Propylene Glycol / Monopropylene Glycol USP

What is Propylene Glycol?

Propylene glycol is a humectant and solvent. It is attributed with bactericidal and fungicidal properties. It is suitable for diluting aqueous solutions (water-soluble) or fatty solutions (liposoluble). It does not alter the properties of the ingredients it interacts with, only the texture may vary.

At high concentrations, it acts as an effective preservative, almost similar to ethanol. It is an excellent carrier for active ingredients that do not dissolve in water, such as volatile oils or Vitamins A and D.

Additionally, it is considered a good emollient, preventing the drying of the stratum corneum of the epidermis and protecting the skin.

It has a stabilizing effect on cosmetic emulsions and is also used as a plasticizing agent in formulations.

It is incorporated in the aqueous phase of emulsions and contributes less viscosity to formulas than glycerin.
