Science
Mechanism of Action
This ingredient functions primarily as a nonionic surfactant, reducing the surface tension between different phases (like oil and water) within a cosmetic formulation. Its emulsifying properties help to stabilize oil-in-water or water-in-oil emulsions, ensuring uniform dispersibility and product integrity.

Key findings
- 01 No specific clinical studies evaluating the efficacy of PEG-2 DIOLEATE were identified. However, a study on related PEG diesters indicated that PEG-12 dioleate at 5% concentration enhanced the dermal penetration of ketoprofen through mouse skin with an enhancement ratio (ER) of 1.54±0.22, whereas PEG-8 dioleate at 5% did not demonstrate this effect.

The Formula
Formulation
Stability
PEG-2 DIOLEATE exhibits solubility in non-polar solvents such as isopropyl alcohol, acetone, and mineral oil. Due to its low number of ethylene oxide units, its water solubility is limited. It is effectively employed as a nonionic surfactant in both oil-in-water and water-in-oil emulsion systems to bolster dispersibility and overall product stability, often found in sunscreen formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that PEG diesters, including PEG-2 DIOLEATE, are safe for use in cosmetics when formulated to be non-irritating. While a specific maximum concentration for PEG-2 DIOLEATE was not established, related PEG diesters were reported in formulations at 15% or less. General animal and human studies on PEG diesters indicate minimal to no irritation in ocular and dermal assessments, and no evidence of dermal sensitization. No specific SCCS opinion or FDA status for cosmetic use is available in the provided data.

Verdict
PEG-2 DIOLEATE is a valuable formulation aid, primarily as a surfactant and emulsifier, with a generally low safety risk based on its class assessment, though specific efficacy data for this variant is limited.
