In spite of deodorants class of antiperspirants are considered as drugs. Antiperspirants aim to cease or significantly diminish process of perspiration and thus cut down the damp environment where bacteria develop.
Antiperspirants work to preclude perspiration by affecting sweat gland and as well as blocking the pores with such strong astringents as aluminum salts so that the pores can’t excrete sweat. The clogging of sweat glands decline the volume of sweat released in the underarms.
Antiperspirants are designed to be used for the armpits, while deodorants may also be applied to feet and other areas of body as well. Due to they don’t interfere with sweating which is a natural process of body cooling, deodorants are more desirable to apply.
In spite the fact that according to recent research, antiperspirants contained aluminum salts are safe; aluminium in very high doses has been considered as a neurotoxin and it can adversely impact on the blood-brain barrier and has hostile epigenetic effects.
Aerosol antiperspirants gained popularity due to they dispense a spray without contact with the underarm area. Though, in 1977 the Food and Drug Administration (FDA) prohibited the active ingredient aluminum used in aerosols, due to harmful effect of inhalation during long time and whereas, Environmental Protection Agency (EPA) limited the application of propellants used in aerosols because these gases promote to destroy the ozone layer.
As the popularity of aerosols began to decrease, roll-on forms antiperspirants became more popular. Nowadays, stick form is the most popular type of deodorants.
