GlycolsUn glycol ou diol est un composé chimique organique portant deux groupes hydroxyle (-OH).
Lorsque les deux groupes hydroxyle sont portés par le même atome de carbone, on parle de diol géminal. Parmi ceux-ci, on compte par exemple le méthanediol (H2C(OH)2) ou le 1,1,1,3,3,3-hexafluoropropane-2,2-diol ((F3C)2C(OH)2), la forme hydratée de l'hexafluoroacétone.
On parle de diol vicinal lorsque les deux groupes hydroxyle sont en position vicinale, c'est-à -dire attachés à des atomes de carbone adjacents. On compte parmi ceux-ci l'éthane-1,2-diol ou éthylène glycol (HO-(CH2)2-OH), un composant courant des produits antigels ou le propane-1,2-diol (propylène glycol, HO-CH2-CH(OH)-CH3).
Parmi les composés avec des groupes hydroxyles bien plus éloignés on compte le butane-1,4-diol (HO-(CH2)4-OH) ou encore le bisphénol A.

| Résumé : |
Glycols, including 1,3-butylene glycol (1,3-BG), play an important role in the development of personal care products, including creams, sunscreens, shampoos, body washes and more. As concern about petroleum-based ingredients continues to grow, consumers have become increasingly concerned about the ingredient sources and manufacturing processes involved with making their products, including consideration of ingredient's lifecycle impact and overall natural and sustainability attributes. To adress these concerns, Genomatica has conducted a systematic study, called a life cycle assessment (LCA), on the environmental impact of the produtcion process they've developed for their naturally-sourced, bio-based 1,3-BG (known as Brontide), as compared with a petroleum-based alternative. The results show that conventional1,3-BG production processes starting from petroleum-based feedstocks have a significanly higher global potential and energy demand from renewable plant-based feedstocks. The results of this study will help personal care and cosmetic's formulators choose ingredients that have a reduced environmental impact while also addressing their customer's increasing desire for more natural products, helping manufacturers work toward a more sustainable future. |
