UNIOX® ST-40E
About Sorbeth‑40 Tetraoleate
Sorbitol-derived nonionic surfactants are widely used in cleansing formulations to improve solubilization, foam quality, formulation stability, and sensory performance. They help formulators incorporate emollient oils into aqueous systems while maintaining product clarity and performance.
UNIOX® ST‑40E is a nonionic surfactant based on Sorbeth‑40 Tetraoleate. It is designed for cleansing formulations and contributes to improved after‑wash feel, viscosity building, foam quality, and formulation stability.
Its high solubilization power enables emollient oils to be incorporated into shampoos, body washes, and other cleansing systems while supporting enhanced moisture retention and consumer sensory experience.
