While doing some research today, I came across a statistic that astounded me. The most popular deodorants in Australia are still sprays. According to 2005 figures, sprays make up 62% of Australian retail sales of deodorants, followed by roll-ons (28%), sticks (5%) and pumps (4%). According to the Global Market Information Database report that I looked at (Deodorants - Australia / Country Report / 4 May 2006), the spray deodorant sector faces challenges, including "environmental concerns". Well I should hope so!
