Propanediol (1, 3 propanediol)

Propanediol 1,3 also referred to as Propanediol, is a natural, green, propylene glycol alternative derived from corn sugar, used as a humectant, hair and skin conditioner, preservative booster, and solvent with a light, non-sticky, slightly dry skin feel.

Propanediol increases hydration when used in hair and body products, and at 5%, performs better than propylene glycol and butylene glycol. When combined with glycerin, Propanediol shows a synergistic effect that reduces the tackiness of glycerin, while offering the benefits of increased levels of hydration. At levels up to 75%, it shows low potential to irritate or sensitize skin.

In surfactant systems, Propanediol helps to increase the clarity of surfactant systems and viscosity while decreasing the amount of salt necessary to thicken a product. It improves flash foam, and produces more elegant systems with creamier lather and denser foam.

In hair care products, such as shampoo, conditioner, leave on conditioners, or styling aids, it offers a cleaner feeling after rinsing while increasing moisturization, improving detangling, reducing static, and improving wet and dry combing.

In all products, it decreases the freezing point and increases stability in freeze/thaw and heated tests.

Propanediol helps to boost the efficacy of preservatives. Its efficacy was demonstrated when combined with preservatives containing phenoxyethanol against yeast, gram-positive, and gram-negative organisms, as well as mold.

Propanediol is an excellent solvent for harder to dissolve ingredients like salicylic acid, ferulic acid, allantoin, and ascorbic acid.
