Innovation Solution
A flowable detergent preparation comprising 0.5 to 10 wt.% of a polyalkoxylated amine, 0.1 to 5 wt.% of aminocarboxylic acids or their salts, 12 to 40 wt.% of anionic surfactant, 12 to 40 wt.% of non-ionic surfactant, and less than 20 wt.% of water, which is packaged in water-soluble portion sachets made from renewable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the concentration of active substances is increased to reduce water content and improve cleaning performance, then cleaning performance and sustainability are improved, but storage stability and compatibility deteriorate
Solution Approach 1:
The patent changes the chemical parameters of the detergent formulation by introducing specific polyalkoxylated amines with controlled molecular weights (600-10000 g/mol) and specific structures (block or random) to stabilize the high-concentration formulation. This allows the detergent to maintain storage stability while achieving the desired high concentration of active substances for improved cleaning performance and reduced water content.
Solution Approach 2:
The patent creates a composite detergent system combining polyalkoxylated amines with specific builders (aminocarboxylic acids and salts) and surfactants in defined proportions. This composite formulation synergistically stabilizes the high-concentration active substances while maintaining compatibility and storage stability, resolving the contradiction between concentration and stability.
2Volume of stationary object
If the concentration of active substances is increased to reduce packaging volume and improve sustainability, then transport volumes and packaging materials are reduced, but cleaning performance and compatibility deteriorate
Solution Approach 1:
The patent optimizes the concentration parameters of active substances within specific ranges (polyalkoxylated amine: 0.5-10 wt.%, builders: 0.1-5 wt.%, anionic surfactant: 12-40 wt.%, non-ionic surfactant: 12-40 wt.%, water: <20 wt.%) to achieve high concentration that reduces packaging volume while maintaining reliable cleaning performance through the stabilized formulation.
Solution Approach 2:
The patent develops a composite detergent composition with specifically selected and proportioned ingredients that work synergistically to maintain cleaning performance at high concentrations. The combination of polyalkoxylated amines, builders, and surfactants in defined ratios ensures that the reduced packaging volume does not compromise cleaning effectiveness.
3Object-affected harmful factors
If biodegradable substances are used to meet environmental requirements, then sustainability is improved, but the number of available active substances is limited
Solution Approach 1:
The patent selects and optimizes the molecular weight parameters of polyalkoxylated amines (600-10000 g/mol) and the structure parameters (block or random) to achieve biodegradability while maintaining washing performance. This parameter optimization expands the range of available biodegradable active substances that can be effectively used in detergent formulations.
Solution Approach 2:
The patent creates a composite formulation combining biodegradable polyalkoxylated amines with biodegradable builders and surfactants in specific proportions. This composite approach maintains environmental compatibility while providing sufficient active substance variety and effectiveness for reliable cleaning performance.
