Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray dishwashing detergents often cause skin and eye irritation due to product bounce back and overspray, leading to inefficient cleaning and potential inhalation risks, while requiring excessive product usage for effective cleaning of tough soils.
Innovation Solution
A sprayable cleaning composition comprising a surfactant system with an anionic surfactant and a co-surfactant, combined with a glycol ether solvent in a specific weight ratio, which minimizes irritation and overspray by breaking up glycol ether solvation spheres and improving physical stability, allowing for effective cleaning with reduced scrubbing effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spray dishwashing detergent is applied directly onto soiled dishware, then cleaning speed and efficiency are improved, but product bounce back and overspray cause skin and eye irritation
Solution Approach 1:
The patent changes the chemical composition parameters of the spray detergent by incorporating a specific glycol ether solvent (cellosolve or carbitol) in controlled amounts (1-10% and 1-5% respectively) alongside the surfactant system. This parameter change modifies the volatility and bonding characteristics of the formulation, reducing bounce back and overspray that cause irritation while maintaining cleaning speed and efficiency
Solution Approach 2:
The patent creates a composite cleaning formulation by combining multiple components: anionic surfactants (alkyl ethoxylated sulfates), co-surfactants (amine oxides), and specific glycol ether solvents (cellos_solve or carbitol). This composite material approach allows the formulation to achieve both rapid cleaning performance and reduced irritation through the synergistic effects of its components
2Quantity of substance
If conventional spray detergents are used for cleaning, then cleaning of light soils is achieved, but excessive product usage is required for tough soils like baked-, cooked- and burnt-on soils
Solution Approach 1:
The patent optimizes the concentration and type of surfactants and solvents in the formulation. By using specific ratios of anionic surfactants, co-surfactants, and glycol ether solvents, the formulation achieves enhanced grease removal and soil-loosening properties that reduce the amount of product needed while effectively handling tough soils
Solution Approach 2:
The patent incorporates bleach and bleach activators into the spray detergent formulation. These components provide oxidative cleaning power that accelerates the breakdown of tough soils such as baked-on, cooked-on, and burnt-on residues, reducing the quantity of product required for effective cleaning
3Productivity
If spray detergent is applied to clean dishware, then cleaning efficiency is improved, but product overspray leads to wasted product and potential inhalation risks
Solution Approach 1:
The patent modifies the volatility parameters of the spray detergent by incorporating glycol ether solvents with specific boiling points and vapor pressure characteristics. This parameter change reduces the formation of fine aerosol particles that cause overspray and inhalation risks, while maintaining the sprayability and cleaning efficiency of the formulation
