Antiperspirants: how do they work?
Antiperspirants - next of kin deodorants, compositions, masking unpleasant body odor. Over the past few decades it antiperspirants confidently occupied leading positions in the daily hygiene. In contrast, deodorants, only gives the skin a fragrance, antiperspirants control the process of perspiration by means of special chemicals, mainly derivatives of zinc and aluminum.
It is curious that in itself sweat released from the pores of the human body during the process of thermoregulation, absolutely transparent and devoid of any odors. Armpits smell, not because we sweat, and due to the fact that, without having to evaporate sweat becomes a breeding ground for bacteria. Tight and synthetic clothing, hair in the armpits, the individual characteristics of the body, enhance the process and, consequently, the smell.
Deodorants contain alcohol, in general, provoking sweating, but killing for some time, "fragrant" bacteria.Antiperspirant does not stand out and sweat thereby depriving the bacteria culture medium. The reaction of the aluminum-based chemicals (the vast majority of the most popular and effective antiperspirants contain aluminum chloride, aluminum chlorohydrate, aluminum-zirconium, etc.) forms a gel plug overlying tubule outputting sweat on the skin surface, moreover, the metal salt pores that also prevents the escape of liquid.
By the way, recently appeared in Russiaantiperspirants crystalsKnown in the East since ancient times - a form of alum, that is, contrary to advertising, the physical action of the crystal is different from the usual work of a ball or stick. One can not say that it isbest antiperspirant. Another thing is that it does not contain fragrances and extremely economical in use. It is worth to learn also that the component aluminum zirconium tetrahlorogidreks in contact with human sweat can ruin clothes, forming a hardening in areas of constant use antiperspirant and leaving yellow stains on light fabrics. So to the actual quality of those nasty sweat marks have no relationship, blame Mismatched antiperspirant.
The modern formula, soft and balanced effect on the skin and is used today by most manufacturers podavlyayushim antiperspirants, was patented in the early forties of the last century a famous Cosmetic Chemists of Illinois Dr. Jules Bernard Montigny. Thus, the first "real" was the American antiperspirant spray Stopette. It was he who opened a new era of hygiene and cosmetic products was named "best antiperspirant 50s ", which is not surprising - the competition he did not have.

Antiperspirants and health
Since then, as antiperspirants are widespread, tireless researchers began to comprehensively examine their effect on the human body.

However, more recent data refute such data.

Also, experts warn against the use of antiperspirants, enriched with antibacterial additives (triclosan, chlorhexidine). On the one hand, these products provide a double whammy, finishing off those bacteria that have decided to make money after all then precipitated. On the other - antibacterial ingredients leave behind a scorched field, sparing natural healthy skin flora and negatively affecting the local immunity.
Aluminum-containing antiperspirant active can cause allergic reactions, and alcohol in their composition - irritate sensitive skin. In order to prevent these troubles, issued bealkogolnye antiperspirants with soothing and caring additives, as well as products that use alternative natural substances that constrain sweating - such as oak bark, mica, tea tree oil and sandalwood.

Doctors recommend regular basis to give the skin a rest from antiperspirant, do not use it in predictable periods of active sweating (during sports, sauna, work in the country and so forth.), When the output of the free liquid from the pores should not interfere with anything. Also, before going to bed or applying a new layer of antiperspirant necessarily should be washed off the old, or plug in the sweat glands can create a real "traffic jam" and form a painful swelling, which will have to be removed by a doctor. And, of course, apply antiperspirant always necessary to completely clean, dry skin - otherwise its application simply does not make sense.
