Science
Mechanism of Action
This ingredient functions by reducing the surface tension between disparate substances, enabling the formation of stable emulsions in which oil and water can coexist. Its surfactant properties also contribute to cleansing by helping to suspend and remove oils and dirt. While the oleamide component has known interactions with neurotransmitter systems, these effects are not directly associated with PEG-7 Oleamide's role or action within skincare applications.

Stability
PEG-7 Oleamide is expected to exhibit resistance to acidic conditions and moderate resistance to alkaline environments. It demonstrates good water solubility, though non-polar solvents such as benzene and mineral oils may provide superior dissolution. A 1% aqueous solution of a closely related compound, PEG-7 Cocoate, maintains a neutral pH range of 6.0 to 8.0.
Conflicts
- Must not be incorporated into cosmetic products where the formation of N-nitroso compounds (nitrosamines) is possible, requiring stringent minimization of primary amine impurities.
- Formulations must be meticulously controlled to minimize 1,4-dioxane impurity levels.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEG-7 Oleamide, among other alkoxylated fatty amides, safe for cosmetic use under current practices, provided formulations are non-irritating to the skin. A specific maximum concentration was not established as PEG-7 Oleamide was not reported to be in active use at the time of assessment. Key safety considerations include the strict minimization of impurities such as 1,4-dioxane and prevention of N-nitroso compound formation. No specific SCCS opinion was found, and the FDA lists it in the VCRP without reported cosmetic use.

Verdict
PEG-7 Oleamide is a valuable formulation aid, primarily as an emulsifier and surfactant, whose safety is confirmed by CIR with critical restrictions regarding impurity control to ensure non-irritating products.
