PEG-2 SORBITAN TRIOLEATE.

Insufficient Data / SURFACTANT - EMULSIFYING

PEG-2 Sorbitan Trioleate is a versatile ethoxylated ester that functions as an emulsifier and surfactant. It facilitates the stable blending of oil and water, and can aid in solubilizing hydrophobic compounds within aqueous formulations. Furthermore, its PEG component contributes to skin hydration by retaining moisture.

Science

Mechanism of Action

This ingredient primarily operates through surface tension reduction. As an emulsifier, it stabilizes oil-in-water or water-in-oil formulations, preventing phase separation. Its surfactant properties enable it to interact with both oil and water, lifting impurities for effective cleansing. Additionally, it can enhance the dissolution of poorly water-soluble active ingredients and improve their bioavailability. The polyethylene glycol moiety can draw and bind water molecules to the skin, thus reducing transepidermal water loss and promoting enhanced hydration.

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
25%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed polysorbates, including PEG-2 Sorbitan Trioleate, as safe for cosmetic use when formulated to be nonirritating, up to a maximum concentration of 25%. It should not be applied to damaged skin. It is important to note that in 2015, PEG-2 Sorbitan Trioleate was listed as 'not reported to be in current use' and had an 'Insufficient Data Announcement' by the CIR. Trace amounts of 1,4-dioxane, a by-product of the ethoxylation process, may be present; however, purification steps can effectively control its levels. The FDA generally considers polysorbates safe for various applications, though a specific approval for this ingredient is not explicitly stated.

Verdict

Insufficient Data

While its functions as an emulsifier and surfactant are well-understood, specific efficacy and safety data for PEG-2 Sorbitan Trioleate itself are limited, necessitating careful consideration for precision formulations.
