Science
Mechanism of Action
As a PEGylated alkyl glyceride, PEG-6 Palmitate stabilizes emulsions by reducing the interfacial tension between immiscible phases, thereby creating uniform textures. On the skin, it conditions by forming a lubricating film on the surface or within the stratum corneum, which helps to mitigate flaking and improve smoothness. Additionally, it possesses humectant properties, drawing and binding water molecules via hydrogen bonds to enhance skin hydration and reduce transepidermal water loss.

Stability
PEG Palmitate exhibits general stability but is susceptible to hydrolysis under strong acidic or alkaline conditions. Related palmitate esters show optimal stability around pH 5.6 to 7.0, with reduced stability observed at pH 4.0 and 8.0.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG compounds, including PEGylated alkyl glycerides like PEG-6 Palmitate, as safe for use in cosmetic formulations. They specifically noted PEG diesters, when properly formulated, are non-irritating, and removed previous cautions regarding use on damaged skin. While the raw material in solid form may be an irritant, this does not translate to finished cosmetic products.
