Aluminum salts

chrono Reading time: 0 min.

What are aluminum salts?

Aluminum salts have been widely used for almost a century: as an adjuvant in vaccines, as a coagulant in water treatment and as an antacid drug for stomachs.

In our products, they appear in the list of ingredients on the packaging, under the names ALUMINUM SULFATE, ALUMINUM CHLORIDE or ALUMINUM CHLOROHYDRATE.

 

Where do they come from?

Where do they come from?

Aluminum is the most abundant metal in the earth's crust and the third most abundant element after oxygen and silicon. As a result, aluminim is naturally present in small amounts in food and water and is also naturally present in mineral ingredients such as kaolin, clays, perlite, talc or diatomaceous earth used in a range of cosmetic products.

Alum stone, which contains a soluble aluminum salt, has long been known for its astringent properties.

The soluble aluminum salts used in cosmetics are synthesized.

Aluminum is also present in insoluble form in the coloured pigments used in make-up or in toothpastes to remove tooth discolouration caused by tea or coffee.

Why are they used?

Aluminum salts typically used in antiperspirants are the aluminium chlorohydrates. They are effective in combatting perspiration and associated odours. They reduce sweating by forming small aggregates at the mouth of the ducts through which sweat flows.

  • Anti-perspirant

  • Anti-odour

Why are they being questioned?

Aluminum salts are accused of playing a role in the appearance of breast cancer and Alzheimer's disease.

The Facts:

  • The safety of aluminum salts has been reviewed by numerous international expert groups over the past 10 years including by the World Health Organization, the US Food and Drug Administration, the American Cancer Society and the French Agency for the Safety of Health Products. All confirm that current knowledge does not support the role of aluminum salts used in cosmetics in breast cancer or Alzheimer's disease. These findings are fully consistent with the very low ability of aluminum salts to penetrate the skin.
  • The European Union's Scientific Committee on Consumer Safety (SCCS) as well as other EU regulators such as the German Federal Institute for Risk Assessment (BfR) have clearly stated that the available information does not support concerns about the carcinogenic potential of aluminum compounds, including aluminum salts. The SCCS also mentions a clinical trial, which showed that about 0.002% of the aluminium in an antiperspirant penetrates the skin. This very small amount is consistent with its surface mode of action. The SCCS also indicates that the greatest exposure to aluminum comes from dietary intake. More information here.
  • The use of cosmetic products containing aluminum represents no risk and is therefore perfectly safe for the consumer.

How are they used in our products?

Text block 5

We use aluminum salts in our antiperspirant products, in compliance with consumer safety.

In response to requests from some of our consumers, we are also developing deodorants free from aluminum salts and are working on alternative solutions that are just as effective.
