Solution Overview
Problem
Current degreasing compositions, such as WD-40, are environmentally harmful and toxic, and existing alternatives lack effectiveness in treating burnt greases on mechanical parts, especially when used as aerosols or require rinsing.
Innovation Solution
A composition comprising alkanes of the formula CnH2n+2, where n≤12, combined with oxoesters, providing a bio-based, non-toxic, and biodegradable solution for degreasing, cleaning, protecting, and lubricating surfaces, with improved volatility and skin compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petrochemical-based degreasing compositions (e.g., WD-40) are used, then effective degreasing performance is achieved, but environmental harm and skin toxicity increase
Solution Approach 1:
The patent changes the chemical composition parameters by replacing petrochemical hydrocarbons with bio-based alkanes (CnH2n+2, n≤12) and using oxoesters as alternatives to traditional petroleum-based oils. This parameter change maintains the degreasing functionality while eliminating the harmful petrochemical components, achieving both effective performance and environmental compatibility
Solution Approach 2:
The invention creates a composite degreasing composition combining bio-based alkanes with oxoesters in specific proportions (alkane: 40-95% v/v, oxoester: 5-60% v/v). This composite formulation synergistically combines the volatility and cleaning properties of alkanes with the lubricating and protective properties of oxoesters, achieving effective degreasing without petrochemical harm
2Reliability
If levulinic acid ester compositions are used for degreasing metal surfaces, then some cleaning effect is achieved, but volatility is poor requiring complex aerosol formulation and rinsing
Solution Approach 1:
The patent optimizes the volatility parameter by selecting alkanes with specific carbon chain lengths (n≤12), which provide appropriate vapor pressure for aerosol formation without requiring complex propellant systems. The bio-based alkane composition naturally achieves good volatility, eliminating the need for complex aerosol formulation and post-application rinsing
Solution Approach 2:
The invention extracts and eliminates the need for rinsing by using a composition that naturally degrades and evaporates completely. The bio-based alkane and oxoester combination provides sufficient cleaning power in a single application, removing the harmful residue that would otherwise require rinsing, thus simplifying the overall usage process
3Device complexity
If compositions with good volatility are developed, then aerosol formulation is simplified, but effectiveness in treating burnt greases may be reduced
Solution Approach 1:
The patent creates a composite system where bio-based alkanes provide volatility for simplified aerosol formulation while oxoesters provide the chemical activity needed to treat burnt greases. The synergistic combination ensures that both volatility and effectiveness are achieved simultaneously, with the oxoester component specifically targeting burnt grease removal while the alkane component ensures proper vaporization
Solution Approach 2:
The composition achieves multi-functionality by simultaneously providing: (1) good volatility for aerosol delivery, (2) cleaning action on burnt greases, (3) protective properties, and (4) lubricating effects. The bio-based alkane and oxoester combination performs multiple functions that were previously achieved by separate substances, eliminating the trade-off between volatility and effectiveness
