Sweat

Sweat, or so called perspiration, is a necessary physiological process that allows us to maintain a regulated body temperature. It generally presents itself in the armpits, palms, feet, back and front, through the release of a fluid that is secreted by sweat glands found on our skin.

Sweat is predominantly composed of water and minor salts and fats. It is odorless and colorless, and when secreted to the skin surface, evaporates, thereby removing body heat.

It is known as Hyperhidrosis, when perspiration is much more than usual, in the sense that body produced higher amounts of secreted sweat that can make that person self-conscious about the issue as well as lead to esthetic problems.

It is important to know, that underarm odors can vary substantially from person to person. The odor is influenced by the mix of bacteria that colonize the arms, in addition to the composition of the sweat produced.

All Dioxogen® deodorants are antipirspirants and protect against bad odors.

Where do bad odors come from?

We have always associated the underarm odor with sweat produced in this area, but in fact, when sweat is secreted by the sweat glands (eccrine and apocrine), it is odorless.

What actually happens is that the sweat is easily decomposed by the bacteria on the skin, which is directly responsible for producing body odors. The apocrine sweat which is much less abundant than eccrine sweat, is responsible for most of the odor, as it is rich in organic material which is ideal for bacterial growth. However, eccrine sweat is more diluted and has large amount of nutrients; so it indirectly promotes odors as a result of dispersing the apocrine sweat over a greater area of a moist environment, which is necessary for bacterial growth.

Another factor contributing to the foul odors in the armpit is hair, given that it traps apocrine sweat and increases the surface area that is ideal for bacterial growth.

Did you know sweat composition is influenced by recent food intake as well as the physical and physiological state of the body?

Foods such as garlic, onions, and asparagus are well known to have the ability to impart characteristic odors to the body's secretions.

For this reason, products intended to control sweating and odor have two mechanisms:

Deodorant Mechanism:

Refers to the action of preventing the formation of body odors by reducing or eliminating bacteria from the skin's surface. The intention is to stop bacteria from metabolizing the organic material that is produced by sweat; using deodorant can do this without affecting the bacterial flora when the formulations contain antibacterial ingredients or other odorless compositions.

Antiperspirant Mechanism:

Is an indirect process, since by reducing the production of perspiration, prevents the bacteria with nutrients to help proliferate and thereby avoid the onset of body odor.
