Lifebuoy soap was introduced in 1894 in England by Lever Brothers to help stop the spread of cholera. It entered the Indian market in 1895 and became the largest selling soap brand in India by 1940. Over time, Lifebuoy expanded its product line and used various advertising campaigns promoting hygiene and health to establish itself as a family brand focused on preventing disease. It faces competition from other soap brands but maintains market share through community initiatives and social marketing campaigns.
