Dispersant or deflocculation agents:

Theses are polymerized organic salts of sulfonic acid of both alkyl-aryl or aryl-alkyl types that can alter the surface charge of particles through physical adsorption. Their mechanism of action is not clear, but they appear to function by producing as negatively charged particle or increasing the negative charge already present in order to aid dispensability.Unlike surfactants, these agents do not appreciably lower surface and interfacial tension; hence they have little or no tendency to create foam or wet particles
