Unilever is one of the world's largest packaged goods companies operating in many countries. In the late 1990s, it streamlined its vast portfolio and focused on brands like Dove. Dove soap was launched in 1955 containing a patented mild cleansing ingredient positioned as a beauty bar that moisturizes skin unlike drying regular soap. Advertisements showed cream being poured into the bar. A dermatologist study found Dove dried and irritated skin less than other soaps, leading Unilever to aggressively market Dove and gain over 24% of the market by 2003. Dove has since expanded into body wash, hand wash, face care, hair care, deodorant, and body lotions.
