Overview/Definition
Propanediol is a versatile and multifunctional ingredient widely used in the skincare industry. It is a colorless, viscous liquid derived from corn sugar through a sustainable and renewable fermentation process. Propanediol is known for its ability to act as a solvent, humectant, emollient, and preservative, making it a valuable component in various skincare formulations.
This ingredient is often used as a natural alternative to propylene glycol, which is known to be more irritating to the skin. Propanediol is considered safer and gentler, especially for sensitive skin types. It is extensively used in cosmetic and skincare products due to its ability to enhance the efficacy of other ingredients, improve skin hydration, and provide a smooth, non-greasy feel.
Propanediol is recognized for its ability to dissolve difficult-to-dissolve ingredients, such as salicylic acid and ferulic acid, making it an excellent carrier for active cosmetic ingredients. It also helps to reduce the viscosity of products, improving their flow and application on the skin and hair. Additionally, it acts as a penetration enhancer, allowing beneficial ingredients to absorb deeper into the skin.
