Mechanism of Action
This ingredient operates by significantly lowering the surface tension of liquids, which is crucial for solubilizing oil-based components in water-based systems. It effectively removes impurities and excess sebum from the skin and hair, acting as a potent cleansing agent. Furthermore, it stabilizes immiscible phases within formulations and helps to draw and retain moisture in the stratum corneum.

Stability
Polyethylene glycols, including this derivative, exhibit robust stability against heat, acids, and alkalis. To prevent oxidative degradation, which can occur with prolonged exposure to air or elevated temperatures, minimizing oxygen contact or incorporating an antioxidant is recommended. Aqueous solutions are stable at ambient temperatures, and the ingredient itself resists hydrolysis and microbial proliferation during storage.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of PEG-82 Glyceryl Tallowate and similar PEGylated alkyl glycerides, provided they are formulated to be non-irritating and used within established concentration guidelines. It is deemed safe for rinse-off applications and safe for leave-on products at concentrations up to 10%, supported by ocular and sensitization assessments. While exhibiting low oral and dermal toxicity and minimal irritation to intact skin, it is crucial to note that sensitization and nephrotoxicity have been observed in studies involving burn patients, though not in those with healthy skin. Manufacturers are strongly advised to implement stringent quality control to minimize the presence of impurities such as ethylene oxide and 1,4-dioxane.
