Solution Overview
Problem
Formulating a hard surface cleaning composition that effectively cleans various surfaces while providing freshness benefits and high shine without compromising on surfactant and solvent levels, which are typically minimized due to environmental and regulatory concerns.
Innovation Solution
A cleaning composition comprising at least 85% water, 0.0015% alkoxylated phenol, and perfumes with ClogP greater than 1.0, along with a disposable dry cleaning wipe, to enhance solubility and stability, ensuring high perfume intensity and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high levels of surfactants are used to emulsify hydrophobic perfumes, then freshness benefits and scent intensity are improved, but cleaning performance and shine deteriorate due to residue left on surfaces
Solution Approach 1:
The patent uses a hydrophobe (isopropyl myristate or isopropyl palmitate) as an intermediary substance to solubilize hydrophobic perfume raw materials. This mediator allows the perfumes to be incorporated into the aqueous cleaning composition without requiring high levels of surfactants, thereby maintaining cleaning performance and shine while still delivering freshness benefits.
2Quantity of substance
If high levels of solvents are used to incorporate hydrophobic perfumes, then scent perception is improved, but environmental compliance and flashpoint regulations are compromised
Solution Approach 1:
The patent employs a hydrophobe as an intermediary to solubilize hydrophobic perfume raw materials, replacing the need for high levels of volatile organic compound solvents. This approach maintains scent perception while reducing VOC content to comply with environmental regulations and improve flashpoint safety.
3Manufacturing precision
If minimized surfactant levels are used to maintain shine, then cleaning residue is reduced, but the ability to emulsify and deliver hydrophobic perfumes deteriorates
Solution Approach 1:
The patent uses a hydrophobe as a mediator that enables the incorporation of hydrophobic perfumes into the aqueous formulation without requiring high surfactant concentrations. This allows the formulation to maintain low surfactant levels for optimal shine while still effectively delivering freshness through the incorporated perfumes.
4Quantity of substance
If hydrophobic perfumes are incorporated to provide freshness, then scent intensity is improved, but phase stability deteriorates without adequate emulsification
Solution Approach 1:
The patent employs a hydrophobe as an intermediary substance that solubilizes hydrophobic perfume raw materials, enabling high perfume concentrations to be incorporated while maintaining phase stability. The hydrophobe acts as a solubilizing agent that prevents phase separation and ensures stable formulation.
Solution Approach 2:
The patent changes the chemical parameters of the formulation by introducing a hydrophobe with specific solubilizing properties. This parameter change enables the system to accommodate high concentrations of hydrophobic perfumes while maintaining phase stability, as the hydrophobe modifies the overall solubility characteristics of the composition.
