Why is there a deodorant with aluminium salts made by Belico?

Alu­mi­nium salts are the only known active ing­re­di­ents which pro­duce a strongly anti­per­spi­rant or sweat-res­trai­ning effect. But the highly effi­cient alu­mi­nium salts are always said to end­anger your health. The claim that they would inc­rease the risk of Alz­heimer's disease has not been proved so far.

A cor­re­la­tion with breast cancer has also been repea­tedly sug­ge­sted. Recently, a rese­ar­cher from the Uni­ver­sity of Geneva has dis­co­vered that alu­mi­nium chlo­ride damages breast cells. Indeed, the alu­mi­nium chlo­ride used in this study was injected directly into the cell cul­ture. From a sci­en­tific point of view, the fact that the alu­mi­nium salts used in deo­do­r­ants can never pene­t­rate cells directly, and the skin anyway pro­vides a natural bar­rier that pre­vents the pene­t­ra­tion of these rather large mole­cules, render the results of this study more than ques­tionable and practi­cally irre­le­vant.

However, the sweat-res­trai­ning effect of the inor­ganic com­pound is estab­lished. Alu­mi­nium chlo­ride acts as a strin­gent nar­ro­wing the sweat gland exit, which in turn very effec­ti­vely reduces the sweat pro­duc­tion. That's why alu­mi­nium salts are also pre­scribed by der­ma­to­lo­gists in recipes against strong swea­ting, because they are the only active sub­stance which has this effect.

Indeed, no pro wit­hout a con: alu­mi­nium chlo­ride can irri­tate the skin and cause local red­de­ning, itching and bur­ning, espe­cially when it is used several times a day. For this reason it is also recom­mended that anti­per­spi­rants should not be used more than twice a day. However, due to the long-las­ting effect, app­lying it once per day is anyway enough.

Deo­do­r­ants are more skin-com­pa­tible than anti­per­spi­rants because they only target the annoying odour of sweat. These deo­do­r­ants pre­vent the for­ma­tion of odours with ing­re­di­ents like zinc rici­no­leate, ethyl­hexyl gly­cerol or tri-ethyl cit­rate that reduce the germs which decom­pose sweat. For it is only the decay of sweat that pro­duces unp­lea­santly smel­ling com­pounds which are res­pon­sible for the typical sweat odour.

Deo­do­rant cry­stals are ano­ther option. They are based on the cry­stal­line rock alunite or alum, which is, in che­mical terms, potas­sium alu­mi­nium sul­p­hate. It also belongs to the family of alu­mi­nium salts and can cause skin irri­ta­tion. Alum has played a role in tra­di­tional hea­ling, it has a blood-stai­ning, astrin­gent and anti­bac­te­rial effect. In deo­do­r­ants (e. g., cry­stal), it helps to close the sweat pores of the body, acting in the same manner as syn­thetic alu­mi­nium com­pounds.

If alum cry­stals are conta­mi­nated with pol­lu­t­ants or heavy metals, the skin-fri­endly pro­perty can be lost.

Con­clu­sion: If you do not only mean to con­ceal unp­lea­sant body odours more or less reli­ably but actually want to reduce your per­spi­ra­tion, you cannot avoid alu­mi­nium salts in deo­do­r­ants. If you want to get deo­do­r­ants wit­hout alu­mi­nium salt because of the media-induced panic, an into­ler­ance to alu­mi­nium salt or inju­ries (from sha­ving), Belico Deo Spray II deo­do­rant is your choice. You may also alter­na­tingly apply both Belico deo­do­r­ants, much redu­cing the amount of alu­mi­nium salts despite maximum effect.
