Propanediol (also known as 1,3-propanediol) is a glycol that can increase the absorption of ingredients (such as salicylic acid) to improve their effectiveness. Additionally, it offers moisturizing properties that can result in a smooth, dewy finish as the formula sets. Propanediol is a considered a safe, well-tolerated ingredient, not likely to cause sensitivity.

Propanediol is a versatile ingredient with additional properties that make it a favorable choice in skin care products, including its ability to boost the effectiveness of a preservative system within a formula. It can also serve as a solvent in a blend of ingredients.

Propanediol can be derived naturally from corn or created synthetically. It is a colorless to pale yellow, viscous (somewhat sticky) liquid and is chemically similar to 1,2-propanediol (propylene glycol).

In June 2018 the Cosmetic Ingredient Review Board reevaluated propanediol’s use in personal care products and concluded that it is safe. For leave-on products it was recorded in up to a 39.9% concentration (for a deodorant) - skin care products generally contain lower amounts than that.
