Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concentrated liquid detergent premixes face challenges in forming a stable, isotropic composition with viscosity comparable to conventional liquid detergents upon dilution in water, as they typically contain low water content, making it difficult to incorporate ingredients like soil release polymers and enzymes effectively.
Innovation Solution
A composition comprising 30 to 90% wt. anionic surfactant with an ammoniacal counterion and an alkoxylated polyol polyester with at least three alkoxylates and C8 to C40 fatty acid esters, which upon dilution in water, forms a liquid detergent with viscosity comparable to conventional detergents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a liquid detergent contains significant amount of water to solubilize ingredients, then ingredient stability and homogeneity are improved, but product volume increases requiring substantial packaging materials
Solution Approach 1:
The patent changes the physical state and concentration parameters of the detergent composition by providing a highly concentrated liquid premix with 10-50% w/w detersive actives and 0-40% w/w water. This parameter change allows the product to maintain ingredient stability through proper formulation while significantly reducing product volume and packaging requirements compared to conventional diluted liquid detergents.
2Volume of moving object
If a concentrated premix contains low water content to reduce packaging, then packaging material consumption is reduced, but stability and homogeneity of ingredients become difficult to achieve
Solution Approach 1:
The patent employs composite material formulation by combining multiple ingredients in a specific concentration range: 10-50% w/w detersive actives, 0-40% w/w water, 1-30% w/w solvents, and various additives. This composite approach creates a stable concentrated premix where each component serves a specific function, maintaining homogeneity and stability despite reduced water content through synergistic interactions between ingredients.
3Volume of moving object
If a dilutable product contains higher amount of detersive actives to reduce packaging, then packaging material consumption is reduced, but viscosity control becomes challenging
Solution Approach 1:
The patent controls viscosity by adjusting concentration parameters of key ingredients, particularly solvents (1-30% w/w) and water (0-40% w/w), while maintaining high detersive active content (10-50% w/w). This parameter optimization ensures the concentrated premix has appropriate viscosity for ease of use, pouring, and dissolution, even with reduced water content and high active ingredient concentration.
4Reliability
If conventional liquid detergent formulation is used to ensure cleaning benefits, then cleaning performance is improved, but water content increases making product bulky
Solution Approach 1:
The patent achieves concentrated cleaning performance by changing the concentration parameters to 10-50% w/w detersive actives and 0-40% w/w water, compared to conventional diluted formulations. This parameter change maintains reliable cleaning performance through inclusion of essential ingredients (anionic/non-ionic surfactants, enzymes, bleaching agents, soil release polymers) in optimized concentrations while reducing product volume by 50-80% compared to conventional liquid detergents.
