Super Refined™ PGML is a high purity mixture of propylene glycol and esters of lauric (C12) acid. More specifically, as part of the Type II classification, it has at least a 90% concentration of monoesters, with the remaining percentage being diesters. In addition to being a low HLB emulsifier, it also has emolliency, humectancy, and skin penetration properties. Super Refined™ PGML also has a very low impurity profile, which ultimately improves its shelf life over competitor products. This includes reductions in problematic impurities like aldehydes, acids, and free polyethylene glycol. This also lends itself well as a product that can be used for formulating highly sensitive and poorly water soluble drugs into self emulsifying drug delivery systems (SEDDS).
