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.
● 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 perfectly consistent with the very low capacity of aluminium salts to penetrate the skin. More information here.
● A recent study has shown that ~ 0.01% of the aluminium present in an antiperspirant product penetrates the skin, which demonstrates it only pursues an action at surface level of the skin.
Why and how do we use them?
We use aluminium salts in our antiperspirant products in a way that ensures the safety of our consumers.
To meet the demands of some of our consumers, we also develop deodorants without aluminium salts and work on equally effective alternatives.
