Polypropylene Glycol

Description

Polypropylene glycol (PPG) is a versatile synthetic compound widely used in cosmetic and skincare formulations. This clear, colorless liquid belongs to the glycol family and shares similarities with propylene glycol, but with a larger molecular structure. PPG functions primarily as a humectant, attracting and retaining moisture to help hydrate the skin.

In skincare products, PPG serves multiple purposes. It acts as an emollient, softening and smoothing the skin's surface. Its moisture-binding properties help maintain skin hydration, potentially reducing the appearance of fine lines and improving overall skin texture. PPG also works as a solvent, aiding in the dispersion of other ingredients within formulations.

The ingredient is generally well-tolerated by most skin types and is considered non-irritating at typical concentrations used in cosmetics. PPG's low molecular weight allows for easy absorption into the skin without leaving a greasy residue. It can enhance the penetration of other active ingredients, potentially improving their efficacy.

Formulators often choose PPG for its stability, compatibility with various ingredients, and ability to improve product texture and spreadability. Its multifunctional nature makes it a valuable component in moisturizers, serums, and other skincare products.
