Cosmetic Grade High Purity Propanediol 1,3
Products Description
Propanediol 1,3 is a natural, skin-friendly preservative-boosting humectant for all kinds of formulations. It is made from renewable corn sugar fermentation. Has excellent sensory characteristics & is environmentally sustainable. It is naturally-derived.
Propanediol 1,3 (referred to as Propanediol hereafter) 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 increases 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 may 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.

What is PROPANEDIOL used for?
Propanediol is widely used in products such as cleansers, toners, eyeliners, and foundations. Propanediol leaves the skin radiant and glowing without any negative effects.
- In skin care, Propanediol is known for softening and soothing the skin. It acts as an emollient and retains moisture on the skin - making it healthy and supple and promoting anti-aging properties. Further, propanediol also prevents water loss by forming a protective barrier on the skin
- For hair care, it is known to deeply hydrate the scalp and makes hair softer and smoother. Propanediol is a great conditioner and also promotes product absorption in formulations
