Propylene Glycol (CAS 57-55-6) is a remarkably versatile chemical compound, lauded for its functional properties as a humectant and solvent. These attributes make it an indispensable ingredient in a wide array of consumer products, from skincare formulations to food items and pharmaceuticals. NINGBO INNO PHARMCHEM CO.,LTD. is a prominent supplier of this essential chemical, ensuring high standards for its diverse applications.

Propylene Glycol as a Humectant

As a humectant, Propylene Glycol has the ability to attract and retain moisture from the surrounding environment. This property is vital in maintaining the hydration and consistency of various products:

  • Cosmetics and Personal Care: In lotions, creams, and serums, PG helps to draw moisture to the skin, keeping it hydrated and supple. This is a primary reason for its extensive use as a cosmetic ingredient. Its inclusion ensures products do not dry out, maintaining their texture and efficacy.
  • Food Industry: Propylene Glycol acts as a humectant in baked goods, confectionery, and other processed foods to prevent them from drying out, thus extending their shelf life and maintaining freshness. Its role as a food additive is well-established.
  • Pharmaceuticals: In liquid medications and some topical treatments, PG helps to maintain the moisture content of the formulation, ensuring stability and preventing degradation. This function is key to its role as a pharmaceutical excipient.

Propylene Glycol as a Solvent

The excellent solvency of Propylene Glycol makes it an effective medium for dissolving or dispersing other ingredients:

  • Flavor and Fragrance: PG is widely used as a solvent for flavors and fragrances in the food and cosmetic industries, ensuring even distribution and potency.
  • Pharmaceuticals: Many active pharmaceutical ingredients (APIs) are poorly soluble in water. PG serves as a co-solvent, increasing the solubility and bioavailability of these drugs in oral and injectable formulations.
  • Industrial Applications: Its ability to dissolve resins, dyes, and other chemicals makes it useful in paints, coatings, and inks, showcasing its broad utility in industrial applications.
