Pentylene glycol is primarily used as a solvent, meaning it aids in the solubilisation of ingredients within a formula. A few years ago, only the synthetic version derived from mineral oils was available and used in cosmetic care. Today, it is also available in a plant-based version, particularly in natural and/or certified organic products. It is then extracted from renewable plant sources such as corn or sugar cane.
