Propanediol

Propanediol

Propanediol (also known as 1,3-propanediol) is an organic solvent, emollient, and adsorption booster derived from corn starch. It solubilizes and emulsifies oil, dirt, and makeup and rinses off the skin.
1,3-propanediol stimulates ceramide synthesis, restoring skin lipid barrier function, limiting transdermal water loss, and soothing irritation.
