Triethylene glycol monooctadecyl ether

Triethylene glycol monooctadecyl ether, identified by CAS 4439-32-1, is commercially recognized as STEARETH-3. It is a short-chain ethoxylated fatty alcohol combining a C18 stearyl backbone with three ethylene oxide units.

This chemical functions primarily as a nonionic emulsifier and wetting agent across personal care, cleaning, and industrial textile applications. In cosmetic formulations, it is used to stabilize oil-in-water emulsions in creams and lotions.

Its specific HLB value supports co-emulsifier blending with higher-ethoxylate grades in conditioners and skin care. Textile and leather processing operations use it as a wetting and scouring agent to improve fiber penetration during dyeing.

In home care and industrial cleaning formulations, it aids the dispersion of oils and soils on hard surfaces and fabric substrates. It also functions as a moisturizing component in leave-on skin care products for surface hydration.

The material helps retain moisture in emollient systems and is typically supplied as a white to off-white waxy solid or flake at ambient temperature. It maintains stability across various industrial and commercial environments.

Standard grades include cosmetic and personal care grade meeting common industry purity benchmarks. Technical grade is also available for industrial textile and cleaning applications where high-performance surfactants are required.

The product is manufactured to meet rigorous quality standards for consistency and performance in diverse formulations. Packaging is commonly available in 25 kg bags or drums to suit different manufacturing scales.
