Antiperspirant Scrap Reclaiming via Phase Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of consumer care products like antiperspirant/deodorant generates significant scrap material, increasing costs and environmental impact, necessitating the development of processes to reclaim and reuse formula components.
Innovation Solution
Methods involve melting scrap antiperspirant compositions to separate solid and liquid phases, treating the liquid phase to reclaim components, and saponifying the oil/wax phase to form reusable soap materials, including the recycling of antiperspirant actives and emollients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If scrap antiperspirant compositions are disposed of, then production costs are reduced, but environmental impact increases and valuable components are lost
Solution Approach 1:
The patent applies discarding and recovering by separating the scrap antiperspirant composition into useful phases (oil/wax phase containing emollients and actives, and solid phase containing inerts) and recovering the valuable components for reuse in new product formulation, thereby eliminating waste while preserving valuable substances
Solution Approach 2:
The patent extracts the oil/wax phase from the solid antiperspirant composition through melting and phase separation, isolating the valuable emollients and antiperspirant actives from the inert solid components for subsequent treatment and reuse
2Ease of manufacture
If scrap materials are reclaimed and reused, then production costs are lowered and sustainability is enhanced, but processing complexity increases
Solution Approach 1:
The patent segments the scrap antiperspirant composition into distinct phases (liquid oil/wax phase and solid phase) through melting and settling, allowing separate treatment and reuse of valuable components while simplifying the overall processing approach
Solution Approach 2:
The patent utilizes parameter changes by melting the solid antiperspirant composition to a liquid state to enable phase separation, then cooling to allow settling into distinct phases, facilitating component recovery through physical state transitions
3Manufacturing precision
If the solid phase is separated from the oil/wax phase, then component recovery is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-melting the solid antiperspirant composition before phase separation to facilitate easier and faster separation into liquid and solid phases, reducing the overall processing time while maintaining separation purity
