Propylene Carbonate

Description

Propylene Carbonate is a versatile synthetic ingredient widely used in cosmetic and skincare formulations. This colorless, odorless liquid is prized for its excellent solvency properties and ability to enhance the penetration of active ingredients into the skin. With a molecular formula of C4H6O3, Propylene Carbonate is classified as a cyclic carbonate ester.

In skincare products, Propylene Carbonate primarily functions as a solvent and emollient. It effectively dissolves both oil-soluble and water-soluble ingredients, making it invaluable in creating stable, homogeneous formulations. Its low viscosity and high polarity contribute to improved spreadability and texture of products.

Propylene Carbonate is particularly beneficial in formulations containing active ingredients like retinoids, peptides, and antioxidants, as it can enhance their delivery into deeper skin layers. It also exhibits humectant properties, helping to maintain skin hydration.

Safety assessments have shown Propylene Carbonate to be non-irritating and well-tolerated by most skin types. It is biodegradable and considered environmentally friendly. However, as with any ingredient, patch testing is recommended for individuals with sensitive skin or known allergies.
