Propylene Glycol

Propylene Glycol (PG) is a clear, colorless, nearly odorless liquid widely used as a solvent, humectant, and carrier in the fragrance, cosmetic, pharmaceutical, and personal care industries. It has excellent solvency and is completely miscible with water, alcohol, and many organic solvents, making it a versatile ingredient in a wide range of formulations. Propylene Glycol helps dissolve fragrance materials, retain moisture, and improve the consistency and stability of finished products. It is commonly used in perfumes, body mists, room sprays, cosmetics, and personal care products. Key characteristics: Clear, colorless liquid Nearly odorless Excellent solvent and carrier Hygroscopic (helps retain moisture) Miscible with water, alcohol, and many organic solvents Good chemical stability Low viscosity Compatible with a wide range of cosmetic and fragrance ingredients Applications: Perfumes and body mists Room and linen sprays Air fresheners Cosmetic and skincare products Hair care formulations Pharmaceutical preparations In perfumery, Propylene Glycol is used as a solvent and carrier to dissolve fragrance ingredients and improve formulation stability. Compared with Dipropylene Glycol (DPG), PG evaporates more quickly, making it better suited for water-based fragrance products and sprays, while DPG is generally preferred for oil-based perfumes and reed diffusers due to its slower evaporation and better fragrance longevity.
