Biodegradable Alkaline Cleaner with UV-Traceable Surfactant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alkaline cleaning compositions face challenges with instability, environmental unfriendliness, and the need for additional sanitizing steps, particularly in removing hard-to-clean soils and validating cleaning processes, due to the use of non-biodegradable and potentially toxic components.
Innovation Solution
A stable, phosphate-free, aqueous alkaline cleaning composition combining sodium hydroxide as an alkalinity source with a biodegradable surfactant system including nonionic surfactants, hydrotropes, and a UV-analyzable surfactant, along with a biodegradable chelating agent, which provides enhanced antimicrobial and virucidal efficacy without requiring separate disinfecting steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional alkaline cleaning compositions are used, then cleaning performance is achieved, but stability and environmental friendliness deteriorate due to non-biodegradable and toxic components
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by substituting non-biodegradable surfactants and chelating agents with biodegradable alternatives. Specifically, it uses biodegradable surfactants (such as alkyl polyglucosides, alcohol ethoxylates) and biodegradable chelating agents (such as EDTA alternatives like GLDA, MGDA) while maintaining effective cleaning performance. This parameter change resolves the contradiction by improving environmental friendliness without sacrificing stability or cleaning efficacy.
2Reliability
If multiple cleaning mechanisms are combined for hard-to-clean soils, then cleaning effectiveness improves, but composition complexity increases
Solution Approach 1:
The patent merges multiple cleaning mechanisms into a single integrated composition. It combines surfactants (for emulsification and wetting), chelating agents (for metal ion sequestration), and alkaline components (for saponification) into one synergistic formulation. This merging approach achieves effective cleaning of hard-to-clean soils while managing composition complexity through careful selection of compatible biodegradable ingredients that work together rather than as separate additives.
3Reliability
If separate sanitizing steps are added, then antimicrobial efficacy improves, but process time and complexity increase
Solution Approach 1:
The patent creates a multi-functional cleaning composition that simultaneously provides cleaning and sanitizing capabilities. It incorporates biodegradable surfactants with inherent antimicrobial properties and combines them with biodegradable chelating agents and alkaline components that work together to achieve both cleaning and disinfection in a single step. This eliminates the need for separate sanitizing steps, reducing process time while maintaining effective antimicrobial efficacy.

AI summary
An aqueous, alkaline cleaning composition for use on hard-to-clean soils, encountered in pharmaceutical, personal care, food and cosmetic manufacturing, comprising a source of alkalinity, a biodegradable surfactant system further comprising one or more surfactants, one or more hydrotropes, and a UV-analyzable surfactant, and a biodegradable chelating agent. The composition offers unique advantages of stability over the expected shelf life, low-foaming property, phosphate-free and biodegradable components, and unexpectedly enhanced antimicrobial, including virucidal, activity in one cleaning composition. The UV-analyzable surfactant allows for validation of cleaning processes using known techniques for manufacturers who are required or desire to do so.
