Dry Biocidal Absorbent Composition for Bodily Spill Cleanup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid disinfectants for cleaning bodily spills are hazardous to store, ineffective for solid or semisolid spills, and require additional safety measures, while dry absorbent materials lack effective biocidal properties.
Innovation Solution
A dry absorbent composition comprising an interspersed mixture of expanded perlite and a dry biocide, which absorbs and disinfects spills without the need for water, providing quick-acting biocidal activity against a broad spectrum of harmful organisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid disinfectants are used to clean bodily spills, then biocidal activity is achieved, but storage becomes hazardous and additional safety measures are required
Solution Approach 1:
The invention changes the physical state of the biocidal agent from liquid to dry powder form. This parameter change eliminates the storage hazards associated with liquid disinfectants (flammability, spill risks, vapor inhalation) while maintaining biocidal activity. The dry powder formulation achieves this by using a different physical state that is inherently safer for storage and handling.
Solution Approach 2:
The invention utilizes phase transition by converting the biocidal active ingredient from liquid phase to solid phase (dry powder). This phase transition fundamentally changes the safety profile during storage and handling, eliminating many of the hazards associated with liquid storage while preserving the disinfecting capability when applied to spills.
2Reliability
If liquid cleaners are used, then biocidal effect is achieved, but they do not effectively aid the removal of solid or semisolid spills
Solution Approach 1:
The invention merges two previously separate functions into a single dry powder formulation: absorption of liquid/semisolid spills and biocidal disinfection. The dry powder composition simultaneously performs both functions - it absorbs the spill material while delivering biocidal activity, eliminating the need for separate cleaning and disinfection steps.
Solution Approach 2:
The dry powder composition is designed to be multi-functional, serving both as an absorbent for solid/semisolid spills and as a biocidal disinfectant. This universal formulation can handle various types of bodily spills (blood, urine, feces, vomit) while providing comprehensive disinfection, making it suitable for multiple cleaning scenarios with a single product.
3Ease of operation
If dry absorbent materials are used, then spill absorption is improved, but biocidal properties are insufficient
Solution Approach 1:
The invention creates a composite material by combining absorbent carrier materials (such as cellulose, starch, or silicate minerals) with biocidal active ingredients in a dry powder formulation. This composite structure ensures that the biocidal agent is effectively delivered to the spill while the carrier provides absorption and facilitates easy application and removal.
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 composition effectively absorbs and disinfects bodily spills, reducing bacteria, viruses, and fungi by ≥ 4 logs within minutes, is easy to handle and dispose of, and offers a broad spectrum of biocidal activity against various microorganisms.
Implementation Method 1
The silicate mineral material is expanded. An expanded mineral material can be obtained by heating, which can cause components within the material, for example water, to vaporise. This can result in a lower density, particulate, material
Implementation Method 2
The coated absorbent material absorbs the sanitation agent to form the cleaning composition
Implementation Method 3
a dry biocidal absorbent composition comprising an interspersed mixture of separate particulates of a dry absorbent silicate mineral material and a dry biocide

AI summary
A dry biocidal absorbent composition comprises an interspersed mixture of a dry absorbent silicate mineral material and a dry biocide. The absorbent silicate mineral material may comprise expanded perlite and/or exfoliated vermiculite. The biocide may comprise sodium dichloroisocyanurate or a hydrate thereof. The composition may be used for cleaning up a bodily spill from a floor or other surface.
