PEG-12 GLYCERYL DIMYRISTATE.

Valuable / SKIN CONDITIONING

PEG-12 Glyceryl Dimyristate is a sophisticated lipid primarily utilized for its ability to form stable liposomes, thereby optimizing the delivery and efficacy of active ingredients within precision skincare formulations. Additionally, it functions as a humectant, attracting and retaining moisture to support skin hydration and formula integrity.

Science

Mechanism of Action

This ingredient's mechanism relies on its amphiphilic molecular structure, featuring a hydrophilic polyethylene glycol (PEG) head and two hydrophobic lipid tails. This design enables spontaneous self-assembly into thermodynamically stable liposomes when dispersed in aqueous solutions. These microscopic lipid vesicles are crucial for encapsulating active molecules, enhancing their dermal penetration and ensuring more targeted delivery to specific sites, thus amplifying therapeutic outcomes. Furthermore, its PEG component imparts humectant properties, drawing atmospheric moisture into the skin to prevent transepidermal water loss and maintain hydration levels.

Stability

The liposomes formed by PEG-12 Glyceryl Dimyristate exhibit thermodynamic stability across a broad pH spectrum. This characteristic makes it highly effective for stabilizing inherently unstable active ingredients, such as pure Vitamin C, and for facilitating the solubilization of challenging components like cholesterol within a formula.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed PEG-12 Glyceryl Dimyristate as safe for use under current practices and concentrations, with reported concentrations up to 1.8% in leave-on body and hand products. It also holds FDA approval for general or limited use in food. However, due to its ethoxylation manufacturing process, there is a recognized potential for trace contamination with impurities such as ethylene oxide and 1,4-dioxane. Furthermore, PEGs should be applied with caution on compromised or damaged skin, as increased penetration could lead to irritation.
