Solution Overview
Problem
Botanical disinfection compositions face challenges with poor chemical stability and reduced disinfection effect due to the addition of auxiliary materials, which can weaken the sterilization effect and shorten the product's validity period.
Innovation Solution
A disinfection composition comprising disinfection essential oils, polyethylene glycol hydrogenated castor oil, phytic acid, citric acid, C2-C3 monohydric alcohol, and water in specific ratios, along with azelaic acid and cosolvents, to enhance chemical stability and disinfection efficacy, while minimizing the use of auxiliary materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If auxiliary materials (Tween 80, ethanol, propylene glycol, disodium EDTA) are added to form an emulsion to improve physical stability, then physical stability is improved, but chemical stability deteriorates and active ingredient content decreases during storage
Solution Approach 1:
The patent changes the chemical composition parameters by replacing traditional emulsion-forming auxiliary materials (Tween 80, disodium EDTA) with a novel combination of polyethylene glycol hydrogenated castor oil as the sole emulsifier, phytic acid, and citric acid. This parameter change resolves the contradiction by achieving both physical stability (through effective emulsification) and chemical stability (by eliminating ingredients that cause active ingredient degradation).
Solution Approach 2:
The patent extracts and removes harmful auxiliary materials from the formulation. Specifically, it eliminates Tween 80 and disodium EDTA which were causing chemical instability and active ingredient loss, retaining only the essential emulsifying components needed for physical stability while improving overall chemical stability.
2Stability of the object's composition
If auxiliary materials are added to improve stability, then stability is improved, but disinfection effect decreases
Solution Approach 1:
The patent optimizes the concentration parameters of auxiliary materials, reducing them to minimal effective amounts. Polyethylene glycol hydrogenated castor oil is used at 3-8 parts, phytic acid at 0.05-0.5 parts, and citric acid at 0.05-0.5 parts per 2.2-4.8 parts of essential oil. This minimalistic approach maintains stability while preserving the dominant disinfection effect of the essential oils.
Solution Approach 2:
The patent applies partial action by using the smallest necessary amounts of auxiliary materials to achieve stability. Rather than using large quantities of emulsifiers and stabilizers, it employs minimal concentrations that are sufficient for stability but do not interfere with the disinfection efficacy of the essential oil active ingredients.
3Stability of the object's composition
If emulsion is used to improve physical stability, then physical stability is improved, but product validity period shortens due to reduced active ingredient content
Solution Approach 1:
The patent removes ingredients that cause active ingredient degradation during storage. By eliminating Tween 80 and disodium EDTA from the formulation, it prevents the chemical reactions that lead to active ingredient loss, thereby extending the product's validity period while maintaining physical stability through the alternative emulsifier system.
Solution Approach 2:
The patent uses phytic acid and citric acid as natural, stable, and inexpensive stabilizing agents that provide long-term protection without degrading the active ingredients. These materials offer sustained stability throughout the product's shelf life, effectively extending the validity period.
