PEG-22/Dodecyl Glycol Copolymer

PEG / Ethoxylated

What is PEG-22/Dodecyl Glycol Copolymer?

PEG-22/Dodecyl Glycol Copolymer is a synthetic polymer created by reacting polyethylene glycol with 22 ethylene oxide units to dodecyl glycol, a fatty alcohol derivative. This results in a hydrophilic-lipophilic molecule ideal for cosmetic formulations, particularly in creams, lotions, and serums within the rinse-off and leave-on categories. It functions primarily by lowering interfacial tension between immiscible phases, such as oils and water, to form stable emulsions that resist breaking down over time. As an emollient, it lubricates the skin surface, enhancing product glide and leaving a non-greasy finish. Its structure allows it to thicken formulations subtly while maintaining clarity and preventing phase separation, making it valuable in water-in-oil or oil-in-water systems used for daily skincare routines.

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.
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Benefits

Helps maintain product stability by preventing oil-water separation in emulsions.

Provides a smooth, softening effect on skin during application.

Supports even distribution of active ingredients in formulas without greasiness.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Individuals using emulsion-based moisturizers for consistent texture.
People sensitive to ethoxylated compounds or PEG derivatives.
Those seeking lightweight emollients for daily skincare routines.
Those preferring silicone-free or fully natural formulations.
Users preferring non-comedogenic ingredients in lotions or creams.
Individuals with known reactions to synthetic surfactants.

Safety Notes

  • Generally considered safe for cosmetic use at typical concentrations with low comedogenic potential.
  • May contain trace impurities like 1,4-dioxane if not properly purified, though regulated in quality products.
