Which active ingredient is effective in controlling body odour?

The active ingredient that is effective in controlling body odour is aluminium salts. These compounds work by reducing perspiration. When applied to the skin, aluminium salts react with sweat to form a gel-like substance that temporarily blocks the sweat glands. This results in a decrease in the amount of sweat that reaches the skin's surface, thus limiting moisture that can contribute to body odour.

While alcohol and antiseptics may have some antibacterial properties that can reduce odour-causing bacteria, they do not address the underlying issue of sweat production. Fragrance, while it can mask odour, does not prevent odour from forming. Therefore, aluminium salts are specifically designed for sweat reduction and are a more effective choice when it comes to controlling body odour.
