Propylene glycol is a versatile and widely used ingredient in the cosmetic and skincare industry. Here are some common uses and functions of propylene glycol in cosmetics:

  • Humectant: Propylene glycol has humectant properties, meaning it attracts and retains moisture. It helps to keep products, such as creams and lotions, hydrated, preventing them from drying out.

  • Solvent: It serves as a solvent, helping to dissolve other ingredients in cosmetic formulations. This aids in the even distribution and stability of various components in products.

  • Emollient: Propylene glycol contributes to the overall texture of cosmetic products, providing a smooth and pleasing feel. It can enhance the spreadability of creams and lotions on the skin.

  • Penetration Enhancer: In some formulations, propylene glycol is used as a penetration enhancer, facilitating the absorption of other active ingredients into the skin.

  • Stabilizer: It helps stabilize the consistency and texture of cosmetic products, preventing them from separating or undergoing undesirable changes over time.

While propylene glycol is generally considered safe for use in cosmetics, some individuals may be sensitive or allergic to it. It's always recommended to patch test products containing this ingredient, especially if you have sensitive skin. Additionally, formulations with lower concentrations of propylene glycol are less likely to cause irritation.
