The use of nano-ingredients in cosmetic products is subject to some controversy. Unfortunately one often forgets that nanoparticles are not the same in all cases. A basic distinction must be made between unstable nanoparticles and insoluble particles. As far as our products are concerned, we only use unstable nanoparticles, known as liposomally encapsulated nanoparticles. These liposomes have been used in premium cosmetic products for the past 20 years. Experts have praised liposomes as a breakthrough in cosmetics production. For the past 20 years or more, there has been no evidence of any harmful effect of such liposomes.

There are no indications regarding the risk posed by unstable nanoparticles in the current statement of the SSCP (Scientific Committee on Consumer Products), a scientific committee at EU level, under the title "Preliminary Opinion on the Safety of Nanomaterials in Cosmetic Products", dated 19/06/2007.

The US Cosmetics and Toiletries Association (CTFA) describes the nanoparticles currently in use as safe (article by S. Pittman, dated 21/09/2006), as the particle sizes used in cosmetic products are unable to penetrate the skin and therefore cannot be absorbed by the body. ("The general scientific consensus is that there's no risk to human health.")

Opinions expressed in Germany have been similar, with Andreas Hensel (of the German federal institute for risk assessment) writing as follows: "Several experiments have confirmed that ... nanomaterials do not penetrate healthy human skin cells, but remain on the skin surface ... so far the BfR [German federal institute for risk assessment] is unaware of any case in which damage to health has been proven to have been triggered by nanoparticles or nanomaterials."

In addition to the above, all our raw materials are tested for toxicological safety by our suppliers. The safety of the products is also ensured by carrying out various tests in our laboratories or by having the products tested by independent dermatological institutes.

Our chemists then evaluate the safety of the cosmetic product with regard to consumer health in accordance with the Cosmetics Ordinance § 5b, Paragraph 2. Only once all tests, evaluations and other results are in accordance with the specifications, is the product released for production and distribution.
