Science
Mechanism of Action
As a surfactant, SORBETH-20 TETRAISOSTEARATE effectively reduces the surface tension between oil and water, allowing them to form stable emulsions. It functions as an emulsifying agent, a cleansing agent by facilitating the removal of oil and dirt, and a solubilizing agent to help disperse other ingredients in solvent systems.

Stability
No specific optimal pH range for the stability of SORBETH-20 TETRAISOSTEARATE has been identified. However, analogous polysorbate ingredients typically maintain stability within mildly acidic to neutral pH environments, commonly observed between pH 5.5 and 6.2.
Safety
Safety Profile
The CIR Expert Panel concluded that the group of PEG Sorbitan/Sorbitol Fatty Acid Esters, including SORBETH-20 TETRAISOSTEARATE, is safe for use in cosmetics at concentrations up to 25%, given that the formulations are non-irritating. Earlier concerns regarding renal toxicity from PEGs on damaged skin have been addressed and largely dismissed due to evidence indicating minimal dermal penetration of low-molecular weight PEGs. Trace amounts of 1,4-dioxane, a byproduct of the ethoxylation process, may be present but can be controlled through purification steps and are monitored by the FDA.
