Where do they come from?
Aluminium is the most abundant metal in the earth's crust and the third most abundant element after oxygen and silicon.
Alum stone, which contains an aluminium salt, has long been known for its antiperspirant properties.
The aluminium salts used in our products are synthesized.
What are they used for?
Aluminium salts typically used in antiperspirants are the aluminium chlorohydrates. They are effective in combatting perspiration and associated odors
They reduce sweating by forming small crystals at the mouth of the channels through which sweat flows
Insoluble forms of aluminium are also used in the colored pigments of lipsticks and in toothpastes to eliminate tooth staining due to tea or coffee
Why are they questioned?
Aluminium salts are accused of playing a role in the development of breast cancer and Alzheimer's disease.
A recent study has shown that ~ 0.01% of the aluminium present in an antiperspirant product penetrates the skin, which demonstrates only a negligible amount of aluminum is absorbed
The safety of aluminium salts have been examined by many international expert groups over the last 10 years including the World Health Organization, the US Food and Drug Administration, the American Cancer Society as well as the French Agency for the Safety of Health Products.
All confirmed that current knowledge does not support the link between aluminium salts used in cosmetics and breast cancer or Alzheimer's disease. These conclusions are consistent with the limited capability of aluminium salts to penetrate the skin. More information here.
Why and how do we use them?
We offer both antiperspirant and deodorant products to accommodate diverse consumer needs.
To meet the demands of some of our consumers, we also develop deodorants without aluminium salts and work on equally effective alternatives.
