What is the primary function of a deodorant?

The primary function of a deodorant is to prevent body odour. Deodorants are specifically formulated to target the bacteria on the skin that cause unpleasant odours when they break down sweat. By using active ingredients, deodorants inhibit bacterial growth and neutralize the odour caused by perspiration.

While some products may offer additional properties, such as reducing moisture or enhancing fragrance, the central purpose remains focused on preventing body odour. This emphasis on combating odour is what differentiates deodorants from antiperspirants, which primarily aim to reduce sweat production itself. Understanding this key function is essential when considering the various types of personal hygiene products available.
