Description

Triethylene glycol monododecyl ether (CAS 3055-94-5 ), also known commercially as Laureth-3, is a nonionic ethoxylated fatty alcohol surfactant. It reduces interfacial tension between oil and water phases, enabling stable emulsification. This chemical allows for effective soil removal across a range of formulated products. In home care and industrial cleaning formulations, it functions as a primary or co-surfactant in hard surface cleaners. It is frequently used in degreasers and laundry products where low-foam or controlled-foam profiles are required. Personal care manufacturers incorporate it as an emulsifier and solubilizer in creams and lotions. The compound is also utilized in rinse-off products for its gentle properties. Textile and leather processing operations use it as a wetting and scouring agent to improve substrate penetration during preparation. It is highly effective during dyeing stages to ensure even color distribution. In coatings and adhesive systems, it acts as a dispersing aid and wetting agent to improve pigment distribution and adhesion. Triethylene glycol monododecyl ether is supplied as a liquid or low-viscosity paste depending on temperature and concentration. It is available in technical grade for industrial and cleaning applications. The material is also offered as cosmetic-grade material meeting purity requirements for personal care use. Bulk supply is standard in drums and intermediate bulk containers (IBCs) for large scale manufacturing. Contact us for supply of Triethylene glycol monododecyl ether Request Quote
