What is Triethylene glycol monododecyl ether?
Triethylene glycol monododecyl ether (CAS 3055-94-5), also known commercially as Laureth-3, is a nonionic ethoxylated fatty alcohol surfactant.
Where is Triethylene glycol monododecyl ether used?
- Home care and industrial cleaning: primary or co-surfactant in hard surface cleaners
- Degreasers and laundry products: low-foam or controlled-foam profiles
- Personal care: emulsifier and solubilizer in creams and lotions, also in rinse-off products
- Textile and leather processing: wetting and scouring agent for substrate penetration, and even color distribution during dyeing
- Coatings and adhesives: dispersing aid and wetting agent for pigment distribution and adhesion
- It reduces interfacial tension between oil and water phases, enabling stable emulsification.
Commercial specifications
- Cosmetic-grade material meeting purity requirements for personal care use
- Bulk supply in drums and intermediate bulk containers (IBCs)
