The government of Rio de Janeiro sanctioned on August 31 law that bans the plastic microspheres of the entire state. The microspheres are made of polyethylene glycol, a petroleum derivative, common in exfoliants.

The companies have 18 months to remove the raw material of any cosmetic product, personal hygiene or cleaning, produced or commercialized in Rio de Janeiro, under penalty of fines and other sanctions.

Report on the oceans of the United Nations Environment Program (UNEP) has warned of the accumulation of these particles – not biodegradable, or filterable, ie they are not retained in sewage treatment plants and go to the river system, causing mortality of marine fauna and, also, drinking water for humans.
