PEG-14m

PEG / Ethoxylated

What is PEG-14m?

PEG-14M is a polyethylene glycol polymer with an average molecular weight of approximately 14,000, synthesized through the polymerization of ethylene oxide units. This results in a water-soluble, non-volatile substance that appears as a clear, viscous liquid or soft solid at room temperature. In cosmetic formulations, it belongs to the category of conditioning and structuring agents, commonly found in creams, lotions, shampoos, and pressed powders. It functions by forming flexible films that bind solid particles together, enhancing the cohesion and durability of compacts or sticks. As an emulsion stabilizer, it reinforces the interface between oil and water phases, reducing droplet merging and preventing separation over time. Its viscosity controlling properties allow precise adjustment of product thickness, ensuring smooth dispensing, even suspension of particles, and desirable sensory feel during application. Due to its large size, it primarily remains on the skin surface without deep penetration.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Binder
Helps hold solid ingredients together to form cohesive tablets, compacts, or sticks, improving pressability, integrity, and wear of the finished product.
Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Strengthens product integrity by binding solids into durable forms like powders and sticks.

Prevents emulsion breakdown for longer-lasting stability in creams and lotions.

Optimizes thickness for improved spreadability and user-friendly texture.

Who May Benefit Who Should Avoid
Users of pressed powders or makeup needing wear-resistant formulas.
People sensitive to ethoxylated compounds or PEG derivatives.
Individuals preferring stable lotions and creams that resist separation.
Individuals preferring strictly natural or plant-based ingredients.
Those seeking smooth, easy-to-apply products with consistent consistency.
Users concerned about synthetic polymers from petrochemical origins.

Safety Notes

  • Cosmetic Ingredient Review deems it safe for use in cosmetics when formulated to limit impurities.
  • Typically shows low potential for skin irritation in standard concentrations.
