Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleansing compositions face challenges with the use of medium chain fatty acids, which are costly and have an unpleasant odor, and aromatic carboxylic acids, which affect the viscosity of the composition.
Innovation Solution
Incorporating ammonium salts, such as ammonium chloride, in combination with aromatic carboxylic acids like benzoic acid, to enhance antimicrobial efficacy and maintain viscosity in cleansing compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medium chain fatty acids (e.g., hexanoic acid, octanoic acid) are used for antimicrobial effect, then good antimicrobial efficacy is achieved, but cost increases and peculiar odor is generated
Solution Approach 1:
The patent changes the chemical parameter by substituting medium chain fatty acids with aromatic carboxylic acids (benzoic acid, cinnamic acid, salicylic acid) that have different molecular structures and properties. This parameter change eliminates the peculiar odor associated with medium chain fatty acids while maintaining antimicrobial efficacy through the synergistic combination with ammonium salts
Solution Approach 2:
The patent introduces ammonium salts as an intermediary component that enhances the antimicrobial efficacy of aromatic carboxylic acids. This intermediary substance creates a synergistic effect, allowing the use of cheaper, odorless aromatic acids to achieve the same or better antimicrobial performance as expensive medium chain fatty acids
2Ease of manufacture
If aromatic carboxylic acids (e.g., benzoic acid, cinnamic acid) are used in cleansing compositions, then cost is reduced and odor issues are avoided, but viscosity is affected
Solution Approach 1:
Ammonium salts serve as a viscosity-modifying intermediary that compensates for the viscosity-reducing effect of aromatic carboxylic acids. By adding ammonium salts, the composition maintains appropriate viscosity levels while benefiting from the cost advantages and odor-free properties of aromatic acids
Solution Approach 2:
The patent creates a composite system combining aromatic carboxylic acids with ammonium salts, where the two components work together to achieve both cost-effectiveness and proper rheological properties. This composite approach allows the formulation to overcome the limitations of individual components
3Ease of manufacture
If aromatic carboxylic acids are used without ammonium salts, then cost is reduced, but antimicrobial efficacy is insufficient and duration is prolonged
Solution Approach 1:
Ammonium salts act as a efficacy-enhancing intermediary that amplifies the antimicrobial action of aromatic carboxylic acids. This intermediary creates a synergistic relationship where the combination achieves superior antimicrobial efficacy compared to aromatic acids alone, enabling rapid microbial reduction within 10-30 seconds
Solution Approach 2:
The patent changes the kinetic parameter by introducing ammonium salts that accelerate the antimicrobial action. This parameter change reduces the contact time required for effective microbial reduction from several minutes to just 10-30 seconds, while maintaining cost-effectiveness through the use of aromatic carboxylic acids
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 combination of ammonium salts and aromatic carboxylic acids provides a synergistic antimicrobial effect, achieving rapid microbial reduction within 10 to 30 seconds, while maintaining the desired viscosity of the composition.
Implementation Method 1
addition of ammonium salts e.g. ammonium chloride, significantly improves the antimicrobial efficacy of aromatic carboxylic acids e.g. benzoic acid
Implementation Method 2
addition of ammonium salts also provided required viscosity to the cleansing composition despite the composition contained aromatic carboxylic acids e.g. benzoic acid
