Multi-Ion Storage Stabilization for Aqueous Home Care
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage stabilization agents for aqueous home care formulations often rely on conventional antimicrobials like isothiazolinones, which pose environmental and health risks, and are ineffective in high pH conditions, leading to microbial growth and quality degradation during storage.
Innovation Solution
A storage stabilization agent comprising at least two different water-soluble or water-dispersible ion sources, including bismuth ions, lithium ions, magnesium ions, and alkali ions, selected from alkali carbonate and hydromagnesite, which effectively stabilizes aqueous home care formulations against microbial growth without the need for additional antimicrobials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antimicrobials like isothiazolinones are used for storage stabilization, then microbial growth is inhibited, but environmental and health risks increase and effectiveness is lost in high pH conditions
Solution Approach 1:
The invention changes the chemical parameters by using multiple ion sources (bismuth, lithium, magnesium, and alkali ions) instead of conventional antimicrobials. This parameter change enables effective storage stabilization in high pH conditions without the harmful effects of isothiazolinones, directly resolving the contradiction between effectiveness and safety
Solution Approach 2:
The invention extracts and eliminates harmful substances (isothiazolinones and other conventional antimicrobials) from the formulation while maintaining storage stabilization functionality through alternative ion-based mechanisms, thus removing the harmful factors while preserving the desired effect
2Reliability
If conventional antimicrobials are used, then microbial growth is controlled, but the formulation requires additional harmful substances and becomes less environmentally friendly
Solution Approach 1:
The invention removes harmful substances from the formulation by replacing conventional antimicrobials with a multi-ion system comprising bismuth, lithium, magnesium, and alkali ions, thereby achieving microbial control without introducing harmful factors
Solution Approach 2:
The invention changes the compositional parameters by using naturally occurring ions at controlled concentrations (e.g., bismuth ions at 1-100 ppm, lithium ions at 10-500 ppm) to achieve preservation through non-harmful mechanisms, eliminating the need for harmful antimicrobial substances
3Stability of the object's composition
If storage stabilizers are used to prevent quality degradation, then formulation stability is improved, but the complexity of the formulation increases
Solution Approach 1:
The multi-ion system serves multiple functions simultaneously: pH buffering, microbial inhibition, and quality stabilization, thereby improving formulation stability without proportionally increasing complexity. The ions work synergistically to achieve multiple stabilization goals with a unified approach
