Sorbic and Hydroxamic Acid Combination for Dandruff Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic deodorants and antimicrobial substances often impair the skin's natural flora, are not effective in selectively targeting odor-causing microorganisms, and can have adverse effects due to the combination of astringents and antimicrobials, leading to incomplete deodorization and potential skin damage.
Innovation Solution
A combination of sorbic acid and physiologically harmless hydroxamic acids, such as octanohydroxamic acid, is used to combat or prevent dandruff and other skin issues by effectively targeting gram-positive and gram-negative bacteria, mycobionts, and viruses without disrupting the skin's natural flora.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If astringents and antimicrobial substances are combined in cosmetic deodorants, then deodorization effectiveness is improved, but skin irritation and adverse effects increase
Solution Approach 1:
The patent uses naturally occurring substances (essential oils, plant extracts, vitamins) as intermediary agents that provide antimicrobial and deodorizing effects without the harsh side effects of traditional astringents and synthetic antimicrobials. These natural intermediaries mediate between the need for effective deodorization and skin compatibility, resolving the contradiction by replacing harmful substances with beneficial natural alternatives.
Solution Approach 2:
The invention changes the chemical parameters of active ingredients from synthetic astringents and antimicrobials to natural substances with different chemical compositions. This parameter change includes using essential oils, plant extracts, and vitamins that have different molecular structures and mechanisms of action, thereby achieving deodorization with reduced skin irritation.
2Reliability
If conventional antimicrobial substances are used, then pathogen growth is inhibited, but the skin's natural flora is disrupted
Solution Approach 1:
The patent applies substances with selective action that target pathogenic microorganisms while leaving beneficial skin flora unaffected. The active ingredients (essential oils, plant extracts, vitamins) exhibit local quality in their antimicrobial activity, selectively inhibiting pathogens like Staphylococcus aureus and Pityrosporum ovale while maintaining the balance of natural skin flora through their specific mechanisms of action.
3Reliability
If traditional deodorant formulations are used, then odor control is achieved, but product stability and compatibility with other ingredients are compromised
Solution Approach 1:
The patent employs composite formulations combining multiple natural substances (essential oils, plant extracts, vitamins, and other cosmetic ingredients) that work synergistically. This composite approach enhances formulation stability and compatibility by using naturally stable components that do not react adversely with each other, unlike traditional synthetic deodorant ingredients that may interact negatively.
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 active ingredient combination prevents the growth of pathogens like Staphylococcus aureus and Pityrosporum ovale, effectively addressing dandruff and impure skin conditions while maintaining the skin's natural balance, and is suitable for use in cosmetic and dermatological preparations.
Implementation Method 1
an active ingredient combination comprising sorbic acid and one or more physiologically harmless hydroxamic acids is used to combat or prevent dandruff
