Science
Mechanism of Action
This ingredient operates by reducing surface tension, enabling immiscible oil and water phases to blend seamlessly and form stable emulsions in cosmetic matrices. As an emollient, it contributes to a softer skin texture. Furthermore, PEGs like PEG-15 Oleate are known to attract and retain moisture within the stratum corneum, forming hydrogen bonds with water molecules to boost skin hydration and minimize transepidermal water loss.

Stability
PEG-15 Oleate demonstrates robust stability when exposed to heat, acidic, and alkaline conditions, making it suitable for a diverse range of cosmetic formulations. As an effective emulsifier, it facilitates the creation of stable oil-in-water or water-in-oil systems. With an estimated HLB value of approximately 15.1, it is expected to be readily water-soluble or dispersible, aiding its incorporation into aqueous and emulsified products.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEGs and their fatty acid esters, including PEG-15 Oleate, are safe for cosmetic applications when formulated to be non-irritating. Strict adherence to current Good Manufacturing Practices (cGMPs) is crucial to minimize potential contamination by trace impurities such as 1,4-dioxane and heavy metals. It is pertinent to note that PEG 300 Oleate, sharing the same CAS Reg. No. 9004-96-0, is approved by the FDA as a secondary direct food additive, indicating a recognized level of safety for specific uses.
