Personal Cleansing Composition for Transdermal Absorption During Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal cleansing compositions that provide physiologically active ingredients topically are washed off during the cleansing process, requiring re-application and limiting their efficacy, especially after exercise.
Innovation Solution
A personal cleansing composition comprising carnosine, salicylic acid, and azone oil, which synergistically enhance skin permeability for transdermal absorption, allowing prolonged skin contact and improved ingredient penetration during bathing or showering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If topically applicable ingredients are applied as cream, ointment or tincture during cleansing, then the cleansing function is achieved, but the ingredients are dispersed and washed off requiring re-application
Solution Approach 1:
The patent changes the physical and chemical parameters of the composition by incorporating penetration enhancers (azone oil or laurocapram oil at 0.25-1%, salicylic acid at 0.5-2%) that modify the skin's permeability characteristics. This allows the physiologically active ingredients to penetrate the skin barrier effectively during the cleansing process, transforming the product from a surface-level cream to a transdermal delivery system that maintains efficacy without requiring re-application.
2Productivity
If ingredients are washed off during cleansing, then the cleansing process is complete, but the regeneration process is limited due to insufficient contact time
Solution Approach 1:
The patent introduces penetration enhancers (azone oil, laurocapram oil, and salicylic acid) as intermediary substances that facilitate the transfer of physiologically active ingredients through the skin barrier. These intermediaries enable the ingredients to penetrate deeper into the skin during the brief contact time of cleansing, effectively extending the duration of action and improving regeneration efficiency without requiring prolonged skin contact.
3Reliability
If penetration enhancers are added to improve transdermal absorption, then ingredient penetration is improved, but the formulation complexity increases
Solution Approach 1:
The patent creates a composite personal cleansing composition that integrates multiple functional components: surfactants for cleansing, penetration enhancers (azone oil or laurocapram oil combined with salicylic acid) for transdermal delivery, and physiologically active ingredients for regeneration. This composite formulation achieves enhanced transdermal absorption while maintaining a unified, commercially viable product structure that does not require separate application steps.
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 ensures effective absorption of active ingredients like carnosine and magnesium, providing skin benefits such as collagen formation, anti-oxidation, and muscle recovery without the need for re-application.
Implementation Method 1
the salicylic acid and azone oil act synergistically as a penetration enhancer that increases the skin's permeability for transdermal absorption of the physiologically active ingredients
Implementation Method 2
increases the skin's permeability for transdermal absorption of the physiologically active ingredients

AI summary
A personal cleansing composition having comprising a physiologically active amount of carnosine, wherein the personal cleansing composition is in the form of a shower gel, bubble bath, soap, or water-soluble delivery agent. The personal cleansing composition further comprises physiologically active ingredients including magnesium salt and caffeine in an amount of approximately 0.1% to 1.0% by weight of the total composition. The carnosine and magnesium salt form a carnosine-magnesium complex on activation with water, and wherein the personal cleansing composition further comprises transdermal absorption enhancers for the delivery of the physiologically active ingredients selected from the group consisting of salicylic acid in an amount of approximately 0.5% to 2.0% by weight of the total composition and azone oil in an amount of approximately 0.25% to 1% by weight of the total composition.
