Methoxy PEG-22/Dodecyl Glycol Copolymer

PEG / Ethoxylated

What is Methoxy PEG-22/Dodecyl Glycol Copolymer?

Methoxy PEG-22/Dodecyl Glycol Copolymer is a synthetic polymer created through the copolymerization of methoxy polyethylene glycol (PEG-22) and dodecyl glycol monomers. This ethoxylated compound belongs to the class of PEG derivatives commonly employed in personal care formulations, particularly in hair styling products, lotions, and creams. It serves as a multifunctional ingredient by forming flexible films or networks that reinforce the structure between oil and water phases. In emulsions, it strengthens interfacial layers to resist droplet merging; as a suspending agent, it creates a viscous matrix holding pigments or actives in place; and for viscosity control, it modulates flow properties for better spreadability and stability during storage and use. Derived from petrochemical sources, it undergoes purification to minimize impurities.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Suspending agent
Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Improves emulsion durability by preventing oil-water separation and enhancing product shelf life.

Maintains uniform dispersion of insoluble components like pigments for consistent application.

Optimizes product thickness for smooth texture and easy dispensing in various formulations.

Who It's For

Who May Benefit Who Should Avoid
Users of emulsified skincare like lotions needing long-term stability.
Those with known sensitivity to PEG or ethoxylated polymers.
Individuals applying products with suspended particles such as exfoliants or colorants.
Users preferring silicone- and PEG-free formulations.
People preferring creams with adjustable textures for comfortable daily routines.
Individuals avoiding synthetic copolymers due to personal preferences.
