TRIPROPYLENE GLYCOL

Description

Tripropylene glycol (TPG) is a versatile organic compound widely used in skincare and cosmetic formulations. This colorless, odorless liquid is a member of the glycol family and acts as an effective humectant and solvent. TPG has a molecular formula of C9H20O4 and is synthesized through the polymerization of propylene oxide.

In skincare applications, TPG primarily functions as a moisture-retaining agent, helping to keep the skin hydrated by attracting and binding water molecules. Its hygroscopic properties make it valuable in products designed for dry or dehydrated skin. Additionally, TPG serves as an excellent solvent, enhancing the solubility and stability of various active ingredients in formulations.

TPG is generally considered safe for topical use and is approved by regulatory bodies for cosmetic applications. It has a low potential for skin irritation and is well-tolerated by most individuals. The ingredient's ability to improve product texture and spreadability contributes to its popularity in lotions, creams, and serums.

When formulating with TPG, it's typically used in concentrations ranging from 1% to 5%, depending on the product type and desired effects. Its compatibility with a wide range of other cosmetic ingredients makes it a valuable component in multi-functional skincare products.
