Tetraethylene glycol monomethyl ether

Tetraethylene glycol monomethyl ether (CAS 23783-42-8 ) is a polyethylene glycol-based ether solvent and humectant used across personal care, pharmaceutical, and industrial formulation.

Its combination of hygroscopic retention and solvent capacity makes it a practical choice for formulators working with polar and semi-polar actives in various chemical applications.

In personal care formulations, it functions as a humectant and solubilizer in skin creams, serums, and hair care products where moisture retention and ingredient compatibility are both required.

Pharmaceutical manufacturers use it as a carrier solvent in topical and semi-solid dosage forms, helping to dissolve active ingredients and improve skin penetration without aggressive solvency.

Printing ink formulators incorporate it to control viscosity and drying behavior in water-based and specialty ink systems to ensure consistent performance during the application process.

In metalworking and lubricant applications, it serves as a coupling agent and co-solvent in water-miscible cutting fluids and corrosion-inhibiting formulations for industrial machinery.

Tetraethylene glycol monomethyl ether is supplied as a clear, low-viscosity liquid. It is available in technical and high-purity grades suited to industrial and personal care applications.

Packaging typically ranges from drums to IBC containers, with smaller quantities available for laboratory and development use to meet specific manufacturing and research requirements.
