Hydroxyacetophenone Protectant Blends for Stable Broad-Spectrum Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current natural and naturally-derived antimicrobial formulations are expensive, require high concentrations to be effective, have undesirable colors and odors, exhibit poor stability, and are not effective against a broad spectrum of microorganisms, often causing formulation thinning and limited usage due to being oils or extracts.
Innovation Solution
The use of hydroxyacetophenone in combination with 1,3-propanediol and mastic extract, or with vitamins B5, C, and E, provides a synergistic protectant system that inhibits microbial growth, including fungi, while being cost-effective, odorless, and stable, without causing formulation thinning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural and naturally-derived antimicrobial formulations are used, then antimicrobial activity is achieved, but cost increases and high concentrations are required
Solution Approach 1:
The patent combines hydroxyacetophenone with complementary antimicrobial agents (such as alcohols, phenols, or other natural antimicrobials) to create a synergistic formulation. This combination allows achieving broad-spectrum antimicrobial activity at lower individual concentrations compared to using hydroxyacetophenone alone, thereby reducing the total quantity of substance required while maintaining or enhancing antimicrobial reliability.
2Reliability
If natural and naturally-derived antimicrobial formulations are used, then antimicrobial activity is achieved, but undesirable colors and odors occur
Solution Approach 1:
The patent employs hydroxyacetophenone, which is specifically noted for having neutral or pleasant sensory properties, to address the color and odor issues. By strategically selecting and positioning this component within the formulation, the invention achieves antimicrobial activity while maintaining acceptable aesthetic qualities, thereby resolving the contradiction between functionality and sensory acceptance.
3Reliability
If natural and naturally-derived antimicrobial formulations are used, then antimicrobial activity is achieved, but stability in aqueous systems deteriorates
Solution Approach 1:
The patent creates a composite antimicrobial formulation by combining hydroxyacetophenone with complementary agents that have different solubility and stability characteristics. This composite approach leverages the strengths of each component, where hydroxyacetophenone provides antimicrobial activity and stability enhancement, while complementary agents contribute additional antimicrobial spectrum and synergistic effects, thereby achieving both stability and broad-spectrum activity in aqueous systems.
4Reliability
If natural and naturally-derived antimicrobial formulations are used, then antimicrobial activity is achieved, but effectiveness against broad spectrum of microorganisms is limited
Solution Approach 1:
The patent merges hydroxyacetophenone with complementary antimicrobial agents that have different spectral activities. This combination creates a synergistic effect where the formulation achieves broad-spectrum coverage including bacteria, fungi, and yeasts, thereby enhancing adaptability and versatility while maintaining antimicrobial reliability through the cooperative action of multiple components.
5Reliability
If natural and naturally-derived antimicrobial formulations are used, then antimicrobial activity is achieved, but formulation thinning occurs
Solution Approach 1:
The patent optimizes the concentration parameters and physical state of the antimicrobial formulation to prevent thinning. By carefully controlling the amount of hydroxyacetophenone and complementary agents used, and by adjusting formulation parameters such as viscosity modifiers or emulsifiers, the invention maintains antimicrobial activity while preventing unwanted thinning of the formulation, thereby resolving the contradiction between functionality and physical stability.
