Propylene Glycol / Monopropylene Glycol USP

???? What is Propylene Glycol?

Propylene Glycol is a humectant and solvent widely used in natural cosmetics, perfumery, and technical formulations. It is known for its bactericidal and fungicidal properties, and its versatility allows it to dissolve both aqueous (water-soluble) and fatty (liposoluble) solutions without altering the properties of the ingredients it interacts with — only the texture or consistency of the final product.

???? Main Properties

• Humectant: Retains moisture and prevents the drying of the skin’s outer layer.
• Emollient: Protects and softens the skin by forming a light barrier on the epidermis.
• Natural preservative: At high concentrations (15–30%), it acts as an effective preservative, comparable to ethanol.
• Universal solvent: Efficiently dissolves both water-based and oil-based active ingredients, such as essential oils and vitamins A or D.
• Stabilizer: Improves the homogeneity of cosmetic emulsions and reduces viscosity compared to glycerin.
• Plasticizer: Adds flexibility and improves the texture of gels, creams, and lotions.

???? Common Uses of Propylene Glycol

This ingredient is one of the most versatile compounds in natural and industrial cosmetics. It is used as a solvent, humectant, and stabilizer in:

• Air fresheners and aromatic sprays
• Facial creams and body lotions
• Deodorants and lip balms
