| Résumé : |
There have been a number of papers published on the use of betaine in cosmetics. The objective of this article is to review these and add some new data or new insights on how this ingredient could be used in the future. Betaine or trimethyl glycine is a very simple, common molecule found in nature. Its name is derived from the sugar beet (beta vulgaris). Its commercial for is obtained from the process of making sugar out of sugar beets by chromatography of the molasses. It can ba labelled as "natural" and is available in large quantities at a very affordable pricez. It is a small trimethylated aminoacid existing in a switterionic form at neutral pH. Because of its structure, betaine can easily form hydrogen bonds with water and other molecules conferring it very unsual properties and in particular helping solubilise some other molecules.
It is non-toxic (LD50 is 11.2 g/Kg) and is used in food supplements ; it is highly soluble in water (up to 55 %) and chemically stable. It has been shown to be secreted in marine microorganisms to help them resist osmotic stress.
In their article published in 2000, Rigano et al. showed some of the applications in cosmetics. These include its biocompatibility, its ability to reduce the irritation effect of surfactants, its solvent capacity as well as its special skin feel. |
