AI Technical Summary
Existing technologies struggle to maintain the stability of alkaline electrolyzed water at high pH levels. Quaternary ammonium salt bactericides are deactivated and prone to turbidity in strongly alkaline environments. Highly alkaline electrolytes are highly corrosive to nonwoven fibers, leading to fiber embrittlement and a decrease in the physical strength of wet wipes.
By controlling the Na⁺ ion content in alkaline electrolyzed water to 80-86 mg/kg, adding an electrolyte composition of sodium chloride and sodium hydroxide and benzalkonium chloride stabilizer, using a three-layer composite nonwoven fabric partitioning treatment technology and buffer layer formation, combined with plant essential oil microcapsules and irradiation sterilization, the long-term compatibility and synergistic stability of the electrolyte, bactericide and nonwoven fabric carrier are ensured.
It achieves long-term stability of alkaline electrolyzed water at pH values greater than 12, has a high quaternary ammonium salt activity retention rate, avoids fiber embrittlement and chemical residues, and meets food contact safety standards.
