The name 'Ivory' refers to a series of products created by the Procter & Gamble Company (P&G), including varieties of a white and mildly fragranced bar soap, that became famous for its pure content and for floating in water. Over the years, the bar soap has been altered into other varieties. P&G research revealed in 1992 indicated work in progress to create other varieties that do not float as the original and would sink due to the altered ingredients but avoid dissolving too fast. New varieties of Ivory soap contain glycerin, do not dry the skin as quickly, and do not float either. In October 2001, P&G tested the sinking bar soap as part of an advertising campaign to see if people would notice the sinking bars, even if given a cash reward.
