Propanediol 1,3

Propane-1,3-diol, more often called propanediol, is a simple organic chemical and is a member of the class of compounds known as diols, in which two hydrogen atoms in a propane molecule have been replaced by hydroxyl groups (-OH) at either end of its carbon chain. A colorless viscous liquid, well soluble in water, with a relatively rather high boiling point of 210°C, it finds useful application in many industries. In addition to its use as a solvent and antifreeze, propane-1,3-diol is used in the production of polymers, mainly applied materials such as plastics and coatings.
This protic nature can let propane-1,3-diol participate in extensive interactions with many chemical species, hence becoming of huge service in a wide scale of formulation applications. It also acts as a metabolite in biological systems, as it participates in a number of metabolic pathways. Propanediol has increasingly seen acceptance in cosmetic applications due to its status as a natural and sustainable substitute for the synthetic solvent propylene glycol. Generally, propanediol is sourced from corn sugar. It is preferred due to its low environmental impact and has been duly certified by Ecocert, being very attentive to the dictates of green chemistry.
Propanediol is an active humectant that acts to attract and retain moisture in the skin care formulation; besides that, it enhances the overall sensory feel of products by giving a smooth texture, thus improving skin feel. With its multi-functionality, along with a sustainable profile, this ingredient has great value in cosmetic and personal care formulation for hydration and enhancing the general efficacy of a product.
