Problem
Conventional detergents used in warewashing and laundering industries rely on phosphates for effective cleaning, but recent regulations have prompted a need for environmentally friendly alternatives that can replace phosphorous-containing compounds while maintaining detergency and anti-redeposition properties.
Innovation Solution
A cleaning composition and method utilizing a poly sugar-based protein-removing/anti-redeposition agent, which includes alkalinity sources and optionally surfactants, to effectively remove protein soils and prevent redeposition on surfaces, while being substantially free of phosphorus-containing compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phosphates are used in detergents, then detergency and anti-redeposition properties are improved, but environmental friendliness deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters by replacing phosphates with poly sugar-based agents, maintaining cleaning effectiveness while improving environmental compatibility. The poly sugar composition includes specific components like carboxymethyl inulin and other polysaccharides that provide similar functional properties without phosphorus content.
Solution Approach 2:
The invention extracts and removes phosphorus-containing compounds from the detergent formulation, eliminating the harmful component while retaining the essential detergency and anti-redeposition functions through alternative poly sugar-based agents.
2Reliability
If phosphates are used in detergents, then anti-redeposition properties are improved, but environmental friendliness deteriorates
Solution Approach 1:
The patent modifies the chemical parameters by substituting phosphate-based anti-redeposition agents with poly sugar-based alternatives. The poly sugar composition, containing components like carboxymethyl inulin and other polysaccharides, provides equivalent soil suspension and anti-redeposition performance without phosphorus content.
Solution Approach 2:
The invention removes phosphorus-containing compounds from the formulation while extracting and incorporating poly sugar-based agents that provide the necessary anti-redeposition functionality through natural polymer structures.
3Object-affected harmful factors
If poly sugar-based agents are used to replace phosphates, then environmental friendliness is improved, but cleaning effectiveness may deteriorate
Solution Approach 1:
The patent employs a composite poly sugar-based formulation containing multiple components including carboxymethyl inulin, other inulin derivatives, and additional polysaccharides. This composite approach combines the strengths of different natural polymers to achieve comprehensive cleaning effectiveness comparable to phosphate-based detergents.
Solution Approach 2:
The poly sugar-based agent performs multiple functions simultaneously: it provides detergency, anti-redeposition, and soil suspension properties. The versatile poly sugar composition replaces multiple phosphate functions with a single environmentally friendly system that handles various cleaning tasks effectively.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The poly sugar-based composition provides a green alternative for removing protein soils and preventing redeposition, effective on various surfaces, including glass, ceramic, and plastic, with a pH-controlled alkaline solution ensuring adequate detergency without damaging the surfaces.
Implementation Method 1
The poly sugar-based composition provides a green alternative for removing protein soils and preventing redeposition
Implementation Method 2
Alkaline detergents, intended for both institutional and consumer use, typically contain phosphates. Detergency is defined as the ability to wet, emulsify, suspend, penetrate, and dispense soils.
Implementation Method 3
the ability of sodium tripolyphosphate to disperse and suspend soils facilitates the detergency of the solution by preventing the soils from redepositing into the wash solution or wash water

AI summary
A method and composition is provided for removing protein soil and preventing redeposition of soils onto a surface. The method includes introducing a protein-removing/anti-redeposition agent during a washing step of a wash cycle, introducing a cleaning composition during the washing step of the wash cycle, washing the surface of the substrate with the protein-removing/anti-redeposition agent and the cleaning composition during the wash cycle, and subsequently rinsing the surface of the substrate with a rinse aid. The protein-removing/anti-redeposition agent includes a poly sugar and the cleaning composition includes an alkalinity source and a surfactant component. The composition is substantially free of phosphorus-containing compounds and includes less than about 0.05% by weight alkali earth metal.
