What is Tetraethylene glycol?
Tetraethylene glycol (CAS 112-60-7), commonly abbreviated as TEG, is a mid-chain polyethylene glycol; also marketed as PEG-4 in cosmetic and personal care contexts.
Where is Tetraethylene glycol used?
- Pharmaceutical: solvent and co-solvent
- Personal care: humectant
- Cosmetic formulations: solvent carrier for active ingredients in creams, serums and cleansing products
- Polymer chemistry: reactive diol for cross-linking and curing polyurethane and epoxy systems
- Specialty plastics: plasticizer and processing aid
- It supports stable dosing in topical and oral preparations.
Good to know: Pharmaceutical and cosmetic supply chains typically require material meeting USP or Ph. Eur. compendial standards.
Commercial specifications
- Drum and IBC quantities
- Technical and high-purity grades
