2. Antiperspirant & Deodorant
A deodorant is a substance applied to the body to
prevent body odor caused by the bacterial breakdown
of perspiration in armpits, feet, and other areas of the body.
A subgroup of deodorants, antiperspirants, affect odor as
well as prevent sweating by affecting sweat glands.

3. Antiperspirants
Antiperspirants are typically applied to the under arms,
while deodorants may also be used on feet and other areas
in the form of body sprays. In the United States, the food
and drug administration classifies and regulates most
deodorants as cosmetics but classifies antiperspirants
as over-the-counter drugs.

4. Perspiration physiology
When the body temperature rises, the sympathetic nervous
system stimulates the sweat glands to secrete water to the
skin surface, where it cools the body by evaporation. Thus,
sweat is an important mechanism for temperature control.

5. Mechanism perspiration control
Sweating allows the body to regulate its
temperature. Sweating is controlled from a center in the
periotic and anterior regions of the brain's hypothalamus,
where thermo sensitive neurons are located. The heat-
regulatory function of the hypothalamus is also affected by
inputs from temperature receptors in the skin.

6. Active ingredient for antiperspirant formulation
▶ Aluminum cholohydrate
▶ Aluminum chloride
▶ Basic aluminum bromide
▶ Basic aluminum nitrate
▶ Basic aluminum iodide
▶ Magnesium aluminum chloride

7. Types of antiperspirant
1.Aerosol
2.Sticks
3.Cream

8. Aerosols
a substance enclosed under pressure and able to be
released as a fine spray, typically by means of a propellant
gas

9. Sticks
A sticks is a solid delivery vehicle cast in an
elongated form. By rubbing a sticks onto a skin a
variety of cosmetics ingredients can be delivered
such as fragrances, coloring agent, and emollients.

10. Cream
a substance applied to the body to suppress or mask the
odor of perspiration or other body odors. (As modifier):
a deodorant spray Compare antiperspirant.

11. Aerosol Deodorants:
a system of colloidal particles dispersed in a gas; smoke
or fog. Of or containing a liquid or gas under pressure for
dispensing as a spray or foam: a deodorant available
in aerosol cans.

12. General mechanism of deodorants
Most antiperspirants contain ingredients called aluminum
salts. The main way in which they work is to dissolve in
sweat and create a thin coating of gel to cover over the
sweat glands. This coating reduces the amount of sweat
released onto the surface of the skin for a number of hours
after the antiperspirant is applied.
