SCA endorses products with the Allergy Certified logo, that do not contain aluminum commonly used in oral care & personal hygiene products. Using antiperspirants or deodorants that contain aluminum, are not scientifially proven to increase the risk of getting breast cancer or Alzheimer’s, in fact the body cannot absorb aluminum topically. The American Cancer Society (ACS) states that the potential risk in using products that contain aluminum, is due to the fact that they can cause skin irritation, especially when used after shaving or if a cut becomes infected & then you apply the aluminum product. Fact: almost all carcinogens in the body are removed through the liver & kidneys (not the armpits), then excreted out of the body.

Aluminum is one of the most common elements found on earth, it occurs naturally in plants, vegetables & the human body. When you see aluminum on a product label, experts advise that the concern is for the fact that it’s purity is not tested, for the vast majority it is not a pure substance at all.

Studies do not show an increased risk of cancer amongst deodorant & antiperspirant users, or amongst women who shaved before using products that contained aluminum. When used in deodorants & ntiperspirants, the aluminium salts work by blocking the sweat glands & not the lymph nodes that do remove toxins, this function does not remove toxins by sweating.


Aluminum Chloride (is a neurotoxin): CAS No: 7446-70-0 (anhydrous). CAS No: 10124-27-3 (hydrate). CAS No: 7784-13-6 (hexahydrate). Other popular aluminum in deoderants and antiperspirants: CAS No: 12042-91-0 (chlorohydrate) CAS No: 12042-91-0 (chlorohydroxide). CAS No: 57158-29-9 (zirconium). CAS No: 134910-86-4 (TetrachlorohydrexGly) "There are 18 aluminum-based salts recognized by the US Food and Drug Administration to reduce underarm wetness. These include a number of forms of aluminum-based salts including aluminum chloride, aluminum chlorohydrate(s), and aluminum zirconium salts."

Common compounds in cosmetic ingredients:

  • aluminum chlorohydrate and aluminum chloride, contain trace quantities of pure aluminum used in antiperspirant, deodorants & medications.

  • alumina or aluminum oxide or aluminum hydroxide is not "aluminum," it is a mixture of minerals including aluminum, silica, chloride or zirconium & oxygen.

  • magnesium aluminum silicate is not aluminum, it is refined from clay & used as an absorbent cosmetic ingredient that is unable to penetrate the skin.

  • aluminum starch derived from a reaction of plant ingredient such as starch. It is used as a thickening & absorbent cosmetic ingredient.


Deodorants; "antiperspirants, deodorants and astringents in skin fresheners and other personal care products." - NICNAS also reports commercial use in; surface treatments, water purification, dyeing textiles, odour blockers, cleaning and washing agents and adhesives.


Aluminum chloride may cause skin irritation, including contact dermatitis. It has many industrial uses and is commonly used in deodorants.

  • "Aluminum chloride has many industrial uses, but is also used in deodorants. It plugs up sweat glands and closes pores to prevent sweating. In rare cases, aluminum chloride exposure can cause Frey's Syndrome, which results in excessive sweating on the face." And, "Side Effects. Aluminum chloride is a definite life saver in the sweating department, but there are some side effects. When it comes into contact with skin it can cause burning, stinging, itching, and tingling." -

  • "Aluminum chloride is the partially neutralized form used in cosmetic antiperspirants, while aluminum chloride hexahydrate is among the most effective antiperspirants currently available.[58] Several studies have shown that aluminum salts cause an obstruction of the distal sweat gland ducts." -

  • Cosmetic allergy is common: "Deodorants and antiperspirants are two of the most commonly used cosmetic products, with millions of consumers applying these products to their axilla everyday. Deodorants are used to mask odor; whereas, antiperspirants are used to reduce the amount of sweat produced." - NCBI. And, "aluminum exposure from deodorant use has been blamed for the rising incidence of Alzheimer's Disease (AD). A recent review of 46 studies looking at aluminum exposure and risk of developing AD concluded that aluminum is, in fact, a risk factor for the development of disease."
