Aerosol sprays are the most popular deodorant format, due to their ease of application and instant dryness. However, consumer preferences for deodorant sizes vary by region. India, the most dynamic market, shows preference for larger sized sprays, as they are often shared by the family. By contrast, growing environmental concerns in Western Europe prompted Unilever to release a compact 75ml version across its leading brands in the UK, a trend set to shape the deodorants market in the future.
