PEG-400, also known as polyethylene glycol 400, is a versatile solvent commonly used in various industries and applications. It is a clear, colorless liquid with a low viscosity that mixes well with water and many organic solvents.

PEG-400 is valued for its excellent solubility properties, making it useful in the formulation of pharmaceuticals, personal care products, and industrial applications. It is frequently employed as a solvent or carrier agent for active ingredients, excipients, and additives due to its ability to dissolve a wide range of substances.

In the pharmaceutical industry, PEG-400 plays a vital role in formulating oral liquids, suspensions, and topical preparations. Its high solubility power allows for enhanced drug delivery and improved bioavailability of active compounds. Additionally, PEG-400 serves as an effective vehicle for injectable medications and has been utilized in some intravenous formulations.

PEG-400’s stability and non-toxic nature make it suitable for use in cosmetics and personal care products as well. It can be found in skincare creams, lotions, ointments, haircare products, and many other cosmetic formulations. PEG-400 acts as an emollient that helps to soften the skin, improve product spreadability, and enhance absorption.

In industrial applications such as adhesives or coatings, PEG-400 serves as a solvent that aids in dissolving various resins or polymers to achieve desired viscosity and consistency.

It’s worth noting that although PEG-400 is generally considered safe for use in regulated concentrations within its intended applications; it may cause skin irritation or allergic reactions in some individuals. Precautions should be taken to handle it safely using adequate protective measures when necessary.

Overall, PEG-400’s versatility as a solvent makes it widely used in numerous industries where solubility, stability, and compatibility are important factors. Its ability to dissolve a wide range of substances and mix well with other solvents contributes to its popularity as a solvent of choice in various formulations.
