SORBETH-60 TETRAOLEATE.

Valuable / SURFACTANT - EMULSIFYING

Sorbeth-60 Tetraoleate is a hydrophilic, nonionic surfactant and emulsifying agent primarily used to stabilize oil-in-water formulations. It facilitates the harmonious blending of typically immiscible components like oils and water, ensuring product integrity and texture. Beyond its stabilizing role, it also aids in cleansing and is noted for potential moisturizing benefits.

Summary

Emulsifying Surfactant

Science

Mechanism of Action

As a surfactant, Sorbeth-60 Tetraoleate effectively lowers the interfacial tension between disparate phases, enabling the creation and maintenance of stable emulsions. This property also facilitates the solubilization of other ingredients that would not normally dissolve in a given solvent. In cleansing applications, it allows water to effectively mix with and lift oils and dirt from the skin and hair, making them easier to rinse away. Additionally, research suggests it may contribute to skin moisturization and offer relief from irritants.

25%
Sensitization risk Low

The CIR Expert Panel has deemed Sorbeth-60 Tetraoleate safe for cosmetic use at concentrations up to 25%, provided it is formulated to be non-irritating. An earlier caution regarding use on damaged skin was subsequently removed. Trace amounts of 1,4-dioxane, a by-product of its manufacturing, can be present but are controlled through purification processes. While direct SCCS status was not specified, related polysorbates have FDA approval for certain food applications.
