Résumé :	Exfoliating body and face cleanser formulations often rely on polyethylene beads to help rejuvenate the skin by removing dead cells. The growing discussion about plastic contamination of the environment, and specifically of marine ecosystems, has raised concern about the use of such microscopic polyethylene particles in a variety of applications. Of the many alternatives that are currently under discussion, hydrated silica stands out as a very economical solution that overcomes the pressing environmental objections to plastic spheres. Because of its hydrophilic nature, hydrated silica easily mixes into aqueous formulations. Experimental evidence is provided that hydrated silica particles are easily removed in waste water treatment plants. The particles are stable in water as well as aqueous anionic surfactant solution, as proven by laser diffraction particle size analysis.
