Propanediol

Propanediol is derived from corn sugar. It is a natural alternative to propylene glycol. Propanediol can function as a solvent, humectant, and even an emollient when used in skincare.

Benefits:

•  Dissolves ingredients: It is an excellent solvent for harder to dissolve ingredients, like salicylic acid.

•  Decreases viscosity: A viscosity reducer is helpful in a variety of cosmetics, like conditioner, shampoo, foundation, mascara, body wash, hair spray, cleanser, and moisturizer, because it allows the formulas to flow well and makes them easier to use on the skin and hair.

•  Improves humectancy: As a humectant hair and skin conditioner, propanediol pulls moisture into the skin and encourages water retention. It offers moisturizing properties that can result in a smooth, dewy finish as the formula sets.

•  Safe for acne-prone & sensitive skin

•  Enhances preservative efficacy: Propanediol can also function as a preservative booster in skincare products.

•  Gives the product a non-sticky feel.
