Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lactams used in antimicrobial compositions have relatively low solubility, especially in aqueous solutions, limiting their effectiveness and application.
Innovation Solution
Combining lactams with an alcohol, such as ethanol or methanol, to enhance solubility, allowing for the creation of compositions that are miscible with water and suitable for various applications including personal care, pharmaceutical, and industrial uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lactams are used in antimicrobial compositions, then antimicrobial activity is achieved, but solubility in aqueous solutions is low
Solution Approach 1:
The patent introduces alcohols as intermediary substances to mediate between the lactam (which has poor water solubility) and the aqueous environment. The alcohol molecules interact with both the lactam and water, forming a bridge that enables the lactam to dissolve in aqueous solutions while maintaining its antimicrobial activity. This is achieved by the alcohol's dual affinity - its hydrophobic portion interacts with the lactam while its hydrophilic hydroxyl group interacts with water.
2Reliability
If lactam concentration is increased to improve antimicrobial effectiveness, then activity increases, but solubility limitations are reached
Solution Approach 1:
The patent changes the chemical composition parameters of the solution by adding alcohols, which fundamentally alters the solubility parameters of the system. This allows the lactam concentration to be increased beyond the original solubility limit in pure water, thereby achieving higher antimicrobial effectiveness without precipitation or phase separation.
3Object-affected harmful factors
If pure aqueous compositions are used, then biocompatibility is good, but lactam solubility is poor
Solution Approach 1:
The patent creates a composite liquid composition containing three main components: water (providing biocompatibility), alcohol (providing solubility enhancement), and lactam (providing antimicrobial activity). This composite system combines the beneficial properties of each component while mitigating their individual limitations, resulting in a composition that is both biocompatible and has sufficient lactam solubility for effective antimicrobial action.
