Propanediol

Propanediol (also known as 1,3-propanediol or 1,3-propylene glycol) is an organic solvent, emollient, and adsorption booster derived from corn starch or palm glycerin fermentation. A natural, colorless, and odorless propanediol is a perfect replacement for synthetic glycols in skin and hair care formulations.

It solubilizes and emulsifies oil, dirt, and makeup and rinses off the skin. In addition, 1,3-propanediol stimulates ceramide synthesis, restoring skin lipid barrier function, limiting transdermal water loss, and soothing irritation.

Furthermore, 1,3-propylene glycol boosts preservatives' effectiveness while acting as a humectant and sensation enhancer. As a result, it's a multifunctional bio-derived ingredient for high-end and eco-friendly skincare products.
