AI Technical Summary
Technical Problem
Endoscopes and their channels are difficult to clean due to narrow inner diameters, non-wettable materials, and biofilm formation, leading to infections like CRE, which conventional cleaning methods struggle to address effectively.
Method used
A cleaning composition incorporating particulate superabsorbent polymers (PSAP) with shear-thinning properties and microfibrillated cellulose (MF) enhances cleaning efficiency by creating localized high shear stress and effective contact with contaminants.
Benefits of technology
The composition significantly reduces biofilm removal time from endoscope channels, achieving rapid and thorough cleaning even in narrow, complex structures.

Abstract
[Solution] In particular, cleaning compositions are provided that comprise a carrier fluid that comprises a polymer comprising a particulate superabsorbent polymer (PSAP), wherein the PSAP is present in the cleaning composition at substantially or above a percolation volume fraction, and the cleaning composition can be passed over a surface driven by a pressure drop effective to make the composition effective for traditional biofilm (TBF) cleaning and effective for protein cleaning.
