Propanediol (from corn) vs. Propylene Glycol

Thank you for your question. There seems to be a slight confusion regarding the names.

Propanediol derived from corn is typically 1,3-Propanediol. This is a different chemical compound from Propylene Glycol, which is chemically known as 1,2-Propanediol.

While both are glycols and serve similar functions in formulations, they have key differences:

• Source: 1,3-Propanediol (like the one derived from corn) is often produced through the fermentation of glucose, making it a naturally derived ingredient. Propylene Glycol (1,2-Propanediol) is typically synthesized chemically.
• Properties & Skin Feel: Both act as effective humectants (helping skin retain moisture) and solvents. However, 1,3-Propanediol is often noted for having a better, less sticky skin feel compared to Propylene Glycol. It can also enhance the moisturizing effect of other humectants like glycerin and can act as a preservative booster.
• Usage: Propylene Glycol has a long history of use in cosmetics, pharmaceuticals, and even food. 1,3-Propanediol is increasingly used in cosmetics as an alternative, especially in formulations aiming for a more natural profile.

Brands are indeed increasingly using 1,3-Propanediol due to its natural origin and favorable skin feel properties.

Regarding availability, MySkinRecipes does offer Propanediol (1,3-Propanediol), which can be used as an alternative to Propylene Glycol in many applications.
