AI Technical Summary

Technical Problem

Existing ultrasonic dishwasher cleaners cannot effectively utilize ultrasonic energy for synergistic sterilization, especially in their limited ability to remove stubborn biofilms and bacteria. Furthermore, capsaicin has issues with poor water solubility, instability, and irritating residues when used in dishwashers.

Method used

Using β-cyclodextrin-capsaicin-metal-organic framework (β-CD-capsaicin-MOF) powder as the core component for sonodynamic enhancement, it is mixed with the detergent matrix. The resulting detergent can generate more active oxygen under the action of ultrasound, achieving efficient removal of stubborn stains and biofilms. Furthermore, the stability and safety of capsaicin are improved through the encapsulation effect of β-CD.

Benefits of technology

It significantly improves cleaning efficiency, achieves thorough cleaning, enhances the ability to remove proteins, greases, and stubborn biofilms, reduces the risk of irritating capsaicin residue, and is suitable for large-scale industrial production.

Abstract

This invention discloses a sonic dynamics-enhancing cleaning agent for ultrasonic dishwashers and its preparation method, belonging to the field of daily chemical technology. The cleaning agent comprises a sonic dynamics-enhancing core component and a cleaning agent matrix. The sonic dynamics-enhancing core component is β-cyclodextrin-capsaicin-metal-organic framework (β-CD-capsaicin-MOF) powder. The preparation method involves dissolving and crystallizing β-CD, KOH, and capsaicin in a molar ratio of 1:1:1 to obtain β-CD-capsaicin-MOF powder; mixing detergent builders, bleaching agents, enzymes, etc., to obtain the cleaning agent matrix; and then mixing the two components in a specific ratio to obtain the final product. This invention utilizes MOF to encapsulate capsaicin, solving the problems of poor water solubility and residual irritation of capsaicin. Furthermore, it utilizes MOF as a sonic sensitizer to generate active oxygen under ultrasonic action, which, in synergy with physical cavitation, significantly enhances the removal ability of stubborn stains, bacteria, and biofilms, achieving thorough cleaning.
