- Bar Soap
Kicking off our list of the 10 most commonly used products in the world is bar soap, which is actually more eco-friendly than the alternative, liquid soap. Yet while it’s still used in 84% of U.S households, that figure is down from 89% in 2010. The younger generation tends to view bar soap with distaste, believing it’s less convenient and potentially unhealthy. Where bar soap isn’t slipping in usage is at hotels, as U.S hotels alone go through over 90 million bars of soap per year. Unilever plc (ADR) (NYSE:UL)‘s Dove is the dominant brand in bar soap, with 24% market share.
