- secreted aqueous secretion There are three types of sweat glands in the skin, namely, apocrine, eccrine, and apoekrine sweat glands (Int J Cosmet Sei. 2007 Jun;
- the eccrine sweat glands in humans are distributed practically throughout the body and can produce significant amounts of a clear, odorless secretion that is over 99% water.
- the apocrine sweat glands occur only in the hairy body areas of the armpit and genital region and on the nipples. They produce small amounts of a milky secretion that contains proteins and lipids and is chemically neutral.
- Sweating also known as transpiration, is an effective mechanism to release excess heat and thereby regulate body temperature.
- the volume-rich aqueous secretion of the eccrine glands which can produce up to 2-4 liters per hour or 10-14 liters a day in adults, is used for this purpose.
- the sweat - especially the secretion of apocrine sweat glands - is also signaled by the sense of smell. In humans, the apocrine sweat plays in particular in connection with the emotional or stress related
- Cosmetic antiperspirants or deodorants / deodorants are used to eliminate body odor or to reduce their formation.
- Body odor arises when the per se odorless fresh sweat by microorganisms such. Staphylococci and
- Antiperspirants are antiperspirants which, in contrast to the deodorants which generally prevent microbial decomposition of already formed perspiration, are said to prevent the secretion of sweat at all.
- AT preparations may additionally contain substances which inhibit the microbial degradation of the perspiration, such as, for example, Triclosan.
- Triclosan has an effect against gram-positive and gram-negative bacteria as well as against fungi and yeasts, which results in a deodorizing, but no antiperspirant effect, as no influence on the sweat secretion can be deduced from the influence on the bacterial skin flora.
- Odor neutralization (masking), influencing of bacterial metabolisms, the pure perfuming as well as the use of precursors of certain perfume components, which are converted by enzymatic reactions to fragrant substances.
- Antiperspirant active agents, etc. achieved by a "blockage of the sweat gland". They work by blocking sweat gland excretions by precipitating them together with the skin's own proteins, leading to so-called plugs.
