Science
Mechanism of Action
This ingredient operates by lowering surface tension, effectively stabilizing immiscible oil and water phases as a surfactant and emulsifier. It functions as a solubilizer, enabling the integration of lipophilic or poorly soluble substances into aqueous systems. On the skin, it imparts a smoother texture through its emollient action and attracts moisture as a humectant, forming a protective layer to minimize water evaporation and optimize active ingredient distribution and efficacy.

Formulation
Stability
Polyethylene glycols (PEGs) and their derivatives generally exhibit commendable skin tolerance and resistance to microbiological degradation, potentially reducing the necessity for supplemental preservatives. The physical consistency of PEG derivatives progresses from liquid to solid with increasing degrees of polymerization, allowing for the creation of creamy textures by blending different forms. Water solubility and hygroscopicity diminish as the molar mass of the PEG increases.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG-45 Palm Kernel Glycerides, along with related PEGylated alkyl glycerides, safe for use in cosmetics when formulated to be non-irritating and applied within typical concentrations. While undiluted forms were observed to be irritating in primary animal studies, its safety in properly formulated cosmetic products is well-established.
