abradant
Surface roughening agent
An abradant is a substance used for grinding, polishing, or wearing away surfaces—sandpaper, pumice, or industrial grit.
The word functions as both noun and adjective: abradant particles in the cleanser.
It's a technical synonym for abrasive, found mainly in manufacturing and materials science contexts.
