Clay based spherical antimicrobial granules: UnileverRecent Research Landscape

Standard antimicrobial powders suffer from poor flowability and uneven distribution in composite materials. Engineering the morphology into spherical clay-based granules ensures uniform active ingredient dispersion and controlled release rates.

What technical problems is Unilever addressing in Clay based spherical antimicrobial granules?

Pathogen transmission via surfaces

(7)evidences

Uncontrolled proliferation of pathogens on surfaces leads to infection transmission. Mitigating this risk provides a critical safety advantage in public and clinical environments.

Microbial contamination in formulations

(2)evidences

Uncontrolled growth of pathogens in porous or bulk materials leads to degradation and health risks. Establishing antimicrobial properties within a stable granular form prevents material spoilage and cross-contamination.
