Pentylène glycolLe pentane-1,2-diol est un alcool de formule brute C5H12O2. C'est une molécule chirale car l'atome de carbone 2 portant un hydroxyle est asymétrique. Le pentane-1,2-diol se présente donc sous la forme de deux énantiomères : le R-pentane-1,2-diol et le S-pentane-1,2-diol.

| Résumé : |
The increasing consumer demand for more natural cosmetics is a continuing global trend. The manufacturers of cosmetics and cosmetic ingredients therefore share a common goal : finding cost-effective bio-based ingredients that work as well as their petrochemical-derived counterparts. Recently, a nature-derived version of the popular synthetic alkanediol "pentylene glycol" has become available on an industrial scale at a competitive price (trade name: "Pentiol Green+", by Minasolve). It is produced on the basis of corn cabs and sugarcane bagasse and provides the same multi-functionality as its petrochemical equivalent : skin moisturization, emolliency and antimicrobial protection. However, the novel natural origin of pentylene glycol makes it possible to also use it in eco-labelled products. It increases the degree of naturality of cosmetics and reduces their carbon footprint. Furthermore, being an eco-sourced solvent, "green" pentylene glycol provides added value for extracting plant materials. |
