- Body odour is caused by the bacterial decomposition of the sweat. A deodorant is used to prevent this odour.
- Deodorants contain parabens (methyl, ethyl, propyl, benzyl and butyl) and also alcohol in large proportions. Aluminium compounds and silica are also used.
- Types of deodorants are :
(a) Ordinary deo: It contains a smaller proportion of aluminium. It decreases the odour of the sweat.
(b) Antiperspirant deo : This decreases the extent of sweating. It contains about 15% of aluminium chlorohydrate. It clogs the sweat pores on the skin.
(c) Clinical deo : Some people sweat heavily and it has harmful effects on the skin. Clinical deo is meant for such people. It contains 20 to 25% aluminium. It is used during the night.
