While Para urinal blocks are often thought of as absorbents, they actually fall into the neutralizer category. Neutralizers use a chemical reaction where an odor causing acid gives off a proton to a base. The reaction is said to neutralize the odor.
Para urinal blocks should only be used in well ventilated areas since they have been found to contain a chemical that is a suspected cancer-causing agent.
