 2:
The patent merges multiple functional ingredients and treatments into one unified formulation, combining antimicrobial agents, moisturizers, coolants, and conditioners that work synergistically to provide comprehensive skin care in a single application step
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 kills a broad spectrum of bacteria, fungi, and yeasts, including resistant strains, while cooling and soothing the skin, making it suitable for first aid treatments and skin sanitization, particularly after hair removal.
Implementation Method 1
The compositions kill a broad spectrum of gram-negative and gram-positive bacteria, fungus and yeasts
Implementation Method 2
menthyl lactate in a cationic carrier... additionally cool, soothe and moisturize the skin
Implementation Method 3
a phenoxyethanol preservative... to assist in enhancing the activity
Implementation Method 4
chlorhexidine digluconate antibacterial agent may be used to assist in enhancing the activity

AI summary
A stable, self-preserving, antimicrobial, composition suitable for the treatment of a variety of dermal as well as subcutaneous conditions. The compositions include as an active ingredient a quaternary ammonium compound, preferably benzethonium chloride, potentiated and synergized with menthyl lactate cooling agent in a cationic carrier. Optionally, a phenoxyethanol preservative and chlorhexidine digluconate antibacterial agent may be used to assist in enhancing the activity. The compositions kill a broad spectrum of gram-negative and gram-positive bacteria, fungus and yeasts. The compositions are used as first aid skin treatments and as skin sanitizers to help prevent bacterial contamination of minor cuts, scrapes and burns. The compositions are particularly useful when applied to the skin after hair removal in that they additionally cool, soothe and moisturize the skin. The compositions may also serve as a base vehicle in which additional skin care ingredients may be added to provide additional functionality to the compositions.
