Difference between Propanediol and Propylene Glycol

Propanediol and Propylene Glycol are both types of glycols used in formulations, but they have some key differences:

• Origin: Propylene Glycol is typically derived from petrochemicals. Propanediol, on the other hand, is often marketed as a natural alternative because it can be derived from renewable sources like corn.
• Safety Claims: Manufacturers of Propanediol often promote it as being safer or less irritating than Propylene Glycol due to its natural origin. However, current research does not conclusively prove that Propanediol is inherently safer or less likely to cause irritation than Propylene Glycol. Skin sensitivity is highly individual.
• Cost: Propanediol is generally significantly more expensive than Propylene Glycol.
• Properties and Uses: Propylene Glycol is a versatile ingredient used as a lubricant, viscosity reducer, solvent, and humectant (moisture retainer) in cosmetics, pharmaceuticals, and food products. It helps make creams and gels smooth, improves stability, and reduces water loss from the skin.

Regarding availability, the company currently does not have plans to stock or sell Propanediol.
